Error during processing error message - lack of clues/pointers to a cause for
the error
---------------------------------------------------------------------------------------
Key: WICKET-3997
URL: https://issues.apache.org/jira/browse/WICKET-3997
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.5.0
Reporter: Konstantin Ignatyev
I started to see IO exception and then multitude of "Header was already
written" exceptions on a page that displays data table so I suspect that one of
components of item renderer is to blame, however there is NO clue in the stack
what could cause that.
Happening with jetty 7.4.5 and 8.0RC0, 8.0M3, did not try other versions, and I
did not see the exception before, so I suspect some W internals

Application is too big and proprietary to send as test case, sorry. But I
would be happy to place log statements or debug any sections if you point me at
them.
