Summary0003215: TJvDBCustomSearchComboBox Bookmarks memory leak
Description      while not EOF do
      begin
        Items.AddObject(FieldByName(FDataLink.FDataFieldName).DisplayText, GetBookmark);
        if Bookmark = Bmrk then
          CurIndex := N;
        Inc(N);
        Next;
      end;

I think that in function ReadList we've got memory leak during call GetBookmark function (see above). In the example below there is a memory leak (see comments)

type
 TExampleFrame = class(TFrame)
   ComboBox: TJvDBSearchComboBox;
 end;

implementation
{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
var
 DataModule: TDataM;
 Frame: TExampleFrame;
begin
 DataModule:= TDataM.Create(Application);
 Frame:= TExampleFrame.Create(PageList.Pages[0]{example owner});

 Frame.ComboBox.DataSource:= DataModule.TypesSource;
 Frame.ComboBox.DataField:= 'Type';

 Frame.Parent:= PageList.Pages[0];
 Frame.Free; //In that configuration there is
 DataModule.Free; //a memory leak
// DataModule.Free; and in that configuration
// Frame.Free; there isn't memory leak
end;
TagsNo tags attached.

A call to clearlist has been added in the destructor, this should solve this problem. It will be added to CVS as soon as the system is back online.
