  • flex and jsf access the same instance of bean

    - by David
    i integrate a flex app in a jsf-icefaces app (in a jspx site with the ice:outputmedia-tag) and want to access the same instance of a bean from flex by remote, that jsf inject. i already connect with blazeds to a java-bean. this bean - like all other beans - get other beans by injection of jsf, but when i access the bean by remote from flex it doesnt hold the injected beans (like localizer and accesmanager, both session scoped) and i can't connect to the jsf session (FacesContext.getCurrentInstance() is null). this is because flex create a new instance of the bean and it’s not the same current instance, that jsf inject, i think. i can connect from flex to the database by create a new entity manager in the java bean, but that's not what i want, because it's again another entity manager...i want persist and get data over the accessmanager-bean. i know exadel fiji and flamingo, but i couldn't work with fiji, because my jsf app include the icefaces components and then it doesn't work with richfaces which fiji needs. and flamingo work only with jboss seam and spring. is it right? i also read about the spring-flex-integration, but the jsf application did not create with spring and i don't want to integrate spring in such a large jsf app. yesterday i read about the FlexFactory interface. this interface i have to implement in my own Factory and set it in the service-config.xml of blazeds as a factory read this. i still implement my own factory but i only get application scoped beans over the servlet context which i get over FlexContext.getServletContext().getAttribute("Bean"); and not session scoped beans... i hope there is a chance to connect throw flex and jsf... thanks!

  • Which Computer Organization & Architecture book is good for me?

    - by claws
    I'm always interested in learning the inner working of things. I started with C programming and then learnt Operating systems (from stallings) and then linkers & loaders and then assembly language after reading these now I want to go into little more depth. Computer Architecture. I feel that makes everything clear. As per SO archives these are the two good books: Computer Architecture: A Quantitative Approach, 4th Edition Computer Organization and Design, Fourth Edition, ~ David A. Patterson, John L. Hennessy But I've browsed through the contents of these books and found that they don't exactly meet my needs. I want to learn more about caches, Memory Management Unit , mapping b/w virtual memory & physical memory I'm no way interested in other ISAs like MIPS etc.. I'm IA32 and X86-64 fan and I want to stick to it. I'm not a hardware developer I don't want to details like circuit diagrams or How is L1, L2 & L3 caches are implemented? I want to know the parallel processing technologies like HyperThreading at the architecture level but again I don't want to design them. I liked the table of Contents of - Computer Architecture: A Quantitative Approach, 4th Edition but Quantitave Approach? Seriously?? I want to know the details of current technologies and I dont want to spend reading 200 pages of outdated old technologies ( I experienced this while learning ASM}

  • WebSVN with VisualSVN Server, anyone gotten authentication to work?

    - by Lasse V. Karlsen
    I have a VisualSVN Server installed on a Windows server, serving several repositories. Since the web-viewer built into VisualSVN server is a minimalistic subversion browser, I'd like to install WebSVN on top of my repositories. The problem, however, is that I can't seem to get authentication to work. Ideally I'd like my current repository authentication as specified in VisualSVN to work with WebSVN, so that though I see all the repository names in WebSVN, I can't actually browse into them without the right credentials. By visiting the cached copy of the topmost link on this google query you can see what I've found so far that looks promising. (the main blog page seems to have been destroyed, domain of the topmost page I'm referring to is the-wizzard.de) There I found some php functions I could tack onto one of the php files in WebSVN. I followed the modifications there, but all I succeeded in doing was make WebSVN ask me for a username and password and no matter what I input, it won't let me in. Unfortunately, php and apache is largely black magic to me. So, has anyone successfully integrated WebSVN with VisualSVN hosted repositories?

  • How to return DropDownList selections dynamically in ASP.NET?

