Hey Folks,
me again and already 2 things I have to clear up:
(1)
We're savin some kind of notes in our system which can be assigned only to
one person or to a list of persons.
Herefore we've got one table for the notes and a mapping table which saves
the noteid and the id of the person.
Alright, so I creata note and add a person as a recipient. Now I re-open the
window, remove the person i originally added to the note and add a new
person to the note. I hit the save button and everything works fine.
When I try to re-open the note cayenne gives me a nice exception:
19:19:52.204 WARN!! Exception for /ams?serviceId=Echo.Synchronize

Well, this exception comes on an object with the PersistenceState =
Transient. The exception is thrown when in doResolveFault cayenne tries to
access the object's context.
But why? This object shouldn't even be there! In my opinion this is a bug.
It doesn't matter, if we delete the object with deletObject or with a delet
query. How can it be? It's pretty severe though.
(2)
I try to access a mapping table again, this time we manage resources like
rooms, beamers etc.
I get all mappings and try to access via mapping.getToResource().getname()
the resource's name.
We get:
19:22:49.168 WARN!! Exception for /ams?serviceId=Echo.Synchronize
org.apache.cayenne.FaultFailureException: [EMAIL PROTECTED]@
@[EMAIL PROTECTED] Error resolving fault for ObjectId:
<ObjectId:Resource, IDRESOURCE=1> and state (hollow). Possible cause -
matching row is missing from the database.

message.
the data are there, at 100% all data and all constraints in the database are
there. I double-checked everything.
Please, could someone help me?
thanks in advance!
Jan
