Lock_record, then how do I unlock it?

Question

Group,
I have a form that has a multi row view. To be able to edit a given row, the user wants to have the edit in a dialog window. So to ensure data concurency, I want to lock the record before going to the edit window. But the user has an option of canceling the edit. So I need to be able to unlock the record. How do I unlock that given record?
So far my only solution seems to be issuing a forms_ddl('rollback'); followed by a requery of the block. Not very elegant. The rollback gets rid of the lock in the DB, but for some reason the forms record manager still thinks there is a lock because it won't issue another select for update untill the block has been requeried.
thanks.

Answer 1

How about this:
Do not use the Forms editor. Instead, when user "edits" the field, display the contents in an item in a control block placed on a stacked canvas, with all the display settings such that it "looks like" an editor window.
Now, if the user updates the data and exits the editor, you can just replace the text in the source item with the text in the control-block edited item, and standard row-locking will occur.
And if the user cancels, you have not locked the original row.
Of course, if the user has made lots of changes to the data in the item, he will lose all the changes if the row is locked or has already been changed by another user -- he won't get those messages up front like he would with standard Forms input processing.
