Dialog: "unspecified error" when using ie9 and iframe

Hi,

Sorry for reporting this again, but I couldn't find a way to reopen ticket #8443.

I've updated my install to jqueryui version 1.10.4.

However, I'm having the same problem (en ie9, inside an iframe) in the dialog "dialog.open" method

As far as I see, the correction was only for the "dialog.close" method.

Problem still happens in line 232.

Sorry, but I can't post a "minimum example" right now.

I solved it like this:

try {

this.opener = $(this.document[0].activeElement);

} catch( e ) {

this.opener = $(document.body);

}
