I understand that the ManagedService has to handle the missing number property. What is the expected way for this to happen?
Is each configuration considered to be complete and self-contained, so the answer below would be number:7? If this is the case, then the ManagedService is reset to the default configuration before the passed configuration is applied. Is each configuration considered an update to the current configuration, so the answer below would be number:1? If this is the case, then the ManagedService is NOT reset before the passed configuration is applied. At first, I thought it was the latter (inferred by the name of the update method). However, the few examples I've seen appear to implement the former. Looking at the source code also suggests the former since Configuration.update() calls Configuration.configureFromPersistence() and Configuration.update(Dictionary) simply replaces the Dictionary used for persistence.
