Problem: An Editable table causes an error leading to reserved seats can booked again. Steps to reproduce: 1. Login 2. Select Concert 3. Select Concert Ticket 4. Change the value in the table 5. Choose the seat that just modified. Expected Result: A seat with a star (*) should not be reserved as it is taken.
The bug fixed. The seat field of the table is now unchangeable by adding a statement (table.setEnabled(false);) in concert page.
