Issue of Parent child Realtionship [message #210362]

There is a parent , that has got only one child .
And that child has got many childrens.
The return type of getModelChildren() is List. But the return type in the
model is the object of the child itself i.e. getTree() which returns Tree,
not EList Type.

What i have done in create command i have created an object of
EObjectContainmentList() and provided the values, but this also doesnt
works.

How to go about it?

Thanks
Gaurav

This all depends how you visualize your model. If you visualize the "Tree"
as a single item, then it would be contained as single item in the List .
Otherwise, you would need to consolidate or wrap your model to conform to
the GEF api.

There are number of examples of the getModelChildren api implementation:
org.eclipse.gef.examples.ediagram.outline#ClassifierTreeEdit Part
org.eclipse.gef.internal.ui.palette.editparts#PaletteEditPar t
