i see. i guess i assumed that the Link knows about the page it's linking
from setResponsePage() in onClick().
so, in this use case is there any difference whether to override linksTo()
or isEnabled()? i think overriding isEnabled() is more generic, if latter
i'll need to add more logic to disable the link this will be the place to do
it. anything else?
Thanks

How would the Link know to which page it is linking? You need to provide
protected boolean linksTo(final Page page)
See the code for Link#isEnabled():
/**
* @see wicket.Component#isEnabled()
*/
public boolean isEnabled()
{
// If we're auto-enabling
if (getAutoEnable())
{
// the link is enabled if this link doesn't link to the
current page
return !linksTo(getPage());
}
return super.isEnabled();
}
