Field Detail

vecAdd

protected transient Vector vecAdd

Counter that is incremented when a new list of objects is loaded. Incremented by select, setSharedHub, and when detail hubs list is changed to match the master hub's activeObject.
This can be used to know if a hub has been changed without requiring the set up of a HubListener.

This is used by JSP components to know if a frame should be updated.
