gui builder null pointer exception

I figured it out. I did not see anywhere where I could compile the form.

Hello;

I'm starting to use the gui builder. I read the docs and viewed the
training videos. I can layout a form, bind, and write code. I even
downloaded the Subscribe example. When I compile and run it, I get
NullPointer exception.

I don't know what I'm doing wrong. It is unintuitive because I don't
know how the bind fields get initialize. I know when my main method
runs I get a null pointer.

What am I doing wrong?

Thanks for your help.
