Error 3270 property not found
A2007. I get the 3270 error when saying Cancel in BeforeUpdate of a combo (whether or not I Undo the combo). I have no clue where it comes from, the debugger does not help: I step through my BeforeUpdate, and the next thing after exiting the sub is whammo.. error 3270.
Initially the thing just said property not found, but I got the error out of the form's OnError handler.
The combo is a bound control in rows displayed in datasheet view of a subform.
It's a bit tricky to extract a skeleton version to illustrate the error, so before doing that I was hoping someone might provide some hints as to how to track down this error. I could set the handler to ignore it , since apparently nothing bad happens, but it's just a bit annoying and inexplicable.
