nil issue after creating plate

[branch14]

after rake db:migrate and rake db:seed everything seems fine until i create my first plate, then I get this

ActionView::TemplateError (You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.<=>) on line #5 of app/views/plates/_plate_filter.html.erb:

Thanks for reporting, I can take a look at this tomorrow.

Fixed. There was an issue with the seed file setting the instance_name to nil. This wouldn't happen from the form.

I thought validates_format_of wouldn't allow nil but, as it turns out, if you allow "", you'll also allow nil, since nil.to_s == "".

branch14, just dump your db file and start again. Or set the instance_name for the seeded plate to "".

Thx kasima, great response time. Thx also for your work on being more 'platform agnostic'. That's basically what I did to set it up on my machine.
