无法插入级联数据

@Table("tb_user")
public class UserModel extends BaseModel {
private static final long serialVersionUID = 1L;

public static final String COL_MOBILE = "mobile";

@NotNull
@Column(COL_MOBILE)
private String mobile;

@Mapping(Relation.OneToMany)
private ArrayList roles;
}

@Table("tb_role")
public class RoleModel extends BaseModel {

@Unique
@NotNull
private int roleId;

private String role;

}
用
public void insert(T t) {
getLiteOrm().cascade().insert(t, ConflictAlgorithm.Abort);
}
插入数据userMode,UserModel中其他字段都可以插入，唯独roles是空

Start at the public insert(T t) entry point and trace getLiteOrm().cascade().insert with the UserModel.roles mapping. Compare how UserModel and RoleModel are processed, then verify that the roles data is persisted along with the user and that the existing non-role fields still insert correctly.
