OTM and Report Queries
Are we supposed to be able to do report queries from the OTM?

hi brian,
this would imply that we know the identity of the retrieved objects which is not
the case in the current implementation. an even bigger issue would be to modify
joined results.

I know, was thinking about possibility of doing it as projection from
live objects =) If it would even be worth the effort is another matter.

hi brian,
report queries are a imo read-only thing.
the result of a report-query is a collection of object-arrays not real
business-objects.

Re: OTM and Report Queries

I am all for supporting it, but make sure the semantics around it are
clear -- are these transactional bound reports, can you manipulate
values and have them reflected back into objects (actually, that would
be interesting, report query as projection of object model); or is it
simply a snapshot report?

I still think that the method for creating report queries via OTM interface
may be convenient. Can anybody say "Yes" to this? :))))

I don't personally care about the ability to do it, just trying to push
around the edges to see what is in and our of the OTM's scope. If
reports are outside scope, that is fine by me =) Just confirming that
it is on purpose.

I didn't see much sense in this: what object transaction things should OTM do
for report queries?
I will add such method to API if you think this would be convinient.
