  • Show NSSegmentedControl menu when segment clicked, despite having set action

    - by Justin Williams
    I have an NSSegmentedControl on my UI with 4 buttons. The control is connected to a method that will call different methods depending on which segment is clicked: - (IBAction)performActionFromClick:(id)sender { NSInteger selectedSegment = [sender selectedSegment]; NSInteger clickedSegmentTag = [[sender cell] tagForSegment:selectedSegment]; switch (clickedSegmentTag) { case 0: [self showNewEventWindow:nil]; break; case 1: [self showNewTaskWindow:nil]; break; case 2: [self toggleTaskSplitView:nil]; break; case 3: [self showGearMenu]; break; } } Segment 4 has has a menu attached to it in the awakeFromNib method. I'd like this menu to drop down when the user clicks the segment. At this point, it only will drop if the user clicks & holds down on the menu. From my research online this is because of the connected action. I'm presently working around it by using some code to get the origin point of the segment control and popping up the context menu using NSMenu's popUpContextMenu:withEvent:forView but this is pretty hacktastic and looks bad compared to the standard behavior of having the menu drop down below the segmented control cell. Is there a way I can have the menu drop down as it should after a single click rather than doing the hacky context menu thing?

  • MUD (game) design concept question about timed events.

    - by mudder
    I'm trying my hand at building a MUD (multiplayer interactive-fiction game) I'm in the design/conceptualizing phase and I've run into a problem that I can't come up with a solution for. I'm hoping some more experienced programmers will have some advice. Here's the problem as best I can explain it. When the player decides to perform an action he sends a command to the server. the server then processes the command, determines whether or not the action can be performed, and either does it or responds with a reason as to why it could not be done. One reason that an action might fail is that the player is busy doing something else. For instance, if a player is mid-fight and has just swung a massive broadsword, it might take 3 seconds before he can repeat this action. If the player attempts to swing again to soon, the game will respond indicating that he must wait x seconds before doing that. Now, this I can probably design without much trouble. The problem I'm having is how I can replicate this behavior from AI creatures. All of the events that are being performed by the server ON ITS OWN, aka not as an immediate reaction to something a player has done, will have to be time sensitive. Some evil monster has cast a spell on you but must wait 30 seconds before doing it again... I think I'll probably be adding all these events to some kind of event queue, but how can I make that event queue time sensitive?

  • Which pdf elements could cause crashes?

    - by Felixyz
    This is a very general question but it's based on a specific problem. I've created a pdf reader app for the iPad and it works fine except for certain pdf pages which always crash the app. We now found out that the very same pages cause Safari to crash as well, so as I had started to suspect the problem is somewhere in Apple's pdf rendering code. From what I have been able to see, the crashing pages cause the rendering libraries to start allocating memory like mad until the app is killed. I have nothing else to help me pinpoint what triggers this process. It doesn't necessarily happen with the largest documents, or the ones with the most shapes. In fact, we haven't found any parameter that helps us predict which pages will crash and which not. Now we just discovered that running the pages through a consumer program that lets you merge docs gets rid of the problem, but I haven't been able to detect which attribute or element it is that is the key. Changing documents by hand is also not an option for us in the long run. We need to run an automated process on our server. I'm hoping someone with deeper knowledge about the pdf file format would be able to point me in a reasonable direction to look for document features that could cause this kind of behavior. All I've found so far is something about JBIG2 images, and I don't think we have any of those.

