• Problem on IE6-8 with jQuery

  - by Alain Fontaine

  Hello guys, I'm stuck here with this IE6 issue.. always a pain. So I'm using jQuery's "live" feature to add a product each time. Then once each dropdown's value is changed, an input field assigned to it changes its value too so when I hit submit, it sends all the info. Everything works perfectly fine except in IE6, IE7, and IE8. I have no idea why... I've gone through the code and everything... so please guys. Help! :) These are all the files: Index.php http://pastie.org/967139 Submit.php http://pastie.org/967140 JS http://pastie.org/967141 Please guys, I'm really stuck here. I would appreciate some help. Thanks, Alain

• The lua stack overflow,is this a bug?

  - by xiayong

  Some days ago, our program crash. I found the crash in lua code. So I check lua code, found the stack overflow. Please look this code In function luaD_precall: 1 if (!cl->isC) { /* Lua function? prepare its call */ 2 CallInfo *ci; 3 StkId st, base; 4 Proto *p = cl->p; 5 luaD_checkstack(L, p->maxstacksize); 6 func = restorestack(L, funcr); 7 if (!p->is_vararg) { /* no varargs? */ 8 base = func + 1; 9 if (L->top > base + p->numparams) 10 L->top = base + p->numparams; 11 } 12 else { /* vararg function */ 13 int nargs = cast_int(L->top - func) - 1; 14 base = adjust_varargs(L, p, nargs); 15 func = restorestack(L, funcr); /* previous call may change the stack */ 16 } 17 ci = inc_ci(L); /* now `enter' new function */ 18 ci->func = func; 19 L->base = ci->base = base; 20 ci->top = L->base + p->maxstacksize; 21 lua_assert(ci->top <= L->stack_last); 22 L->savedpc = p->code; /* starting point */ 23 ci->tailcalls = 0; 24 ci->nresults = nresults; 25 for (st = L->top; st < ci->top; st++) 26 setnilvalue(st); 27 L->top = ci->top; In my program, the p->maxstacksize is 79 before line 5, the current stacksize is 51, after call luaD_checkstack, the stacksize grow to 130. The lua function use vararg, so will run to line 14. Function adjust_varargs will be called. static StkId adjust_varargs (lua_State *L, Proto *p, int actual) { int i; int nfixargs = p->numparams; Table *htab = NULL; StkId base, fixed; for (; actual < nfixargs; ++actual) setnilvalue(L->top++); #if defined(LUA_COMPAT_VARARG) if (p->is_vararg & VARARG_NEEDSARG) { /* compat. with old-style vararg? */ int nvar = actual - nfixargs; /* number of extra arguments */ lua_assert(p->is_vararg & VARARG_HASARG); luaC_checkGC(L); htab = luaH_new(L, nvar, 1); /* create `arg' table */ In function adjust_varargs(), the lua function use “arg”, So luaC_checkGC will be called. In luaC_checkGC, the current lua stack size will be reduce to 65! The call stack like this: luaC_step() singlestep() propagatemark() traversestack() checkstacksizes() luaD_reallocstack() But the p->maxstacksize is 79, the stacksize is not enough… When the program run to line 27,the L->top is bigger than L->stack_last, in the next operation, will cause crash!

• DataContractSerializer case-insensitive datamember bug

  - by Andrew Bullock

  Here is my class: [DataContract] public class EventIndex : IExtensibleDataObject { public ExtensionDataObject ExtensionData { get; set; } [DataMember] private readonly IList<EventDescription> events; public IEnumerable<EventDescription> Events { get { return events; } } public EventIndex() { events = new List<EventDescription>(); } } As you can see, events is marked as a member. When I try and deserialize one of these classes, ReadObject throws a NullReferenceException. After a morning spent inside reflector, it turns out that its trying to deserialize the events collection into the Events getter. If I rename one of the members (events\ Events) I don't have an issue. Is there a way to make this work properly, without renaming workarounds or other such nonsense?

• String.split() method bug in GWT 2.0.3

  - by Domchi

  I'm upgrading a GWT project from GWT 1.7.1 to currently newest version 2.0.3. It seems that new GWT broke String.split(String regex) method - I get the following error on the Javascript side: this$static is undefined This happens in this line of my .nocache.js file: if (maxMatch == 0 && this$static.length > 0) { ...which happens to be a part of String split method equivalent in Javascript. Is there a cure for this, apart from doing string splitting myself?

