Hi folks, I am using Tiles with Struts 1.2.9. I have a 'standard' JSP defining the global layout used by all pages, as in the snippets below:
##### * File: /WEB-INF/tiles-defs.xml <tiles-definitions> <definition name="standard" path="/WEB-INF/tiles/standard.jsp"> <put name="jsphead" content="/WEB-INF/tiles/standard/jsphead.jsp"/> <put name="htmlhead" content="/WEB-INF/tiles/standard/htmlhead.jsp"/> <put name="title" content="/WEB-INF/tiles/standard/title.jsp"/> <put name="content" content="/WEB-INF/tiles/standard/content.jsp"/> <put name="footer" content="/WEB-INF/tiles/standard/footer.jsp"/> </definition> <definition name="default" extends="standard"> <put name="content" content="/WEB-INF/tiles/default/content.jsp"/> </definition> <!-- Other definitions extending standard... --> </tiles-definition> ##### * File: /WEB-INF/tiles/standard.jsp <?xml version="1.0" encoding="UTF-8"?> <jsp:root version=" 1.2" xmlns="http://www.w3.org/1999/xhtml"; xmlns:jsp="http://java.sun.com/JSP/Page"; xmlns:html="/tags/struts-html" xmlns:bean="/tags/struts-bean" xmlns:tiles="/tags/struts-tiles"> <tiles:insert attribute="jsphead" /> <html:html xhtml="false"> <tiles:insert attribute="htmlhead" /> <body> <tiles:insert attribute="title" /> <tiles:insert attribute="content" /> <tiles:insert attribute="footer" /> </body> </html:html> </jsp:root> ##### Now, I would like to have a definition that extends 'standard' while defining new entry points. I have tried using the following approach: ##### * File: /WEB-INF/tiles-defs.xml <definition name="multiPane" extends="standard"> <put name="content" content="/WEB-INF/tiles/multiPane/content.jsp"/> <putList name="pgList"> <add value="/WEB-INF/tiles/multiPane/blank.jsp"/> </putList> </definition> <definition name="test" extends="multiPane"> <putList name="pgList"> <add value="/WEB-INF/tiles/test/page1.jsp"/> <add value="/WEB-INF/tiles/test/page2.jsp"/> </putList> </definition> File: /WEB-INF/tiles/multiPane/content.jsp <?xml version="1.0" encoding="UTF-8"?> <jsp:root version="1.2" xmlns="http://www.w3.org/1999/xhtml"; xmlns:jsp="http://java.sun.com/JSP/Page"; xmlns:html="/tags/struts-html" xmlns:tiles="/tags/struts-tiles" xmlns:logic="/tags/struts-logic" xmlns:bean="/tags/struts-bean"> <html:xhtml/> <div id="content"> <tiles:useAttribute name="pgList" id="pgList" classname="java.util.List"/> <logic:iterate name="pgList" id="pg"> <tiles:insert flush="false"> <jsp:attribute name="page"><bean:write name="pg"/></jsp:attribute> </tiles:insert> </logic:iterate> </div> </jsp:root> ##### * File: /test/index.jsp <%@ page contentType="text/html" pageEncoding="UTF-8" %> <%@ taglib prefix="tiles" uri="/tags/struts-tiles" %> <tiles:insert definition="test"/> ##### In my understanding of how Tiles work, this should insert into the index.jsp page the result of the evaluation of content.jsp, iterating through the list provided in the tiles-defs.xml to output each tab's content. However, when running the above code, I end up with the following trace: ##### javax.servlet.jsp.JspException: Error - tag useAttribute : attribute 'pgList' not found in context. Check tag syntax at org.apache.struts.taglib.tiles.UseAttributeTag.doStartTag(UseAttributeTag.java:182) at org.apache.jsp.WEB_002dINF.tiles.multiPane.content_jsp._jspService(content_jsp.java:83) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:334) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) ... ##### What am I doing wrong here ? Is there a way to get this working ? For the moment, the only way I have to get the expected result, is having every page define the raw list in its 'content' tile using <tiles:insert page="..."/> , which induces heavily duplicated code. Thanks in advance, J.B Lièvremont
