resolveData.deltaPacket
Description
Property; contains a description of the changes to the DataSet component. This property is of
type
deltaPacket and receives a delta packet to be translated into an XUpdate packet, and
outputs a delta packet from any server results placed in the
updateResults property. This
property provides a way for you to make custom modifications to the XML before sending the
updated data to a connector.
Messages in the
updateResults property are treated as errors. This means that a delta with
messages is added to the delta packet again so it can be re-sent the next time the delta packet is
sent to the server. You must write code that handles deltas that have messages so that the
messages are presented to the user and the deltas can be modified before being added to the
next delta packet.
The DataSet component’s
deltaPacket property should be bound to this property so that
when
DataSet.applyUpdates() is called, the binding copies it across and the resolver creates
the XUpdate packet.
