[Building Sakai] Building the site's resources into a tree table using Apache Wicket

[Suparoek Leesaen]

Hi all,

I need to build a hierarchy of resources in different sites using Apache
Wicket. Since ContentHostingService#getAllEntities return a linear list of
ContentEntities, what do you think would be the best approach of organise
them into parents and children? Thanks in advance

Kind regards
