How do I implement complex model changes via EOperations? [message #61458]

Hello,

I have a question concerning complex model changes via an EOperation and
generally about multiple view support of GMF.

Let's take the mindmap tutorial as example: If I create both the
EMF-Editor and the GMF-Editor the EMF-Editor displays the changes. But
if I change something in the EMF-Editor the GMF-Editor doesn't "see" the
changes until I reload the model file.

Does GMF allow synchronisation with model changes made by another editor
or is this a general constraint? If it allows multiple views, how do I
generally implement them?

So, if I have a complex model change one of my EOperation performs, how
do I implement this? My first approach was to build an action that
affects directly the semantic-model. Unfortunately a TransactionManager
seems to cancel this operation. I took a look at the Requests in
org.eclipse.gmf.runtim.diagram.ui.requests but at a first glance there
seemed to be no obvious choice for such a request. What would be a
general approach to realize such a complex change operation?

Thanks and greetings,
Alexander

Please search i the newsgroup. There was a number of posting concerning
synchronization of GMF diagrams with each other. The same ideas could be
used to handle synchronization of the GMF diagram with EMF-generated editor
contents.
