Hi Martin! Thank you first for your time and interest. - Yes, the commandLink is not firing it's action-listener. - I am not sure if I am using a dataModel over requests. I did not consider that detail. If it clears things out, would you mind to elaborate about his point?
On the bottom is the page I am working with. It has been taken 1:1 out of the book "JSF in Action" as are their backing bean classes and other stuff. (But when I encountered this problem, I snipped away 4 not necessary columns to isolate the problem.) The author says he has been working with SUN JSF-RI. showAllBean is a request-scoped bean that is displaying a page with tabular output-only information about projects. In each column header is a "sort" link which orders the projects by e.g. name. The showAllBean is designed to be stateless, therefore it is request-scoped and to be recreated on each request-response cycle.(BTW it is backed by a facade-like referenced-bean that talks to business objects) The rendered "sort" link is not submitting the form, as intended, but just forwards to the input page again, transmitting some generated "_id1:_link_hidden_=id1:_id5:name" request values. Please note again that the form is not submitted by this link e.g. via javascript, it's the as-is default behaviour of HtmlCommandLink. Next I describe the observed essential behaviours by following the inbound path from the browser: - The view is restored including the action-listener. That is, it's method binding is attached to the UICommand's _actionListener variable.(UICommand class, restoreState method) - Afterwards in the ApplyRequestValues Phase, on decoding the tree outer-to inner element, the HTMLFormRenderer gets it's turn. Code Lines 15o to 152 say : if no "submitted" value found, set the state isSubmitted to false, which is as expected. - But then the thread returns to UIForm which in processDecodes code line 42 says: I am not submitted, so I return immediately from decoding. All it's childOrFacet components are __NOT__ decoded, as is my link that is contained in it's header. Hence the link's action-listener is not put on the event-queue and hence my bean is never called. This is the bottom-line of my post. I hope that this description does make more sense to you. Thanks a lot. Jörg P.S. Do you think the restored method binding of the action listener is still related to the showAllBean from the outbound response or to the newly created showAllBean upon the inbound request? <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <%@ taglib uri="http://java.sun.com/jsf/core"; prefix="f"%> <%@ taglib uri="http://java.sun.com/jsf/html"; prefix="h" %> <f:view> <html> <head> <title> <h:outputText value="ProjectTrack - Show all projects"/> </title> <link rel="stylesheet" type="text/css" href="<%= request.getContextPath() %>/stylesheet.css"/> </head> <body class="page-background"> <h:form> <h:panelGrid headerClass="page-header" styleClass="table-background" columns="1" cellpadding="5"> <%-- Header --%> <f:facet name="header"> <h:outputText value="Show all projects"/> </f:facet> <%-- Panel data --%> <h:messages globalOnly="true" styleClass="errors"/> <!> <h:dataTable styleClass="table-background" rowClasses="table-odd-row,table-even-row" cellpadding="3" value="#{showAllBean.allProjects}" var="project" binding="#{showAllBean.projectTable}"> <h:column> <f:facet name="header"> <h:commandLink styleClass="table-header" id="name" actionListener="#{showAllBean.sort}"> <h:outputText value="Project name"/> </h:commandLink> </f:facet> <h:outputText value="#{project.name}"/> </h:column> </h:dataTable> </h:panelGrid> </h:form> </body> </html> </f:view> -----Ursprüngliche Nachricht----- Von: Martin Marinschek [mailto:[EMAIL PROTECTED] Gesendet: Mittwoch, 1.
