Hello,
What does not work? Do you have an exception that could give an idea of
what happened?
The proper method to load an existing model is as presented in your link
org.eclipse.sirius.business.api.session.Session.addSemanticResource(URI,
IProgressMonitor).
Regards,
Steve

Is your "Error Log" view open (Window/Show View/Others...)? If it is not
silently catched, the exception should be available there. Are you sure
you have the proper URI for the model to load?
I am not sure why you want to load a model in the predicate expression
of a conditional style. It seems more performant to have this model
loaded in your session and have the predicate expression only looking
for a specific model in the current session.

Hi,
You can place a breakpoint in your java service and debug it step by
step where you call
org.eclipse.sirius.business.api.session.Session.addSemanticResource(URI,
IProgressMonitor). Can you provide a sample? I have too limited
information to help you.
Regards,
Steve
