How do I tell Hobo controller about an empty association?

[Bryan Larsen]

Hello,

I'm trying to update has-many to support zero-length associations.

When the association is empty, the view doesn't send any information
about the association to the controller. Hobo's magic controller then
thinks "he's not updating the association" rather than "he's updating
the association to be an empty list."

So I need some way of sending an empty list from the view to Rails'
param hash.

So far, I haven't found a way of doing that. Instead, I pass back an
empty string, and have patched Hobo like below. (I'm not submitting
the patch below, I'm just using it for illustration)

Anybody have any better ideas?

thanks,
Bryan
