In IBC_ComboBox.IMP , line 421,
Sometimes the aVal parameter pass items value or itemvalues, cause
the display text in grid empty, so i correct the source code for
proper display text .

function TIB_CustomComboBox.IBG_TranslateText(AVal: string): string;
begin
// Result := Items.Strings[ ItemValues.IndexOf( AVal ) ];
Result := aVal;
if Items.IndexOf( aVal ) = -1 then
Result := Items.Strings[ ItemValues.IndexOf( AVal ) ];
end;

Is this correct?