    - by salvationishere
    This is probably a simple question but I am developing a web app in C# with DropDownList. Currently it is working for just one DropDownList. But now that I modified the code so that number of DropDownLists that should appear is dynamic, it gives me error; "The name 'ddl' does not exist in the current context." The reason for this error is that there a multiple instances of 'ddl' = number of counters. So how do I instead return more than one 'ddl'? Like what return type should this method have instead? And how do I return these values? Reason I need it dynamic is I need to create one DropDownList for each column in whatever Adventureworks table they select. private DropDownList CreateDropDownLists() { for (int counter = 0; counter < NumberOfControls; counter++) { DropDownList ddl = new DropDownList(); SqlDataReader dr2 = ADONET_methods.DisplayTableColumns(targettable); ddl.ID = "DropDownListID" + (counter + 1).ToString(); int NumControls = targettable.Length; DataTable dt = new DataTable(); dt.Load(dr2); ddl.DataValueField = "COLUMN_NAME"; ddl.DataTextField = "COLUMN_NAME"; ddl.DataSource = dt; ddl.ID = "DropDownListID 1"; ddl.SelectedIndexChanged += new EventHandler(ddlList_SelectedIndexChanged); ddl.DataBind(); ddl.AutoPostBack = true; ddl.EnableViewState = true; //Preserves View State info on Postbacks //ddlList.Style["position"] = "absolute"; //ddl.Style["top"] = 80 + "px"; //ddl.Style["left"] = 0 + "px"; dr2.Close(); } return ddl; }

  • dynamically create class in scala, should I use interpreter?

    - by Phil
    Hi, I want to create a class at run-time in Scala. For now, just consider a simple case where I want to make the equivalent of a java bean with some attributes, I only know these attributes at run time. How can I create the scala class? I am willing to create from scala source file if there is a way to compile it and load it at run time, I may want to as I sometimes have some complex function I want to add to the class. How can I do it? I worry that the scala interpreter which I read about is sandboxing the interpreted code that it loads so that it won't be available to the general application hosting the interpreter? If this is the case, then I wouldn't be able to use the dynamically loaded scala class. Anyway, the question is, how can I dynamically create a scala class at run time and use it in my application, best case is to load it from a scala source file at run time, something like interpreterSource("file.scala") and its loaded into my current runtime, second best case is some creation by calling methods ie. createClass(...) to create it at runtime. Thanks, Phil

  • OLAP Web Visualization and Reporting Recommendations

    - by Gok Demir
    I am preparing an offer for a customer. They proide weekly data to different organizations. There is huge amount data suits OLAP that needed to be visualized with charts and pivot tables on web and custom reports will be built by non-it persons (an easy gui). They will enter a date range, location which data columns to be included and generate report and optionally export the data to Excel. They currently prepare reports with MS Excel with Pivot Tables and but they need a better online tool now to show data to their customers. Tables are huge and need of drill-down functionality. My current knowledge Spring, Flex, MySql, Linux. I have some knowledge of PostgreSQL and MSSQL and Windows. What is the easiest way of doing this project. Do you think that SSRP (haven't tried yet) and ASP.NET better suits for this kind of job. Actually I prefer open source solutions. Flex have OLAP Data Grid control which do aggregation on client side. JasperServer seems promising but it seems I need enterprise version (multiple organizations and ad hoc queries). What about Modrian + Flex + PostgreSQL solution? Any previous experience will be appreciated. Yes I am confused with options.

  • Applying business logic to form elements in ASP.NET MVC

    - by Brettski
    I am looking for best practices in applying business logic to form elements in an ASP.NET MVC application. I assume the concepts would apply to most MVC patterns. The goal is to have all the business logic stem from the same place. I have a basic form with four elements: Textbox: for entering data Checkbox: for staff approval Checkbox: for client approval Button: for submitting form The textbox and two check boxes are fields in a database accessed using LINQ to SQL. What I want to do is put logic around the check boxes on who can check them and when. True table (little silly but it's an example): when checked || may check Staff || may check Client Staff | Client || Staff | Client || Staff | Client 0 0 || 1 0 0 1 0 1 || 0 0 0 1 1 0 || 1 0 0 1 1 1 || 0 0 0 1 There are to security roles, staff and client; a person's role determines who they are, the roles are maintained in the database alone with current state of the check boxes. So I can simply store the users roll in the view class and enable and disable check boxes based on their role, but this doesn't seem proper. That is putting logic in UI to control of which actions can be taken. How do I get most of this control down into the model? I mean I need to control which check boxes are enabled and then check the results in the model when the form is posted, so it seems the best place for it to originate. I am looking for a good approach to constructing this, something to follow as I build the application. If you know of some great references which explain these best practices that is really appreciated too.

