• PrimeFaces commandButton doesn't navigate or update

  - by Sven

  I'am using Primefaces to make my app a little bit more beautiful. I noticed that p:commandButton and h:commandButton don't work the same way. The p:commandButton calls the method and nothing else hapens. The h:commandButton calls the method and returns a navigation. I have got trouble with redirecting after pressing the login button when using p:commandButton. How to deal with that? I do have an update parameter: <p:commandButton value="Login" action="#{login.login}" type="submit" update="msgs" />

• Grails remoteLink handling error codes

  - by soybie

  I'm on grails 1.3.6 and I see the following behavior. <g:javascript library="prototype" /> ... <g:remoteLink action="punch" id="${personInstance.id}" update="damage_${personInstance.id}" on401="alert('foo!');"> generates: <a on401="alert('foo!');" onclick="new Ajax.Updater('damage_5','/blah/person/punch/5',{asynchronous:true,evalScripts:true});return false;" href="/blah/person/punch/5"></a> "on401" isn't a supported event attribute for an anchor tag, so is this a bug in grails?

• Rails: include related object in JSON output

  - by Codezy

  I have a note class that belongs to a user (ie a user can create many notes). clip from my notes controller class NotesController < ApplicationController before_filter :authenticate_user! respond_to :html, :xml, :json # GET /notes # GET /notes.xml def index @notes = Note.includes(:user).order("created_at DESC") respond_with @notes end When I ask for the index in json results for example /notes.json, it returns the notes but only returns user_id for the user object. I would like it to also include user.username (and would be curious how to have the whole user object embedded). Bonus question: I could not find a way to make the column show as author_id and have it relate back to user. If this is easy to do, how do you do it?

• Urls parameters doesn't encoding correctly!

  - by Ivan90

  I'am using asp.net mvc version 1.0 and I've a problem with some parameter in a url! My url is look like so(http://localhost:2282/Tags/PostList/c#) routes.MapRoute( "TagsRoute", "Tags/PostList/{tag}", new { controller="Tags",Action="PostList",tag = "" } ); In effect the problem is that tag paramter isn't encoding and so simbol # is ignored! I am using an actionlink but maybe with version 1.0 isn't encoding parameter directly! <%=Html.ActionLink(itemtags.Tags.TagName, "PostList","Tags", new { tag = itemtags.Tags.TagName }, new { style = "color:red;" })%> With this actionlink only whitespace are encoding correctly, infact asp.net mvc become asp.net%20mvc and it work fine! But c# isn't encoding :( So I try to use Server.UrlEncode, and in effect it happen some stuff!!! Infact c# became c%2523 but it isn't correct again because hexadecimal of # is %23! Have you some solutions???? Route Contraints? Thanks

• ASP MVC C#: Is it possible to pass dynamic values into an attribute?

  - by wh0emPah

  Okay I'm very new to C# and i'm trying to create a little website using ASP MVC2. I want to create my own authorization attribute. but i need to pass some values if this is possible. For example: [CustomAuthorize(GroupID = Method Parameter?] public ActionResult DoSomething(int GroupID) { return View(""); } I want to authorize the access to a page. but it depends on the value passed to the controller. So the authorization depends on the groupID. Is this possible to achieve this in any way?. Thanks in advance.

• Do I need to invoke MessageBox calls?

  - by mafutrct

  To pop-up a message box, I'm using MessageBox.Show(...). I usually wrap this call in an Invoke: BeginInvoke (new Action (() => { MessageBox.Show ()); })); I've got 2 questions: Do I always need to wrap the MessageBox call in an Invoke if I'm calling from a non-GUI thread? If so, should I use BeginInvoke or Invoke? I found not much difference in my tests, BeginInvoke is, as expected (and unlike Invoke), displayed with a slight delay.

• Where can I find soft-multiply and divide algorithms?

