Collection inside of nested property throws an error

[penge]

Hi folks!

By the time of writing this issue, it is already classified as a bug and is getting fixed.
I just wanna to let you know about it.

The model situation is described below.
Let's have a form class like this:

class DocumentForm < Reform::Form
...
  property :a do
    collection :b do
    ...
    end
  end
...
end

Then, when creating the form object with provided models' object...

DocumentForm.new(@document)

...is everything ok, but only if the provided models' object has defined both the :a and :b.

But (this is the issue), if :a is nil and thus the :b is nil too, the reform is trying to assign the :b anyway, but can't because the outer :a is nil.

Have a nice day! :-)
