Hi,

I am implemeting a small diagram editor and I need to initialize a subdiagram with 2 nodes and a link between them.

Thus I used the "feature seq initilizer" as shown there to create the 2 nodes I need :
************************************************************ **********
-Top node reference <regions:...>
---Node mapping <Region/...>
------Feature Seq Initializer <Region(StateObject)>
---------Reference New Element Spec <stateobjects:=new StateObjects [2]>
-------------Feature Seq Initializer <new Init(Type)>
----------------Feature Value Spec <Type:=...>
-------------------Value Expression InitType::Init
-------------Feature Seq Initializer <new State(Name)>
----------------Feature Value Spec <Name:=...>
-------------------Value Expression 'DefaultStateName'
...
************************************************************ **********
Then I want generate a link (Transition = Polyline connection) between these 2 specific objects.

But I can't find how to make sure the link can be created between these 2. Does anyone have an idea?

Thx
Fab

Hello,

in your xxx.diagram.providers package there must be an
ElemenInitializers class. Locate the method that creates the new link
and modify it accordingly. Do not forget to add the /** @generated NOT
**/ flag so that your changes are not lost when you regenerate the code.

Hope this helps..

thx for this answer Pantelis u were right. Unfortunately I had to find it alone due to eclpse forum troubles. But this is the solution I find.

Just a detail not working. My editor is a diagram. When I add a diagram in it then it should initialise with init->transition->state...but it's not working.

Then I have and object subdiagram to create hierachy in my diagrams. When I add this subdiagram and then double-clic on it, it open a new diagram editor which initialise with the region[init->transition->state]. And that's good Razz

And then when I go back to the first editor, it refresh because the second one change and finally display this missing transition.

Any Idea? The better solution would to initialise the first diagram with a region when it's created (file/newDiagram). But I don't really find how to do it because my Object diagram is also the editor Sad
