I have been using the component assigned messages in the following manner:
| @IfInvalid(outcome = REDISPLAY)
| public String create() {
|
| if(poCoupling.getSize().getId()==null) {
| facesMessages.add("size", new FacesMessage("Size required"));
| }
|
| if(poCoupling.getGrade().getId()==null) {
| facesMessages.add("grade", new FacesMessage("Grade required"));
| }
|
| if(!facesMessages.isEmpty()) return null;
|
| poCouplingDAO.makePersistent(poCoupling);
|
| return "nothing";
| }
|
I added the following method to FacesMessages in order to check to see if I
should redisplay the form.
| public boolean isEmpty() {
| if(facesMessages.size()==0 && keyedFacesMessages.size()==0) {
| return true;
| } else {
| return false;
| }
| }
|
I need to check for the presence of an id in my objects because they are
connected to a dropdown and if the id is null I get an
org.hibernate.TransientObjectException.
Is there an existing way to do this? If not, how do you feel about adding this
funtionality?
