[jira] Commented: (PB-41) Tiles Context gets lost "Struts Bridge - error with tiles"

    [ http://issues.apache.org/jira/browse/PB-41?page=comments#action_12374175 ] 

Ate Douma commented on PB-41:
-----------------------------

James, Max,

Sorry about the late response but I've been very busy otherwise.
I looked at the patch, and while I think its ok, I think this can be solved differently and more generically and it won't need a patch :)

Although I don't have a tiles based StrutsPortlet example to test with (if you could provide me with a simple one, I'd appreciate it)
I think you can have the same effect/solution by defining the following in your WEB-INF/struts-portlet-config.xml:

  <config>
    <render-context>
      <attribute name="org.apache.struts.taglib.tiles.CompContext"/>
    </render-context>
    ...
  </config>

See for a description of this feature of the struts bridge:
  http://portals.apache.org/bridges/multiproject/portals-bridges-struts/features.html#RenderContextAttributes_to_the_rescue

Please let me know if this works!

> There is a bug where the tiles context can get lost, and using tiles in your struts portlet will result in an NPE.
> This happened to me, and after googling the problem, it appears that it had also happened to Max Hammers, who also posted a patch for the error. After searching jira, it apears that this issue is not being tracked yet (so that's why I am opening this one). I manually applied the patch to my copy of the source files (it is very simple), and it works perfectly (thanks Max!).
> So, Ate et al, please apply Max's patch!