  • adding tabbar to uiview (not tabbarcontroller) to switch views

    - by Pavan
    Hi, i added a Tab bar to my existing view called secondViewController where there are now 4 tab bar items using interface builder. This tab bar will allow the users to switch between views. This is what ive tried to do: If i use a tabbar controller, then a new view pops up and i dont want that. i simply want to be able to add a tab bar as ive done and carry on from there. i dont know how to actually connect it all up and make everything work together. This is what i understand: i have to make my current - secondViewController an tabbardelegate which is what ive done as shown @interface paddedDholViewController : UIViewController <AVAudioPlayerDelegate, UITabBarDelegate> { } then i understand that i have to add tabBar.delegate = self; for me to be able to detect the tabBar:didSelectItem: so i can then implement something like this - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { if ([viewController.tabBarItem.title isEqualToString:@"FIRST"]) { NSLog(@"FIRST"); } else if ([viewController.tabBarItem.title isEqualToString:@"SECOND"]) { NSLog(@"SECOND"); } } to be able to switch between the views The thing is as ive said before i dont know how to implement all of this and how to connect everything up. can someone help me please. Thank you in advance

  • How to produce an HTTP 403-equivalent WCF Message from an IErrorHandler?

    - by Andras Zoltan
    I want to write an IErrorHandler implementation that will handle AuthenticationException instances (a proprietary type), and then in the implementation of ProvideFault provide a traditional Http Response with a status code of 403 as the fault message. So far I have my first best guess wired into a service, but WCF appears to be ignoring the output message completely, even though the error handler is being called. At the moment, the code looks like this: public class AuthWeb403ErrorHandler : IErrorHandler { #region IErrorHandler Members public bool HandleError(Exception error) { return error is AuthenticationException; } public void ProvideFault(Exception error, MessageVersion version, ref Message fault) { //first attempt - just a stab in the dark, really HttpResponseMessageProperty property = new HttpResponseMessageProperty(); property.SuppressEntityBody = true; property.StatusCode = System.Net.HttpStatusCode.Forbidden; property.StatusDescription = "Forbidden"; var m = Message.CreateMessage(version, null); m.Properties[HttpResponseMessageProperty.Name] = property; fault = m; } #endregion } With this in place, I just get the standard WCF html 'The server encountered an error processing the request. See server logs for more details.' - which is what would happen if there was no IErrorHandler. Is this a feature of the behaviours added by WebServiceHost? Or is it because the message I'm building is simply wrong!? I can verify that the event log is indeed not receiving anything. My current test environment is a WebGet method (both XML and Json) hosted in a service that is created with the WebServiceHostFactory, and Asp.Net compatibility switched off. The service method simply throws the exception in question.

  • Android media thumbnails. Serious issues?

    - by Ralphleon
    I've been playing with android's thumbnails for a while now, and I've seen some inconsistencies that make me want to scream. My goal is to have a simple list of all Images (and a separate list for video) with the thumbnail and filename. Device: HTC Evo (fresh from Google I/o) First off: http://androidsamples.blogspot.com/2009/06/how-to-display-thumbnails-of-images.html That code doesn't seem to work at all, thumbnails are duplicated... some with the "mirror" effect and some without. Also some won't load and just display a black square. I've tried rebuilding the thumbnails by deleting the "alblum thumbs" directory from the SD card. HTC's gallery application seem to show everything fine. This approach seems to work: Bitmap thumb = MediaStore.Images.Thumbnails.getThumbnail( getContentResolver(), id, MediaStore.Video.Thumbnails.MICRO_KIND, null); imageView.setImageBitmap(curThumb); where id is the original images id and imageView is some image view. This is great! But, strangely, way too slow to be used inside a SimpleViewBinder. Next approach: String [] proj = {MediaStore.Images.Thumbnails._ID}; Cursor c = managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, proj, MediaStore.Images.Thumbnails.IMAGE_ID + "=" +id , null, null); if (c != null && c.moveToFirst()) { Uri thumb = Uri.withAppendedPath(mThumbUri,c.getLong(0)+""); imageView.setImageURI(thumb); } I should explain that I feel the needed WHERE condition is required because there doesn't seem to be any guarantee that your uri will have the same ID for both a thumbnail and its parent image. This works for all of the current images, but as soon as I start adding pictures with the camera they show up as blank! Debugging shows a dreaded: SkImageDecoder::Factory returned null error and the URI is returned as invalid. These are the same images that work with the previous call. Can anyone either catch my logical failure or point me to some working code?

