Due to specific layout constraint of regions container, the auto-size mechanism is not the same as others kinds of container.
Since Sirius 4.1 (in progress), the region container is considered as auto-sized as soon as it contains at least one region. The size "responsibility" is handled by the regions.
It will be interesting to allow the "Auto Size" if at least one of its regions is not auto-sized.
A first step would be to always autorize "Auto Size" action on regions containers.

Currently, as workaround, the "Auto Size" action can be launched on one of the regions to auto-size all regions.


The feature needs to override the default action (org.eclipse.gmf.runtime.diagram.ui.actions.internal.AutoSizeAction), that is constraint by the {-1, -1} layout constraint.

AutoSizeAction.getCommand(Request)
...
				if (containerWidth.intValue() != -1
						|| containerHeight.intValue() != -1) {
					foundNonAutosizedPart = true;
				}
