Forms 10.1.2 Event engine cycle flow diagram.

Dear Experts,

I have a desperate need to find a diagram that explains the way that Oracle Forms steps through the various triggers and events, which one starts when a form is opened and then the next and the next etc..

 I'm sure that there must be something out there as this is vital to understand where we need to put our code.

I'm also looking for the reason why, when I exit a form I get the following error: FRM-40350 Query caused no records to be retrieved. How can I prevent this error or possible catch it and suppress it?


Thanks again for your help.
