    debugging methodology

    rsmithh Newbie

      Can anybody suggest a methodology for debugging internal richfaces exceptions?

       

      Specifically, I'm getting ...

      SEVERE: Servlet.service() for servlet [FacesServlet] in context with path [/tl2010-4] threw exception [null] with root cause

      java.lang.NullPointerException

                at org.richfaces.taglib.ComponentControlHandler.processNextHandler(ComponentControlHandler.java:96)

                at org.richfaces.taglib.ComponentControlHandler.processNestedTags(ComponentControlHandler.java:67)

        .... etc

       

      I'm porting from 3.2->4.2 and haven't yet got it to a state that the page is being displayed. Unfortunately it's a complex page with a large number of components, so I have no simple way to determine which component is causing the error.

       

      I'm hoping that there is a log level I can invoke which will show which xhtml file, component was being processed at the time of the exception.
