AjaxLink throws WicketRuntimeException

[Tim Squires <wm...@tnwdb.com>]

Hi,

I have an AjaxLink that displays a ModalWindow onClick:

        AjaxLink executorLink = new AjaxLink("show executor") {
            public void onClick(AjaxRequestTarget target) {
                logger.debug("show the executor details window for will "
                        + will);
                executorModalWindow.show(target);
            }
        };
        // Don't display the executor link if this is read only.
        executorLink.setVisible(!readonly);
        add(executorLink);

with html

<a href="#" wicket:id="show executor">executor...</a>

The first time this link is clicked, a WicketRuntimeException is thrown.

WicketMessage: component wills list:wills list:1:will details:show
executor not found on page

See below for full stack.  If I then go back (right click->back) and click
the link again, the modal window is displayed.

Has anyone come across this before?  What have I missed?

Wicket 1.3.1
Tomcat 6
JDK 1.6

Thanks for your help,
Tim
