There is still the option of using the standard "outputLink" control and then
hook in to the prerender() callback of the view controller. This performs a GET
request so all state must be loaded as query parameters on the anchored link.
<h:ouputLink value="http://myotherapp"/>
<f:param name="key" value="#{mbean.someKey}"/>
</h:outputLink>
public prerender() {
Map params = (Map) getBean("param");
String someKey = (String) param.get("param");
}
