Hi Stefan, I often got this, if I modified the jsf-file on the server while it is still running. Remove the generated java/class files, then it should work. Otherwise it is somewhere really a bug...

September 2006 16:15 An: MyFaces Discussion Betreff: Problem with duplicated Ids on t:dataScroller component Hi @ all, I'm currently working on the JBoss Portal where i have one portlet in which i want to use the dataScroller from tomahawk. I have real looks great sometimes, but the most time I'm getting one exception (duplicated ids in the faces tree - original part of the exception is at the end of the mail). I have already tried to declare fix ids, but it doesn't matter. my environment: JBoss AS 4.0.4.GA JBoss Portal 2.4 JDK 1.5.0_08 MyFaces 1.1.5-SNAPSHOT Tomahawk 1.1.5-SNAPSHOT Any advice would be helpful ... Thanks, Stefan //ManagedBean public class DummyBean { public Collection<String> getDummyEntries(){ return generateDummyEntries("dummy", 50); } public Collection<String> getOtherDummyEntries(){ return generateDummyEntries("other", 100); } private Collection<String> generateDummyEntries(String prefix, int amount){ Collection<String> col = new Vector<String>(); for(int i=0; i<amount; i++){ col.add(prefix+"_"+i); } return col; } } //JSF Page <%@ page contentType="text/html" isELIgnored="false"%> <%@ taglib uri="http://java.sun.com/jsf/html"; prefix="h"%> <%@ taglib uri="http://java.sun.com/jsf/core"; prefix="f"%> <%@ taglib uri="http://myfaces.apache.org/tomahawk"; prefix="t"%> <f:view> <h:form> <h:panelGrid columns="2"> <t:dataTable id="dummy" rows="10" value="#{dummyBean.dummyEntries}" var="dummyEntry" preserveDataModel="true"> <t:column> <f:facet name="header"> <t:commandSortHeader columnName="name"> <h:outputText value="Dummy" /> </t:commandSortHeader> </f:facet> <h:outputText value="#{dummyEntry}"/> </t:column> </t:dataTable> <t:dataTable id="otherDummy" rows="10" value="#{dummyBean.otherDummyEntries}" var="oDummyEntry" preserveDataModel="true"> <t:column> <f:facet name="header"> <h:outputText value="Other Dummies" /> </f:facet> <h:outputText value="#{oDummyEntry}"/> </t:column> </t:dataTable> <t:dataScroller for="dummy" fastStep="10" pageCountVar="pageCount" pageIndexVar="pageIndex" styleClass="scroller" paginator="true" paginatorMaxPages="9" paginatorTableClass="paginator" paginatorActiveColumnStyle="font-weight:bold;" immediate="true"> <f:facet name="first"> <t:graphicImage url="/images/arrow-first.gif" border="1" alt="first" /> </f:facet> <f:facet name="last"> <t:graphicImage url="/images/arrow-last.gif" border="1" alt="last" /> </f:facet> <f:facet name="previous"> <t:graphicImage url="/images/arrow-previous.gif" border="1" alt="prev" /> </f:facet> <f:facet name="next"> <t:graphicImage url="/images/arrow-next.gif" border="1" alt="next" /> </f:facet> <f:facet name="fastforward"> <t:graphicImage url="/images/arrow-ff.gif" border="1" alt="fastforward" /> </f:facet> <f:facet name="fastrewind"> <t:graphicImage url="/images/arrow-fr.gif" border="1" alt="fastrewind" /> </f:facet> </t:dataScroller> <t:dataScroller for="otherDummy" fastStep="10" pageCountVar="pageCount" pageIndexVar="pageIndex" styleClass="scroller" paginator="true" paginatorMaxPages="9" paginatorTableClass="paginator" paginatorActiveColumnStyle="font-weight:bold;" immediate="true"> <f:facet name="first"> <t:graphicImage url="/images/arrow-first.gif" border="1" alt="first" /> </f:facet> <f:facet name="last"> <t:graphicImage url="/images/arrow-last.gif" border="1" alt="last" /> </f:facet> <f:facet name="previous"> <t:graphicImage url="/images/arrow-previous.gif" border="1" alt="prev" /> </f:facet> <f:facet name="next"> <t:graphicImage url="/images/arrow-next.gif" border="1" alt="next" /> </f:facet> <f:facet name="fastforward"> <t:graphicImage url="/images/arrow-ff.gif" border="1" alt="fastforward" /> </f:facet> <f:facet name="fastrewind"> <t:graphicImage url="/images/arrow-fr.gif" border="1" alt="fastrewind" /> </f:facet> </t:dataScroller> </h:panelGrid> </h:form> </f:view> //Exception org.apache.jasper.JasperException: Client-id : _idJsp9jbp4fc96645first is duplicated in the faces tree.
