so basically each time the element changes its bounds?
You can do this in the *EditPolicy of the corresponding element.
Overwrite handleNotification (Notification n).

Write something like this to see if the Bounds (notation model) changed
and update the element:

if (n.getNotifier() instanceof Bounds) {
// you can do additional checks here, e.g. if only its position
// or size changed

YourEObject element = (YourEObject) getPrimaryView().getElement();

element.setName("element" + count);
}

ciao,
elm

You could keep a counter on the class side of the <Element>Impl class then
over ride the create<Element> method (in the FactoryImpl) and set a default.
eg. (in this example I am assuming that incrementCount counter increments
and return the next number).
/**

* 

* 

* @generated NOT

*/

public StartNode createStartNode() {

StartNodeImpl startNode = new StartNodeImpl();

VisualRatingCustomisation.setDefaultTagValueStartNode(startN ode,

StartNodeImpl.TAG_EDEFAULT+StartNodeImpl.incrementCount());

return startNode;

}

Opps I should point out that the class variable might double up when using
mutiple diagrams (not sur what happens at runtime but try it).
If so then get the counter to be a member of your top level diagram item
(the canvas object).
Hope that helps.

Its my Class for my diagram implementation.

I keep all my customisation in a singleton class so I don't lose the code if
I have to delete the project and restart. I just have to remember the
connection points (which I put in comments on the singleton to remind me).
I found this really helpful and not so upsetting when you have to rebuild
from scratch.

hi stu

thanks. I am able to give default name to my diagramelement.

Opps I should point out that the class variable might double up when using
mutiple diagrams (not sur what happens at runtime but try it).
If so then get the counter to be a member of your top level diagram item
(the canvas object).

i dont understand the above mentioned thing that y the class variable
will get doubled.actually its nt getting exactly doubled.But y that is
happening i am not able to understand.

thanks
Varun
