[emf-dev] [EMF Forms] Loading Model problem

[Javier Alfonso]

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?

Please use the forum to ask question. The EMF Forms project uses the
EMFT forum. Note there there is not enough information about what
you're doing to guess at the problem. If you have an exception, there's
a stack trace. Include that in your forum post.

sorry to keep bothering you, i posted a new question at
https://www.eclipse.org/forums/index.php/m/1752818/#msg_1752818
the problem is that i create an editing domain to load an work with my
model, but it seems that in some scenarios, emfforms is creating a new
editingdomain after rendering a component, resulting in consistency
problems, any suggestions?
