Initialize EMF node with default name [message #1052076]

Hi,

I followed this article (http://www.eclipse.org/articles/article.php?file=Article-Integrating-EMF-GMF-Editors/index.html) and integrated EMF and GMF.

I'm wondering if it's possible to define that elements get initially attributes when they are added to the diagram.
For example I'm adding a new child element to my diagram. At the moment all attributes like a name are empty by default.

Are there any places in the code which allows me to define initial attributes?

You can define default values for attributes...

You might specialize the tool that creates them (or the
CreateCreateChildCommand) to initial them with some type of generated
names, but you don't generally do that direct in the model; there you
can only default defaults.

Thanks for your answer Ed.

I assignded an Default Value Literal to my node (see image), but it didn't worked in the selection editor.

index.php/fa/14600/0/

Is it because of the integration of GMF and EMF? Normally it should be working?!
Another problem will be that I use Eugenia for generating my ecore etc. So I think that I have to solve this programmatically. Which class host the CreateCreateChildCommand? Couldn't find it yet.. sry but I'm really new to EMF.

Cheers,
Phil