  • Bazaar + CruiseControl.Net

    - by Chris Gill
    I want to setup CruiseControl.Net at my company. We currently have several .net solutions stored in a Bazaar repository and I want to use MSBuild to build each solution. This didn't seem too controversial, but I can't see an easy way of binding CruiseControl.Net to Bazaar. There seems to have been a plugin to do this at http://www.sorn.net/projects/bazaar-ccnet but this link no longer works and I cant seem to find the plugin anywhere else I was going to use the External source control type, but bazaar seems to bork at the GETMODS parameter being passed to it My current thought now is to create a separate project to pull modifications from bazaar using an Exec task, then create another project to run a FileSystem source control check on that directory. I'm moderately sure I can get this to work, but it seems a bit hacky. I don't mind writing a new Bazaar plugin for CruiseControl.Net but I cant find where to start with this. My questions are do you run these two in combination, if so how do you do it? If you don't run these together, do you have any recommendations on a good approach? Is there any documentation or good starting point that I could use to write a bazaar plugin? Am I an idiot for trying to use CruiseControl.Net? Should I be using something else?

  • Django Admin Page missing CSS

    - by super9
    I saw this question and recommendation from Django Projects here but still can't get this to work. My Django Admin pages are not displaying the CSS at all. This is my current configuration. settings.py ADMIN_MEDIA_PREFIX = '/media/admin/' httpd.conf <VirtualHost *:80> DocumentRoot /home/django/sgel ServerName ec2-***-**-***-***.ap-**********-1.compute.amazonaws.com ErrorLog /home/django/sgel/logs/apache_error.log CustomLog /home/django/sgel/logs/apache_access.log combined WSGIScriptAlias / /home/django/sgel/apache/django.wsgi <Directory /home/django/sgel/media> Order deny,allow Allow from all </Directory> <Directory /home/django/sgel/apache> Order deny,allow Allow from all </Directory> LogLevel warn Alias /media/ /home/django/sgel/media/ </VirtualHost> <VirtualHost *:80> ServerName sgel.com Redirect permanent / http://www.sgel.com/ </VirtualHost> In addition, I also ran the following to create (I think) the symbolic link ln -s /home/djangotest/sgel/media/admin/ /usr/lib/python2.6/site-packages/django/contrib/admin/media/ UPDATE In my httpd.conf file, User django Group django When I run ls -l in my /media directory drwxr-xr-x 2 root root 4096 Apr 4 11:03 admin -rw-r--r-- 1 root root 9 Apr 8 09:02 test.txt Should that root user be django instead?

  • ASP.NET MVC Concurrency with RowVersion in Edit Action

    - by Jorin
    I'm wanting to do a simple edit form for our Issue Tracking app. For simplicity, the HttpGet Edit action looks something like this: // Issues/Edit/12 public ActionResult Edit(int id) { var thisIssue = edmx.Issues.First(i => i.IssueID == id); return View(thisIssue); } and then the HttpPost action looks something like this: [HttpPost] public ActionResult Edit(int id, FormCollection form) { // this is the dumb part where I grab the object before I update it. // concurrency is sidestepped here. var thisIssue = edmx.Issues.Single(c => c.IssueID == id); TryUpdateModel(thisIssue); if (ModelState.IsValid) { edmx.SaveChanges(); TempData["message"] = string.Format("Issue #{0} successfully modified.", id); return RedirectToAction("Index"); } return View(thisIssue); } Which works wonderfully. However, the concurrency check doesn't work because in the Post, I'm re-retreiving the current entity right before I attempt to update it. However, with EF, I don't know how to use the fanciness of SaveChanges() but attach my thisIssue to the context. I tried to call edmx.Issues.Attach(thisIssue) but I get The object cannot be attached because it is already in the object context. An object can only be reattached when it is in an unchanged state. How do I handle concurrency in MVC with EF and/or how do I properly Attach my edited object to the context? Thanks in advance

