Hi,

I created normal GMF project with some nodes and connecting link.
But now I want to insert nodes and connect them through wizard (EWL).
I have created .ewl file in which I have written code for the same i.e. creating new node and connect it with existing node through link.
e.g.

say in diagram i have like node A connecting to node B with link

A -----> B

I clicked on link and through wizards i entered new node C in between A and B. which will looks as follows,

A----->C------>B

Nodes are coming properly but connecting links are not coming on diagram, although its showing in node C and B as inputLink in property view.

But when I refreshed manually (F5), links appears ( I don't want user should do this.) . But they are not remain as it is. i.e When I closed diagram and opened it again they are gone. Sad

Anybody having any idea about the same. Please do reply.

NOTE : all the above stuff I am doing inside a compartment. (is that making mess. I don't know )

Regards,
-AG

Hi AG,

I've seen this issue before, but haven't quite figured out the root cause. A workaround is to force GMF to refresh the contents of the compartment.

Assuming a simple Statemachine metamodel, the following operation should suffice. (The states reference is the compartment).

operation forceRefresh() {
	var s : new State;
	Statemachine.all.first.states.add(s);
	delete s;
}

Then add a call to the operation at the end of the do part of the EWL wizard:

do {
	// The rest of the do block...

	forceRefresh();
}

Hope this helps.

Cheers,
Louis.

Hi,

I've had a chat about this with Louis offline and he said he has a
workaround for this so I guess he'll get back to you on this shortly.

Cheers,
Dimitris

Hi Louis and Dimitris,

Thanks for reply, I will definitely try your approach. But meanwhile I succeed to refresh the edtior diagram by using adator notification which also solved my issue.

Once again Thanks for help.
