Occasionally when rolling out pages via the Sidekick our content authors will receive a notification that the Rollout failed. This notification has no information indicating what the cause of the failure actually was. Digging through the error logs the only item that pops up is the following:
29.01.2013 17:59:08.939 *ERROR* [10.7.202.40  POST /bin/wcmcommand HTTP/1.1] com.day.cq.wcm.msm.impl.commands.RolloutCommand Error during rollout. java.lang.NullPointerException
There is no Stack Trace accompanying the error though. Any ideas what could be causing the Null Pointer? If we delete the Live Copy and create a new one the issue does not occur, at least not immediately. My assumption is that the Blueprint page is changing too much between rollouts, resulting in the LiveSync not functioning correctly. I could be completely wrong with that though.
Any suggestions or direction would be much appreciated.
It should display more stack trace & but not sure what is happening. Verify the rollout configs on blue prints & new sites.
