The main problem is that applyAndClear() is not transitive, i.e. changes
that are applied are not added into the thread's ChangeList. AFAIR we
used to have an option for that, but I can't find it right now.
Thus you have to do both the things you mention: you need to merge the
changes into the current CL (so that they are transfered to the cluster
nodes), and applyAndClear() them to get the new data over into the right
aspect.
Hope it helps
Dirk
