Is this possible? rich:panelMenuItem in a4j:repeat

[chamika]

Hi all
I'm trying to repeat rich:panelMenuItems using a4j:repeat.
This is my code

<rich:panelMenu>
 <rich:panelMenuGroup label="Roles">
 <a4j:repeat value="#{ApplicationBean1.roles}" var="item">
 <rich:panelMenuItem label="#{item.description}" >
 <f:param name="current" value="#{item.description}"/>
 </rich:panelMenuItem>
 </a4j:repeat>
 </rich:panelMenuGroup>
 </rich:panelMenu>

When run it there is an error saying
java.lang.ClassCastException: org.ajax4jsf.component.html.HtmlAjaxRepeat

But when I put it like below(put a4j:repeat outside) it works, but instead of generating panelMenuItem it repeats panelMenus. How do I solve this problem. Plase help me.

<a4j:repeat value="#{ApplicationBean1.roles}" var="item">
 <rich:panelMenu>
 <rich:panelMenuGroup label="Roles">
 <rich:panelMenuItem label="#{item.description}" >
 <f:param name="current" value="#{item.description}"/>
 </rich:panelMenuItem>
 </rich:panelMenuGroup>
 </rich:panelMenu>
 </a4j:repeat>

a4j:repeat component is not in the list if valid children for panelMenuGroup. Use c:forEach or create menu from the Java code

Thank u very much for ur reply. My problem solved by you.
This is the working code

<jsp:root version="2.1" xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:webuijsf="http://www.sun.com/webui/webuijsf"

 <webuijsf:page id="page1">
 <webuijsf:html id="html1">

 </webuijsf:head>
 <webuijsf:body id="body1" style="-rave-layout: grid">
 <webuijsf:form id="form1">
 <rich:panelMenu groupStyle="z-index:3000;" iconCollapsedGroup="disc" iconCollapsedTopGroup="chevronDown" iconExpandedGroup="disc"
 iconExpandedTopGroup="chevronUp" iconGroupTopPosition="right" mode="ajax" style="width:300px">
 <rich:panelMenuGroup label="User Roles">
 <c:forEach var="urole" items="#{ApplicationBean1.roles}" >
 <rich:panelMenuItem label="#{urole.description}">
 <f:param name="current" value="#{urole.code}" />
 </rich:panelMenuItem>
 </c:forEach>
 </rich:panelMenuGroup>
 </rich:panelMenu>
 </webuijsf:form>
 </webuijsf:body>
 </webuijsf:html>
 </webuijsf:page>
 </f:view>
</jsp:root>

Thanx again

hiya,

I try to build a dynamic panelMenu. I don't want to bind the whole panelMenu in a backing bean, because I have to do some rerendering during the apllication is running.
So I also build an iterative panelMenu with <c:forEach>. But somehow it doesn't work.
Here's the code

<rich:panelMenu width="200px" mode="ajax"
 iconExpandedGroup="disc" iconCollapsedGroup="disc"
 iconExpandedTopGroup="chevronUp" iconGroupTopPosition="right"
 iconCollapsedTopGroup="chevronDown">
 <rich:panelMenuGroup label="test">
 <c:forEach items="#{menuGroup.menuItems}" var="item">
 <rich:panelMenuItem label="#{item.title}" action="#{item.url}"/>
 </c:forEach>
 </rich:panelMenuGroup>
</rich:panelMenu>

I only get the panelMenuGroup with the label 'test', but there are no items in the panelMenuGroup. the list menuItems is not empty. Is it right, that the c:forEach doesn't use setters and getters?
Can somebody give me any suggestions?

thx,
traysa

I'm not much sure about the solution. But try to change "menuGroup" beans scope to session and make sure the "menuItems" getters and setters are correctly set.

Do you use Facelets or JSP? What is URI for c:* prefix?

Same problem in RF-3.1.4, upgrade to RF-3.2.2 is okay.

[traysa]

Thanks for the reply :)

@chamika: I tried your suggestion, but it take no effect.

@nbelaevski: I'm using JSP. The URI for c prefix is http://java.sun.com/jsp/jstl/core.

@realsantino: I'm using RF-3.2 and just updated to RF-3.3.


I changed

<c:forEach items="#{menuGroup.menuItems}" var="item">

to

<c:forEach items="${menuGroup.menuItems}" var="item">

Now I have the right number of menuGroups, but the label aren't printed
(<rich:panelMenuItem label="#{item.title}" .../>).

thx,
traysa

Have u tried it with using value instead of label?
Because I have done the exact thing with using rich:menuItem and it has only the "value" attribute and rich:panelMenuItem also has the "value" attribute.

This is the code

<h:form>
 <rich:toolBar>
 <rich:dropDownMenu>
 <f:facet name="label">
 <h:panelGroup>
 <h:graphicImage value="#{pageContext.request.contextPath}/resources/images/blinklist.png" styleClass="pic"/>
 <h:outputText value="User Roles"/>
 </h:panelGroup>
 </f:facet>
 <c:forEach var="urole" items="#{SessionDetails.user.roles}" >
 <rich:menuItem submitMode="server" value="#{urole.description}" icon="#{pageContext.request.contextPath}/resources/images/vista_xp.gif"
 action="#{MainPage.printPara}" >
 <f:param name="sendUrl" value="#{urole.pageUrl}" />
 </rich:menuItem>
 </c:forEach>
 </rich:dropDownMenu>
 </rich:toolBar>
</h:form>

[traysa]

change of label to value has no effect :(
thx

[nbelaevski]

Traysa,

My suggestion why that is happening is that you are using JSP 2.0 version of JSTL and not JSP 2.1. Please check what JSP version is declared in c.tld file.

[mehdibr]

Hello !

I got the same problem and I haven't found any solution.

About the JSP version of JSTL, Here is the begining of my c.tld

<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
 version="2.0">

 <description>JSTL 1.1 core library</description>
 <display-name>JSTL core</display-name>
 <tlib-version>1.1</tlib-version>
 <short-name>c</short-name>
 <uri>http://java.sun.com/jsp/jstl/core</uri>

So this si the the JSP 2.0 version of JSTL ? Where can I find the the 2.1 and how to install it ?

Thanks a lot!

[nbelaevski]

Check appserv-jstl.jar in Glassfish distribution.

[mehdibr]

I finally found the problem : the address in the statement was wrong :

This is the right statement
xmlns:c="http://java.sun.com/jstl/core"
