OK, where are you getting the exception? Open the call-stack view.

EDIT: I see your problem.

You declare these arrays:

private BasicEditField sub[];
private ObjectChoiceField crd[];
private ObjectChoiceField grd[];

But you never allocation storage for them.

You need this in your constructor:

sub = new BasicEditField[<whatever size you want>]


Did you get that Java book?
