XForms/Entity Selection

MotivationEdit

You want a user interface control that allows a user to select a legal entity in a contract such as a person or an organization. The list of people or organizations are supplied in a list that includes an id and a screen label. You want as-you-type functions to narrow down a list of choices from these lists.

MethodEdit

We will create a user interface control with two tabs. The first tab will be for people and the second will be for organizations.

Screen ImageEdit

Entity Selector Control. Note that only the person names that contain the string 'John' are displayed
