Hi, David,

there are a few things to note.

First of all, the "INS" in the status line refers to Insert mode as
opposed to Overwrite (typical behaviour of the "Ins" key on the
keyboard). The record status is indicated by the *other* 3-letter code
in the status line, like "OK" or "MOD" (for "Modified").

Second, I could not reproduce the behaviour with OnChange but only with
OnValidate. Could you please double-check?

Third, the behaviour is *somewhat* correct for OnValidate: Since
OnValidate only runs on commit, the data is already written to Appserver
and the object *does* exist, but the transaction is not yet committed.
The object is very much in a status like a record in a SQL database is
between the INSERT and the COMMIT statements.

We might have to think a lot more about exception handling and handling
of started but unfinished transactions, but at least I wouldn't consider
this a clear but which can be fixed without some deeper thought about
the basic concepts.

Thanks,
Reinhard
