Returning unsaved records in an ObjectContext with SelectQuery

[John Huss <jo...@gmail.com>]

Is there a way to have a SelectQuery also return matches found in the
unsaved objects in the ObjectContext?  If not, how can I query the contents
of the ObjectContext to look for matches?

In WebObjects / Wonder, there was a property you could set on the context -
setIncludeEditingContextChanges(true) that would do this.

Thanks,
John

We've done something similar in specific cases by subclassing 
ObjectContact and searching through the context. I agree that it would 
be nice to have a switch for this which basically enables 
http://cayenne.apache.org/doc/in-memory-evaluation.html to be added to 
the results from the database.

I've accomplished what I needed with some custom code for now.  So ignore
this.
