Невозможно удовлетворить @ org.simpleframework.xml.Element в поле 'id'

Question

Я использую simpleXML для анализа XML, возвращенного с сервера SOAP.

Ошибка:

java.lang.RuntimeException: org.simpleframework.xml.core.ValueRequiredException: невозможно удовлетворить @ org.simpleframework.xml.Element (data = false, name = идентификатор, required = true, type = void) в поле 'id' public java.lang.String be.test.model.response.ContentMetadataResponse $ Body.id для класса be.test.app.core.service.model.response.ContentMetadataResponse $ Body в строке 1
