Use Panelmenu

[kofa72]

Hi,

For my Navigation in my Webapp i try to use the panelmenu source code where i have found of the richFaces Website (http://livedemo.exadel.com/richfaces-demo/richfaces/panelMenu.jsf).

The problem is that i want build the panelMenuItem dynamically.
Therefore i tried with a datalist to iterate my list over the panelMenuItem.

<h:panelGrid columns="2" columnClasses="cols" width="100%">
 <rich:panelMenu style="width:200px" mode="ajax"
 iconExpandedGroup="disc" iconCollapsedGroup="disc"
 iconGroupTopPosition="right"
 iconCollapsedTopPosition="right" >
 <rich:panelMenuGroup label="Products">
 <rich:dataList rows="10"
 value="#{testBean.products}"
 var="prod" >
 <h:column>
 <rich:panelMenuItem id="pk"
 actionListener="#{testBean.show}">
 <h:outputText value="#{prod.name}" />
 <f:attribute name="productkat" value="#{prod}" />
 </rich:panelMenuItem>
 </h:column>
 </rich:dataList >
 </rich:panelMenuGroup>
 </rich:panelMenu>
 </h:panelGrid>

I receive then the following error:
'javax.faces.component.UIColumn'

Has anyone an idea to solve this problem?

Thanks in advance for your help.

Use c:forEach insteed of rich:dataList

Hy!

I have done it this way (build the whole panelMenu dynamically):

in my jsp-site:

<rich:panelMenu binding="#{navigationMenu.panelMenu}" width="220" />

and in my managed Bean:

HtmlPanelMenu panelMenu = null;

public HtmlPanelMenu getPanelMenu()
 {
 if(panelMenu == null)
 {
 panelMenu = new HtmlPanelMenu();

 FacesContext facesContext = FacesContext.getCurrentInstance();
 Application appl = facesContext.getApplication();
 ELContext elContext = facesContext.getELContext();
 ExpressionFactory exprFactory = appl.getExpressionFactory();

 HtmlPanelMenuGroup menuGroup_AccountInfo = new HtmlPanelMenuGroup();
 menuGroup_AccountInfo.setLabel(myGuiUtil.getMessageResource("menugroup_account"));
 menuGroup_AccountInfo.setName(myGuiUtil.getMessageResource("menugroup_account"));
 menuGroup_AccountInfo.setIconCollapsed("triangle");
 menuGroup_AccountInfo.setIconExpanded("triangleDown");

 HtmlPanelMenuItem menuItem_AccountInfo = new HtmlPanelMenuItem();
 menuItem_AccountInfo.setLabel(myGuiUtil.getMessageResource("menugroup_account_products"));
 menuItem_AccountInfo.setName(myGuiUtil.getMessageResource("menugroup_account_products"));
 menuItem_AccountInfo.setActionExpression(exprFactory.createMethodExpression(elContext, "navigate_accountinfo", null, new Class[0]));

 menuGroup_AccountInfo.getChildren().add(menuItem_AccountInfo);

 panelMenu.getChildren().add(menuGroup_AccountInfo);

 .............
 }

 return panelMenu;
 }

It works now, i could solve it with the c:forEach solution.

Many thanks at both for helping.
