Outline problems [message #128042]

Hi!
I am trying to get my outline page to work, but I keep getting an null
argument when the TreeEditPartFactory creates a new
TreeEditPart(AbstractEditPart.addChild()). In my getModelChildren() method
I am using the eContents() to return a list of this Editparts children. I
am using the same design when creating regular EditParts and it works
fine. Hints and thoughts are appriciated.

regards,
Olav