  • Packet fragmentation when sending data via SSLStream

    - by Ive
    When using an SSLStream to send a 'large' chunk of data (1 meg) to a (already authenticated) client, the packet fragmentation / dissasembly I'm seeing is FAR greater than when using a normal NetworkStream. Using an async read on the client (i.e. BeginRead()), the ReadCallback is repeatedly called with exactly the same size chunk of data up until the final packet (the remainder of the data). With the data I'm sending (it's a zip file), the segments happen to be 16363 bytes long. Note: My receive buffer is much bigger than this and changing it's size has no effect I understand that SSL encrypts data in chunks no bigger than 18Kb, but since SSL sits on top of TCP, I wouldn't think that the number of SSL chunks would have any relevance to the TCP packet fragmentation? Essentially, the data is taking about 20 times longer to be fully read by the client than with a standard NetworkStream (both on localhost!) What am I missing? EDIT: I'm beginning to suspect that the receive (or send) buffer size of an SSLStream is limited. Even if I use synchronous reads (i.e. SSLStream.Read()), no more data ever becomes available, regardless of how long I wait before attempting to read. This would be the same behavior as if I were to limit the receive buffer to 16363 bytes. Setting the Underlying NetworkStream's SendBufferSize (on the server), and ReceiveBufferSize (on the client) has no effect.

  • Making a table in a scrolling div resizable?

    - by Mason Jones
    I've got a table in a div, with a vertical scrollbar on the div to allow the table to be longer than the div can hold. Works fine. But I'd like to allow the user to resize the div vertically if they want to be able to view more of the table. I've been playing with the jQueryUI resizable interaction, but it doesn't seem to quite do what I want; at least, not so far. I've tried making the wrapper div resizable, but the behavior's erratic. If I have the style "height:20em; overflow:auto;" on it, then I can resize the table horizontally, but not vertically. If I remove the overflow, then the table flows outside the div of course. If I remove the height, then the table is actually resizable, but it is initially drawn at full height. Anyone know of a way to specify an initial height, but allow it to be resized larger than that? If I make the table resizable rather than the div, then I can resize the table horizontally within the div but I can't increase the height of the displayed table. Which makes sense, of course, but I thought I'd mention it. Also, is there a way to make the resize "handle" the corner between the horizontal and vertical scrollbars? Right now it's a sort of invisible handle in the bottom-right of the table. Thanks for any thoughts.

  • JQuery checkbox state is updated differently between group click() and $.each(obj.click())

    - by teerapap
    The code below doesn't work in the same behavior. The sequence of click event and calling foo() is different. I want to know why they behave different sequence between call click() and iterate the objects before call click() on each. <script type="text/javascript"> function foo(obj){ alert(obj.id+" ->"+obj.checked); } function clickAll(val){ if (val) { $(":checkbox").click(); } else { $(":checkbox").each(function(i,obj){ obj.click(); }); } } </script> </head> <body> <input type="checkbox" id="check1" onclick="foo(this)" /> a <input type="checkbox" id="check2" onclick="foo(this)" /> b <input type="checkbox" id="check3" onclick="foo(this)" /> c <input type="button" onclick="clickAll(true)" value="click all" /> <input type="button" onclick="clickAll(false)" value="click all each" /> </body>

  • Weird output of Throwable getMessage()

    - by Ravi Gupta
    Hi I have below pseudo code with throws an exception like this throw new MyException("Bad thing happened","com.stuff.errorCode"); where MyException extends Exception class. So the problem is when I try to get the message from MyException class by calling myEx.getMessage() it returns ???en_US.Bad thing happened??? instead of my original message i.e. Bad thing happened I have checked that MyException class doesn't overrides Throwable class's getMessage() behavior. Below is the how the call passes from MyException.getMessage() to Throwable.getMessage() public MyException(String msg, String sErrorCode){ super(msg); this.sErrorCode = sErrorCode; this.iSeverity = 0; } which then calls public Exception(String message) { super(message); } and finally public Throwable(String message) { fillInStackTrace(); detailMessage = message; } when I do a getMessage on myexception it calls Throwable's getMessage as below public String getMessage() { return detailMessage; } So ideally it should return the original message as I set when throwing the exception. What's the ???en_US thing ?

