  1. POJSF Component IDs ignored when dynamically generating Views
    text
    copied!<p>I ran into a bit of a problem. </p> <p>I generate Views dynamically by iterating a list of strings via the c:forEach tag and then including them via the facelets include tag. </p> <p>This works fine for building the layout but shows some strange behaviour. </p> <p>I have a primefaces tabview containing 2 tabs. For the first Tab (the one that gets initially displayed) the component id is set (eg. tabview:categoryTab) but that's not the case for e.g. the second tab, here I only get tabview: for the component id (but it actually should be tabview:usrTab)</p> <p>Why does JSF override the id I set for the second Tab? Am I missing some crucial information from the spec? </p> <p>I use JSF 2 with Primefaces 3.6 (snapshot build) (And yes, I use the snapshot build on purpose and have tested this with stable PF releases as well but the same behaviour occurs)</p> <hr> <p>edit</p> <p>Code: admin.xhtml</p> <pre><code>&lt;ui:composition template="/templates/commonLayout.xhtml"&gt; &lt;ui:define name="content"&gt; &lt;p:panel id="parentPanel"&gt; &lt;h:outputText value="Verwaltung" /&gt; &lt;br /&gt; &lt;p:tabView id="tabview"&gt; &lt;!-- insert marker --&gt; &lt;c:forEach items="#{adminTabs}" var="tab"&gt; &lt;ui:include src="#{tab}" /&gt; &lt;/c:forEach&gt; &lt;/p:tabView&gt; &lt;/p:panel&gt; &lt;/ui:define&gt; &lt;/ui:composition&gt; </code></pre> <p>catTab.xhtml</p> <pre><code>&lt;ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:p="http://primefaces.org/ui" xmlns:ui="http://java.sun.com/jsf/facelets"&gt; &lt;p:tab title="Categories Tab" id="catTab"&gt; .... &lt;/p:tab&gt; &lt;/ui:composition&gt; </code></pre> <p>usrTab.xhtml</p> <pre><code>&lt;ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:p="http://primefaces.org/ui" xmlns:ui="http://java.sun.com/jsf/facelets"&gt; &lt;p:tab title="Users Tab" id="usrTab"&gt; .... &lt;/p:tab&gt; &lt;/ui:composition&gt; </code></pre> <p>testTab.xhtml</p> <pre><code>&lt;ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:p="http://primefaces.org/ui" xmlns:ui="http://java.sun.com/jsf/facelets"&gt; &lt;p:tab title="TestTab" id="testTab"&gt; .... &lt;/p:tab&gt; &lt;/ui:composition&gt; </code></pre> <p>ContentProvider.java</p> <pre><code> public class ContentProvider { .... @Produces @Named("adminTabs") public List&lt;String&gt; getTabs(){ List&lt;String&gt; components = new ArrayList&lt;String&gt;(); components.add("/templates/tabs/catTab.xhtml"); components.add("/templates/tabs/usrTab.xhtml"); components.add("/templates/tabs/testTab.xhtml"); return components; } .... } </code></pre> <p>This gets generated:</p> <pre><code>&lt;ul class="ui-tabs-nav ui-helper-reset ui-helper-clearfix ui-widget-header ui-corner-all" role="tablist"&gt; &lt;li class="ui-state-default ui-tabs-selected ui-state-active ui-corner-top" aria-expanded="true" role="tab"&gt; &lt;a href="#tabview:catTab"&gt;Categories&lt;/a&gt; &lt;/li&gt; &lt;li class="ui-state-default ui-corner-top" aria-expanded="false" role="tab"&gt; &lt;a href="#tabview:j_idt31"&gt;TestTab&lt;/a&gt; &lt;/li&gt; &lt;li class="ui-state-default ui-corner-top" aria-expanded="false" role="tab"&gt; &lt;a href="#tabview:j_idt32"&gt;Benutzer und Rollen&lt;/a&gt; &lt;/li&gt; &lt;/ul&gt; </code></pre> <p>So, to reiterate: Only the id for the first tab is retained, the ids for the other tabs are generated despite being set in the xhtml code... </p>
