I'm using ormlite-core-4.46 and ormlite-android-4.46, and I'm still getting this error. below is my exception trace log:

and this is the class which has the foreign collection:

@DatabaseTable(tableName = "activity")
public class CardActivity {

    @DatabaseField(generatedId = true)
    private int _id;

    @DatabaseField
    private String name;

    @DatabaseField
    private Date start;

    @DatabaseField
    private Date end;

    @ForeignCollectionField(eager = false)
    private ForeignCollection<Relation_Participants> participants;

this is the class which has the foreign field to the above class:

@DatabaseTable(tableName = "relation_participants")
public class Relation_Participants {
    @DatabaseField(generatedId = true)
    private int _id;

    @DatabaseField(foreign = true)
    private CardActivity activity;

    @DatabaseField(foreign = true)
    private Player player;

Anybody knows that the problem is??? It's really driving me crazy!!

I assume the android config.txt as the ormlite_config.txt, So I delete the file, and generate the file again, but the problem still persists. Below is the file:

java.lang.IllegalArgumentException: Field FieldType:name=activity,
    class=Relation_Participants is a primitive class
    class com.lordcardrecorder.model.CardActivity but marked as foreign

So for some reason ORMLite thinks that your Relation_Participants class is a primitive type. I suspect that the problem is invalid information inside of your Android ormlite_config.txt file which caches the field and type information. I would immediately remove this file and then re-run your program to see if it works. If it doesn't then you need to regenerate it.

If the problem still happens then please post the section of the ormlite_config.txt file that lists the Relation_Participants fieldd. Is it saying it is a primitive?
