hi,
i've got a problem, i generated two editors by using the gmf-dashboard.
The first one works fine, but if i use the second one, something does
not work, this is very confusing for me. I tryed it a lot of time from
the beginning, but the same failure appears every time. If i want to
create a new node from palette or diagram nothing happens, i also
started the editor in debug mode and discovered that the
createNodeFigure-methods are not called, there should be a notiyfication
fired and this notification should trigger all needed actions to create
and display the node in the diagram, it seems to me that this is not
done. Has anybody an idea about solving this problem or does anybody
know where my faults are located during the creation-steps? If someone
has a hint, please send me an answer.
kind regards Robin

Hi again,
i found something new !
The Problem is in every CreateCommand doExecuteWithResult in edit.commands.
I.E. if i want to create a new State so StateCreateCommand has the
protected CommandResult doExecuteWithResult(IProgressMonitor monitor,
IAdaptable info) throws ExecutionException {
State newElement = SeftFactory.eINSTANCE.createState();
Seft owner = (Seft) getElementToEdit();
owner.getStates().add(newElement); // *1
doConfigure(newElement, monitor, info);
((CreateElementRequest) getRequest()).setNewElement(newElement);
return CommandResult.newOKCommandResult(newElement);
}
*1 : if i inspect this line the information is: An exception occurred:
java.lang.UnsupportedOperationException
But if i just inspect owner.getStates() befor and open the data (list)
and than go on, everything works and the symbol is drawn, otherwise (the
usual case is that) this Exception forces a rollback and an
ExecutionException.
So does ANYBODY know how to fix this or what is worng here, its very
confusing for me.
Kind regards Robin.

hi i got the solution by my self. just surround the line with a
try-catch-block now it is working.
protected CommandResult doExecuteWithResult(IProgressMonitor monitor,
IAdaptable info) throws ExecutionException {
State newElement = SeftFactory.eINSTANCE.createState();
Seft owner = (Seft) getElementToEdit();
try{
owner.getStates().add(newElement);
}catch (UnsupportedOperationException e) {
// TODO: handle exception
}
doConfigure(newElement, monitor, info);
((CreateElementRequest) getRequest()).setNewElement(newElement);
return CommandResult.newOKCommandResult(newElement);
}
