[jboss-user] [JBoss Seam] - Using the pages.xml to pass a parameter

Hi, I'm trying to understand how the pages.xml file is used to pass a parameter. I have the following in my pages.xml file | <pages> | <page view-id="/centerdetail.xhtml" action="#{centerSearch.performSearch(center.centerID)}"> | <param name="selectedCenter" value="#{center.centerID}"/> | </page> | </pages> | the code in the page that request the centerdetail.xhtml page is | <h:panelGroup id="centerResultsPanel" rendered="#{basicSearch.researchCenterSearch}"> | <h:dataTable id="researchcenterResults" var="center" value="#{searchResultList}" rendered="#{searchResultList.rowCount >0}"> | <h:column> | <h:outputLink> | <h:graphicImage url="images/logotype.gif"/> | <h:outputText value="#{center.centerID}"/> | <h:outputText value="#{obj.centerID}"/> | </h:outputLink> | </h:column> | <h:column> | <h:panelGrid id="holder" > | <s:link id="centerName" view="/centerdetail.seam" action="#{centerSearch.performSearch(center)}" value="#{center.displayName}"/> | <h:outputFormat value="#{center.description}"/> | </h:panelGrid> | </h:column> | </h:dataTable> | <h:outputText value="#{messages.zeroresults}" rendered="#{searchResultList.rowCount==0 and basicSearch.researchCenterSearch}" /> | </h:panelGroup> | and this performSearch method in my centerSearch bean is as follows | @SuppressWarnings("unchecked") | public String performSearch(ResearchCenter id) { | Query query; | log.debug(" Searching for center by ID "); | log.debug("Center ID: #0", id); | | return "success"; | } | The center id is being appended to the url but is showing up as null in the server.log file 2006-12-21 14:29:16,468 DEBUG [gov.nih.nci.cagrid.portal.command.CenterSearchBean] Center ID:null Does anyone know how to pass an object from a selected row in a datatable to a separate bean , ie my searchBean holds the following | @DataModel("searchResultList") | protected List<? extends DomainObject> results; | | @DataModelSelection() | protected DomainObject domainObj; | and I want to pass the object of the selected row to a centerBean. Any suggestions would be greatly appreciated. Thank you View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3995708#...
