which method should be called when user will click on release button from gui?
I am updating customerid field when user enters userid and click on book button and when user click on release than I am
making that userid empty .
is it okay ?
But Sun Spec says that
"The id value (an 8 digit number) of the customer who has booked this. Note that for this application, you should assume that customers and CSRs know their customer ids. The system you are writing does not interact with these numbers, rather it simply records them. If this field is all blanks, the record is available for sale."
what to do on click on book or release button from gui?
