How do I add a SignalEvent trigger? [message #489705] Mon, 05 October 2009 15:34 Go to next message

Hello,

just doing my first steps in Papyrus. With Papyrus it seems as if I
finally found my tool for my MDD endeavours. :-)
I already mastered the first hurdle, i.e. to find out how to set up a
State Machine diagram (it's not really obvious that you can only create
it as an ownedBehaviour of a classifier when you come from UML2tools).

My current problem is that I want to set a SignalEvent as a trigger for
a transition, but the menu item is grey. The other events are
accessible. How can I make use of a SignalEvent trigger?

Greetings,

Michael

("Use the source, Luke.")

TriggersComposite.java:
if((behavioredClassifier instanceof org.eclipse.uml2.uml.Class) &&
((org.eclipse.uml2.uml.Class)behavioredClassifier).isActive( ))
signalEventItem.setEnabled(true);

Would be nice if that became somewhat more obvious while working with
the program. Probably one should not disable the item but pop up a
warning dialog.

It does make sense to adapt the selection menus so you can't do silly
things, but the problem is who knows all those details of UML? And if
you don't know there is no way to find out why something does not work
for you except to get the spec and read various bits and then try until
it works.

I think that we should use the EclipseUML2 model validation to know if something is acceptable or not.
It works really well Very Happy
I mean that you have a file named .uml in your project which is either related to the full project or just to the diagram. You can click on this file > Model Validation. What is legal in UML 2 is validated at model level using the model validation process. It always work and better than trying graphical model validation.
Using this model validation you will get warnings and errors.

I understand that if you use transformation layers (e.g. EMF or GMF) to get an xmi this could be a problem, but this is not usually what happen because these framework work pretty well too.
Everybody knows my personal point of view saying that the best transformation is no transformation but you can do as you want because all approaches are correct.

Vlad,
