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!

Hi, try this: (not tested, ok).

 

Code:

 

procedure TFormA.ButtonAsyncClick (Sender: TObject; EventParams: TStringList);

 

begin

 

  with TFormB.Create(WebApplication) do begin

 

    Params.Add('AName' + Params.NameValueSeparator + 'AValue');

 

    Show;

 

end;
