Hi,

I have a Parent class that looks like this (simplified):

class Parent {
name: String;
children[0..1]: Children; <- containament ref.
}

class Children {
name:String;
multiplicity:Int;
}

I generated GMF editor for this ecore model. I want to enable when user click on the Parent in the diagram, that he can change its Children multiplicity property, if Children exists for the Parent. So, I need to show Children multiplicity property in the Parent property sheet. How can I do this? Is it possible to include Children ItemPropertyDescriptors in the Parent ItemPropertyDescriptors ?

thx, Milan

Milan,

Have a look at how TreeNodeItemProvider uses
ItemPropertyDescriptorDecorator to do something similar.
