I have a messages.jsp[1] that's included (using <%@(protected)
file="/common/messages.jsp" %>) in my default decorator. This file has a
couple of calls to the valueStack - namely hasActionErrors() and
hasFieldErrors(). This worked fine in WebWork 2.1.x and Struts 2.0.1 - even
when pages where rendered that didn't go through Struts. However, starting
with the 2.0.6 release, the <s:if> tag throws a NPE because the ValueStack
isn't in the request. I believe it's a bug, but wanted to check with this
list first to confirm.

Thanks,

Matt
