I have a `<p:dataTable>` in a facelet. The facelet is included into a page. A selection of a table row should trigger an update on an element of the surrounding page.

When I include the `<p:ajax event="rowSelect" update=":open:separate" />` inside the table, all works fine. But I am using the table on multiple pages and cannot guarantee a constant Id for the updated element.

I have tried removing the `<p:ajax>` from the table and wrap the included table inside it like this: 

```
<p:ajax event="rowSelect" update=":open:separate">
    <ui:include src="/open/components/submittersTable.xhtml"/>
</p:ajax>

```

I get this error (root cause abridged):

```
javax.servlet.ServletException: /open/index.xhtml @30,59 <p:ajax> Event:rowSelect is not supported.
    javax.faces.webapp.FacesServlet.service(FacesServlet.java:606)
    org.jboss.weld.servlet.ConversationPropagationFilter.doFilter(ConversationPropagationFilter.java:62)

root cause

javax.faces.view.facelets.TagException: /open/index.xhtml @30,59 <p:ajax> Event:rowSelect is not supported.
    org.primefaces.component.behavior.ajax.AjaxBehaviorHandler.applyAttachedObject(AjaxBehaviorHandler.java:148)
    org.primefaces.component.behavior.ajax.AjaxBehaviorHandler.apply(AjaxBehaviorHandler.java:126)

```

Am I having wrong ideas about what is possible with `<p:ajax>`? Do I have to include it into the table and try forcing the ids on the surrounding pages to fit? Or is it possible to wrap `include` with `ajax` and I'm just doing it wrong?

Thank you
