h:outputLink with multiple f:param

[Mirco Attocchi]

With this code

<h:outputLink
value="#{facesContext.externalContext.requestContextPath}/Print"
target="_blank" title="Print">
<h:graphicImage url="/images/22x22/printer.png" title="Print" alt="Print"/>
<f:param name="type" value="type1"/>
<f:param name="id" value="#{row.id}"/>
</h:outputLink>

I've this uncorrect html output:

<a href="/WebApp/Print?*type=type1&amp;amp;id=34*" target="_blank"
title="Print"><img src="/WebApp/images/22x22/printer.png" alt="Print"
title="Print"></a>

Why?

I'm using MyFaces 1.2.2

Thanks in advance.
