Right, my fault, of course this method should return String. My latest try was with String, admittedly. But, somehow, both methods could be invoked without any problems, either the void or the String one. Currently I believe that PPR with Trinidad selectOneChoice leads to this problem. The workaround might be suitable to me, but maybe you are interested in some in-depth solution.
Thank you very much for the help and suggestions, anyway. Frank -----Ursprüngliche Nachricht----- Von: Jozef Dropco [mailto:[email protected]] Gesendet: Mittwoch, 19.
