* This controller is used in order to respond to AJAX calls that require message code list, message
* entities and post those entities after form submission. Typical scenario is that entity list is
* loaded using {@link #getEntityList()} and user can select one to translate. Upon selection, exact
* entity must be retrieved using {@link #getEntity(String, String)} in order to fill in the form.
* Upon form sumission, another AJAX call submits form values and
* {@link #postTranslation(String, String, String)} updates the message.
