One thing is sure: this can't work in 1.x, since
the title is displayed
before the content is parsed, so the velocity variables get their values
after you display the title.
In 2.4 the title is printed after rendering the content, so it does
work, but the breadcrumbs are still printed before the content, so that
fails.
So, to see if Velocity does work in your version, try using $doc.author
as the title and see what gets printed. If it's the literal
'$doc.author', then velocity isn't interpreted. If it prints a username,
like 'XWiki.Admin', then it is interpreted, and the problem is that
you're trying to use not-yet-defined variables.
I think the situation is clear and Velocity does work here. As you said
and coming back to the example...
http://core.ebiotic.net/bin/Draft/VelocityConcatenation
... the variables defined in the content of the document are correctly
printed in the title but not in the breadcrumbs. It works as expected
because, as you said, the title is printed after rendering the content
but the breadcrumbs are printed before that.
As what I'm looking for is to include in the breadcrumbs variables
defined in the content or values of properties of classes instantiated
in the current document, I think the only solution is to get the
breadcrumbs printed after the contents.
Please, does it make sense for you? Could this be possible/advisable
with the current rendering architecture?
Thanks!

The same in a 2.4.x installation... clearly
I'm failing to understand
something. I'll be back to this issue in a couple of hours!

Thanks!
