Hello,

I'm giving a try to 0.13-SNAPSHOT version and found a weird bug.

When I add a widget to the page. In this case it's a W3C widget. It adds 
A LOT of times to page.

This means that I have 100 times added the widget and the page completly 
blocks.

But I only did click one time.

I noticed that in previous version you can click the button several 
times without noticing that the widget was added. In this version you 
cannot because the button is disabled. But something in the back adds it 
a lot of times.

Any point on this?

Thank you.
