Here's an easy—and I suspect faster—way to parse the long id for  
traversal up the hierarchy of objects:

get the long id of the selectedobject; replace " of " with "," in it;  
put it

which results in:

    field id 226375,group id 226358,group id 226332,card id  
224190,stack "..."

then a simple "for each item" loop to traverse it.

The engine doesn't have to fetch the ID but once.
