Geoffrey De Smet commented on RCP-482:
--------------------------------------
Vldocking is GPL (aka commercial unfriendly) instead of ASL or LGPL,
so this might present a problem of us hosting it in our repo in the first place.
If the sources are uploaded too it's probably ok (but I am not a lawyer).
Since it's GPL I don't see it getting into repo1.maven.org any time soon,
but the bigger issue might be that it could impose that the vldocking code is split into it's own project,
because that integration code probably also needs to be GPL licenced...

> Key: RCP-482
> URL: http://opensource.atlassian.com/projects/spring/browse/RCP-482
> Project: Spring Framework Rich Client Project
> Issue Type: Bug
> Components: Application Framework
> Environment: Windows XP SP2, Java 1.5, Spring-RCP 0.3.0-SNAPSHOT current SVN Head (Revision 1785)
> Reporter: Tobias Vogel
>
> I integrated VLDocking into my application. So far it works pretty well, besides one thing:
> - I open the application with one (or multiple) views (described in the context by VLDockingViewDescriptor") open
> - I choose the "NewWindowCommand" from the window menu (already integrated in a vanilla rcp project)
> - I then again try to close the window again which leads to the NullPointerException
> The relevant line in the DockViewTitleBar (see stacktrace below) looks like this:
> > tb.target.getDockKey().setNotification(false);
> Seems like the dock keys don't get duplicated while duplicating the windows, as the original window doesn't show this behaviour.
> Here's the stacktrace:
> [ERROR,MessagesDialogExceptionHandler,AWT-EventQueue-0] Uncaught throwable handled
