selected links in a menu

[Fernando Wermus <fe...@gmail.com>]

Hi all,
    I have a menu that it structure is the following:


1. for the link selected

<ul id="someId">
     <li>
        <em> selected item </em>
    </li>
....


2. for the link not selected

<ul id="someId">
      <li>
          <em>
             <a> item not selected</a>
          <em>
      </li>
...


I programmed this with a border that renders the <em>, but I need make
invisible the border, but not the anchor to get the first case.

I tried:

border.setVisible(false);
border.getBodyContainer().setVisible(true);

and I got an error:

at java.util.AbstractList$Itr.remove(
AbstractList.java:356)
at org.apache.wicket.Page.checkRendering(Page.java:1139)
at org.apache.wicket.Page.renderPage(Page.java:921)
at
org.apache.wicket.request.target.component.BookmarkablePageRequestTarget.respond(BookmarkablePageRequestTarget.java:240)


Which is the best way to achieve this?

I supposed that if a decorator didn't render it would mean the body would
still be rendered - it is a decorator, not a classic container.

thanks in advance

simply disabling the link, calling setenabled(false), will get you
there. also see link#setbefore/afterdisabledlink(string markup) which
looks like you may want to set to ""
