Enable DeltaManager to replicate PageTable in Sessions
- 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
