------------------------------

Koen,

XmlAdapter.initialize(SemanticElement) is invoked when loading the PD diagram, but not when adding objects from the palette (which is when I need to initialize my semantic elements), so I don't believe this approach would work.

I'm not very familiar with the design behind GD, but my first thought was that it was the semantic elements (the "model objects"?) themselves that should get initialized, and that the xml adapters etc. would just get updated to reflect this (obviously this is not the case when reading the xml, when the xml adapters are used to re-create the semantic elements). Because of this it seems to me like the GD should provide some way of creating initialized semantic elements, for example by invoking some SemanticElement.initializeNew() - like method. This code would get invoked when adding objects from the palette (I think that may be the only case), but not for example while loading the diagram from xml (however, I'm leaving the design up to you - I just need one way to do this).

Thanks, John

> For example, whenever an 'EndState' node is added to the diagram, I need for it to be initialized with a particular event, action, and some action properties. I have made some minor changes to the GD code in order to support this, as described in the following post: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=108175
> It would be very helpful if these changes, or similar functionality, can be included in 3.1, as I wouldn't need to keep maintaining my own custom version of the GD feature. I'd be happy to post a patch, if that helps (while my changes are very simple, as described in the post)
