It looks like you have told EOF that your firstName and lastName cannot be NULL.
After your form is posted, WO will call validateTakeValueForKey (maybe a bit different spelling) which 
will do the validation for every key in your EO.

Once you save your EditingContext those validating is done again.

Set a breakpoint in your validation code and print the back trace.