  • Maintaing JTextArea scroll position

    - by Sami
    I have a JScrollPane with a JTextArea set as its view port. I update the (multi line) text shown on the JTextArea continously about once a second. Each time the text updates, JScrollPane goes all the way to the bottom of the text. Instead, I'd like to figure out the line number that is currently shown as the first line in the original text, and have that line be the first line shown when the text has been updated (or if the new text doesn't have that many lines, then scroll all the way to the bottom). My first attempt of doing this was to get the current caret position, figure the line based on that, and then set the text area to show that line: int currentPos = textArea.getCaretPosition(); int currentLine = 0; try { for(int i = 0; i < textArea.getLineCount(); i++) { if((currentPos >= textArea.getLineStartOffset(i)) && (currentPos < gameStateTextArea.getLineEndOffset(i))) { currentLine = i; break; } } } catch(Exception e) { } textArea.setText(text); int newLine = Math.min(currentLine, textArea.getLineCount()); int newOffset = 0; try { newOffset = textArea.getLineStartOffset(newLine); } catch(Exception e) { } textArea.setCaretPosition(newOffset); This was almost acceptable for my needs, but requires the user to click inside the text area to change the caret position, so that the scrolling will maintain state (which isn't nice). How would I do this using the (vertical) scroll position instead ?

  • jQuery not and classes

    - by Giles B
    Hi Guys, I have 2 anchor links (a.selector) and when one is clicked it has a class applied to it of 'active-arrow' and the click also removes the class of the same name from the other anchor as well as lowering the opacity to 0.2. I then want to have a fade effect when the user hovers over the anchor that doesn't have 'active-arrow' applied to it so that it goes to full opacity when mouseenters and back to 0.2 when mouseleaves. The problem im having is that both .not and :not don't seem to be working as expected, the hover effect works but if I click on the anchor whilst hovering the 'active-arrow' class is applied but when mouseleaves the opacity is faded down to 0.2 again even though the 'active-arrow' class is applied. Also the hover then doesn't work for the other a link which has had 'active-arrow' removed. Bit of a hard one to explain so heres some code that hopefully helps a bit. *//If a.selector doesn't have the class 'active-arrow' then run the hoverFade function* $("a.selector").not(".active-arrow").hoverFade(); //Functions for first element $('a.selector-1').click(function () { $('a.selector-2').removeClass('active-arrow'); //Remove background image from corresponding element $('ul#storage-items-2').fadeOut(1200).addClass('hide'); //Fade out then hide corresponding list $(this).addClass('active-arrow', 'fast'); //Add background image to current element $('ul#storage-items-1').removeClass('hide').fadeIn(1800); //Unhide and fade in the list $('a.selector-2').fadeTo(500, 0.2); //Fade corresponding element $(this).fadeTo(800, 1);//Fade this element to full opacity }); I only included the code for teh first anchor (a.selector-1) as the code for the second anchor is identical but just changes the class names to a.selector-2. Also the hoverFade function is in a seperate file so we can re-use it. jQuery.fn.hoverFade = function() { return this.each(function(){ $(this).hover( function () { $(this).fadeTo(500, 0.8); }, function () { $(this).fadeTo(500, 0.2); }); }); } Each anchor link fades in and fades out a UL as well. Any help is most appreciated Thanks Giles

  • How can I implement NHibernate session per request without a dependency on NHibernate?

