5.7. Creating Shuttle Layouts
5.7.1. Creating Parent Shuttles
You can use JHeadstart to generate Shuttles. A shuttle is used to present a list of records
to the user. The user can move records from the selected list to unselected and vice versa.
Examples of the use of a shuttle:
1. Defining employees as members of a department. The left part of the shuttle
shows all employees in other departments. The right hand shows the employees
that are selected as members of this department. See screenshot below.
(JHeadstart calls this a parent-shuttle).
2. Attaching roles to a user. The left hand of the shuttle shows all the roles not
attached to the user currently. The right hand shows all the roles the user has
already. (JHeadstart calls this an intersection-shuttle)
Use a parent shuttle when you want to attach existing detail records to parents. For
example, you want to attach employees to departments, or customers to sales
representatives. A parent-shuttle does not create new records, but only updates links to
parent records.
With a parent shuttle you can maintain the relation between employees and
departments.
In this example we will create a parent shuttle to assign employees to departments.
Steps to create a parent shuttle:
1. Go to the Application Module and add another (top-level) usage of the
EmployeesView. Call the usage “EmployeesShuttle”.