  • How to update child iFrame's entire html (header+body) inside jQuery's post

    - by knappy
    I have a chat webpage for Firefox that is structured like this ..... Outer HTML -----|......Frameset Frame ------------|...... header: contains jQuery post has returned data: rdata = new_iFrame_html_str, the entire html string of the iFrame that should be updated ------------|...... iFrame --------------------|...... header: contains jQuery --------------------|...... body: chat messages that depends on the header jQuery to behave properly QUESTION: I can't this jQuery post to work, i.e. I can't find a way for this post to update the ENTIRE iFrame (header + body). Things I've tried and FAILED with javascript and jQuery: top.frames['framesetFrame_name'].document.getElementById('iframe_id').contentDocument.body.innerHTML = new_iFrame_html_str; I don't like this because it's only changing the body, not the header, so the behavior generated from jQuery can't be shown top.frames['framesetFrame_name'].document.getElementById('iframe_bucinid').contentWindow.location.reload(); I do not want to reload because a reload makes the iFrame flicker, bad for a chat program top.frames['framesetFrame_name'].document.getElementById('iframe_id').contents().html = new_iFrame_html_str; Not updating anything that shows :( top.frames['framesetFrame_name'].document.getElementById('iframe_id').contentWindow.location.href = new_iFrame_html_str; This is actually the wrong form here, because it should be = url_of_new_content $( top.frames['framesetFrame_name'].document.getElementById('iframe_id') ).html( new_iFrame_html_str ) ; Not updating anything that shows :(

  • Handling Application Logic in Multiple AsyncTask onPostExecute()s

    - by stormin986
    I have three simultaneous instances of an AsyncTask for download three files. When two particular ones finish, at the end of onPostExecute() I check a flag set by each, and if both are true, I call startActivity() for the next Activity. I am currently seeing the activity called twice, or something that resembles this type of behavior. Since the screen does that 'swipe left' kind of transition to the next activity, it sometimes does it twice (and when I hit back, it goes back to the same activity). It's obvious two versions of the activity that SHOULD only get called once are being put on the Activity stack. The only way I can find that this is possible is if both AsyncTasks' onPostExecute() executed SO simultaneously that they were virtually running the same lines at the same time, since I set the 'itemXdownloaded' flag to true right before I check for both and call startActivity(). But this is happening enough that it's very hard for me to believe that both downloads are finishing precisely at the same time and having their onPostExecute()s so close together... Any thoughts on what could be going on here? General gist of code (details removed, ignore any syntactical errors I may have edited in): // In onPostExecute() switch (downloadID) { case DL1: dl1complete = true; break; case DL2: dl2complete = true; break; case DL3: dl3complete = true; break; } // If 1 and 2 are done, move on (DL3 still going in background) if ( downloadID != DL3 && dl1complete && dl2complete) { ParentClass.this.startActivity(new Intent(ParentClass.this, NextActivity.class)); }

  • JDialog setResizable(false) is not working in Window Title Bar Menu

    - by jolonaleur
    JDialog setResizable(false) is not working in Window Title Bar Menu Windows XP SP2 Java JRE 1.6.0_11-b03 Behavior varies. Sometimes, the Maximize and Minimize item on the window menu is disabled and sometimes enabled. Steps to reproduce enabled Maximize and Minimize button: Show the JDialog with setResizable(false) Open another window, say for example Notepad. Right-click on the window title bar of Notepad and click Maximize. Go to your JDialog and right click on the window title bar. Maximize window is enabled. Likewise, to disable the Maximize item for the JDialog, go to the maximized Notepad window and right click on title bar. Maximize item is disabled in the Notepad window. Go the your JDialog and right click on the title bar, notice that the Maximize item is also disabled. Note that my application can not use the defaultLookAndFeel method of java dialogs. The bug report related to this was for Solaris OS but that was already ages ago. bug report Is there any workaround? Thanks.

  • Zend Partial + Zend Action Helper causes an additional request to bootstrap?

