IWAppFormProcessParams

[Lorbass]

Hello,

when exactly does IWAppFormProcessParams fire?

procedure TFormA.ButtonAsyncClick (Sender: TObject; EventParams: TStringList);
var
  F: TIWAppForm;
begin
  F:=TFormB.Create(WebApplication);
  F.Params.Add('AName'+F.Params.NameValueSeparator+'AValue');
  F.Show;
end;

In Form B neither IWAppFormProcessParams fires, nor are the parameters available in IWAppFormRender:

procedure TFormB.IWAppFormRender(Sender: TObject)
var
  S: string;
begin
   S:=Self.Params.Values['AName']; (* returns an empty string *)
end;

Thanks for quick reply!
