Hi,All What I want to ask is: If we attemp to book a flight which already be locked by another client. What the current client GUI should look like? Standby or still active for other operations such as search or book another flight. Is it not allow for GUI to freeze while the lock is work on? In my way , my GUI will available for operation while the lock was blocked which means my client get the record control. But I wonder its right.
Well Jeff, that's an interesting question. And it is one without a real answer. It all depends on what experience the users want against what you think is the safest and bug proof way. Meaning if you allow the user to continue while it is waiting for the lock, is there any data corruption that could possibly happen, thread control, etc. While the record is being locked you can have a screen pop up that says "Currently Processing your Request, Please Wait". This is always nice to the users and is "User Friendly", an hourglass can also work, but not as user friendly. It is up to you to decide, and to put your decision in your design.txt and explain your position. To be honest, I did nothing, the user just waits. Mark
