[JS] app.menuActions on XMLElement

Hi,

I'm trying to apply italics using xml rules and this method : http://forums.adobe.com/thread/744713

function Italique() {      this.name = "Italique";      this.xpath = "//hi[@rend='italic']";      this.apply = function(myElement, myRuleProcessor){           with(myElement){                app.select(myElement);                app.menuActions.itemByID(119611).invoke();           }           return true;      } }

myElement is an XMLElement who contains exactly what I want but at :

app.menuActions.itemByID(119611).invoke();

a javascript error occurs : n° 54 at line 78 of the "glue code.jsx" file.

"Exception Javascript non interceptée : Erreur : Le script n'est pas activé"

In English : the script isn't activated.

I don't know what to do.

Help me please!