    - by AndreLiem
    I've been profiling some zend framework code with webgrind to see where some bottle necks are and I'm noticing some very odd behavior. Using the zend partial for example, if I pass a variable value that comes from a zend action helper, it results in two requests being made. in sample.phtml echo $this->partial('partial/embed.phtml', array('url' => $this->url)); in indexcontroller.php $this->view->url = $this->_helper->Embed()->url; But if I don't pass the value from the helper to the partial, but still run the helper, it only makes one request in webgrind. e.g. $this->view->url = 'test'; $this->_helper->Embed()->url; Does anybody know why this could be happening? Am I potentially interpreting web grind incorrectly, or is it really calling the bootstrap twice when the an action helper value is tied to a partial? I'm starting to realize how inefficient some components of Zend are. Thanks

  • SQL Server problems reading columns with a foreign key

    - by illdev
    I have a weird situation, where simple queries seem to never finish for instance SELECT top 100 ArticleID FROM Article WHERE ProductGroupID=379114 returns immediately SELECT top 1000 ArticleID FROM Article WHERE ProductGroupID=379114 never returns SELECT ArticleID FROM Article WHERE ProductGroupID=379114 never returns SELECT top 1000 ArticleID FROM Article returns immediately By 'returning' I mean 'in query analyzer the green check mark appears and it says "Query executed successfully"'. I sometimes get the rows painted to the grid in qa, but still the query goes on waiting for my client to time out - 'sometimes': SELECT ProductGroupID AS Product23_1_, ArticleID AS ArticleID1_, ArticleID AS ArticleID18_0_, Inventory_Name AS Inventory3_18_0_, Inventory_UnitOfMeasure AS Inventory4_18_0_, BusinessKey AS Business5_18_0_, Name AS Name18_0_, ServesPeople AS ServesPe7_18_0_, InStock AS InStock18_0_, Description AS Descript9_18_0_, Description2 AS Descrip10_18_0_, TechnicalData AS Technic11_18_0_, IsDiscontinued AS IsDisco12_18_0_, Release AS Release18_0_, Classifications AS Classif14_18_0_, DistributorName AS Distrib15_18_0_, DistributorProductCode AS Distrib16_18_0_, Options AS Options18_0_, IsPromoted AS IsPromoted18_0_, IsBulkyFreight AS IsBulky19_18_0_, IsBackOrderOnly AS IsBackO20_18_0_, Price AS Price18_0_, Weight AS Weight18_0_, ProductGroupID AS Product23_18_0_, ConversationID AS Convers24_18_0_, DistributorID AS Distrib25_18_0_, type AS Type18_0_ FROM Article AS articles0_ WHERE (IsDiscontinued = '0') AND (ProductGroupID = 379121) shows this behavior. I have no idea what is going on.

Anyone can tell me how to handle such a situation? More info, anyone? Additional Info: this does not seem to be restricted to this Foreign Key, but all/some referencing this entity.

  • Spring bean initialization in a web app

    - by EugeneP
    We work with a web application and autowire beans using WebApplicationContextUtils in the init method. Could you clarify some details about bean initialization? The question rises from the static factory method. Suppose there's a bean that is created in a static factory method. As we can see, when the web app is deployed, the ContextLoaderListener initializes all the beans present in Spring xml config file. Now happens such a thing. In the static factory method we run a timer that starts ticking. But in reality we wouldn't want it to start ticking unless the bean is injected into a property of the object ! That is question number one - all the beans are automatically initialized on deploy - correct? And after that when we need an injection, it simply feels the link with the address of the object created during initialization, though OBJECT WAS CREATED ON WEB APP DEPLOY, immediately ! (I assume the default singleton-creation Spring behavior) Second question: are all copies of a web app use the same beans, so all beans are WEB-APP wide, every Spring bean is shared between all the copies of this web app running?

