Scope of params form componentControl

[slcon1]

The Exadel livedemo documentation says:

You may put f:param components as nested to component control component and all the parameters that are defined will be available from target component.

I want to transmit parameters to an modal panel but don't get it work. It only seems to work with context menus.

<rich:contextMenu id="SHOW_MENU">
 <rich:menuItem >
 <h:outputText value="{myParam}"/>
 </rich:menuItem>
</rich:contextMenu>

<rich:modalPanel id="SHOW_PANEL">
 <h:outputText value="{myParam}"/>
</rich:modalPanel>

<h:outputText id="componentTest" value="Component Test" >
 <rich:componentControl for="SHOW_MENU,SHOW_PANEL" event="onclick" operation="show">
 <f:param name="myParam" value="somevalue"/>
 </rich:componentControl>
</h:outputText>

Does anyone know what I'm doing wrong?

Thanks in advance,

The modal panel can show the value in an alert box but doesn't show it in the outputText.

<rich:modalPanel id="SHOW_PANEL"
 onshow="alert(event.parameters.myParam)" > <%-- Alerts "somevalue" --%>
 <h:outputText value="{myParam}"/> <%-- Shows "{myParam}" --%>
</rich:modalPanel>

<rich:contextMenu id="SHOW_MENU">
 <rich:menuItem >
 <h:outputText value="{myParam}"/> <%-- Shows "somevalue" --%>
 </rich:menuItem>
</rich:contextMenu>

<h:outputText id="componentTest" value="Component Test" >
 <rich:componentControl for="SHOW_MENU,SHOW_PANEL" event="onclick" operation="show">
 <f:param name="myParam" value="somevalue"/>
 </rich:componentControl>
</h:outputText>

How Can I pass values to the modalPanel?
