I was referring to the jQuery UI dialog.
See http://jsfiddle.net/mzoagwjf/2/.
In setting this up, I discovered that there is no problem with jQuery-ui versions <= 1.9.2 as in the fiddle. If you change the jQuery-ui.js to 1.10.4, the problem appears.
So not sure this is really a problem with your components per se, but perhaps you can easily spot where it is going wrong?
Thanks.
