[ http://mc4j.org/jira/browse/STS-326?page=comments#action_10613 ] Tim Fennell commented on STS-326: ---------------------------------
This is really bizarre. In looking at the stack trace and the code, it would appear that the ErrorsTag /is/ getting a reference to a FormTag, which can only happen when it is nested in one (assuming there are no container bugs). But that when it interacts with the FormTag, the FormTag isn't properly setup, and therefore cannot service the request from the ErrorsTag. If you're still experiencing this issue, could you step through with a debugger and see how/where the ErrorsTag is finding a FormTag? > Error and message tags produce null pointer exception on Weblogic 9.2 when > used outside of a form tag. > ------------------------------------------------------------------------------------------------------ > > Key: STS-326 > URL: http://mc4j.org/jira/browse/STS-326 > Project: Stripes > Issue Type: Bug > Components: Tag Library > Affects Versions: Release 1.4.2 > Environment: Weblogic 9.2 on Windows 2003 > Reporter: Karl Kedrovsky > Assigned To: Tim Fennell > > When <stripes:errors /> or <stripes:messages /> tags are places outside of a > <stripes:form> tag stripes produces a null pointer exception.
