Hello, I use Ext JS and Catalyst. All works fine but now, I am to add some TT instructions into my javascript files : Example : Ext.define('MyApp.MyWindow', { extend: 'Ext.window.Window', [% IF user %] ... my code ... [% END %] title: 'MyWindow', }; My Ext JS file is in root directory. How can I do that ? Thanks, Jean-Marc
