[Pas2js] TJSIDBObjectStore.add() not working with a recordtype variable.....

[Pedro Pablo Oviedo Vera]

Yes, you all right!...I am try it ....my problem :
...for example...I declare >>>>>
type
  gsolicitud    : TJSIDBOpenDBRequest;
   gMyDB       : TIDBDatabase;

function fOpenDB(aEvent: TEventlistenerEvent): Boolean;
begin
(* inside event handler I need get params retorned from request   *)
gMyDB  := aEvent.target; <==== but this does not works for me
gMyDB  := gsolicitud.resultAsDatabase; <==== so I must try this !!! :-( but
it is not correct!
end;

begin
  ......
  gsolicitud  := Window.indexedDB.open(gDBName,4);   <<<< I requesting for
this event
  gsolicitud.onsuccess := @fOpenDB;                            <<< and set
this function to handles this event
  ......
end;

When I go to the event handler function I try get params returned through
aEvent.target (  gMyDB  := aEvent.target;  ) but compiler tells type
missmacthed!, then I just try solve it do some thing like this ( gMyDB  :=
gsolicitud.resultAsDatabase; )....it is not just in this case ...it happend
to me always that I need recover a param inside of an event handler
function...so if some one has an answer about it please illustrate
me..THANKS
