Hi,
I have an action in a reference widget that needs user input. I haven't
found a way of collecting user input from the property sheet itself, so
I ended up coding an external Java Action that gets input using a popup
dialog. Below I include two classes, the Java Action implementation and
the dialog service (coded so it can be used as a service class in a
diagram), so others may use it. I didn't find out how to pass the
selection (among referenced elements) as arguments to the action, so in
the VSM I added a Java Action Parameter named "slots" with
var:selection as the value expression, that is picked up by the code
below.
Enjoy!

So what? :) did you succeed in doing what you want or do you still have
a question?
Note that you can define user variable from a selection of model
elements in a dialog box using "Select Model Element Variables" [1]
