Description Camille Letavernier CLA 2012-08-01 09:20:09 EDT 
In the CustomizedTreeContentProvider, calling twice to getElements() with the same input returns two different elements.

Consequently, TreeViewers cannot preserve the selection when they are refreshed. This also causes the tree to be collapsed after each modification.
Comment 1 Gregoire Dupe CLA 2012-08-13 18:32:14 EDT 
I've committed a patch for the bug in the branch 0_2_1.

Committed revision 2641.
Comment 2 Gregoire Dupe CLA 2012-08-13 19:06:15 EDT 
I've committed the same fix in the trunk.

Committed revision 2642.

The bug should be fixed. Camille, please, could you close this bug until you will be sure that the bug is fixed ?

Regards,
Grégoire

This only seems to work partially.

When adding a new child B to an element A, all children of A (i.e. siblings of B) are collapsed. All other cases seem to work correctly.
