For a form element of type "Text Input" the ui-disabled class isn't set during initialization of the widget if the "disabled" attribute is already set in the markup.
See http://jquerymobile.com/test/docs/forms/docs-forms.html (Disabling form elements)
This is inconsistent with the behavior of the textinput API, because
$( "#foo" ).textinput( "disable" );
will disable the text field AND set the ui-disabled class.
Thanks for reporting the issues with the disabled textinput. In my comment at #4637 I explained the cause.
Thanks for providing a fix that fast!
Textinput: added conditional call to disable() to the create function…
… to make sure disabled elements get class ui-disabled. Fixes #4636 and #4637 - Text Input doesn't use ui-disabled class if disabled attribute is set in markup. [1.1.2.]
