Summary 0004605: JvDBGrid [ and JvDBUltimGrid?] cannot be created in Korean. Access violation occurs
Description Duplicate of 0003026. Seems that the issue had been properly identified but the fix was incomplete: FChangeLinks must indeed be created *before* setting Options.

The following works (only changed the order of the lines)

constructor TJvDBGrid.Create(AOwner: TComponent);
  ...
  FChangeLinks := TObjectList.Create(False); // BEFORE setting Options below
  inherited Options := inherited Options - [dgAlwaysShowEditor];
  ...


while the latest code from Trunk (revision 11987) still causes an AV:

  ...
  inherited Options := inherited Options - [dgAlwaysShowEditor];

  // (obones): issue 3026: need to create FChangeLinks at the beginning
  // so that any change can access the object. It seems that on some
  // foreign systems, the assignment to the Options property triggers
  // NotifyLayoutChange, so it needs the FChangeLinks object
  FChangeLinks := TObjectList.Create(False);
  ...

Suggested fix has been tested on XP with Korean system language. See 0003026 for background information.

PS: Didn't check JvDBUltimGrid, but the original poster mentioned it, so it will also probably be affected.
