Programmatically update diagrams + write transaction [message #1106640]

Hi.

I am working on refactorings for UML models triggered from whithin the context menu of a graphical UML model element in Papyrus (e.g., an operation 'foo()').

There are (so far) two problems with this:

1. If I move the element (e.g., operation 'foo()') to another class (e.g., by using refactoring 'PullUpOperation') using the UML API, the corresponding diagram is not updated. Is there a way to force this update programmatically?

2. If I add a new element (e.g., a parameter 'bar' to operation 'foo()') using the UML API, I get an exception 'cannot modify resource set without a write transaction'. I found out that Papyrus uses a read-only editing domain (PapyrusROTransactionalEditingDomain). Does this mean that the UML model can not be modified by inserting new elements programmatically?

Best regards,
Thorsten

Actually, the name of this class is not really accurrate. It is actually an EditingDomain which also has support for Read-only resources.

The main issue, in your case, is that it is Transactional. You need to start a transaction before you can actually start modifying the model. For example:

Command command = ...; //An EMF Edit Command
editingDomain.getCommandStack().execute(command); //The command stack handles the transaction
