True. But why does myComp not support the XStorable, although it is the same document with the same URL? > I know much about UNO technology in general, but little about the > specifics of the OOo API, so I have no idea whether this.xComponent and > ((XModel)this.xComponent).getCurrentController() should reference the > same UNO object. I saw Mathias Bauer (who does know all the specifics > of the OOo API) already answer on this thread, maybe you should re-read > his post. I read his answer carefully and it helped me to solve my problem with the code. But I don't understand why there is a difference between the this.xComponent and myComp. Maybe Mathias can answer me.
