hi everyone!
I've another problem.
I've been reading a lot of "how to" create Node's, but everything I found
is to modify the EditPolicy's.
My problem is this:
I have like 2 models...
---------- ------
| My model |<- 1 ------------------ 1-* -->| Node |
---------- ------
The users use "MyModel" when they're working wth the software.
The problem is that many actions that the user can do over "MyModel" must
be reflected in its Node's.
in "MyModel" the user can set it as "deleted". Thats means that the object
is there, but the user can make any action over it, and ofc course, the
Node's of this object must be deleted(this is OK). The problem is when
the user set deleted to "false", thats means that the user can mkake
actions over this object, and of course the node's deleted previously must
be added another time in the diagrams.
my actions "save" as fields this XXXNodeImpl and the NodeImpl(View). I
created a Transactional command with the EditingDomain of the editor(the
diagram is opened). I can deleted the Nodes doing this...
((ScenarioNodeImpl) node.getElement()).setActivityScenario(null);
But I can't re-add the node to the diagram doing this...
ActivityScenarioImpl scenario = (ActivityScenarioImpl)
diagram.getElement();
node.setActivityScenario(scenario);
The error is the...
Error: Cannot modify resource set without a write transaction
When a Create the Request to create the command, i put the actual domain
of the editor opened.
Please help me!!!
if you don't undersatnd something, please answer me, because I know that
my english is SO BAD!! sorry :(
THNAKS a LOT!!

Hi Carlos,
I assume the problem appears in the following line:
node.setActivityScenario(scenario)
Have you tried using SetCommand to set this feature? Here is an example
for how it works (names may differ):
SetRequest setRequest =
new SetRequest(node, ??Package.eINSTANCE.
getScenarioNode_ActivityScenario(), scenario);
SetValueCommand setCommand = new SetValueCommand(setRequest);
editingDomain.getCommandStack().execute(
new ICommandProxy(setCommand));
?? is the package name of your EMF data model.
Regards,
Artun
