I loaded model from file to delete an element and all links/edges with it.

Since I figured out that pop menu "Delete from Model" can do the job perfectly.
I wandered to use the command .
My code goes as belows:

ResourceSet resourceSet  = new ResourceSetImpl();
TransactionalEditingDomain domainx = TransactionalEditingDomain.Factory.INSTANCE.createEditingDomain(resourceSet);
Resource res = domainx.loadResource(fileUri.path());
xxxImpl toDelete = (xxxImpl)((xxxModelImpl)res.getContents().get(0)).getXXX().get(0);

IOperationHistory history = OperationHistoryFactory.getOperationHistory();
DestroyElementRequest desRequest = new DestroyElementRequest(toDelete, true);
history.execute(new DestroyElementCommand(desRequest), new NullProgressMonitor(), null);

however , it goes not as i wanted . The code delete the element indeed,while the edgs goes still. it causes the problem that i can not open the file any more.

What should I do ,Could you please give a helping hand?

Hi,

did you try to simply delete the semantic model element by using an EMF command? The command would be DeleteCommand. You can create a new command by using DeleteCommand.create(...). This should do the job.
