Deletion of entities does not unset the non-containment references [message #731811]

Hi,

I have the following Scenario:

A has a non-containment reference to B. Now if I use a RemoveCommand on B, its reference from A is not automatically unset, hence leaving some dangling references.

How can I ensure that all the references are also deleted on deleting an object.

Thanks,
Best Regards,
Nidhi

Nidhi, 
 
Is this constructor for the delete action being called with true as
the second argument? 
 
 public DeleteAction(EditingDomain domain, boolean
removeAllReferences) 
 
That will ensure that as DeleteCommand rather than a RemoveCommand
is used. 
 
 public Command createCommand(Collection<?> selection) 
{ 
return removeAllReferences ? DeleteCommand.create(domain,
selection) : RemoveCommand.create(domain, selection); 
}
