Hello,
I am new to google app engine and i am having some trouble in saving
some data.
I have a class that have lists, those list have been 'declared'
persistent and i don't want any relation to be involved. However when
i try to save the object the data on the lists aren't saved. From what
i read of the documentation i should be able to save the lists without
any problem.
Here is the relevant code:
@Persistent
private List<Long> incomingFollowRequest;
public User(String name, String screenName, String adress, String
zipCode, String email)
{
this.name= name;
this.screenName= screenName;
this.adress= adress;
this.zipCode= zipCode;
this.email= email;
this.incomingFollowRequest= new ArrayList<Long>();
this.messageManager= new MessageManager();
this.following= new ArrayList<String>();
this.followedBy= new ArrayList<String>();
this.incomingFollowRequest.add(11l); // to see if the data is being
saved
}
user= new User("Test 2", "Bla2", "CCCCC2", "guess it 2",
"[email protected]");
CommonDbCommands.AddUser(user);
static public void AddUser(User user)
{
PersistenceManager pm = PMF.get().getPersistenceManager();
Transaction tx= pm.currentTransaction();
try
{
tx.begin();
pm.makePersistent(user);
tx.commit();
}
finally
{
if(tx.isActive())
{
tx.rollback();
}
pm.close();
}
}
