The problem: I created my user interface successfully, using the
default viewers, i created my objects, edited them and persisted them
using XMI, everything ok, the problem begins when i load the saved
model, it is rendered ok, i can see everything, but when i try to add
new elements or try to edit the existent, i get a null pointer
exception, it is like the view doesn't know how to edit or create new
objects.
My load and save XMI code is based on Vogellas tutorial, maybe the
problem is in the way i assign the loaded objects to the rendered object?
The code i'm using is:
C c = null;
c = (C) resource.getContents().get(0);
and then i render c using the SWT renderer.
The difference to a non saved object is that i use the factory.create
method
Any suggestions?
