Gostaria de tira uma duvida. Peguei este exemplo do proprio site do PrimeFaces mas mostrou o seguinte:
codigo:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.prime.com.tr/ui">
<h:head>
</h:head>
<h:body>
<p:button outcome="productDetail" value="Bookmark" image="bookmark">
<f:param name="productId" value="10" />
</p:button>
<p:button outcome="productDetail" value="With Icon" image="bookmark">
<f:param name="productId" value="20" />
</p:button>
<p:button outcome="productDetail" image="bookmark">
<f:param name="productId" value="30" />
</p:button>
<p:button outcome="productDetail" value="Bookmark" image="bookmark" disabled="true" title="iconOnly">
<f:param name="productId" value="40" />
</p:button>
</h:body>
</html>
