Vaadin 6.5 pre 2 and nightly builds - persistent shadow bug

Hello,

I wasn’t sure where I should post this since it’s related to the pre-release of Vaadin 6.5 (and all other nightly builds of 6.5 I’ve tried), but I thought I’d mention it in case it helped you guys.

In my application (which is now using Vaadin 6.5 pre 2), I noticed that every so often when I close a subwindow, the background shadow is left behind. This has happened at least 5-6 times already. It’s intermittent and doesn’t always occur, but it does occur enough that it is very noticeable. Once the window shadow is there alone, there is no way of moving it and all components under the shadow are inaccessible.

Here is a screenshot of the behaviour:

If you guys need any other information, please let me know.

Hi,

Try adding ?debug to your URL and see if you get something in the debug window. Either when you start the application (for instance that widgetset or theme version does not match the servlet version) or when the shadow remains (most likely a javascript error).

Hi Artur,

I ran my application with the ?debug URL and reproduced the error. The debug log below shows that the widgetset and the theme are the same version 6.4.9 but I still get a warning saying they do not match, how is this possible?:


Drag=move, shift-drag=resize, doubleclick=min/max.Use debug=quiet to log only to browser console.
Widget set is built on version: 6.4.9
Warning: widgetset version 6.4.9 does not seem to match theme version

Thanks,

Any insights on this? I’m having this problem with Vaadin 6.4.9 as well. I have reproduced this issue in Windows 7 FF/IE and Mac OS X FF.

Thanks,
Ajay

Hi,

I see two distinct problems in the logs but sadly the stacktraces help really little as the widgetset is compiled as obfuscated. Could you recompile it using the “pretty” mode and see if you can reproduce the errors? That should at least show in what function the error occurs. Another option would be to run it through the GWT Development mode and you should get a real java stack trace when an exception occurs or you can even set it to break on the exception and you can see where in the code it occurs and maybe why.

The first problem, which occured two times is:

364(TypeError): $doc[eoc + this.k]
.load is not a function stack: un([object Array]
,[object Object]
)

The second might require GWT dev mode to find out the reason as it is inside an AttachDetachException.

671 One or more exceptions caught, see full set in AttachDetachException#getCauses

I would recommend PRETTY mode and/or GWT dev mode to find out more. If you can get a stack trace with real function names it should be possible to fix. It is also of course possible that the problem does not come from Vaadin but from some add-on that you might be using. Either way debugging a bit should tell you more.

The message that the theme version does not match is hidden by the theme (using CSS) but if you copy/paste the contents it might still be copied. So this part should be ok.

Artur,

It looks like there was an error in my custom widget when I am attaching and detaching the GWT component. I neglected to check if the polling thread was set to null which it was after a “timeout”. After a timeout, if detach() was called, it would reach a null exception which would in turn cause the “persistent shadow”.

I appreciate you pointing me in the right direction :slight_smile:

Thanks,
Ajay
