AbstractBehavior problem after comonent re-render

Hi!

I added simple simple behavior:

public class XDateField extends DateTextField {

    public XDateField(String id, IModel model) {
        super(id, model, "yyyy-MM-dd");

        add(new AbstractBehavior() {
            @Override
            public void onRendered(Component component) {
                Response response = component.getResponse();
                response.write("\n&lt;a href=\"#\" onclick=\"changeDate('" +
component.getMarkupId() + "', -1)\"&gt;(DEC)&lt;/a&gt;");
            }
        });
        add(new DatePicker());
    }
}

It is rendering ok. But when the component is re-rendered via ajax
(target.addComponent(dateTextField))
my behavior is re-added. After each re-render my link looks like this:
[component] (DEC)(DEC)(DEC)(DEC)... [calendarIcon]


How to fix it?

Thanks in advance,
Artur

Ok, I fixed it. I needed to remove it if it was rerendered again with ajax:

	private class ChangeDateBehavior extends AbstractBehavior {

		private Component component;
		private int days;

		public ChangeDateBehavior(int days) {
			this.days = days;
		}

		public void renderHead(IHeaderResponse response) {
			if (AjaxRequestTarget.get() != null) {
				final String javascript = "var e = Wicket.$('" + getMarkupId() +
						"'); if (e != null && typeof(e.parentNode) != 'undefined')
e.parentNode.removeChild(e);";
				response.renderJavascript(javascript, null);
			}
		}

		@Override
		public void onRendered(Component component) {
			Response response = component.getResponse();
			response.write("\n&lt;a id=\"" + getMarkupId() + "\"href=\"#\"
onclick=\"changeDate('" + component.getMarkupId() + "', " +
Integer.toString(days) + ")\"&gt;&lt;&lt;/a&gt;");
		}

		@Override
		public void bind(Component component) {
			this.component = component;
		}

		public String getMarkupId() {
			return component.getMarkupId() + "--cd";
		}

	}

Can you just override isTemporary()?
