Hello there

I developed a zimlet tab app and I launch it using javascript when I do click in a toolbar button. That works fine, my app is open in a tab perfectly using this:

var simpleAppName = this.createApp("MyApp", "zimbraIcon", " MyApp ");
var app = appCtxt.getApp(simpleAppName);	
Inside my zimlet I have a Cancel button and I want to close my tab application (like we close the compose tab) and switch to the Mail View when I do a click on it. So far, I just manage to change the view using this:

But I steel need to close the tab which remains open but inactive, any suggestions please??????
