> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Reporter: Keith Wall
> Assignee: Rob Godfrey
>
> I notice that when updating a single attribute of an object through the Web
> Management UI (for instance, a port's binding address attribute), the
> underlying store is written many times. Further investigation showed that
> there is a separate save being generated for every attribute sent from the UI
> (which includes values that have no changed).
> There is an expression in AbstractConfiguredObject#changeAttributes that
> appears to want to prevent unchanged values causing set attribute events, but
> a logic defect means this is not the case.
