What is needed for Netbeens 6.8 to recognize Apache Click @Bindable annotation?

[vxc vxc]

Hello,

What is needed for Netbeens to recognize @Bindable annotation?

I get:

cannot find symbol
symbol: class Bindable

Source code:

package clicktest.page;
public class HomePage extends BorderPage
{
   @Bindable protected String title = "Home";
}

Thank you!
