Hi,
Last month i've upgraded our internally used website from Tap 5.1 to 5.2.4,
all went well until i found this disturbing exception in the error log:
ERROR 2011-02-03 17:42:56,303 [TP-Processor7][]
org.apache.tapestry5.services.TapestryModule.RequestExceptionHandler -

I have however no clue as who clicked what and where but this seems like
some sort of bug in the new none-pooling page implementation ?
Best regards,
Antal
