For RichFaces 4 M5, I try to wrap rich:popupPanel component as composite component so I can reuse the header control across the application. The code is shown below:

<cc:interface>

    <cc:attribute name="header" required="true" />

    <cc:attribute name="width" default="550" />

    <cc:attribute name="height" default="550" />

</cc:interface>

<cc:implementation>

    <rich:popupPanel

        id="#{cc.clientId}"

        modal="false"

        resizable="true"

        autosized="true"

        width="#{cc.attrs.width}"

        height="#{cc.attrs.height}">

        <f:facet name="header">#{cc.attrs.header}</f:facet>

        <f:facet name="controls">

            <h:outputLink

                value="#"

                onclick="onWindowMin(#{rich:component('#{cc.clientId}')}); return false;">

                <h:graphicImage value="/images/window/win_minimize.png" id="toggleIcon"/>

            </h:outputLink>

            <h:outputLink

                value="#"

                onclick="#{rich:component('#{cc.clientId}')}.hide(); return false;">

                <h:graphicImage value="/images/window/win_close.png" id="closeIcon"/>

            </h:outputLink>

        </f:facet>

        <cc:insertChildren/>

    </rich:popupPanel>

</cc:implementation>

</body>

</html>

and then use it in one of the pages

          <h:inputText  id="targetChla" valueChangeListener="#{susLoadPlot.onTargetChlaChange}">

                <a4j:ajax  event="keyup" execute="@this" render="targetSusLoad targetPercentReduction"/>

                <rich:componentControl target="disclaimerDialog" operation="show" />

          </h:inputText>

        <widget:dialog id="disclaimerDialog" header="Disclaimer!">

            <h:outputText escape="false" value="#{msg['module.disclaimer']}" />

        </widget:dialog>

However, when I use the component, the following exception is thrown

SEVERE: javax.faces.FacesException: Component ID discliamerDialog:j_id2 has already been found in the view.

+id: discliamerDialog

         type: javax.faces.component.UINamingContainer@199f755

          +id: j_id2

           type: javax.faces.component.UIPanel@1fdff07

            +id: discliamerDialog

             type: org.richfaces.component.UIPopupPanel@16e9494

              +id: j_id2

               type: javax.faces.component.UIPanel@724356

                +id: j_idt71

But if i don't define id inside the composite component, rich:componentControl does not work as it cannot find the exact match id

Tried to use following instead but still not working

<rich:componentControl target="#{rich:findComponent('disclaimerDialog*')}" operation="show" />

Any solution to this?
