> When using Tomcats o.a.c.h.t.SimpleTCPCluster to replicate Sessions in a Tomcat cluster the o.a.c.h.s.DeltaSession is the default implementation which handles session replication
> Unfortunately, to calculate its deltas, it assumes that session attributes are only modified by calling accessor methods (i.e. DeltaSession.setAttribute(n,v))
> Modifying an existing Object (e.g. wicket's PageTable) in place of the current session, would not trigger a delta replication
> To make Wicket work with SimpleTCPCluster and DeltaSessions, we will always rewrite the PageTable into Session by calling setAttribute
