I have a user bean with a Set of Role Beans.
In my form to add/edit a user bean, I display a drop down list populated with existing Roles.
I have a button that when clicked, adds a Role repeater with hidden fields for id and name, and output widgets to display them to the user.
The problem is some odd behavior - If I load the form, add a role, then remove it, then add it again, it saves properly.
If I load the form, add a role, and hit save, it saves a new Role with NULL values.
I am starting to think I simply am missing something fundamental about the binding framework.
I am using cocoon 2.1.6
