Exception on WOComponentRequestHandler - nullPointerException

Exception on WOComponentRequestHandler - nullPointerException

  • Subject: Exception on WOComponentRequestHandler - nullPointerException
  • From: "Jonathan Fleming" <email@hidden>

After having done a search and getting my results back in batched groups through a generic displayGroup I sometimes come across a timeout problem when navigating through the next or previous batches, however, the log takes a long while (5-10 mins) to spew out its details of the problem shown below.
Can anyone give me a little more idea of where to or how to capture such an exception? Seems like this private Class is not covered in the API.

Advanced Thanks
Jonathan :^)
