-------------------------------------------------------------
Thanks for catching this.
Perhaps we can implement it a different way. We can add a new
{noformat}
public RMStateUpdateAppEvent(ApplicationStateData appState, boolean
notifyApplication) {{noformat}
constructor to RMStateUpdateAppEvent and a new method
{noformat}
public void updateApplicationState(ApplicationStateData appState, boolean
notifyApp) { {noformat}
to RMStateStore, then call this new method in
RMAppImpl#AttemptLaunchedTransition instead of
updateApplicationState(ApplicationStateData). Previously we send an event on
every app launch; with this approach we can avoid sending these unnecessary
events only to ignore them later.
Thoughts?
