----------------------------
Resolution: Fixed
> Struts-Tiles-JSF-Integration SOMETIMES creates blank pages
> ----------------------------------------------------------
>
> Key: STR-2168
> URL: http://issues.apache.org/struts/browse/STR-2168
> Project: Struts Action 1
> Type: Bug
> Components: Faces
> Versions: 1.1 Final
> Environment: Operating System: Windows XP
> Platform: PC
> Reporter: Alexander Manes
> Assignee: David Evans
> Fix For: 1.2 Family
> Attachments: struts-faces-tiles-blank-page-error.zip, struts-faces.fix.jar
>
> I integrated Struts, Tiles and JavaServer Faces in a webapp (development on
> Tomcat 5.0.27, WinXP, j2sdk1.4.2_04).
> Form submissions to struts actions <s:form action="/scrollarticles"> work
> without problems, but the following code sometimes generates blank pages:
> <h:outputLink id="commandLinkPrev" value="scrollarticles.do">
> <f:param name="page" value="#{PrevPage}"/>
> <h:graphicImage url="images/arrow-previous.gif" />
> </h:outputLink>
> When I hit such a link for the first time, it usually works. When I hit
> another one (e.g. with different target) it's likely to fail, but I can hit
> RELOAD and I get a correct response. Usually the next time a similar link
> fails, there's no way to get a response from the server until I reload the
> whole webapp!
> When I get the blank page, there is absolutely no Exception (not on the
> console, not in Tomcat logs, not on the page). The page is just blank!
> Debugging showed that my struts action scrollarticles.do or any other action
> that is called is executed correctly, but no response is rendered to the
> client browser (there is no HTML source that the browser could display, it's
> not just an error in the HTML output).
> Also I get the blank page more often on IE6 than on Opera 7, but both
> browsers
> are configured to load a page upon every single request (not loading from
> local cache).
> Is this a bug or am I totally wrong on the use of h:outputLink???
> I know that s:form logically submits to a struts action, but the rendered
> HTML
> submits to layout.faces because I'm using Tiles. Is it just wrong call a .do
> directly???
