Java.lang.IllegalStateException: duplicate Id for a component

Question

Hi everyone,
please I'm really having a serious issue on the duplicate id for a component in view.
I have a page of which I used the <jsp:include> tag to add to some pages of my application.
The page have the following code snippet in it
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<%@taglib prefix="a4j" uri="http://richfaces.org/a4j"%>
<%@taglib prefix="rich" uri="http://richfaces.org/rich"%>
<f:subview id="footerView">
      <table width="80%" border="0" align="center" cellpadding="0" cellspacing="1">
      <tr>
          <td>
               <h:outputLink id="homeLink" value="#{facesContext.externalContext.requestContextPath}/index.jsf"
                             rendered="#{facesContext.viewRoot.viewId != '/index.jsp'}">                                                  
                    <h:outputText value="Home |"/>                              
                </h:outputLink>
          </td>
         </tr>
      </table>
</f:subview>The problem is that I always get this exception :
    java.lang.IllegalStateException: duplicate Id for a component footerView:homeLink
     org.ajax4jsf.application.AjaxStateManager$TreeStrutureNode.apply(AjaxStateManager.java:326)
     org.ajax4jsf.application.AjaxStateManager$TreeStrutureNode.apply(AjaxStateManager.java:348)
     org.ajax4jsf.application.AjaxStateManager$TreeStrutureNode.apply(AjaxStateManager.java:348)
     org.ajax4jsf.application.AjaxStateManager.saveSerializedView(AjaxStateManager.java:236)
        .........This exception always occurs whenever I tried invoking an action or event call in like the ones listed
below in any of the enclosing page..
<h:selectOneRadio immediate="true" required="true" id="optionsRadio" value="#{myBean.optionType}" layout="lineDirection"valueChangeListener="#{eventBean.updateOptionTypeEvent}">                                        
     <f:selectItems value="#{listManagerBean.staticListDataMap['OPTION_TYPE']}"/>
     <a4j:support ajaxSingle="true" ignoreDupResponses="true" immediate="true" event="onblur"/>                         
</h:selectOneRadio>
OR
<a4j:commandButton type="submit" value="Submit Now!" action="#{bean.someAction}"/>
      <h:commandButton type="submit" value="Click Me"/>Yet there is no other component in view with the said id "footerView:homeLink".
So I'm really at a loss on what to do.
Any help will be greatly appreciated.

Hi, I have the same issue.
In my case I have a page that includes one page with richfaces components and if another link is clicked, it includes anotherone without richfaces.
But both included pages contain some identical subpages.
Everytime I call the page with the richfaces components and then the other one I get
java.lang.IllegalStateException: duplicate Id for a component webSourceSetupForm:executionTab:executionTable:executionDayList
     org.ajax4jsf.application.AjaxStateManager$TreeStrutureNode.apply(AjaxStateManager.java:442)
     org.ajax4jsf.application.AjaxStateManager$TreeStrutureNode.apply(AjaxStateManager.java:464)This worked fine before I added richfaces....
The id is even different in both cases. in on it is webSourceSetupForm:executionTab:executionTable:executionDayList in the other jdbcSourceSetupForm:executionTab:executionTable:executionDayList
Did you find a solution to the problem?
Anyone has any idea?
Thank you,
Mathis
