When struts is used to render an error-page, getting the action mapping from
original request
---------------------------------------------------------------------------------------------
Key: WW-3192
URL: https://issues.apache.org/struts/browse/WW-3192
Project: Struts 2
Issue Type: Bug
Components: Dispatch Filter
Affects Versions: 2.1.6
Environment: Tomcat
Reporter: Jasper Rosenberg
Priority: Critical
Fix For: 2.1.8
We have mapped 404 in the web.xml to a struts action, e.g.:
<error-page>
<error-code>404</error-code>
<location>/404.action</location>
</error-page>
Sometimes we have an action return a result type to generate a 404 error. This
used to work. However, now it is failing because
PrepareOperations.findActionMapping() is finding the original mapping still in
the request when the servlet container invokes the 404.action (and so not
getting the struts mapping for the 404 action). I assume this is also a bug
for actions that return a 500 error where the 500 error page is rendered in
struts though I haven't tested it yet.
One fix would be to call request.removeAttribute(STRUTS_ACTION_MAPPING_KEY) at
the end of PrepareOperations.cleanupRequest() though perhaps there are
implications to that I'm unaware of.
