Create a connection between two nodes programmaticaly [message #630535]

I tried to create a connection between two nodes programmatically by adding the semantic connection elements. The problem is that the notation is not refreshed automatically so I don't see the link unless I close and reopen the diagram.
I tried all the internet solutions but without success.

Please help.

Thanks

Can you post the code?. I have to do the same that you. Try casting the connectioneditpart of your created connection and after do yourConnectionEditPart.getPrimaryShape().repaint()

I didn't get yet into the point of creating the connectionEditPart.
My connectionEditPart is created through my CanonicalEditPolicy
but I couldn't find a way to refresh or trigger the CanonicalEdityPolicy once I added semantic elements : so this part of sync between semantic and notational model is missing

Hi,

I had that problem and the only solution I could find was to refresh the entire model:

EditPart mainEditPart = (EditPart)(AnyOfMyEditParts.getRoot().getChildren().get(0));
		 CanonicalEditPolicy cep = (CanonicalEditPolicy)mainEditPart.getEditPolicy(EditPolicyRoles.CANONICAL_ROLE);
		 if (cep!=null)
			 cep.refresh();

This is rather a workaround then a clean solution and it might cause other problems. If you find a better solution please post.

cheers,
emil.

I just called:

CreateConnectionViewAndElementRequest.getCreateCommand ... code

then I added the code you provided:

EditPart mainEditPart = (EditPart)(AnyOfMyEditParts.getRoot().getChildren().get(0));
CanonicalEditPolicy cep = (CanonicalEditPolicy)mainEditPart.getEditPolicy(EditPolicyRo les.CANONICAL_ROLE);
if (cep!=null)
cep.refresh();

And it works.
