Hi everybody, I am using Rails 2.3 and the new "nested forms" concept to add child objects to a parent object from within a single form. I have successfully gotten the example app from Github (alloy_complex- form-examples) to run and modified the Javascript code (add_child) to insert new child elements betwee existing children, _not_ only at the end of the list of children. This works fine, client-side. However, this order is not preserved. When I try to save the form, the new children are simply appended to the list of children. Now I could solve this by populating a "position" attribute using Javascript. But when validation fails, the list of children is _also_ reordered before Rails re-renders the form, so that new children always appear at the end. How do I define, within a form_for / fields_for construct, the ORDER of child elements so that it will be preserved * upon re-rendering the form (when validations fail or exeptions occur) * upon successfully saving the object ? I have a "default_scope :order => :position" set in the child model, which also works fine, but does not help in the first case. How is the "accepts_nested_attributes_for" implemented, can I somehow hook into this? Thanks!