• PrintableArea in C# - Bug?

  - by Brandi

  I am having an issue with PageSettings.PrintableArea's width and height values. Width, Height, and Size properties claim to "get or set" the values. Also, the inflate() function claims to change the size based on values passed in. However, all of these attempts to change the value have not worked. Inflate() is ignore (no error, just passes as if it worked, but the values remain unchanged. Attempting to set the height, width, or size gives a compiler error: "Cannot modify the return value of 'System.Drawing.Printing.PageSettings.PrintableArea' because it is not a variable". I get the feeling that this means the "or set" part of the description is a lie. Why I want to know this: (Someone always asks...) I have a printing application (C#, WinForm) that for most things is working rather well. I can set the printer settings and page settings objects to control what displays in the print dialog's printer properties. However, with Microsoft Office Document Image Writer, these settings are sometimes ignored, and the paper size returns as 0, 0 even when it displayed something else. All I really want it for it to be WYSIWYG as far as the displayed values go, so I change the paper size back to what it should be, but the printable area, if it is wrong, makes the resulting image wonky. The resulting image is the size of the printable area instead of the value in papersize. Just wondering if there was a reason for this or a way to get it not to do that. Thanks in advance. :)

• UIView Animation: PartialCurl ...bug during rotate?

  - by itai alter

  Hello all, a short question. I've created an app for the iPad, much like a utility app for the iPhone (one mainView, one flipSideView). The animation between them is UIModalTransitionStylePartialCurl. shouldAutorotateToInterfaceOrientation is returning YES. If I rotate the device BEFORE entering the FlipSide, everything is okay and the PartialCurl is displayed okay. But if I enter the FlipSide and then rotate the device, while the UIElements do rotate and position themselves just fine, the actual "page curl" stays with its initial orientation. it just won't budge :) Is it a known issue? am I doing something wrong? Thanks!

• Bug Running Android Tutorial HelloTabWidget under SDK 1.5: "setCurrentTag(getIntent())"

  - by Matt J.

  does not compile. Indeed: even in 1.5, this api, getIntent(), is already listed as deprecated. The error message I get complains that getIntent() does not return a String, but setCurrentTab() expects a string. If I guess and change the line to read: "tabHost.setCurrentTab(1); // was setCurrentTab(getIntent())", then it compiles, builds, but does not run. I get the "stopped unexpectedly" error message from the emulator. I cannot even get Log.d to output, so it seems that it stops 'unexpectedly' very early. So the first and main question is: what is the correct fix to "tabHost.setCurrentTab(getIntent())" in the final line of OnCreate() in http://developer.android.com/resources/tutorials/views/hello-tabwidget.html? The second and simpler question is: did I guess right in replacing 'mTabHost' with tabHost in the one place where that occurs?

• AjaxMin4 bug with Visual Studio 2010 RC?

  - by KevinUK

  When I compile my solution I get 2 errors which I did not get with version of 1.1 of AjaxMin. The "SourceFiles" parameter is not supported by the "AjaxMin" task. Verify the parameter exists on the task, and it is a settable public instance property. The "AjaxMin" task could not be initialized with its input parameters. If I re-install AjaxMin4 then reload VS it works again until I reboot the PC. Is this a known issue and is there a fix?

• Session bug using facebook-connect-with-authlogic in Rails

  - by Jesse

  I'm trying to follow this article: http://ryanbigg.com/2010/03/testing-facebook, but I'm stuck. I think the problem is with my session, in that the current_usermethod comes up with nil for session[:facebook_session]. According to the original authlogic, it says to use the active_record_store for sessions: # config/environment.rb config.action_controller.session_store = :active_record_store # db/schema includes create_table "sessions", :force => true do |t| t.string "session_id", :null => false t.text "data" t.datetime "created_at" t.datetime "updated_at" end The article calls for the use of cookies. I'm confused; can I use cookies and the active record sessions? I'm also confused by the use of cattr_accessor :current_user from within the User model -- current_user still goes in the application controller, right? Please help.

