I had created a timetable in the datagrid. The datagrid is able to display individual staff's tiimetable. However, I was prompt an error when I click on this particular staff to view the class schedule.I realised the error is cause by the array collection only retrieve a row from the database; This is because when I added a new row in the selected staff, the error seems to be gone.
Thus, what should I do to remove the error? The Error http://i192.photobucket.com/albums/z63/nellehs/error.jpg Particular Row http://i192.photobucket.com/albums/z63/nellehs/databasecopy.jpg
