Hi Everyone,
When the user double clicks on a figure I launch another editor who's
main model is the model that the double clicked figure represents. In
the second editor I add objects to an EList contained in the model.
However, when I close the 2nd editor and double click on the figure
again, the elements I added to the EList do not appear there. I am
generating the Model via an Omondo class that has a 1 to -1 containment
relationship to another object.
pseudo code:
openEditor( myModel );
editor opens up sets the contents to myModel.
myModel.getElements().add(element1);
System.out.print(myModel.getElements().size()); //size increased by one
Next time i open the editor i verify that myModel is the same instance
as the one i added the element previously. However, the size of
myModel.getElements().size() is the same as before i added an element.
If I edit a property element via the property View the change is
observed on the first editor as well as any other time I open a second one.
Any ideas?
Thanks,
Angel

I tracked it down to the emf generated code removing the element
whenever an element already in the list was inserted into another EList.

Why are you using EMF, what good is it for you?
What is Omondo, why are you using that?
Just some general questions since I am seeing a lot of EMF users
starting to be GEF users as well.
Thanks,
CL

The use of EMF is due to the guidance of IBM's RedBook on GEF and EMF.
The use of omondo is due to me being able to design an EMF model
graphically and generate the source code for the emf model ( for free).

Nice!
Where is this IBM RedBook. I wonder if EMF would be any good for me?
