Using the emf editor, I have an emf instance tree with a property sheet. For a certain emf type, I have properties in the properties sheet. One of these properties is a list of other emf types.
By default the property sheet "tries" to display all reachable objects of this type. Now I want to display just a subset of all reachable types. I thought I may be able to the filterFlags upon calling "createItemPropertyDescriptor", but I am not rally sure if this is the right way. (Moreover, i don't find any docu an allowed values for filterFlags.)
Can u give me a hint towards the right direction?
Thank you very much for any help!
Cheers,
Christoph

Christoph,

Have a look at how EReferenceItemProvider.addEOppositePropertyDescriptor
specializes getChoiceOfValues.
