    Document types inheritance chain with compositions

    Hello, Umbracians

    I have tried to use inheritance to make chain with base class, but I was collided with weird looking behavior.

    So, I wanted to make chain like that:

    SomePage:InnerPage, ISomeCompotion, IOtherBasicComposition

    where :


    That was ok, I have create InnerPage type, then successfully compose it with IBasicComposition and IOtherBasicComposition, then create a child type SomePage. But, when I try to extend the InnerPage with other compositions I force with error message from backoffice: enter image description here

    So, looks like it is not possible, but why in fact it is possible to make it like I do at start?

    The second problem is, looks like there is no way to make an inheritance relation with two existed cocument types. Is it possible somehow?
