I have a User object with an email() method. This is the standard

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.
Is it null if you type something into the email field on the form?
If you don't type in anything, WO makes the value a null, not an
empty string. Is that where you are getting hung up.
Darn. I guess what you don't know can hurt you. I was expecting the
empty string and the function declared a string as it's return value,
so it seems odd to me that it's not, but at least I know now. I guess
this is one of those semantic gotchas.
Thanks Chuck.