  - by srking

  I'm working on a micro-controller without hardware multiply and divide. I need to cook up software algorithms for these basic operations that are a nice balance of compact size and efficiency. My C compiler port will employ these algos, not the the C developers themselves. My google-fu is so far turning up mostly noise on this topic. Can anyone point me to something informative? I can use add/sub and shift instructions. Table lookup based algos might also work for me, but I'm a bit worried about cramming so much into the compiler's back-end...um, so to speak. Thanks!

• How to make one ASP.NET MVC site "derive" from another.

  - by Rob Levine

  My question is similar to "ASP.NET 2 projects to share same files", but with an ASP.NET MVC slant. Basically, we have two sites, one being based mostly on the other (roughly 90% views, controllers, images, in the second are identical to the first). However, in some cases, the views may be different, or a controller in the second site may be different to the first. Are there any simple ways of achieving this in ASP.NET MVC? So far, we've looked at using linked files to have two totally seperate projects where the second project shares the files it needs from the first. One problem with this approach is that most pages in the second project don't literally exist in the virtual directory, it makes debugging a pain - you have to publish in order to generate the files so you can debug. Does anyone have any better approaches, or ways this approach can be simplified?

• Paperclip + ImageMagick on Windows 7: Image display fails when I add styles to attached_file in mode

  - by Brian Roisentul

  I'm working with Ruby on rails 2.3.8, NetBeans IDE. I've installed paperclip and I could show/save images successfully. Now, I've installed ImageMagick-6.6.2-4-Q16(for windows 7, 64bits). Until that moment, my model looked like this(and worked fine): has_attached_file :photo Now, after installing ImageMagick, when I add the :style line it fails: has_attached_file :photo, :styles => {:thumb => "100x100#", :small => "150x150>", :large => "400x400>" } and it throws the following error message when I try to upload an image: TypeError in ProfilesController#update backtrace must be Array of String The only thing I'm doing in the update action of that controller is the following: @profile.update_attributes(params[:profile]) @profile.update_attribute(:photo, params[:profile][:photo]) I've also installed miniMagick gem(because I read somewhere I had to do it). What am I missing?

• MCV/MVP Patterns and Applications that interface with Hardware (DAQ/PLC/etc)

  - by Ryan

  I've been reading a lot about the MCV and MVP patterns for use with UI and it seems like a really nice powerful way to handle user interfaces. I am - however - having a difficult time deciding how this could integrate into a system where data in the model is created from a Data Acquisition System or Serial/Ethernet devices. There is also the added step that 70% of application interaction is performed by a PLC instead of a live user. It seems that for apps that just read/write & manipulate information from a database this works great, but how does does hardware and automation fit into these patterns? Is it as simple as another controller (for lack of a better term) that interacts with hardware that manipulates data and writes to a model? Maybe I am over thinking this or thinking too simply, so any advice would be great. I'm not quite sure where I'm going with this, so if something doesn't make sense or I was too vague leave me a comment. Thanks!

• POST from a submit button in C#

  - by Marlon

  I'm not familiar with http stuff, but how would I be able to submit data to a website? There is a submit button that I would like to "press" from a console app. This is not my own website. This is part of the page source, not sure if it has any relevance: <form action="rate.php" method="post"> I looked at the HttpWebRequest class but I am unfamiliar with what properties I need to fill in. Sorry I'm so vague but I'm not familiar with http.

• CodeIgniter Validation in Library does not accept callback.

  - by Lukas Oppermann

  Hey guys, my problem is the following: I am writing a login library. This library has a function _validation() and this uses the validation library to validate the data. With using normal validation methods it works just fine, but using a callback function just does not work. It is not called. I call it like this. $this->CI->form_validation->set_rules('user', 'Username', 'required|callback__check_user'); The functions name is _check_user and it uses the username _check_user($user). The function itself works fine and I can also call it in the class ($this-_check_user('username')) with a working result. I am guessing, there might be a problem because I am not workin in a controller so I have a CI instance $this-CI instead of just the original instance $this- Does anyone have a clue how to fix this? Thanks in advance.