  • URLLoader.load() issue when using the same URLRequest

    - by Rudy
    Hello, I have an issue with my eventListeners with the URLLoader, but this issue happens in IE, not in FF. public function getUploadURL():void { var request:URLRequest = new URLRequest(); request.url = getPath(); request.method = URLRequestMethod.GET; _loader = new URLLoader(); _loader.dataFormat = URLLoaderDataFormat.TEXT; _loader.addEventListener(Event.COMPLETE, getBaseURL); _loader.load(request); } private function getBaseURL(event:Event):void { _loader.removeEventListener(Event.COMPLETE, getBaseURL); } The issue is that my getBaseURL gets executed automatically after I have executed the code at least once, but that is the case only in IE. What happens is I call my getUploadURL, I make sure the server sends an event that will result in an Event.COMPLETE, so the getBaseURL gets executed, and the listener is removed. If I call the getUploadURL method and put the wrong path, I do not get an Event.COMPLETE but some other event, and getBaseURL should not be executed. That is the correct behavior in FireFox. In IE, it looks like the load() method does not actually call the server, it jumps directly to the getBaseURL() for the Event.COMPLETE. I checked the willTrigger() and hasEventListener() on _loader before assigning the new URLLoader, and it turns out the event has been well removed. I hope I make sense, I simplified my code. To sum up quickly: in FireFox it works well, but in IE, the first call will work but the second call won't really call the .load() method; it seems it uses the previously stored result from the first call. I hope someone can please help me, Thank you, Rudy

  • Boost Asio UDP retrieve last packet in socket buffer

    - by Alberto Toglia
    I have been messing around Boost Asio for some days now but I got stuck with this weird behavior. Please let me explain. Computer A is sending continuos udp packets every 500 ms to computer B, computer B desires to read A's packets with it own velocity but only wants A's last packet, obviously the most updated one. It has come to my attention that when I do a: mSocket.receive_from(boost::asio::buffer(mBuffer), mEndPoint); I can get OLD packets that were not processed (almost everytime). Does this make any sense? A friend of mine told me that sockets maintain a buffer of packets and therefore If I read with a lower frequency than the sender this could happen. ¡? So, the first question is how is it possible to receive the last packet and discard the ones I missed? Later I tried using the async example of the Boost documentation but found it did not do what I wanted. http://www.boost.org/doc/libs/1_36_0/doc/html/boost_asio/tutorial/tutdaytime6.html From what I could tell the async_receive_from should call the method "handle_receive" when a packet arrives, and that works for the first packet after the service was "run". If I wanted to keep listening the port I should call the async_receive_from again in the handle code. right? BUT what I found is that I start an infinite loop, it doesn't wait till the next packet, it just enters "handle_receive" again and again. I'm not doing a server application, a lot of things are going on (its a game), so my second question is, do I have to use threads to use the async receive method properly, is there some example with threads and async receive? Thanks for you attention.

  • Determine whether app is communicating with APNS sandbox or production environment

    - by goldierox
    I have push notifications set up in my app. I'm trying to determine whether the device token I've received from APNS in the application:didRegisterForRemoteNotificationsWithDeviceToken: method came from the sandbox or development environment. If I can distinguish which environment initialized the token, I'll be able to tell my server to which environment to send the push notification. I've tried using the DEBUG macro to determine this, but I've seen some strange behavior with this and don't trust it to be 100% correct. #ifdef DEBUG BOOL isProd = YES; #else BOOL isProd = NO; #endif Ideally, I'd be able to examine the aps-environment entitlement (value is Development or Production) in code, but I'm not sure if this is even possible. What's the proper way to determine whether your app is communicating with the APNS sandbox or production environments? I'm assuming that the server needs to know this in the first place. Please correct me if this is assumption is incorrect. Edited: Apple's documentation on Provider Communication with APNS details the difference between communicating with the sandbox and production. However, the documentation doesn't give information on how to be consistent with registering the token (from the iOS client app) and communicating with the server.

  • Refactor link to show/hide a table row

    - by abatishchev
    I have a table with row which cab be hidden by user. It's implemented this way: Markup: <table> <tr> <td> <table style="margin-left: auto; text-align: right;"> <tr> <td class="stats-hide"> <a href="#" onclick="hideStats();">Hide</a> </td> <td class="stats-show" style="display: none;"> <a href="#" onclick="showStats();">Show</a> </td> </tr> </table> </td> </tr> <tr class="stats-hide"> <td> <!-- data --> </td> </tr> </table> And jQuery code: <script type="text/javascript" language="javascript"> function hideStats() { hideControls(true, $('.stats-hide')); hideControls(false, $('.stats-show')); } function showStats() { hideControls(false, $('.stats-hide')); hideControls(true, $('.stats-show')); } function hideControls(value, arr) { $(arr).each(function () { if (value) { $(this).hide(); } else { $(this).show(); } }); } </script> How to implement the same behavior with one, single link and one, probably, CSS class? My idea - store somewhere a boolean variable and toggle controls visibility relatively to this variable. Are there more?

