In controller the line 140 is

@account.update_attributes(permitted_params)

with

def permitted_params
    params[:account].permit(:lock_version, :username, :password, :company_id, :usersgroup_id, :isadmin,
                            :locked, :newpassword, :password_confirmation, :last_service_id, :last_successful_login,
                            :total_logins , :password_changed , :password_change_given, :oldpassword , :last_active_at)    
  end

What version of JRuby? Similar bugs have been fixed in releases the past few months.

Latest version, 1.7.9, I switched to jruby just a few days ago...

Ok, thanks.

There's several possible reasons for this that are hard to sort out without a reproducible example. Can you come up with a script or a demo repository that we can use to reproduce?

I will try to isolate it.

The curious thing is that the same syntax works in other models, eg:

def startdate_string
    self.startdate if self.startdate
end

  def startdate_string=(new_val)
    if new_val && new_val!=""
      just_for_check = DateTime.strptime(new_val, fmt=Time::DATE_FORMATS[:app_date])
      self.startdate = new_val
    else
      self.startdate = ""
    end
    rescue ArgumentError
      @startdate_invalid = true
  end

@PanDar1 it appears you're working with Rails here, I'm not sure how to reproduce this in order to see if it has been fixed in newer versions of JRuby.

Would you please provide a reproduction case or at least validate whether the issue is still present for you on newer versions of JRuby?

no response - probably no longer valid. please let us know if issue persist on latest of JRuby 1.7
