NullPointerException instead of "There is no Action mapped for namespace..."
(regression?)
------------------------------------------------------------------------------------------
Key: WW-3770
URL: https://issues.apache.org/jira/browse/WW-3770
Project: Struts 2
Issue Type: Bug
Components: Core Actions
Affects Versions: 2.3.1.2
Reporter: Antoine W
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)")
java.lang.NullPointerException
