Re: Can't Get IAuthorizationStrategy Working
I guess we're out of luck. Component#canCallListenerInterface() doesn't
exist in 1.4.x AbstractLink#isLinkEnabled() is final, so we can't
override it.
Will have to redesign our form class. Sigh.

Hi,
Not certain about 1.4.x but in 6.x if a parent component is disabled then
all its children are disabled as well. For AbstractLink there is a special
#isLinkEnabled() method which combined with
Component#canCallListenerInterface(Method) can make the link enabled even
if any of its parents is disabled.
Good luck!

some reason, when the parent form is disabled, and the link is enabled,

Can anyone see what we're doing wrong?
We use Wicket 1.4.17 (no option to upgrade due to corporate framework