• Method to capture a screenshot of user's browser to aid in bug reporting

  - by Buzz

  I'm looking for a way to make it easy for technically unsophisticated users to submit screenshots of their browser to me, to aid in debugging web application problems. There will be a button on all pages inside a web application they can use to report problems, which I would like to submit a screenshot (among other things). http://www.snapabug.com/ is very close to what I want, but I need to be able to customize a few things that service won't let me. Production environment is LAMP. I expect there must be something Flash-based that can do this, but I've not been able to find something. Thanks!

• Need Workaround for Outlook 2007 HTML Email Rendering Bug (Horizontal Gaps)

  My html email newsletter design doesn't render properly in Outlook 2007. There is a white horizontal gap towards the bottom which breaks borders and backgrounds. I've had this happen before and have no idea how to work around it. Any suggestions? I've posted the source here. It renders just fine except in Outlook 2007 (Word 2007). By the way, you can preview the problem without Outlook, by opening the source with Word 2007.

• Odd Infragistics UltraComboEditor data binding non-bug

  - by Richard Dunlap

  Within an Infragistics 8.2 UltraComboEditor, we had the following properties set via C#: DataSource = dataSource; ValueMember = "Measure"; DisplayMember = "Name"; DataBindings.Add("Value", repository, "Measure"); DataBindings["Value"].DataSourceUpdateMode = DataSourceUpdateMode.OnPropertyChanged; where dataSource was an array of objects, each with a property Measure, and repository was an object with a property Measure. (Those strings are actually constructor parameters -- just using explicit strings to simplify the example.) In the course of some refactoring, the name of the property on the objects in the array was changed to BaseEnum (the objects are actually wrapped enumerations, for the curious), but the name of ValueMember above was not changed. And yet, the combo box binding continued to work through initial testing, beta testing, and even after release... until two customers emailed in noting that the combo box was no longer changing the underlying parameter. We were able to dig out the problem by careful study of the source code repository... despite being in the awkward position of not being able to replicate the buggy behavior internally. Two part question: What's happening under the hood that allowed the binding to continue to function, and/or what might be unique about those two users that caused the binding to (correctly) fail? (O/S version isn't alone the answer, and we get the unexpectedly functioning binding on machines that have never had a version of the software before, so we're not looking at rogue binaries). Are there tools that might have been able to warn us about the misbind, even if something was cleaning up behind?

• Exception.Data population bug?

  - by Christopher

  Okay, .NET geniuses, here's the relevant part of my code: adapter.Fill(table); return; } catch(Exception ex) { SqlException sqlEx = ex as SqlException; I have an exception that's being thrown by adapter.Fill(), and when I put a breakpoint on the first line in the exception handler, the Exception.Data property already contains a key that is unique to my application. The thing is that it does not happen every time, but only when this exception is thrown within ~2 seconds of it last being thrown. Explain that!! :) Thanks!

• dll's loaded through reflection - Phantom Bug

  - by Seattle Leonard

  Ok, I got a strange one here and I want to know if any of you have ever run accross anything like it. So I've got this web app that loads up a bunch of dll's through reflection. Basically it looks for Types that are derived from certain abstract types and adds them to the list of things it can make. Here's the weird part. While developing there is never a problem. When installing it, there is never a problem to start with. Then, at a seemingly random time, the application breaks while trying to find all the types. I've had 2 sites sitting side by side and one worked while the other did not, and they were configured exactly(and I mean exactly) the same. IISRESET's never helped, but this did: I simply moved all the dll's out of the bin directory then moved them back. That's right I just moved them out of the bin directory then put them right back where they came from and everything worked fine. Any ideas? Got some more info When the site is working I notice this behavior: After IISRESET it still works, but recycling the app pool will cause it to break. When the site is broken: Neiter IISRESET nor recycling the app pool fixes it, but moving a single dll out then back in fixes it.

• Flex 3.5 Accordion and TabNavigator Index Change Bug

  - by majgis

  I'm using Flex 3.5 with Adobe Flex Builder 3. I have found that if you very rapidly click between multiple headers of an accordion component or the tabs of TabNavigator, these components will begin to exhibit odd, unexpected behavior. Has anyone else experienced this behavior and do you know of a patch that can prevent the user from getting in a situation where the tab/header they click on is not the one made visible?

