Abstract
A method provides a synchronization cycle for updating changing component property values at a client and a gateway system. When the client receives a change to a value, it saves the change as a pending value in association with an existing value for the component property. The client sends a set of changes and an identifier to the gateway system. The gateway system updates its component property values accordingly. The gateway system accumulates changes to property values including changes from the client and other changes received via data bindings or other methods. The gateway system sends a message to the client including the accumulated property value changes and the identifiers associated with client-provided value changes that have been applied. The client updates its component property values according to the accumulated changes and removes references to pending values that are associated with identifiers sent back by the gateway system.
