[T5] PageLink cannot be disabled?
Just discovered that PageLink doesn't have a disabled parameter. That's
a pity. Any ideas how to deal wit this?
Thanks,
Alexander

[component snipped]
Semi-OT question :)
Wouldn't a disable PageLink component be better of to render the
link-text without the <a></a> instead of not render anything?

Put this in your components directory and it will override Tapestry's
PageLink component unless your classes import the corelib type.
(I'll submit a JIRA.)
Cheers,
Nick.

write a mixin that is able to render a pagelink that is disabled and
attach it to your pagelink component.
