Hi
I'm trying to add exception handling to one of my pages but I'm a little bit
stuck.
I've got a page that loads an entity using a DAO (Hibernate, Spring). In
case of an error due to optimistic locking I want to reload the page with
the updated entity and display a message on a feedback panel.
The onSubmit() method of my button looks like that:
@Override
public void onSubmit() {
// save store to DB
try {
storeDao.saveOrUpdate(store);
setResponsePage(StoreTablePage.class);
} catch (StaleObjectStateException ex) {
store = storeDao.retrieve(store.getId());
error(new
StringResourceModel("form.error.optimisticLockingException", this,
null).toString());
}
}
What is weird is that when I write "catch (StaleObjectStateException ex)"
then the exception is somehow intercepted and the catch section is never
reached, instead a stack trace of the exception is shown. When I change it
to "catch (Exception ex)" then it works as expected. At the moment I'm
running the Wicket application in development mode.
Am I missing some important concept about exceptions in Wicket?
Bye,
Florian