  • Rails Model inheritance in forms

    - by Tiago
    I'm doing a reporting system for my app. I created a model ReportKind for example, but as I can report a lot of stuff, I wanted to make different groups of report kinds. Since they share a lot of behavior, I'm trying to use inheritance. So I have the main model: model ReportKind << ActiveRecord::Base end and created for example: model UserReportKind << ReportKind end In my table report_kinds I've the type column, and until here its all working. My problem is in the forms/controllers. When I do a ReportKind.new, my form is build with the '*report_kind*' prefix. If a get a UserReportKind, even through a ReportKind.find, the form will build the 'user_report_kind' prefix. This mess everything in the controllers, since sometimes I'll have params[:report_kind], sometimes params[:user_report_kind], and so on for every other inheritance I made. Is there anyway to force it to aways use the 'report_kind' prefix? Also I had to force the attribute 'type' in the controller, because it didn't get the value direct from the form, is there a pretty way to do this? Routing was another problem, since it was trying to build routes based in the inherited models names. I overcome that by adding the other models in routes pointing to the same controller.

  • Opening URL in New Tab doesn't work in existing, programmatically-opened New Window (Firefox)

    - by seth
    I am building a web app, for myself, to control some servers on my home network, and discovered what I think is very odd behavior in Firefox. If you open a pop-up, via javascript, in Firefox, is it then impossible to open a new tab, via javascript in that pop-up? If not impossible, how do you do it? Given a clean, default Firefox 3.6.3 installation... If I open a page in Firefox and then call var my_window = window.open('http://www.google.com','_blank','top=10'); A brand new "pop-up" window opens. However, if instead I call var my_window = window.open('http://www.google.com'); A get a new tab. HOWEVER... If I call the first version var my_window = window.open('http://www.google.com','_blank','top=10'); And then in the new "pop-up" that opens, I call var my_window = window.open('http://www.google.com'); It opens a new tab in the original window, not a new tab in the pop-up. This seems very odd, and not intuitive at all. Why would the call in the pop-up open a tab in the "parent" window?

  • TextBox change is not saved to DataTable

    - by SeaDrive
    I'm having trouble with a simple table edit in a Winform application. I must have missed a step. I have a DataSet containing a DataTable connected to a database with a SqlDataAdapter. There is a SqlCommandBuilder on the SqlDataAdapter. On the form, there are TextBoxes which are bound to the DataTable. The binding was done in the Designer and it machine-produced statements like this: this.tbLast.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.belkData, "belk_mem.last", true)); When I fill the row in the DataTable, the values from the database appear in the textboxes, but when I change contents of the TextBox, the changes are apparently not being going to the DataTable. When I try to save change both of the following return null: DataTable dtChanges = dtMem.GetChanges(); DataSet dsChanges = belkData.GetChanges(); What did I forget? Edit - response to mrlucmorin: The save is under a button. Code is: BindingContext[belkData, "belk_mem"].EndCurrentEdit(); try { DataSet dsChanges = belkData.GetChanges(); if (dsChanges != null) { int nRows = sdaMem.Update(dsChanges); MessageBox.Show("Row(s) Updated: " + nRows.ToString()); belkData.AcceptChanges(); } else { MessageBox.Show("Nothing to save.", "No changes"); } } catch (Exception ex) { MessageBox.Show("Error: " + ex.Message); } I've tried putting in these statements without any change in behavior: dtMem.AcceptChanges(); belkData.AcceptChanges();

