    @short          helper to create new frames by using non special target name and CREATE flag
    @descr          If user whish to find any frame by name or will create it, if it not already exist ...
                    these dispatch helper should be used. Because - a frame must be created at dispatch call ...
                    not on queryDispatch()! So we hold weakreferences to the possible parent frame, safe the name
                    of new frame. If user call dispatch at us - we check a weakreference to our last created frame
                    (he should have same name!) ... if he exist - we do nothing ... if not - we create it again.
                    But if possible parent for new created task doesn't exist - we couldn't do anything!
                    Then we wait for our own dispose and do nothing.

    @attention      Use this class as member only! Never use it as baseclass.
					XInterface will be ambiguous and we hold a weakreference to our OWNER - not to our SUPERCLASS!
