Title: Rails3 name-one tag check for this_parent.nil? added

I've had a problem with this like:

You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.errors

so added check before evaluating this_parent.errors
