Hi Gustavo,
I'm no expert but one way is for the second controller's Content Array or
Content Set to be bound to some property of the first controller's
selection.
For example if you have an entity "Foo" with a to-many relationship called
"bars" you would:
- bind the "content set" of bars array c
Thanks for the help. The main gap in my understanding was that by default an

and converting an object to a string. It is therefore fussy about how the
user types the string.
By subclassing the formatter you can customise
