Hello Fellow Travelers, I think that I have found a problem with tiles in orion. This problem only shows itself when I deploy my web module (war) to my orion server. I do my development in JDeveloper and everything works swimmingly. Also I have the tiles and struts sample applications deployed on the same orion server and they all work perfectly.
I have been banging my head on this for 2 day now and I thought that I'd share my results. When I use the following in my layout.jsp file: <tiles:insert atttribute="foo" ignore="true" /> If I do not pass in the attribute foo, then when the page is displayed all <tiles:....> tags are ignored for the remainder of the page and NO errors are reported. If I leave out the ignore="true" then as expected tiles reports and error on my page. The documentation says that you can use the ignore="true" to have optional tiles. Now when I run the exact same code in JDeveloper everything works as expected. If I don't <put name="foo".../> then all of the attributes that I do <put> get displayed and the missing ones are ignored. Now I also noticed that the phenomina(sp?) is limited only to the actual .jsp page being processed, meaning if you have this happen in a layout_child.jsp that is <put> onto another layout_parent.jsp then the rest of the <tiles:...> in the layout_child.jsp get ignored, but when the engine gets back to the layout_parent.jsp everything works as expected. I know that this all sounds fishy but this behavior is consistant. I am using the same .tld and jar files in my app as are distributed with the tiles sample application. If I am crazy or off base, PLEASE show me the error of my ways and you will have my gratitude. If you do respond, I won't see it until Monday AM Sincerely, Stephen W.
