Workaround for deprecated Liferay "Forms" headless API

Issue

• The Liferay "Forms" headless API is deprecated.
  It is discussed in detail here: https://liferay.atlassian.net/browse/LPS-125528
• The users could still want the functionality that was provided by these endpoints.

Environment

• Version: Liferay DXP 7.4 Quarterly Releases

Resolution

•  You can use both the Java API or the JSONWS API.
  See the following examples:
   
  You can access the form values (with Java API) as follows:
  

  List<DDMFormInstanceRecord> ddmFormInstanceRecords = DDMFormInstanceRecordServiceUtil.getFormInstanceRecords(formId); 
  
  for (DDMFormInstanceRecord ddmFormInstanceRecord : ddmFormInstanceRecords) {
         DDMFormValues ddmFormValues = ddmFormInstanceRecord.getDDMFormValues();
  
         for(DDMFormFieldValue ddmFormFieldValue : ddmFormValues.getDDMFormFieldValues()) {
      	   String name = ddmFormFieldValue.getName();
      	   Value value = ddmFormFieldValue.getValue();
      	   
      	   for(Locale locale : value.getAvailableLocales()) {
      		   String valueString = value.getString(locale);
      	   }
         }
  }

  You can also access the ddmFormInstanceRecords (with JSONWS API) as follows:
  

  curl http://localhost:8080/api/jsonws/ddm.ddmforminstancerecord/get-form-instance-records \
  -d ddmFormInstanceId={formId}

  Note, that here, the result does not provide the field values.
