Hello guys,
I am using Java. Usually when I am storing data, it will be a number
of objects at the same time.
I will first create many objects and then use
persistenceManager.makePersistentAll(Objects);
persistenceManager.close();
My system sometimes, will need to edit a few of these Objects, and I
do
Object.setAttribute(something)
persistenceManager.close();
I do not think there are errors sending in the data? I can view the
data in my datastore, just that when I click on it to fetch it(the
data entry's primary key has a blue link when you click on it you get
to edit the entry), it fails. When my app retrieves it through
persistenceManager.newQuery(sQuery).execute();, it works but when I
try to output the results of the query, it fails. Logs are clean. Is
my datastore input method wrong or something?
Thank you.
