Retrieving an EO from a serialized Propertylist in database table textfield
I am trying to get a NSarray of NSDictionaries with Objects from one
application to another application via a database text field.
My idea was that I would first serialize the stuff on one side:
setPlistTextField ( NSPropertyListSerialization.stringFromPropertyList( cart()
) )
next, get it out on the other side:
itemsList= (NSArray) NSPropertyListSerialization.propertyListFromString(
plistTextField() )
And then from the NSDictionary retrieve the EO Objects with some EOUtilities
method.
I first thought that
Product ciProduct = (Product) EOUtilities.localInstanceOfObject(
session.myEc(), (nl.netsense.theater.Product)
tmpCartItem.objectForKey(product) )
would do the trick, but that is not the case (I can imagine that the stuff I am
sending it is not really a EnterpriseObject.
The NSDictionary that I am getting contains stuff like this:
{performance = nl.netsense.theater.Performance pk:994; total = 11.0;
qty = 1; product = nl.netsense.theater.Product pk:136; }
Which EOUtilities method would be able to retrieve the EO again from a
dictionary value like:
performance = nl.netsense.theater.Performance pk:994
?

Re: Retrieving an EO from a serialized Propertylist in database table textfield
Hello Johan;
You really need to serialise a GID and then deserialise the GID and fault it on
the target system. NSKeyGlobalID and NSTemporaryGlobalID both conform to
NSCoding so I guess that you could use that to achieve what you are after? You
could also use something like my JSON serialisation as an alternative.
cheers.

Antw: Retrieving an EO from a serialized Propertylist in database tabletextfield
Since the entity name and the primary key are known on the target side,
EOUtilities.faultWithPrimaryKeyValue(yourEditingContext, yourEntity,
yourPrimaryKey) will do the job.
PS (again): But since I can't get no sleep because of the olympic
games, I may have entirely missunderstood the actual crux. I apologize,
if this is the case -.-

Re: failed to provide new primary keys for entity
Hi, I'm still stuck :( I thought this information might be helpful. If I do a System.out on entity.primaryKeyAttributeNames() I see the right keys. If I System.out on the relationships I can see they are properly set and not null. Yet, if I System.out on entity.primaryKey I get a return of null. Could this be a bug in the MySQL plugin?
