Hi Lukas,
Two things:
1) breadcrumbs always get appended, you cannot override or remove a
breadcrumb that has been added in a parent
Yes, this explains why we have breadcrumb trails like the following.
Apache > Maven > Apache Maven Site
Here, both "Maven" and "Apache Maven Site" point to the same URL.
2) identical breadcrumbs are ignored
In your first case above, you are trying to add the same breadcrumb
(same name, same href) again that is already defined in the parent, so
according to 2) it is ignored and you only get the parent breadcrumbs.
In your second case the child breadcrumb is appended according to 1) so
you get 3 (2 parent + 1 child) breadcrumbs.
Interesting that the notion of equality is based on *both* @href and
@name; I would have expected it to only consider the former. (But that
doesn't solve my problem, of course.)
This is the currently expected behavior. The fact that one cannot
override or remove breadcrumbs is annoying, you might want to file a
feature request for it.
Done: <http://jira.codehaus.org/browse/MSITE-582>
Thanks for you explanation.
Andreas
