OK, well, it looks like I'm out of luck here.
Can I ask: has anyone out there _successfully_ created a WO4/EOF3 app that:
-- has multiple eomodels
-- where each eomodel is for a different database
-- where entities in one eomodel have relationships to entities in another
model
-- where those entities are instantiated and their relationships
manipulated programmatically in the app (ie, not just fetched from the db)
-- and then succesfully inserted those back into the database(s)?
I received a report of one other site suffering from this problem (using
Obj-C not Java in this case), and a couple of sensible but unsuccessful
suggestions that didn't fix the problem.
Best wishes
Garrick

** Sorry for the cross-post. I posted this to the EOF list a
** few days ago but
** it seems that the WOF list is where all the action is these days.
**
** I believe this is a bug in the current release of WO4/EOF.
** I'd be most
** grateful if anyone can suggest a workaround. The problem
** appears to centre
** around a project having multiple eomodels which connect to different
** databases, and objects in those eomodels having
** relationships across models
** to each other.
**
** And please don't let the company standard email disclaimer

** Hello
**
** Well I'm opening myself up to a fresh torrent of spam in the
** hope that
** someone here can help me. I'd like to know if I'm doing
** something wrong here
** or am hitting a (dare I suggest it) bug in EOF3.0. The smart
** money's on me
** doing something wrong. I'd be grateful at least if anyone else who's
** encountered anything like this could give me some clues, a 'me too',
** workaround, anything...

**
** Environment:
** EOF3.0; Java; WOF4.0; NT4SP3; Sybase
**
** Possible factors:
** multi-eomodel project/app, including cross-model,
** cross-database relationships.
**
** Error encountered:
** "recordToManySnapshots:: cannot record objects in a
** context when no
** transaction is in progress"
**
** Scenario:
** I'm instantiating a couple of eocustomobject
** subclasses, inserting
** them into an editingcontext, relating them to some
** preexisting fetched
** eocustomobject subclasses in another model/database, and
** then saving the
** editing context. All objects (in all models) are in the same editing
** context. EOF is successfully preparing the objects, fetching
** primary keys,
** generating the correct 'INSERT INTO' SQL, submitting it to
** Sybase, but then
** just when everything appears to have completed, the whole
** lot gets rolled
** back with the EOF error message above.
**
** If I remove the 'addObjectToBothSidesOfRelationship' calls
** which relate the
** new instances to objects in other models/databases, the
** editingcontext.save() succeeds. But, of course, I need my
** objects to be
** related across the models...
