This is a misuse on your part, however the documentation could perhaps be clearer.
I think you are using

first_name =>'password',second_name =>'confirm'

When you should be using

first_options =>array('label' =>'password',),second_options =>array('label' =>'confirm',)

In almost all use cases for the repeated field there is no need to use thefirst_name &second_name options

@tommygnr could you please create an issue explaining what should be improved? Then we can close this one.

@alexcoventry bad that this wasn't a real bug! Hope to see other fixes from you in the furture.

@tommygnr No, you're right, the documentation is clear and I was confused. Sorry about that. But actually I was using first_options => 'password'. I mentioned {first,second}_name because those actually work for me.

Hi guys!

I've made a change at sha:4b5a44a to hopefully make this clearer. We actually already had a note, but since it was below the example, I'm not sure if people noticed it :).

Thanks!
