Validation
.
When you run the Manage Multiple Tickets page, you can test the new validation
either by adding a new ticket with a status of CLOSED and no Closed On date set, or
by removing the Closed On date of an existing closed ticket and attempting to save the
changes. In
Figure 8-20
, each row that doesn't meet the validation requirement is high-
lighted and appears in a list of errors at the top of the page. In this example, the row
that didn't have a Closed On date failed the validation and is flagged as needing atten-
tion.
