[jira] [Created] (ISIS-803) Replace lifecycle methods with
additional EventBus events.
Dan Haywood created ISIS-803:
--------------------------------
Summary: Replace lifecycle methods with additional EventBus events.
Key: ISIS-803
URL: https://issues.apache.org/jira/browse/ISIS-803
Project: Isis
Issue Type: Improvement
Components: Core
Affects Versions: core-1.5.0
Reporter: Dan Haywood
Assignee: Dan Haywood
Fix For: core-2.0.0
This issue is to remove a feature that is only partly implemented in the JDO objectstore, namely the lifecycle methods.
Jeroen and I were discussing this, and think they are possibly an anti-pattern since they tend to lead to fragile code.
Rather than have the object "pushing" changes to others, it would be better if an event were broadcast via the EventBus. That way a subscribing service could pull appropriate changes and do whatever is necessary.

Fair enough... I've updated the ticket with these points.

Hi, Dan.
I think that the lifecycle PostsXXX events were still incomplete.
There's one thing I don't have clear enough from your comments.
Also, we cannot impede that a user use the JDO or JPA standard methods. So, despite they are a not good practice, we at least should "support" when the standard JDO (JPA in the future) lifecycle methods are used (i.e., by "detecting" the changes on those domain objects, if that's used by Isis; but not sure if there's something special to do by Isis).
