Get a Field Value Action with Task or Appointment

After performing the initial steps, get values from the Task and Appointment objects with getRecordByContext and getFieldValue global functions.

const getFieldValue = await $modules.uiEventsFramework.getFieldValue('ObjectName.FieldName',  callGetRecordByContext.response);

The following action chain listens for the OnChildRecordOpen event and retrieves the Subject value from an Appointment child record.

When a Task or Appointment create or edit page opens, the event provides the child record’s objectId and objectType. The action chain uses these values with getRecordByContext to obtain the child record’s UEF context. It then uses that context to retrieve the Appointment.Subject field value.

define([
  'vb/action/actionChain',
  'vb/action/actions',
  'vb/action/actionUtils',
], (
  ActionChain,
  Actions,
  ActionUtils
) => {
  'use strict';

  class recordLevelEventListener extends ActionChain {

    /**
     * @param {Object} context
     * @param {Object} params
     * @param {{data:any,eventName:string,recordType:string}} params.event
     */
    async run(context, { event }) {
      const { $page, $flow, $application, $base, $extension, $constants, $variables, $modules } = context;

      switch (event.eventName) {
        
          case 'OnChildRecordOpen': 
          
             const callGetRecordByContext = await $modules.uiEventsFramework.getRecordByContext($variables.uefContext,
               { objectId: event.data.objectId, objectType: event.data.objectType });
            
               const callGetFieldValue = await $modules.uiEventsFramework.getFieldValue('Appointment.Subject', callGetRecordByContext.response);
          
          break;
        
        
      }

    }
  }

  return recordLevelEventListener;
});
