Hi all! Playing around with in_place_editor_field, I found that when you set a field to be empty, you can''t edit it at all anymore after that. Am I doing something wrong or is this the way it is intended to be? If so, is there any way around that behaviour? Is it just styling? Best regards, Raphael -- Posted via http://www.ruby-forum.com/.

Hi all I''m moving to using Machinist in my rspec tests and am having a problem with an after_create callback method that i need to stub out.
