please help me to solve the problem?
after submitting and page redisplayed, username can be saved, but langs lost
values added by submit method.
@Property
@Persist(PersistenceConstants.FLASH)
private String username;
@Property
@Persist(PersistenceConstants.FLASH)
private List<String> langs;
void onActivate() {
if (langs == null) {
langs = new ArrayList<String>();
}
}
void onSubmit() {
langs.add("en");
}
