Hi
This is inline with my previous question :
We have a used *HasDataEditor* to populate out *CellTable*, *but now we are
facing a* problem with driver.flush() part, we trying to to driver.flush()
and click of a save button, below you can find the code snippet, it throws
an exception on doing driver.flush() ;
@UiHandler("save")
void onSaveClick(ClickEvent event) {
save();
}
public void save() {
Contacts contacts = driver.flush();//Line No 130
System.out.println(contacts.getContactList());
}
And the exception is :
08:51:37.503 [ERROR] [customer] Uncaught exception escaped
com.google.gwt.event.shared.UmbrellaException: One or more exceptions
