Hi, If the dialog is instantiated in a lazy loading panel, maybe the issue could be something like: http://blog.nemikor.com/2009/04/08/basic-usage-of-the-jquery-ui-dialog/
But this kind of behavior is normally fixed in wickte-jquery-ui. But my guess is that it's somehow related to the event binding... Please have a look at the generated javascript in your page and try to isolate the defect... Thanks, Sebastien
