form control renders two times after call validate() function

Hi,
Please have a look at this snippet: http://webix.com/snippet/f2ba10f6
At the first time open this snippet page, click to Save button but the invalid message does not appear after call validate() funtion. If I click again, the invalid message will appear. If you refresh the page, and click Save button, the result is the same.

When I debug in my local machine (Webix pro 3.1.2), I saw that Webix render the form two times at the first click to Save button. If I re-click to Save button, it just renders the invalid fields.

I think this is a bug. Could you help me please?

Hi,
