Multi nested expected,

[michaelmoulsdale]

I have implemented the multi-nested version, and all seems to be mainly OK, but I get the following error when I create

(I've changed the model name back to your version for the purpose of clarity)
Resource(#90458220) expected, got Array(#8205400)

I'm use the same accepts_nested_attributes_for approach as I would for a normal single nested, so am struggling to see where the issue is. Interestingly I do get an error if I try to use f.association, saying the association doesn't exit

any thoughts?
