>             Project: Struts 2
>          Issue Type: Bug
>          Components: Core Actions
>    Affects Versions: 2.3.1.2

> After upgrading to Struts 2.3.1.2, we get a Nullpointer when trying to access an undefined
action (in example, /badurl.do) - see complete stack below.
> This is because ServletActionContext.getRequest() is NULL when getErrorMessage() gets
called.
> This is a major issue because it prevents 404 error to be handled correctly and it affects
several websites (just Google for "org.apache.struts2.impl.StrutsActionProxy.getErrorMessage(StrutsActionProxy.java:69)")
> Edit: maybe is it due to the fact I'm using deprecated FilterDispatcher...
> java.lang.NullPointerException
