I opened the yui-ext.jsb file in JS builder and selected all modules. The resulting build does not include the class YAHOO.ext.Button while thre is a reference to it in the BasicDialog class :

Code:
var btn = new YAHOO.ext.Button(this.footer, bconfig);
As a result, dialogs are not working in the yui-ext.js build file.

Am I doing something wrong?
