    it return the existing state of the given URL in the popupmenu of this toolbox control.

    If the given URL can be located as an action command of one menu item of the
    popup menu of this control, we return sal_True. Otherwhise we return sal_False.
    Further we return a fallback URL, in case we have to return sal_False. Because
    the outside code must select a valid item of the popup menu every time ...
    and we define it here. By the way this method was written to handle
    error situations gracefully. E.g. it can be called during creation time
    but then we have no valid menu. For this case we know another fallback URL.
    Then we return the private:factory/ URL of the default factory.

    @param  rPopupMenu
                points to the popup menu, on which item we try to locate the given URL
                Can be NULL! Search will be suppressed then.

    @param  sURL
                the URL for searching

    @param  sFallback
                contains the fallback URL in case we return FALSE
                Must point to valid memory!

    @param  aImage