  • Nose2 multiprocess error on Windows7

    I was looking into nose2 as a way to get around the restrictions of having both xunit output and multiprocessing in nose1.3. However, when always-on is set to False in the [multiprocess] section, I can only get a single process running, while when running with always-on set to True, I get the following error: ---------------------------------------------------------------------- Ran 0 tests in 0.043s OK Traceback (most recent call last): File "C:\dev\testing\Tests\PythonTests\venv\Scripts\nose2-script.py", line 8, in <module> load_entry_point('nose2==0.4.7', 'console_scripts', 'nose2')() File "C:\dev\testing\Tests\PythonTests\venv\lib\site-packages\nose2-0.4.7-py2. 7.egg\nose2\main.py", line 284, in discover return main(*args, **kwargs) File "C:\dev\testing\Tests\PythonTests\venv\lib\site-packages\nose2-0.4.7-py2. 7.egg\nose2\main.py", line 98, in __init__ super(PluggableTestProgram, self).__init__(**kw) File "C:\dev\testing\Tests\PythonTests\venv\lib\site-packages\unittest2-0.5.1- py2.7.egg\unittest2\main.py", line 98, in __init__ self.runTests() File "C:\dev\testing\Tests\PythonTests\venv\lib\site-packages\nose2-0.4.7-py2. 7.egg\nose2\main.py", line 260, in runTests self.result = runner.run(self.test) File "C:\dev\testing\Tests\PythonTests\venv\lib\site-packages\nose2-0.4.7-py2. 7.egg\nose2\runner.py", line 53, in run executor(test, result) File "C:\dev\testing\Tests\PythonTests\venv\lib\site-packages\nose2-0.4.7-py2. 7.egg\nose2\plugins\mp.py", line 60, in _runmp ready, _, _ = select.select(rdrs, [], [], self.testRunTimeout) select.error: (10038, 'An operation was attempted on something that is not a soc ket') This is running python 2.7.5 (32bit) on Windows 7 in a virtualenv with six-1.1.0, unittest2-0.5.1 and nose2-0.4.7 (I get the same behavior outside of the venv, so I don't think that is the issue here).

  • JSP:Include not rendering the page correctly

    - by sreekanth
    am having trouble with including a jsp page with tag. This is what is happening. I making changes to a portlet application running on Websphere 7 server. This is the hierarchy of the jsp pages. blankPage.jsp --bookingViewTabs.jsp -- availableRooms.jsp meaning blankPage is included in bookingViewTabs which is inturn included in availableRooms.jsp I have 2 problems with this. (1). The blankPage.jsp does not render correctly on the screen. It gets cutoff (2). The other is in blankPage.jsp there is a form called "guestProfileSearchResultsFormId". this form has several hidden fields for data. example, "guestId" which is a child of that form and can be accessed formname.fieldname, but when i include that page into another jsp as the first include(there are several includes on the page) under the another form tag, the form field is not being rendered as a child of the form, but as a sibling of the form. If i change the order and include some other page and include this, it is working as it is supposed to have. meaning with children intact. I don't understand this behavior. I HAVE ATTACHED A GIF IMAGE OF WHAT I SEE ON THE BROWSER Any help is greatly appreciated. Thanks in advance

  • Android Webkit Input elements buggy with CSS3 translate3D

    - by Dansl
    I'm having a couple issues with the Input element in a Webkit Android App i'm developing. Testing on 2.X, but 3.x doesn't seem to have these issues... The app works by having separate Div's for each "page", and I'm using CSS3 translate3D to animate between the pages. Some of those pages include Input elements. When I tap on the input to gain focus, any of my "position:fixed" Div's will shift about 5px from the top, and 5px left. Now the kicker... it will eventually fix itself, and then never happen again when you tap on an input, its only that first time... My other problem, the Input elements are screwy with keyboards, for instance, spell corrections/autocomplete will not input text, and when using Swype Keyboard, you can't "swipe" the word, ONLY individual taps for each letter will input text into the Input element. I've read that a lot of these might be caused by CSS3 Translate3D. But, I've tried just about everything to fix these issues, and I've searched just about every site for a solution, but havent been able to find a fix, or find anyone else with this issue... Does anyone else have these issues, or know of a fix? (Possible solution??) Anyone know of a way to override the default behavior of Input elements in the webkit? I wonder if I can generate my own TextView and position it over these input fields...? Any help is greatly appreciated :)
