Help! how to add pop up menu in the table head?

[kanxg]

The richfaces could add a context menu on the datatable, you can see the second demo in:
http://livedemo.exadel.com/richfaces-demo/richfaces/contextMenu.jsf?c=contextMenu&tab=usage

right click every element in table, the pop up menu will be shown.

But in my case, I need to right click the table head to show the pop up menu. How to do it?
I just attach the rich:contextmenu into the <f:facet name="header">, but it throw error.

So how to do it?
below is the code:

==================================
<rich:contextMenu attached="false" id="menu" submitMode="ajax">
<rich:menuItem ajaxSingle="true">
<h:outputText value="#{messages.a}"/>
</rich:menuItem>
</rich:contextMenu>

<f:facet name="header">
<rich:columnGroup>
<rich:componentControl event="onRowClick" for="menu" operation="show">
<f:param value="#{propertyTooltip}" name="propertyTooltip"/>
</rich:componentControl>
<rich:column rowspan="2">

<f:facet name="header">
<a4j:outputPanel layout="block">
<rich:contextMenu id="menu" event="oncontextmenu" submitMode="ajax">
<rich:menuItem ajaxSingle="true">
<h:outputText value="#{messages.a}"/>
</rich:menuItem>
</rich:contextMenu>
<a4j:outputPanel/>
</f:facet>

Hi, ilya_shaikovsky .
it throw below error:
Error Parsing /test.xhtml: Error Traced[line: 14] The prefix "a4j" for element "a4j:outputPanel" is not bound.

my code is same with yours:
<f:facet name="header">
<a4j:outputPanel layout="block">
<rich:contextMenu id="menu" event="oncontextmenu" submitMode="ajax"> <rich:menuItem ajaxSingle="true">
<h:outputText value="test"/>
</rich:menuItem>
</rich:contextMenu>
<a4j:outputPanel/>

could you help me?

o . the reason is my lib conf is:
xmlns:a="http://richfaces.org/a4j"

. but even i change it to a4j=. the code doesn't work. no error. no pop up menu.

[ilya_shaikovsky]

not sure that understand the latest problem please show new actual code and the result.

[kanxg]

the result is the table could be shown,but right click on table head, no pop up menu.

code is:

<rich:dataTable id="table"
var="_testvar"
value="#{testvares}"
rows="#{testvar.pageSize}"
rowClasses="lightRow,darkRow">
<f:facet name="header">
<a4j:outputPanel layout="block">
<rich:contextMenu id="menu" event="oncontextmenu" submitMode="ajax">
<rich:menuItem ajaxSingle="true">
<h:outputText value="#{messages.a}"/>
</rich:menuItem>
</rich:contextMenu>
<a4j:outputPanel/>
<rich:columnGroup>
<rich:column rowspan="2">
<h:outputText value="#{messages.test1}"/>
</rich:column>
<rich:column rowspan="2">
<h:outputText value="#{messages.test2}"/>
</rich:column>
<rich:column rowspan="2">
<h:outputText value="#{messages.test3}"/>
</rich:column>

so context menu defined only in header.. and it will be shown only in header.

[kanxg]

Yes,It should only shown in header, but when I click the head column, nothing happen.
