---------------------------------
Summary: Simplify PublishingService, deprecate concept of payload
factories.
Key: ISIS-1370
URL: https://issues.apache.org/jira/browse/ISIS-1370
Project: Isis
Issue Type: Improvement
Components: Core
Affects Versions: 1.12.0
Reporter: Dan Haywood
Assignee: Dan Haywood
Priority: Minor
Fix For: 1.13.0
Most PublishingService implementations (to date) only require the metadata
(action invocation or domain object identity) to publish their events; the
notion of the payload (to eagerly assemble information for the downstream
subscribers) seems less useful.
This ticket is therefore to deprecate the
PublishingService#publish(EventMetadata, EventPayload), and replace with
PublishingService2#publish(EventMetadata).
In addition, the framework will be changed so that for the existing API taking
a payload, this will now just be passed in as null.
This also means that @DomainObject#publishingPayloadFactory() and
@Action#publishingPayloadFactory() attributes are deprecated (will have no
effect).
