Hi All,
We're still trying to track down the issue with one Editing Context
somehow getting itself permanently attached as the Databases Active
Editing Context. In fact we have an instance of it where it produces
this error :
Cannot obtain globalId for an object which is registered in an other
than the databaseContext's active editingContext, object: Researcher:
(Active_Name=Peter Newnam {rowID=28082;}, databaseContext:
com.webobjects.eoaccess.EODatabaseContext@2cd728, object's
editingContext:
edu.uow.ris.framework.LockErrorScreamerEditingContext@10c6406,
databaseContext's active editingContext:
edu.uow.ris.framework.LockErrorScreamerEditingContext@1efaa51
And then keept the session alive for 24 hours ( at which point we
restarted Tomcat) and was considered the active editing context for
that whole time, which meant that no one else could log into the
system, thankfully this was on our Test Server.
So Im going back to basics, just in case I missed something or my
understanding of these things is flawed :
1) What exactly is the Databases active editing context ?
2) How/When does a EC become the databases active editing context ?
3) How/When is it no longer considered the databases active editing
context ?
4) Should it be possible for an EC to be the active one across
multiple RR Loops ? And if so why ?
5) Is there only one databases active editing context for each
instance of the application or is it one per session ?
