I have a problem with the ComBo When I what to bound it to a field.

I have 5 cbo in my form, and all 5 cbo are set like this:
.BoundTo = .t.
.controlSource = MyAlias.MyField1 && MyField2 for the second etc.
.RowSourceType = alias
.RowSource = MyTempCursor

When I open the form, the cbo is not position on the right selection, but if I open the cbo, the right selection is preselected in the list.

Is this normal because all 5 cbo point to the same RowSource?
