I have a combo box with the following settings:

.ControlSource = thisform.oAddrInfo.stprov
.Sorted = .T.
.Name = cboStProv
.Style = 0
.RowSource = "nwizprov.stprov"          && Table with alias of nwizprov
.RowSourceType = 6
.Format = '!'
.BoundColumn = 1
.ColumnCount = 1

This allows the user to add provinces into the table if they don't exist in our list. This part works great.

However, if I add the following clause to the When method:

return empty(this.parent.cboAddrId.Value)

I start getting this weird result. If the user enters something into cboStProv that does not exist in the list and then leaves the cboStProv control, when the user re-enters that control, the text they've entered gets wiped out.

If I remove the when clause, the text they entered remains there.

Any ideas as to what is going on and how to fix this? I need the when clause but I need the text to stay there as well.

P.S. I do not add the text they entered to the list until they're done with that form.
