Louis,
Trying to save a single EO while leaving others unsaved is almost
always indicative of a problem in your application's design. Think of
an EOEditingContext as being somewhat like an SQL transaction, except
that it persists in RAM beyond a single commit. Now, saying that you
need to save a single EO is like saying (in the context of an SQL
transaction) that you want to commit just one of several UPDATEs that
are a part of the transaction; you're working against the grain of
the frameworks. You should probably go back and re-think your design,
so that you are no longer trying to save the single EO -- instead,
your natural flow will be to save the entire state of the object
graph tracked by the EC.

Hi
I would like to save newly created EO immediately but there could be
other objects in the default EditingContext which I do not want to
commit to the database immediately.
My first attempt was to create a new short term EditignContext,
insert my newly created EO in it and call saveChanges.
However because this object has a relationsip to another one in the
defaultEditingContext, it cause an error about being unable to obtain
globalId
Any suggestions how to acheive this ?
