Hi there,
i need some help with that. I want to create a child object (view and
model element) when the creation of my parent is completed.
In detail i want that a special attribute (in my case EjbAttribute) is
created when the user adds a class (in my case EjbClass).
EjbClass has a reference (named attribute) to infinit EjbAttribute's.
I tried to use the informations about ICommand and so on i found in the
news and wikis, but i'm stuck.
What's the intended way to do that what i want to do? I think i only
need a hint where i have to start ...
regards
jens

That was a good advice, thanks.
Now i need to create another element on parent creation, but this time i
have to position the inner elements to special positions. With the
feature initializer that isn't possible, so i have to create and
position the graphical elements programmatically.
Do you have hints for that too?
