Minimization Of PartStacks Confuses The Workbench [message #903465]

I've been exploring e4 RCP app development under Juno and threw together a test app with some PartSashContainers and PartStacks. The app includes the MinMax, DnD, and Cleanup Addons so the truly useful real-estate management features work again.

When the app starts it looks like attachment E4Test1Start.png.

If I minimize e.g. the PartStack that contains Tab2 and Tab3 the workbench gets confused as shown in attachment E4Test1AfterMinimize.png.

At this point the app is gone.

This seems like a pretty basic capability to be broken. Has anybody else seen this behavior?

File a bug and attach your example application.

Eric Moffatt patiently identified the problem: I had left the default PartStack ids in the e4xmi file. The defaults happen to be identical. Make sure the ids are unique and the problem goes away.

Might be better if the model editor came up with unique ids if only by sticking a unique number on the end. And... maybe issue warnings when potentially troublesome situations like this are created by the user.
