CustomGateFormFieldInterceptorSample

Code Extension Type: GATE_UI_FIELD_INTERCEPTOR (on page 1)

Purpose: This code extension is used to intercept the population of values for an appointment in the Pre-Selection area on the <Gate Stage> tab.

Code example

The following code example implements a code extension of type GATE_UI_FIELD_INTERCEPTOR that updates the Notes field. When you enter the appointment number in the Appointment Number field in the Pre-Selection area and tab out, N4 invokes this code extension and updates the Notes field based on the set value.
