Herve Boutemy commented on MSITE-608:
-------------------------------------
I just tested your project, and I don't understand: I don't see any difference
when the menu is defined or not (which honestly is a Good Thing: a menu should
not have any impact on breadcrumbs).
The child breadcrumbs are always: Maven > Breadcrumb TC Module > About
And they are not wrong: if they lack a breadcrumb to visit the parent, it's not
a bug, it's a feature :)
The feature is: when a descriptor defines explicitely some breadcrumb item, no
automatic breadcrumb item is added
I found it reading the inheritance code, and it's IMHO logical since it permits
you to override automatic breadcrumbs with whatever you want (choose name and
href)
[Decoration Model
documentation|http://maven.apache.org/doxia/doxia-sitetools/doxia-decoration-model/]
needs improvement to explain inheritance
I'll work on it when working on DOXIASITETOOLS-62, since inheritance algorithm
will become more flexible, then absolutely needs clear documentation
but before that, if you're able to start something, that would be great

> This may turn out to belong in Doxia. I don't know.
> The attached project consists of an aggregating project and its module. The
> breadcrumbs in the module are, I claim, wrong -- they lack the breadcrumb to
> visit the parent.
> If you remove this menu:
> {code}
> <menu name="tc">
> <item name="Home" href="index.html"/>
> </menu>
> {code}
> from the parent's src/site/site.xml, all is well. Once it's here, the
> parent-level breadcrumb is omitted.
