State change

A case record exists in the following states:

State	Description
Start	Every new applicant in the system begins at this initial state

Reviewing	The case worker is reviewing the applicant's record
Decision	The case has been reviewed and the business is taking a decision
Accepted	The case has been accepted and the applicant is being notified
Rejected	The case has been rejected and the applicant is being rejected

All these business requirements are captured in Finite State Machine.

Controller code

By now the code should be familiar to you. The controller method changeStateCaseRecordDialog() in NewTaskModalController is as follows:

$scope.changeStateCaseRecordDialog = function (caseRecordItem) {
    /* Copy  */
  $scope.caseRecord = {
    id: caseRecordItem.id,
    firstName: caseRecordItem.firstName,
    lastName: caseRecordItem.lastName,
    dateOfBirth: caseRecordItem.dateOfBirth,
    country...
