ORMLite : Internal DAO object is null

Question

I\'m using ORMLite, trying to use the ForeignCollectionKey but I got the following error :

Internal DAO object is null. LazyCollections cannot be use

Answer 1

I solved this problem like Gray suggested: pass the primary key attribute in the Bundle and then obtain the object again from the database in the destination Activity:

Example:

Let's suppose I want to pass a Person object and that I've declared Person.name as:

@DatabaseField (columnName ="name")
private String name;

Then:

ActivityA

Intent intent = new Intent(ActivityA.this, ActivityB.class);
Bundle bundle = new Bundle();
bundle.putString("NAME" Person.getName());
intent.putExtras(bundle);

ActivityB

String name = getIntent().getExtras().getString("NAME"));
Person p = getHelper().getPersonDao().queryForEq("name", name);

And there you are, your Collection will be refreshed.
