Hi the difference between "destination" and "destino" vars was a
typing error :D When I was posting this issue I tried to "translate" a
bit the code :D But in my code both vars are named "destino", so this
was not the issue. Consider both to be "destino", ok?
So, I'll try to explain the problem again, ok?
The first time an user types something into his text box, the code
will save that value in this form:
///////////// var arrayofvalues[timestamp_of_now] =
typed_code_input_box;
///////////// var json = gadgets.json.stringify(salvarDestino);
so, in a json structure, we would have something like this, right?:
///////////// {
///////////// timestamp_of_now : typed_code_input_box,
///////////// }
when I save it like this:
/////////////
req.add(req.newUpdatePersonAppDataRequest(opensocial.DataRequest.PersonId.VIEWER,
'ownerDestino', json));
i would have something like this, in the server-json structure:
///////////// {
///////////// XXXXXXUSERIDXXXXXXX : { ownerDestino :
{ timestamp_of_now : typed_code_input_box, } },
///////////// }
right?
so, when the user types something else, to change the value, I want
the data strucuture to be like this:
///////////// {
///////////// XXXXXXUSERIDXXXXXXX : { ownerDestino :
{ new_timestamp_of_now : new_typed_code_input_box, } },
///////////// }
So, the older value should be erased. Hhowever, i'm getting something
like this:
{
XXXXXXUSERIDXXXXXXX : { ownerDestino : {
timestamp_of_now : typed_code_input_box,
new_timestamp_of_now : new_typed_code_input_box,
} },
}
or maybe this:
{
XXXXXXUSERIDXXXXXXX : { ownerDestino : { timestamp_of_now :
typed_code_input_box, } },
XXXXXXUSERIDXXXXXXX : { ownerDestino : { new_timestamp_of_now :
new_typed_code_input_box, } },
}
So, I want the older value to be cleared, and only the new one to be
saved. I Thought my script would do this, because, tecnically, it
would overrite the entire 'ownerDestino' key! However, I'm always
getting more than 1 result when I fetch the values.
So, this is it, can you help me ?
thanks,
Samuel Brandão
