Are the ActionLinks being processed?
No they're not :(. The onProcess method does not appear in the logs,
nor is the action method called.
The PageLink of course does not need this since there's nothing to
process there.
Are the ActionLinks controls
registered with a parent container or page?
Yes I added("registered" with addControl() ), the ActionLink controls to
the page :(.
I created in Click Examples a page - ActionLinkTreePage that is
reproduction the problem you mention (see attachment - the example is
based on the PageLinkTreePage).
