How to extend existing validators?

[andriijas]

Hi

Im trying to extend existing validator but I get typeerror because of wrong scope

Is there any way I can do this so that it works?
How would I extend the default set of validators to add this so that I can use it in other places in my app?

Thanks

  multipleEmails: (value, attr, computedState) ->
    emails =  if value then value.split(',') else []
    for email in emails
      foo = Backbone.Validation.validators.pattern email, attr, 'email', @
      return "#{attr} must contain a comma separated list of emails" unless foo
    ''

This is a bug. You can get around it by not calling the built-in validator(s) from a custom, and just copy the code.
