Hi all,
I would like to request for some help regarding the placement of ExpansionNodes with respect to an ExpansionRegion figure.
See the fhe following link for an example figure which shows what I am trying to achieve:
http://www.gentleware.com/fileadmin/media/archives/userguide s/poseidon_users_guide/images/activity_expansion.png
The expansion region is the node which contains 5 nodes; one object, two actions and two expansion nodes. The expansion nodes are the figures which consist of 4 adjacent rectangles.
I have already managed to create a diagram allowing me to draw almost the same figure as shown in the example. The one thing I am currently stuck with is how to let the placement of the expansion nodes to partly overlap the expansion region. Can someone help me with achieving this in my own implementation?
Kind regards,
Niels Brouwers.

Hi all,
I've found out how it was solved with the ActivityParameterNode, and I copied the method and got it working. The ActivityParameterNode uses a custom locator to partly overlap the activity:
org.eclipse.uml2.diagram.common.draw2d.BisectionBorderItemLo cator
However, a (although smaller) problem remains: when repositioning the ActivityParameterNode or the ExpansionNode, the node disappears from the diagram. When repositioning one of the other elements on the diagram, or saving the diagram and then reopen the diagram, the nodes appear on the new location.
Apparently, there is some bug within the custom locator. Anyone has experienced similar behavior? Is a fix available?
Kind regards,
Niels Brouwers.
