Subject Calculated field BUG
Hi ,

opening an IB_Query the first time, in the first CalculatedField event all
other columns contain NULL. The row does not show the correct content. A
workaround is calling RefreshAll() after Open() or closing and reopening the
query. It'd be a pity to have to do that. The fragments of an example below
are just for getting the idea.
IBO 4.2Gc

AutoFetchAll = true/false // no difference either
AutoFetchFirst = true/false // no difference either

__fastcall TForm1::TForm1(TComponent* Owner)

: TForm(Owner)

IB_Query1->RefreshAll(); <--- Then all work's fine
void __fastcall TForm1::IB_Query1CalculateField(TIB_Statement *Sender,
TIB_Row *ARow, TIB_Column *AField)
if ( AField->FieldName == "BES1" )
AField->Value = ARow->GetColumnValue("\"Bes_Name1\"");
else if ( AField->FieldName == "BES2" )
AField->Value = ARow->GetColumnValue("\"Bes_Name2\"");
