Hi all,
just wanting to clarify the do's/don'ts...
I'm getting "Cannot obtain globalId for an object which is registered
in an other than the databaseContext's active editingContext..."
Okay, my understanding is that you ought _not_ have relationships
going from a shared entity to a non-shared entity. Fine, so when the
application starts up I've got some code that removes any such
relations from the entities as they are registered (but leaving
intact the relations from the non-shared to the shared). This allows
me to specify an array property of "SharedEntities" relevant to that
application.
Now according to the api, I can create a regular editing context,
fetch the object into it, change it and save and that'll be all there
is to it. Nice theory.
I'm actually not needing to change that object but am setting the
relationship from a non-shared entity to the shared one. However the
exception I'm an exception that's preventing me from saving the context.
// Okay so I'm creating a editing context for editing like so:
public MyEditingContext editingContext() {
if ( _wec == null ) {
_wec = new MyEditingContext( clientForRequest( context().request() );
_wec.setSharedEditingContext( null );
_wec.setStopsValidationAfterFirstError( false );
}
}
// and in the awakeFromInsertion(EOEditingContext) I'm doing the
following:
{
if has reverse relation
// Note: this is where it's useful Mike :-)
addObjectToBothSidesOfRelationshipWithKey( aClient, key );
else
takeValueForKey( aClient, key );
}
Any ideas? What have I missed?
Thanks muchly...
with regards,
