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!

Can't Get IAuthorizationStrategy Working
We have a use case which requires an enabled link inside a disabled form.
The form being disabled is based on user's security role, but the link
being enabled depends on the results returned from a separate database
query. Thus, we might have a disabled form, but an enabled link, or vice
versa. Our link class (below) implements IAuthorizationStrategy, but for
some reason, when the parent form is disabled, and the link is enabled,
the onClick() method is not called.
Can anyone see what we're doing wrong?
We use Wicket 1.4.17 (no option to upgrade due to corporate framework
constraints).
