Error Message Not Getting Removed

[jpalmer1026]

I have a form that's using an AjaxSubmitLink to show / hide a panel. I have overriden the onError() method to add a feedbackPanel to the page to display any error messages that may exist. The problem I'm having is the error messages are remaining on the screen even after the problem is fixed. Any suggestions? My code is as follows:

final AjaxSubmitLink verifyPinLink = new AjaxSubmitLink("verifyPinLink") {
            @Override
            public void onSubmit(AjaxRequestTarget target, Form form) {
                Declaration declaration = (Declaration) form.getModelObject();
                ParcelIdentification pid = declarationService.findParcelIdentification(declaration.getPin());
                if (pid == null) {
                    form.error("No PIN found for PIN " + declaration.getPin());
                } else {
                    InitiateDeclarationVerifyPanel decVerifyPanel = new InitiateDeclarationVerifyPanel("verifyPanel", pid);
                    parent.addOrReplace(decVerifyPanel);
                    parent.setVisible(true);
                    this.setEnabled(false);
                    pinText.setEnabled(false);
                    reenterPinLink.setVisible(true);
                    button.setVisible(true);
                    target.addComponent(this);
                    target.addComponent(parent);
                    target.addComponent(reenterPinLink);
                    target.addComponent(button);
                    target.addComponent(pinText);
                }
            }

            @Override
            public void onError(AjaxRequestTarget target, Form form) {
                target.addComponent(feedback);
            }
        };
