Fix for Issue #262: 'is not focusable' error

[ghost]

link_to_delete now hides the form element and also removes the 'required' attribute on any children of the field being deleted.

field.find('*').removeAttr('required');

Whilst waiting this JS work-around gets you going again:

$(document).on('nested:fieldRemoved', function(event){
  event.field.find('*').removeAttr('required');
});

I think it's better to use $('[required]', event.field).removeAttr('required');.

Could you please update Prototype version too?

Just add this to your assets/javascripts/application.js at it will fix this:

jQuery(function ($) {
  $(document).on('nested:fieldRemoved', function (event) {
    $('[required]', event.field).removeAttr('required');
  });
});
