/**  
 * La funzione windowOpen consente l'apertura di una finestra popup su cui redirigire una action faces. E' testata su explorer e firefox.
 * Per utilizzarla basta creare un commandLink in pagina nascosto come il seguente:
 *
 * <h:commandLink  style="display:none;" id="linkNascosto"  target="Popup" value="aaaaaaaa" action="#{mioBean.miaAction}"/>			
 *
 * Dove target č il nome assegnato alla popup ed action č la action di destinazione quindi anche expression language
 * Un button visibile in pagina permetterā di aprire la popup con il seguente codice:
 *
 * <h:commandButton value="LINK POPUP" onclick="windowOpen('myForm3:linkNascosto','Popup',500,500,false);return false;"/>
