hi all
I'm playing with calendar demo
(.../lazarus/components/googleapis/demo/calendar/calendardemo.lpr)
using fpc 2.6.5 and lazarus 1.5

I followed README.txt instructions: I can run this demo and I can see
calendards and events.

In the events listbox I've added a double click event to try to update
an event with following code:

Code: [Select]procedure TMainForm.LBEventsDblClick(Sender: TObject);
var Entry: TEvent;
begin
  Entry:=Events.items[LBEvents.ItemIndex];
  Entry.description:=Entry.description+'[modified]';
  try
     FCalendarAPI.EventsResource.Update(FCurrentCalendar.ID, entry.id,
Entry);
     ShowMessage('response: ok');
  except
    on e: exception do begin
       ShowMessage('response failed:'+#10+e.Message);
    end;
  end;

end;
 
I always get this negative response:
Quote400 error executing request :  Bad Request
Using debugger I can see request appear correct to me.
Where I'm wrong?

Thanks in advantage

you can set the webclient.logfile to some valid filename and examine
the resulting file after the request. It should contain the complete
response of google

Note that you better use the Patch method if you're just changing some
properties.
