No it did not have a no-args constructor. I added one and everything 
works now. I could have sworn it worked before. I should know this but, 
if you do not have any constructors in your classes is a default no-args 
one made for you. And if you have other constructors in your class but 
no no-args constructor then there is no no-args constructor made for 
you? I know its something like that. That would explain why it stopped 
working. I just added a constructor with args to the User class.

Thanks,
