menuItem submitMode="ajax" conversation propagation control

[dcernahoschi]

I'm using richfaces 3.3.3 and seam 2.2.2. I want to specify the conversation propagation policy with the menuItem component. Something like this:

<rich:menuItem submitMode="ajax"...>
    <s:conversationPropagation type="none"/>
</rich:menuItem>

But the s tag doesn't seem to have any effect.

It works fine with submitMode="server". Like this:

<rich:menuItem submitMode="server"...>
    <s:conversationPropagation type="none"/>
</rich:menuItem>

Or submitMode="none". Like this:

<rich:menuItem submitMode="none" ...>
    <s:link ... propagation="join"/>
</rich:menuItem>

Am I missing something in the ajax case?
