Hi,
The DataProvider method is only called when the table needs the data, in
this case at render time. So the following should work:
public void onInit() {
table.setDataProvider(new DataProvider() {
public List<Customer> getData() {
if (form.isValid()) {
return getCustomerService().getCustomers();
} else {
return new ArrayList(); // <-- Return empty list
}
}
});
}
regards
Bob
