Undefined method error using simple example

[geremyCohen]

Hi-

In my show partial, I get:

undefined method `empty?' for #<MyModel:0x00000003003a18>

Stack trace:

activemodel (3.2.13) lib/active_model/attribute_methods.rb:407:in `method_missing'
activerecord (3.2.13) lib/active_record/attribute_methods.rb:149:in `method_missing'
tabletastic (0.2.3) lib/tabletastic/helper.rb:18:in `default_class_for'
tabletastic (0.2.3) lib/tabletastic/helper.rb:6:in `table_for'

Using your simple example:

<%= table_for(@bundle) do |t|
t.data
end %>

Ruby 1.9.3 on Rails 3.2.13

Any ideas?

Thanks!
