Hi,
I found a strange behaviour in one of our pages (facelet).
From time to time there seems to be a state of <tr:outputText>.
I can’t think of a situation where <tr:outputText> should save a state, neither
does Trinidad assume this case.
Therefore there is a ClassCastException thrown on RestoreState.
Our environment is:
Tomcat 6
Myfaces 1.2.3
Trinidad 1.2.10 (SNAP)
Facelets 1.1.14
Any pointers to solve this problem are welcome.
Thanks in advance
Harald
