Re: audit trail - would this work?
Would this work?
Add an optional element (or attribute) to entity field elements
called audittrail. The presence of the audittrail element tells the
entity engine that you wish to record changes to the field in an
audittrail table.
<entity ...>
<field ...><audittrail/></field>
...
</entity>
Separate entities could be created representing each field type, so
the entity engine could record the changes to the field in a field of
the same type:
<entity name="auditIdNe" ...>
<field name="beforeValue" type="id-ne".../>
<field name="afterValue type="id-ne" .../>
</entity>
<entity name="auditIdVlong" ...>
<field name="beforeValue" type="id-vlong".../>
<field name="afterValue type="id-vlong" .../>
</entity>
<entity name=... repeat for all the data types
Any ideas/feedback?

I'm interested in developing this. It looks like a good project to
help me to deepen my understanding of the ofbiz internals.

Re: audit trail - would this work?
Posted by "David E. Jones" <jo...@hotwaxmedia.com>.
If I understand you right, this sort of thing has been discussed
before, and wouldn't be terribly complicated to implement as an
extension to the Entity Engine, but it can introduce a huge amount of
overhead for the app server and database (if there are very many
fields to do this with).
What you'd basically be doing is keeping a revision history of a set
of fields across various entities. A few thoughts from past
meanderings of the mind:
1. use generic data structures to keep track of general revision
histories for fields; would probably need something to support all of
the common different field types (could use a single less than 255
character string, maybe some other simplifications)
2. do something to track together sets of fields that are changed at
the same time, at least the fields in the same entity and perhaps
even those across an entire transaction
3. do something to track who made the change (harder since the entity
engine doesn't require user information to be passed down, and it's
not always available), and when the change is made (pretty easy, we
do it all the time already)
Once all of this is in place all you'd have to do is set some sort of
track-revisions="true" attribute on each field definition you want
tracked.
Is this something you are interested in developing, or sponsoring the
development of?
