Sorry for being the redundant. I downloaded the CP03 source and have a question about the failoverOnNodeLeave attribute. The JMX interface denies changes to the value if the PostOffice service is started. I think it would be helpful to be able to change this attribute after the service is started. When I looked through the PostOffice service implemenation, I noticed the attribute is written in the constructor and read only once in one method, nodesLeft(). Other than as a basic service-level policy decision, I don't understand why this particular attribute cannot be changed at run-time. Is there some other behavior I'm not seeing?
