No Method Signature - initQuery error after VO Substitution

Question

Hi All,
I have done a VO Substitution for "NewBankAccountVOImpl". Below is the exact Requirement,
iReceivables -> Query for a given Customer -> Go to accounts Tab -> Try to Pay off an invoice -> You get an option choose Payment Method as "New Bank Account" ->
Now there are three field Routing Number, Account Number and Account Holder
I need to restrict Account Number to minimum three characters. In 11.5.10 Oracle do not have this validation.
So I checked out the place where the Routing Number and Account Number Validation happen i.e "NewBankAccountVOImpl" and extended the same to custom VOImpl and copied all the standard code to my custom code as below,
package mercury.oracle.apps.ar.irec.accountDetails.pay.server;

I did compile the Java File and also the JPX import. It was all successful. I tested the code and it worked as expected. Now I see an exception on the page when I click the Pay button stating "No Method Signature No Method Signature - initQuery".
The error do not come when I take out my substitution. Any one know what might be the reason for above issue. I have no idea why all of a sudden it stopped working and checked all standard filles but none got changed.
Any pointers towards to resolve the same would be appreciable.
Thanks in Advance,
Veerendra

Uma,
try to delete all class files, recompile and run! Also, check if any CO is not extended other than from OAControllerImpl, although it would not be generally.
