Using SimpleAttributeModifier

[Anna Simbirtsev]

Hi,

I am trying to use SimpleAttributeModifier to make an ADD MORE link
invisible once the maximum number of text fields that it adds have been
reached.
But I can not get it to render the link component.

My code:

 addLink = new AjaxSubmitLink("addRow", form) {

            private static final long serialVersionUID =
8103461308100688184L;

            @Override
            public void onSubmit(AjaxRequestTarget target, Form<?> form) {
                 if (tech_count < max_tech_contacts) {
                     lv.getModelObject().add(new String());
                     if (target != null) {
                         target.addComponent(
techPanel);
                         tech_count++;
                     }
                     if (tech_count >= max_tech_contacts)
                         addLink.add(new SimpleAttributeModifier( "style",
"display:none"));
                 }
            }
  };
 addLink.setDefaultFormProcessing(false);
 form.add(addLink);

I am guessing it adds style="display:none" to the addLink, but does not
render it again, so the link is still visible.

Thanks,
Anna
