Using DND in RCP Eclipse 4 application model [message #853663]

Hi,

I've been following the Lars Vogel Eclipse 4 RCP turorial using 4.2M6:

http://www.vogella.com/articles/Eclipse4RCP/article.html

I now have a simple three part RCP skeleton. I decided the extend the application model by adding drag and drop to the parts using the DnDAddon and CleanupAddon addons. Sure enough, just adding these to the model gives the new functionality.

My problem is having run up the application and dragged the parts to give a new layout, on restarting the application I often get IllegalArgumentException with the message:

"part ... is not a child of this container"

Even with the exception, sometimes the new layout is restored OK. Other times I loose one or more of the parts.

Is this a bug or do I need to add some additional functionality to support DND?

Thanks for any help.

Steve.

There've been some problems with DND which got fixed in last weeks
(though IIRC they have happened while dragging)

Please try a nightly build and if you still get errors on restart log a
bug with steps to reproduce.
