TagTester and AJAX

Hi,

i try to test my manipulated html tags with tagtester. it works fine, if i
submit the form via formtester. but when i try to set value to request 
directlyand submit via ajax-button the tagtester failed - the attribute wasn't
updated.

her the code: - a simple ajax submit example where text
in real live i doesn't submit the value via button. here its a direct 
key-event. that's the reason, why i can't use the formtester in 
this case. the rest works fine.


thanks alex

final TextField tf1 = new TextField("tf1", new PropertyModel(this, "value")){
	@Override
	protected void onComponentTag(ComponentTag pTag) {
		super.onComponentTag(pTag);
		if (isRequired()) {
			if (getInput() == null || 
				getInput().equalsIgnoreCase("")) {
				pTag.put("class", "abc");
			}
		}
	}
        	
        };
        tf1.setRequired(true);
        final Label lbl1 = new Label("lbl1", new PropertyModel(this, "value"));
		Form lForm = new Form("form");
		final FeedbackPanel lSetOutputMarkupId = (FeedbackPanel) new

				pTarget.addComponent(lbl1);
