Exception in DaoProxy (.Net). Any help is appreciated

[Chtelmakh, Oleg]

Hello,

I would appreciate any help in resolving the following issue.

We are evaluating IBatis DataAccess 1.8 and DataMapper 1.5. (binary distributions).

When executing the following test:

[Test]

public void GetAllCountriesViaDao() {

ICountryDao dao = GetCountryDao();

Assert.IsNotNull(dao, "Dao not created ");

IList cl = dao.GetCountryList();

Assert.IsNotNull(cl, "Counties not retrieved is Null");

Assert.IsTrue(cl.Count > 0 ,"Empty Country list");

}

Where

GetCountryDao() looks like:

..

private ICountryDao GetCountryDao(){

..

return daoManager[typeof(ICountryDao)] as ICountryDao;

..

And CountrySqlMapDao class looks like:

...

[Serializable]

public class CountrySqlMapDao: BaseSqlMapDao, ICountryDao {

public CountrySqlMapDao(): base() {

}

public virtual IList GetCountryList(){

return ExecuteQueryForList("SelectAll", null);

}

....

 

I am getting the following exception:

DAOTester.CountryDaoTest.GetAllCountriesViaDao : IBatisNet.DataAccess.Exceptions.DataAccessException : DaoProxy : unable to intercept method name 'GetCountryList', cause : Invalid argument

----> System.ArgumentException : Invalid argument

Oleg
