[xwiki-devs] Inconsistency between the breadcrumb and the document tree on a subwiki

Hi devs, I recently discussed with Edy about how the breadcrumb should look and there may be an inconsistency with the hierarchy displayed by the document tree. Breadcrumb on the main wiki: Home Icon (pointing to the main wiki home page) / MDoc1 / MDoc2 / ... / MDocX Breadcrumb on a subwiki (that has only global users): Home Icon (pointing to the main wiki home page) / Subwiki Pretty Name (pointing to the subwiki home page) / SDoc1 / SDoc2 / ... / SDocX After seeing the breadcrumbs both on the main wiki and on a subwiki the user might think that the document MDoc1 and the wiki "Subwiki Pretty Name" are on the same level: both children of the main wiki. Next if the user tries the document tree macro using: {{documentTree showWikis="true" /}} he will notice that "Subwiki Pretty Name" is not actually a child of the main wiki but a top level node (a child of the "farm"), on the same level with the main wiki. Can this be considered as an inconsistency? In our model (e.g. document reference) there is no hierarchy between wikis, although, as Edy pointed out, there are places where we consider the main wiki to be the "parent" of the subwikis (e.g. in the authorization module, by inheriting access rights from the main wiki). WDYT? Is the main wiki the parent of the subwikis or just a sibling? Should the breadcrumb be synchronized with the tree? Thanks, Marius
