Question

The first input is and I init the datepicker like this jQue

Answer 1

As mentioned, this is a known bug with jQuery UI and should be fixed relatively soon. Until then...

Here's another option, so you don't have to mess with tabindex:

Disable the datepicker temporarily until the dialog box opens:

dialog.find(".datepicker").datepicker("disable");
dialog.dialog({
    "open": function() {$(this).find(".datepicker").datepicker("enable");},
});

Works for me.
