Just asking :)

In hindsight, what I ment, was instead of doing the whole traversal thing in 
the EM, I could just hand the EM the field, and a dict with the changes to be 
made, and it would only do the little magic:
vals = field.values
field.values = vals

Had that allready. 
Ended up more or less just pasting that into the EM, then calling the EM from 
a script and just passing it the context.
It just worked, plain and simple. :)

I know, I know but that extra step actually adds 1/3 to the usual cycle of 
editt->reload. And then it ads another layer of indirection when you come 
back later and have to figure out how it works.

It's fld.objectItems(['Formulator Form'])

Sorry to put you to the trouble, I should have been more clear I had that 

Thank you for your help :)
