Hi Aleksey.
I am not using ON ERROR statement.
I am just using the CursorAdapter.BreakOnError = .F., so if some error occurs it calls the CursorAdapter.Error event. Then in Error event I tried to RETURN .F., but VFP just go ahead with update process.
I don´t know if you tried to do somenthing like that? It looks like a bug in VFP... I don´t know...

Does somebody has some idea to work arround this?

Thanks anyway.
Ricardo.