    - by Ben
    I've raised this question before but am still struggling to find an example that I can get my head around (please don't just tell me to look at the S#arp Architecture project without at least some directions). So far I have achieved near persistance ignorance in my web project. My repository classes (in my data project) take an ISession in the constructor: public class ProductRepository : IProductRepository { private ISession _session; public ProductRepository(ISession session) { _session = session; } In my global.asax I expose the current session and am creating and disposing session on beginrequest and endrequest (this is where I have the dependency on NHibernate): public static ISessionFactory SessionFactory = CreateSessionFactory(); private static ISessionFactory CreateSessionFactory() { return new Configuration() .Configure() .BuildSessionFactory(); } protected MvcApplication() { BeginRequest += delegate { CurrentSessionContext.Bind(SessionFactory.OpenSession()); }; EndRequest += delegate { CurrentSessionContext.Unbind(SessionFactory).Dispose(); }; } And finally my StructureMap registry: public AppRegistry() { For<ISession>().TheDefault .Is.ConstructedBy(x => MvcApplication.SessionFactory.GetCurrentSession()); For<IProductRepository>().Use<ProductRepository>(); } It would seem I need my own generic implementations of ISession and ISessionFactory that I can use in my web project and inject into my repositories? I'm a little stuck so any help would be appreciated. Thanks, Ben

  • Relative path from an ASP.NET user control NavigateUrl

    - by Daniel Ballinger
    I have a user control that contains a GridView. The GridView has both a HyperLinkField column and a template column that contains a HyperLink control. The ASP.NET project is structured as follows, with the Default.aspx page in each case using the user control. Application Root Controls UserControl with GridView SystemAdminFolder Default.aspx Edit.aspx OrganisationAdminFolder Default.aspx Edit.aspx StandardUserFolder Default.aspx Edit.aspx Note: The folders are being used to ensure the user has the correct role. I need to be able to set the DataNavigateUrlFormatString for the HyperLinkField and the NavigateUrl for the HyperLink to resolve to the Edit.aspx page in the corresponding folder. If I set the navigate URL to "Edit.aspx" the URL in the browser appears as 'http://Application Root/Controls/Edit.aspx' regardless of the originating directory. I can't use the Web application root operator (~/) as the path needs to be relative to the current page, not the application root. How can I use the same user control in multiple folders and resolve the URL to another page in the same folder? Note: The question is strongly based off a similar question by azhar2000s on the asp.net forums that matches my problem.

  • WPF TabBarControl Setting Focus to element when tab changes

  • MEF = may experience frustration?

    - by Dave
    Well, it's not THAT bad yet. :) But I do have questions after Reed has pointed me at MEF as a potential alternative to IoC (and so far it does look pretty good). Consider the following model: As you can see, I have an App, and this app uses Plugins (whoops, missed that association!). Both the App and Plugins require usage of an object of type CandySettings, which is found in yet another assembly. I first tried to use the ComposeParts method in MEF, but the only way I could get this to work was to do something like this in the plugin code. var container = new CompositionContainer(); container.ComposeParts(this, new CandySettings()); But this doesn't make any sense, because why would I want to create the instance of CandySettings in the plugin? It should be in the App. But if I put it in the App code, then the Plugin doesn't magically figure out how to get at ICandySettings, even though I am using [Import] in the plugin, and [Export] in CandySettings. The way I did it was to use MEF's DirectoryCatalog, because this allows the plugin, when constructed, to scan all of the assemblies in the current folder and automagically import everything that is marked with the [Import] attribute. So it looks like this, and potentially in every plugin: var catalog = new DirectoryCatalog( "."); var container = new CompositionContainer( catalog); container.ComposeParts( this); This totally works great, but I can't help but think that this is not how MEF was intended to be used?

  • Double split in C

    - by Dmitri
    Hi again dear community! OK. For example I have this line in my txt file: 1|1,12;7,19;6,4;8,19;2,2 . As you can see, it has 2 parts, separated by "|". I have no problems getting both parts, and separating second part ( 1,12;7,19;6,4;8,19;2,2 ) using ";" separator. BUT I do have problems with separating further by "," to get first and second number of each set. This is my current code: result = strtok(result, ";"); while(result != NULL ) { printf("%s\n", result); result = strtok(NULL, ";"); } It outputs me: 1,12 7,19 6,4 8,19 2,2 OK, great. But when I try to 'strtok' (I'm using this method for splitting) like this: result = strtok(result, ";"); while(result != NULL ) { //printf("%s\n", result); help = strtok(result, ","); while(help != NULL) { printf("<%s>", help); help = strtok(NULL, ","); } result = strtok(NULL, ";"); } I only get "<1,<12" like there is only one set in this set of numbers. I dont understand where are the rest of the numbers. Instead, output should be: <1,<12,<7,<19,<6,<4,<8,<19,<2,<2. Could someone please give a solution, how to get EACH number of each set this set of numbers. Maybe there are other methods or I'm doing something wrong :) Thank you! Best Regards, Dmitri

