Json de-serialization order

Hello,

I have a problem de-serializing a json string. After I get false from de-serialization function, I see some variables have value in my record.

In order to find my mistake, I would like to understand how mORMot doing de-serializing order.

For example I have below json string:

{"name":"test","surname":"test"}

And my record definition is:

type
  TPerson = packed record
    surname: string;
    name: string;
  end;

When de-serializing, is it name or surname that is filled in record variable first?

Thanks & regards,
Ertan

Re: Json de-serialization order

{"name":"testname","surname":"testsurname"}

Will set 'testname' into TPerson.name and 'testsurname' into TPerson.surname.
There is no such thing as "fill order"... it just put the right values in the right fields.
Note: if the record and the JSON have the same order, then it may be slightly faster to work with (no need to lookup the field name).
