Description Laurent Redor CLA 2016-06-29 05:54:08 EDT 
Unlike classical container, when a regions container is drag'n'dropped from
a container to another one, it loses is size.
In Sirius 4.0, the behavior is different between "Horizontal Stack" and "Vertical Stack". In "Horizontal Stack", the regions container is auto-sized after the drag'n'drop. In "Vertical Stack", the regions container is auto-sized only in one direction and the regions are auto-sized (the same bug concerning size of regions as in bug 495046).

After fix of bug 495046 and of bug 495119, the behavior is similar in "Horizontal Stack" and "Vertical Stack": the regions container is auto-sized after the drag'n'drop.
This is probably due to the layout specificity of the regions container (always in {-1, -1}, the dimension is handled by its region children).

Steps to reproduce:
* Open VStackDiag with DnD (of https://git.eclipse.org/r/76180)
* Drag'n'drop "cccc" from "aaaa" in diagram
* KO: The new "cccc" container is auto-sized.

Thanks for your detailed bug report.
We have reproduced this issue and we consider it as valid.
