Hi Fernando,

 > This small patch includes a few more test situations for the runtime

 > - Checks if it returns nothing when there is no parent object;
 > - Ensures that attributes mentioned after the parentGUID are returned

 > constructed parentGUID development).

Thanks! I've pushed it to master.

Cheers, Tridge
