I want to create a custom field similar to the assignee field but I'd prefer not to use the User Picker field type because it doesn't work well with the GreenHopper plug-in. If you are editing a User Picker field via the GreenHopper Card View, you have to remember the user name in order to have the field update correctly. The Asignee field is much more user friendly because you can just start typing the name of the person and it displays a list of potential people with their associated e-mail address.
Can I replicate this behavior somehow?
Thanks in advance,
Troy
