What is the problem you are trying to solve?
Liferay Objects offer the Assignee field type, but there is no form fragment for it: the mapping table in the Using Form Fragments documentation does not list the type, and the Form Container falls back to a generic Text Input. There is no way to select a user; the assignee has to be typed as plain text. This
makes the field type unusable on page-based object forms, while the auto-generated Object Entry edit form in the admin UI renders a proper user picker for the same field.
An object field type is only complete when it can be used in forms. Every field type the product offers should come with a corresponding form fragment.
Liferay Support has confirmed the gap (support ticket LRHC-154747; the internal ticket LPD-75623 apparently covered the same request but was closed without a visible resolution). Related discussion: Form Fragment for Assignee Field – User Picker instead of Text Input?
What is your project about? (e. g. Intranet, Partner Portal, Enterprise Website, etc)
A B2B customer portal (self-service and commerce) built on Liferay DXP Cloud. We model business data with Liferay Objects and build the user-facing forms with the Form Container fragment; several of these forms assign an entry to a responsible user.
What is your proposed solution? (optional)
A form fragment for the Assignee field type, usable within the Form Container, that renders the same user picker as the auto-generated Object Entry edit form.
