Yeah. That's because that field is not part of the base class of the ConnectionStatusDTO:
http://activemq.apache.org/apollo/versions/1.0-beta3/website/documentation/api/apollo-dto/org/apache/activemq/apollo/dto/ConnectionStatusDTO.html The StompConnectionStatusDTO extends the class and adds that field in. Unfortunately, the JOSQL library which we are using to query/filter the fields only work against the base classes and the the sub classes. I'll have to move the field to the base class.
