objects?

Hello Andreas,

Can you create this multiplt connection using EMF-genersated tree editor?

Hi,

thanks for you hint, but Christian (next Thread) told me, that i have to
create an distinct EClass. I future i have also put values or a value list
(in the property sheet) to this connection.

Hi,

I just tried the hint out what you send to me, but it doesn't work. But
where do you mean to configurate this? in the .gmodel or the .ecore model?

Hello Andreas,

I meant, you can try openning new instance of your domain model using EMF-generated
tree editor and try to create corresponding connections (set reference values)
there. If it is working then the problem is in GMF definition of the connections.
If not - the reason is in EMF model...

Hello Andreas,

Well, using .ecore + .genmodel files you can generate .mode, .edit, .editor
plugins using EMF. These plugins allows you to create new instance of your
model using corresponding wizard + edit it using tree editor. I'm tryinto
to check if the model itself allows this kinf of connections.

Hello Andreas,

> Thanks for your help. It would be great If you can find this out..
I mean, I'm trying to check if the model itself allows this kind of connections
based on your input :-). So, can you create this kind of connections in EMF-generated
editor?

He,

I tried this out. I looked in the editor code and parts of the following
function in the CommandObject

public boolean canExecute() {
if (source == null && target == null) {
return false;
}
return true;
}

But when I close the diagram an reopen it the second connection is missing.
