Description Michael Heinen 2011-12-01 17:26:58 UTC 
I found following exception in the logfile of an automated test.
It happened right after system start when about 10 requests arrived in the same millisecond.

http-8080-7 [ERROR] [D32BD7B2195DF1AAE182A4D24DBE11FF] PhaseListenerManager informPhaseListenersBefore: Exception in PhaseListener RESTORE_VIEW(1) beforePhase.

Tomcat is used in combination with myfaces 1.2.10.
Could this be a threading issue in the CompositeELResolver?
Comment 1 Mark Thomas 2011-12-16 16:08:27 UTC 
CompositeELResolver is not thread-safe during init. It sounds as if MyFaces is trying to configure the same CompositeELResolver instance from multiple threads.
