> Environment: Struts 2.0.11.1, Tiles 2.0.6, Tiles Plugin 2.0.11.1
> Reporter: Sridhar Reddy T
> Fix For: Future

> Attachments: StrutsTilesRequestContext.java

> When i try to use Tiles in Portlet environment using the above versions, it
> does not work. I have done some research and these are my findings.
> ( Step 1) CODE BASE - TILES PLUGIN 2.0.11.1
> In org.apache.struts2.tiles.StrutsTilesRequestContext, this logic is such
> that it always calls dispatch(), if mask is not ending with ".ftl".
> public void dispatch(String include) throws IOException {
> if (include.endsWith(mask)) {
> // FIXME This way FreeMarker results still don't have a
> content-type!
> include(include);
> } else {
> super.dispatch(include);
> }
> }
> ( Step 2) CODE BASE - TILES 2.0.6
> super.dispatch() in the above code calls
> org.apache.tiles.servlet.context.ServletTilesRequestContext.dispatch()
> public void dispatch(String path) throws IOException {
> if (response.isCommitted() || ServletUtil.isForceInclude(request)) {
> include(path);
> } else {
> forward(path);
> }
> }
> Atleast above logic should have worked to call include(), if
> ServletUtil.isForceInclude(request) returned true.
> ServletUtil.isForceInclude(request) returns true if
> request.getAttribute(ServletUtil.FORCE_INCLUDE_ATTRIBUTE_NAME) = =true.
> ( Step 3) CODE BASE - STRUTS 2.0.11.1
> Call to
> org.apache.struts2.portlet.servlet.PortletServletRequestDispatcher.doForward()
> throws IllegalStateException.
> public void forward(ServletRequest request, ServletResponse response)
> throws ServletException, IOException {
> throw new IllegalStateException("Not allowed in a portlet");
>
> }
> My guess is, forward() should not be called when the result is of type
> TilesResult.
> My guess is that we need a fix in Step 1.
> EITHER
> call super.include() instead of calling dispatch()
> OR
>
> request.setAttribute("org.apache.tiles.servlet.context.ServletTilesRequestContext.FORCE_INCLUDE",
> new Boolean(true)) before calling super.dispatch().
> Thanks,
> Sridhar.
