In the RF demo(http://livedemo.exadel.com/richfaces-demo/richfaces/include.jsf), <a4j:include> is used inside a form. That means

<h:form>
 <a4j:include viewId="/richfaces/include/examples/wstep1.xhtml" />
</h:form>

I wonder if it is mandatory to put <a4j:include> in a form. I wrote a small example where I put <h:form> inside the <a4j:include> and it works.

I would like to have some confirmation from RF developers or those who used <a4j:include> before.

Thank you.
