Hi Chris,

The current state of that class is 'highly experimental'. It can be used for 
demos, but I know it has some bugs that I'm not certain how should be solved 
(mostly around new intermediate nodes arriving), but I haven't had time to 
work on it in a long time. 

It looks like the version in proxymodeltestapp is slightly more up to date, 
but I also noticed a difference wrt mapToSource in the akonadi_next version 
which should maybe be in the class.

It is surprising that it doesn't work for you in even the simplest case. Did 
you try running the proxymodeltestapp and trying the 'reparenting PM' tab? 
That works for me.

All the best,

Steve.
