How to clear errors related to class (form) caused by onValidate()?

In wicket 1.4 I used to clear errors that were caused by onValidate() method in specific form. Unfortunetly after migrating to wicket 6 order of method execution has changed or my code was has been written poorly. So I have ajax button, similar to this:

    final AjaxFallbackButton submitButton = new AjaxFallbackButton(PREFIX + ".submit", new I18nModel(title), panelForm) {

        @Override
        protected void onSubmit(AjaxRequestTarget target, Form<?> form) {
            // submit method
        }

        @Override
        protected void onError(AjaxRequestTarget target, Form<?> form) {
            addPanel.setProcessingEnabled(true);
        }
    };

    submitButton.add(new AjaxFormSubmitBehavior(panelForm, "onclick"){
        @Override
        protected void onEvent(AjaxRequestTarget target) {
            addPanel.setProcessingEnabled(false);
            super.onEvent(target);
        }
    });

The addPanel is pointing at class that contains form where I want to clear errors. So in this class I'm adding form like this:

    panelForm = new Form<B>("panelForm", new PrefixedCompoundModel<B>(getDefaultModelObject(), PREFIX)) {
        @Override
        protected void onValidate() { 
            super.onValidate();
           if (!processingEnabled) {
                Session.get().getFeedbackMessages().clear(new ContainerFeedbackMessageFilter(this));
            }                              
        }

        @Override
        protected void onError() {
            UiUtils.refresh(panelForm);
        }
    };

Variable processingEnabled is true by default. I was only changing it when above ajax button has been clicked. It used to go first to my behavior and then to onValidate in form above. Right now it goes: onValidate -> onError(panelForm) -> behavior -> onValidate -> onError(panelForm) -> onError(button). I would like to pass processingEnabled argument before onValidate or clear all errors related to this form in onError method. Thanks for feedback.

Session.get().getFeedbackMessages() gives you the feedback messages in the session only - but since Wicket 6 feedback messages are stored along with their components:
