Hallo zusammen,

im Container des WAS 6.1 befindet sich eine Implementierung von JSF 1.1, was lediglich die Verwendung von MyFaces 1.1 zulässt. Ich habe es nun über den Classloader geschafft MyFaces 1.2 zu verwenden. Manche Seiten funktionieren auch, aber an manchen Stellen bekomme ich folgende Exception:

Code :

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

Da manche Seiten funktionieren gehe ich an dieser Stelle einfach mal davon aus, dass es sich um Tags innerhalb der nicht funktionierenden Seiten handelt, die dieses Problem auslösen. Hat jmd. noch 'ne andere Idee, kennt dieses Phänomen jmd., bin ich total auf dem Holzweg?

Vielen Dank für Eure Antworten im Voraus.
