Reason: <F001Registration 0xfd3a3b> valueForKey(): lookup of

I have tried several things to fix this issue to no avail:
1) I've checked to make sure all of my classes and attributes
match between EOModeler and mysql.
2) I've rebuilt all of my .java classes and exported them to my
workspace
3) Deleted and rebuilt my build folder
The reason states that the F001Registration component has an
e001Event key that its Java class doesn't implement. This could
occur if you created an e001Event key in WebObjects Builder which
you bound to an attribute of a dynamic element, for example, but
you neglected to add a protected or public instance variable or
public e001Event accessor method to F001Registration.java.
It also might just be a spelling mistake. It seems a little odd to
have an *e*001Event on the *F*001Registration page. In any event,
Art is correct that you have been looking for the problem in the
wrong place. Careful reading of error messages is vital to effective
debugging.
