[jira] Commented: (MSITE-608) aggregating breadcrumb behavior disappears in the presence of a menu in the parent

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.
