Stefan, Sorry for getting back late. I've narrowed down part of my issue here. It appears when my application starts up, it creates several objects of the same type inside of Window's configInit (one object per window). It seems only one object is registered properly to receive updates from the system (thus receiving the notifyNewHeadVersion call).
When I try to map in the object using VERSION_HEAD instead of the default, the
application hangs during the initialization. I instead made use of my delayed
synchronization system to explicitly call sync() after the application is fully
initialized, which seems to kick in the necessary state. Afterwards all
objects stay up to date as expected (they all have their notifyNewHeadVersion
function called). If you still want, I can try and put together a small demo
of this problem.
Thanks for your help,
Matthew
