Re: Problem creating Facelet component using Trinidad

ui:repeat is a component - not just a tag.  And
you can only use commandNavigationItems as
direct children of navigationPane.

Your choices:

- Use c:forEach instead of ui:repeat
- Use the built-in iteration in navigationPane:

             <tr:navigationPane hint="tabs" value="#{tabs}" var="tab">
                 <f:facet name="nodeStamp">
                    <tr:commandNavigationItem
                        text="#{tab.label}"
                        selected="#{ tab.selected}"
                        partialSubmit="true"/>

                 </f:facet>
             </tr:navigationPane>

A word of caution on the latter...  it didn't work until
issue ADFFACES-275 was fixed, which was fixed as of two
minutes ago. :)

I am trying to create a component using Facelet Tags. The component uses a Trinidad NavigationPane (tr:NavigationPane). I am trying to make this component reusable by passing a collection of "options" to it. Each option represents a commandNavigationItem 

Here is the component

<!--facelets/components/tabNavigation.xhtml-->

<div
    xmlns="http://www.w3.org/1999/xhtml";
    xmlns:f=" http://java.sun.com/jsf/core";
    xmlns:ui="http://java.sun.com/jsf/facelets";
    xmlns:tr=" http://myfaces.apache.org/trinidad";>
<tr:form> 
         <tr:panelGroupLayout layout="horizontal">
             <tr:navigationPane hint="tabs">
                 <ui:repeat value="#{tabs}" var="tab">
<tr:commandNavigationItem text="#{tab.label}" 
                        selected="#{ tab.selected}"
                        partialSubmit="true"/>
</ui:repeat> 
             </tr:navigationPane>
         </tr:panelGroupLayout>
     </tr:form>
</div>

Here is my usage

<stl:tabNavigation
    tabs="#{AddressLookupBacking.tabOptions}"
    bean="#{AddressLookupBacking}"/>

I am initializing the tabOptions list in Faces-Config

Here is the tab lib
<facelet-taglib>
    <namespace>http://stlouiscity.com/jsf/csb</namespace>
    <tag>
        <tag-name>tabNavigation</tag-name>
        <source>facelets/components/tabNavigation.xhtml</source>
    </tag>
</facelet-taglib>

Here is my problem

It seems that Trinidad is getting hung up on the ui:repeat facelet tag. I am just learning both Facelets and Trinidad so any help would be greatly appreciated. 

I have posted this both the the Facelets and Trinidad User Lists
