Mark - I understand where you are coming from, and did try your
suggestion. But I still am NOT getting a user EO instance (I get null
per the debugger).
Actually I checked the WO docs and both valueForKeyPath AND valueForKey
are valid methods of the Session class. Problem is what is the correct
syntax. The docs say object.valueForKey(string), and your suggestion
provided the object part (ie session()) (I also tried your input +
valueForKeyPath but Eclipse complained about 'no such key = session')
So I still am at a loss on how to retrieve a user EO from the session. :-(
But thanks for your help/input!

Hello,
I have a basic question on how to access the logged in user for later
use in updates. After authenticating a user I enter him into the
session, but when I later try to retrieve this user in another page,
it fails(returns null).
So in my main page I record the user as follows:
if (_password.equals(password)) { EOEnterpriseObject user
=
EOUtilities.objectMatchingKeyAndValue(session().defaultEditingContext(),
"User", "name", username);
// set the session.user
session().takeValueForKey(user, "user");
And on another page to add a new transaction which needs the user
relation attribute(as a foreign key):
EOEnterpriseObject user = (EOEnterpriseObject)
valueForKeyPath("session.user"); // user evals to null???
Try changing this to:
EOEnterpriseObject user =
(EOEnterpriseObject)session().valueForKey("user");
valueForKeyPath is useful, but I don't think it can do what you're
asking of it here.
purchase.addObjectToBothSidesOfRelationshipWithKey(user, "user");
The save fails because user is a required attribute. And I'm not sure
if I am not properly storing the user in the session, or not properly
retrieving the user from the session.
Can anyone see what I am doing wrong or suggest another approach?
TIA
Personally, I usually make currentUser an actual variable in Session.
(Private, with public accessor methods, of course! ;-)
Regards,
Mark
