Hi everybody,
i have a strange behaviour in my JSF application. For me all works fine
but some customers get a very sporadic EvaluationException during page
rendering (see the stack trace below). Has anybody any pointers for me
how I can fix the trouble or has somebody the same issue?
I'm using:
* MyFaces 1.1.5
* Trinidad 1.0.3 (but IMO it should also happen in newer versions)
* Facelets 1.1.14
* Tomcat 5.5
