resize(make smaller) of figures on diagram fails [message #155830]

I have the problem that making a figure smaller in the diagram editor does
not work while making it bigger is no problem at all. It seems to be
related to ellipse objects only, but I am not sure. I am using Eclipse
europa with the according GMF.

Hello Heinz,

Looks like the figures you have inside your "top-level" one has some minimum
size specified.

Well its not specified at least.
On the diagram editor I can make it bigger several times. But I never can
make it smaller then the last resize operation.

It is the ellipse used for the StartStateFigure.
Check definition in the .gmfgrapf file:

Hello Heinz,

Did you seen http://www.eclipse.org/modeling/mdt/?project=uml2tools#uml2t ools
project (CCing coreponding newsgroup)? Looks like this diagram is already
implemented there. You can probably at least reuse some existing figures
for your diagrams.

Hello Heinz,

In UML2Tools (you can find gmf definition files in the org.eclipse.uml2.diagram.def
plugin, in particular at /behaviors/activityDiagram_controlNodes.gmfgraph#//InitialPs eudoStateNode
and #//FinalStateNode)
these nodes are defined as not resizable. However, just removing the resizeConstraint="NONE"
should provide you with correct resize behavior.

Regards,
Michael
