mobile scheduler add event

I tried the recurring event sample(\samples\02_recurring\01_recurring.html) and I found that when adding the event, first click the “repeat” field, and then do nothing but click cancel to return to the form page. Next, click save. It gets error and shows TypeError: b is null (TypeError: date is null for _debug.js) in firebug.

Any advice so that it can be avoided?

I have attached the fixed libs. Please try them (193 KB)

It works. Thanks!
