So, I think the MessageFactory class you have is not needed. You can use Seam
org.jboss.seam.core.FacesMessages class instead.
Below you can see an example I have:
|
| @Name("converters")
| public class Converters {
|
| @Transactional
| public Converter getRoleConverter() {
| return new Converter() {
|
| @Transactional
| public Object getAsObject(FacesContext facesContext,
UIComponent uiComponent, String string) throws ConverterException {
| Role role = ((EntityManager)
Component.getInstance("entityManager")).find(Role.class, string);
| if (role != null)
| return role;
| else {
| FacesMessage message =
FacesMessages.createFacesMessage(FacesMessage.SEVERITY_ERROR,
"Common.error.selected_NotFound", null, "");
| throw new ConverterException(message);
| }
| }
|
| public String getAsString(FacesContext facesContext,
UIComponent uiComponent, Object object) throws ConverterException {
| return ((Role) object).getName();
| }
| };
| }
|
| }
|
|
Common.error.selected_NotFound is a key in the messages.properties.
HTH.