  • No long-running conversations - IllegalArgumentException: Stack must not be null

    - by Markos Fragkakis
    Hi all, I have a very simple application with just 2 pages on WebLogic 10.3.2 (11g), Seam 2.2.0.GA. I have a command button in each, which makes a redirect-after-post to the other. This works well, as I see the URL of the current page I am seeing in the address bar. BUT, even though I have no long-running conversations defined, after a random number of clicks, and - I think - after a random number of seconds (~10s - 60s) I get the lovely exception at the end of this post. Now, if I have understood how temporary conversations work when redirecting this happens: When I first see my application, the url is http://localhost:7001/myapp When I click the button in pageA.xhtml, I end up in "pageB.xhtml?cid=26". This is normal because Seam extends the temporary conversation of the first request to last until the renderResponse phase of the redirect. So, it uses the cid (Conversation Id) of the extended temporary conversation to find any propagated parameters. When I click the button in pageB.xhtml, I end up in pageA.xhtml?cid=26 The same cid was given to the new extended temporary conversation. This is normal because the conversation ended at the end of the previous redirect-after-post, and not the number 26 is free to use as a cid. Is this all correct? If yes, why does this happen: If I re-type the applications home address (showing pageA) and re-click, I end up in pageB.xhtml?cid=29, which is a different number than 26. But 26 has ended after the previous RenderResponse phase, befire I re-types the url. Why is it not used instead of 29? So, to sup up, 2 questions: Why do I get the exception, even though I have not started any long-running conversations? What happens exactly with the cid? On what basis does it change? Cheers,

  • ClickOnce permissions

    - by stephenfalken
    We recently updated our main website. This included creating a new directory to hold the new site; then, some of the existing subdirectories needed to be copied over. Some of the virtual directories below the main site are clickonce publishing locations. These have been 100% successful publishing locations for 3 years now. We would update the application in Visual Studio and then publish... painless. Very long story short, since we've copied the directories to the new main site location on disk, all of our clickonce sites except one will no longer publish. They all fail with an error saying "you are not authorized to perform the current operation". This is immeidately after we set permissions to Full Control for my domain user group. I've checked everything I know how to check as far as permissions go and made the non-working ones' permissions match the one that does work, but no joy. We had problems on Friday and I fixed the one site that does work, but I can't remember how I fixed it; all I remember is that it took a long time screwing with it to make it work. Could there be some arcane setting in IIS that has been omitted? Is there a simple list of things to check anywhere on the Net? ClickOnce information is scattered among 50,000 URLs and I haven't been able to figure it out again. Thanks

  • 500 error using lighttpd, fastcgi and PHP on file upload

    - by Dan
    I have a server running lighttpd with fastcgi, and it appears to be working correctly. However when I try to upload a file using a form, I get a 500 Internal server error, along with the following in the logs: 2012-03-23 18:25:09: (mod_fastcgi.c.2566) unexpected end-of-file (perhaps the fastcgi process died): pid: 2755 socket: unix:/tmp/php-fastcgi-1.socket-0 2012-03-23 18:25:09: (mod_fastcgi.c.3354) response not received, request sent: 50437 on socket: unix:/tmp/php-fastcgi-1.socket-0 for /index.php?url=brand/manager, closing connection I've been looking around for a long while now trying to find a solution to the issue, but nothing I'm trying is working. My current fastcgi conf looks as follows: server.modules += ( "mod_fastcgi" ) fastcgi.server = ( ".php" => (( "socket" => "/tmp/php-fastcgi-1.socket", "bin-path" => "/usr/bin/php-cgi", "allow-x-send-file" => "enable", "max-procs" => 1, "broken-scriptfilename" => "enable" )) ) If anyone could suggest if there is anything wrong in the configuration it would be greatly appreciated, or any suggestion as to what I might do? As I say, it is only happening when trying to upload a file (the file in question being only 45k). Thanks, Dan