• Code is exectuting but the view is not loading when called form a function?

  - by wolverine

  I have a viewBased application with the viewController class mainView. In it I am loading various views(different nibs) depending upon certain actions that I do. I have added a popoverController with a barbutton in the mainView. Its intialized with a tableviewController class named popClass. When I select certain row in the popover, I want the view in my mainView to load someother view(as I do when i do certain actions). For that I have written a function in mainView Controller class and is calling it from the popOver class. Function and the lines of code are executing but nothing is happening. Even the log lines are printed but no action takes place. What is the problem? OR is there anyother way to make the view change in mainView by using the popover?

• JSON Object XHR and closures

  - by Sara Chipps

  Hi all, I have a JSON object that is populated by an XHR. I then need to update that object with values from a separate XHR call. The issue I am running into is the second call isn't being made at the correct time and I think it's an issue with how I structured my object. Here is what I have: function Proprietary() { var proprietary= this; this.Groups = {}; this.getGroups = function() { $.getJSON(group_url, function(data){proprietary.callReturned(data);}); } this.callReturned = function(data) { //Do stuff for(var i=0; i< data.groups.length; i++) { insparq.Groups[i] = data.groups[i]; $.getJSON(participant_url, function(p){proprietary.Groups[i].participants = p;}); } //the function call below is the action I want to occur after the object is populated. PopulateGroups(); } };

• UIViewController is popped from view stack and NSURLConnection crashes the application

  - by rickharrison

  I am pushing a UIViewController onto a UINavigationController. This view controller immediately starts a download of an xml feed and then parses it. However, if you hit the back button before it is done downloading, and crashes with EXC_BAD_ACCESS. The line that is crashing it is in parserDidEndDocument and is this line: if (self.delegate && [self.delegate conformsToProtocol:@protocol(ModelDelegate)]) [self.delegate modelDidFinishParsing:self]; I assume it is crashing because it is trying to access self.delegate which is not assigned anymore. How do I get around this? Also, I would release the model object in the modelDidFinishParsing method. How would I release this model if it never reaches this method.

• Why Eclipse does not see .jar file of a library?

  - by Roman

  I have a java project in which I have "Referenced Libraries". In the "Referenced Libraries" I have a .jar file of a library that I use (I use only one external library). When I try to "Run - Run" the code I have a NullPointerException. From my previous experience I know that it it (very likely) because my code does not see the library. I just started to use Eclipse and it can be the I do not "connect" libraries in a correct way. Should I use some options or additional action to force Eclipse to see the .jar file of the library? ADDED: By the right click on the library I get a drop-down menu in which I see "Build Path". My be I need to do something there?

• Installing CodeIgniter on root and WordPress in sub-directory

  Hello, I want to create a website where the main pages will be served from CodeIgniter. I will use Wordpress in the /blog/ sub-directory to host the blog. Thats it! I want nothing else. Just to make sure that: example.com/somepage/ calls a CI controller where as example.com/blog/some-post/ is handled by Wordpress. I don't need any kind of integration or interaction between CI and WP. Is it possible to install in that way? If not, any workarounds so that I can achieve the objectives? Thanks and Regards, Masnun

• ActionController::InvalidAuthenticityToken: verified with authentication token on the form!

  - by goodwill

  I don't know why it happens but my form for some reason does not post properly. I am very sure the form contains the required authentication token: <form action="/account/complete_verify_email/4df78710-e27b-4527-bd2d-71cd2e9a1271" method="post"><div style="margin:0;padding:0"><input name="authenticity_token" type="hidden" value="341b07dfa682ed11a045e19956e2e3f5f499e8cb"></div> <input id="password" name="password" type="password"> <input name="commit" type="submit" value="Continue"> </form> Note the authenticity_token is there. What happened? And YOU KNOW WHAT? Quitting Safari and restart again solved the issue... but I can't think of what kind of intermittent behaviour could cause such problem.