• Flex 3.5 Accordion and TabNavigator selectedIndex Bug

  - by majgis

  I'm using Flex 3.5 with Adobe Flex Builder 3. I have found that if you very rapidly click between multiple headers of an accordion component or the tabs of TabNavigator, these components will begin to exhibit odd, unexpected behavior. Once this behavior has been evoked, even trying to set the selectedIndex programmatically does not end in the desired result. Specifically, if set the selectedIndex to zero (or click on the first tab/header) it might temporarily hop to that index but then will finish on a different index. Has anyone else experienced this behavior and do you know of a patch that can prevent the user from getting in a situation where the tab/header they click on is not the one made visible?

• Did I find a bug in WriteableBitmap when using string literals

  - by liserdarts

  For performance reasons I'm converting a large list of images into a single image. This code does exactly what I want. Private Function FlattenControl(Control As UIElement) As Image Control.Measure(New Size(1000, 1000)) Control.Arrange(New Rect(0, 0, 1000, 1000)) Dim ImgSource As New Imaging.WriteableBitmap(1000, 1000) ImgSource.Render(Control, New TranslateTransform) ImgSource.Invalidate Dim Img As New Image Img.Source = ImgSource Return Img End Function I can add all the images into a canvas pass the canvas to this function and I get back one image. My code to load all the images looks like this. Public Function BuildTextures(Layer As GLEED2D.Layer) As FrameworkElement Dim Container As New Canvas For Each Item In Layer.Items If TypeOf Item Is GLEED2D.TextureItem Then Dim Texture = CType(Item, GLEED2D.TextureItem) Dim Url As New Uri(Texture.texture_filename, UriKind.Relative) Dim Img As New Image Img.Source = New Imaging.BitmapImage(Url) Container.Children.Add(Img) End If Next Return FlattenControl(Container) End Function The GLEED2D.Layer and GLEED2D.TextureItem classes are from the free level editor GLEED2D (http://www.gleed2d.de/). The texture_filename on every TextureItem is "Images/tree_clipart_pine_tree.png" This works just fine, but it's just a proof of concept. What I really need to do (among other things) is have the path to the image hard coded. If I replace Texture.texture_filename in the code above with the string literal "Images/tree_clipart_pine_tree.png" the images do not appear in the final merged image. I can add a breakpoint and see that the WriteableBitmap has all of it's pixels as 0 after the call to Invalidate. I have no idea how this could cause any sort of difference, but it gets stranger. If I remove the call to FlattenControl and just return the Canvas instead, the images are visible. It's only when I use the string literal with the WriableBitmap that the images do not appear. I promise you that the value in the texture_filename property is exactly "Images/tree_clipart_pine_tree.png". I'm using Silverlight 3 and I've also reproduced this in Silverlight 4. Any ideas?

• Firefox innerHTML Bug?

  - by M. Singleton

  I have a simple piece of HTML <p id="skills">Skills</p> in Firefox 3.6.3 when I call (with JQuery): $("#skills")[0].innerHTML = "some new text" Firefox renders it as <p id="skills"><a xmlns="http://www.w3.org/1999/xhtml">some new text</a></p> Where in the world is that link coming from?? (note the same thing happens by calling $("#skills").html("some new text") with JQuery)

• jQueryUI Ajax.NET Postback Bug

  - by nigative

  Hi, I have this ASP.NET page with ASP.NET UpdatePanel and jQueryUI droppable and sortable components. The page works fine in all browsers, but doesn't in Internet Explorer (IE8 tested). After I try to call ASP.NET AJAX event (by pressing my asp.net button inside the UpdatePanel) my sortable list stops working properly inside IE browser and the browser throws the following error: Message: Unspecified error. Line: 145 Char: 186 Code: 0 URI: http://code.jquery.com/jquery-1.4.2.min.js I found out that the problem is caused by the code on line 66: $("#droppable").droppable(); If I comment it out, the sortable list works fine after ajax postbacks. But it doesn't make sense. Does anyone know what could be wrong? Thanks. P.S. I am using jQueryUI 1.8.1 and jQuery 1.4.2
