We have a datebox in a popup and this popup is opened in a modal window.
When we click on the datebox button, the popup disappears...

I simplified the code here: zk Fiddle
To see the bug, click on level+, next in the new window click on popup, next in the popup click on the datebox button. The pop-up is automatically closed ...
We have not the problem in the first level.

We use version 6.5.1 of ZK and the problem does not depends of the browser.

It is a way to get around this problem before to have a correction ? By css ?

See Example.png to see our application. The listbox is in a modal window.

Thanks for your help
