I spend hours of finding the reason for my problem, not beeing able to =
create a dynamically registered SpecializationType like the person in =
this post tried before. I have the same problem like him that I get a =
"not-allowed" cursor when I use a dynamically created tool palette =
entry. I used the tutorial from this site. First i thought, the reason =
is, that I didn't use a semanticHint when using the kind =
"org.eclipse.gmf.runtime.emf.type.core.IHintedType" for the =
specializationType of the =
"org.eclipse.gmf.runtime.emf.type.core.elementTypes" extension point. =
Even if i add the semanticHints for the Node viewClass of the =
"org.eclipse.gmf.runtime.diagram.core.viewProviders" extension point in =
the generated diagram code by hand because of the problem described in =
this post it's not working. The request to create a new Element always =
returns an UnexecutableCommand. By comparing the elemant creation =
process of my project and the logic example i found out, that the =
containmentFeature of the CreateElementRequest is not initialized =
correctly in my case. The problem for tis is, that there are no =
DefaultContainmentFeatures are set in the generated EditHelper of the =
highest container. If you take a look into the class =
" org.eclipse.gmf.examples.runtime.diagram.logic.internal.edit helpers.Cont=
ainerElementEditHelper" of the logic example you will find a static call =
inserting the defaultContainmentFeatures in line 33 to 37. This seems to =
be added by hand. So the question is whether these entries should be =
generated automatically.
I tryed to add the DefaultContainmentFeatures by hand but that doesn't =
really solve my problem.
There is something strange I don't understand and what could be the =
reason for my problem. If I look into the method =
"getCreateCommand(CreateElementRequest req)" from class =
" org.eclipse.gmf.examples.runtime.diagram.logic.internal.edit helpers.Cont=
ainerElementEditHelper" it calls "return super.getCreateCommand(req);" =
but if I look into my generated EditHelper for the Container it returns =
null by default for this method.
So I don't really know, what's the real problem. Maybe the logic example =
is based on an old version and the workflow for creating =
specializationTypes is different now!?
I hope someone can help me because i'm stuck in this problem and can't =
go on.
thanking you in anticipation
