I have a User object with an email() method. This is the standard
boilerplate generated by EOModeler from my User table.
public String email() {
return (String)storedValueForKey("email");
}
I have a registration page with a field on the page bound to
user.email and a method called fieldsValidate(). When I get to the
line ckEmail = user.email(); I get a null pointer exception.
user.email() is returning null. I am not sure why? The
registerNewUser method works fine if I take out the fieldsValidate().
Can someone hit me with the clue-by-4.
Thanks,
Kevin
