After giving valid Login ID and Password I entered into an Application. There I selected a tab and Went to the next page.There I selected some by clicking on the Drop down Box and click on "Search Button". After clicking on the Search button the results displayed like a course containing two students. I then clicked on the below two students and click on the "Recover Selected" button. As per the scenario those two check boxes are supposed to be checked automatically(in a disable state), but only one check box is getting checked.
