The PATH for the first element ('/'.join(metadata['PATH'])) is 
'/DF/Current/01_folder'

The trouble with manage_addFolder(...) is that it does not complete a 
transaction until the script running it finishes, so the newly added 
folder is not available to me until after the script is done, but I want 
to modify the content of the new folder in the script i am running. 
invokeFactory(...) on the other hand does complete the transaction 
immediately so i can perform the updates i want.

I'll take a look at the debugger :-)

It is a pity that there isn't some example documentation for the proper 
use of invokeFactory, constructInstance, and constructContent in 
external methods.
