Nested OpenConnection() BeginTransaction()

[David Marzo \(Puzzlet\)]

I Have this scenarios that works ok:

        daoManager.BeginTransaction();
        daoManager.CommitTransaction();

        daoManager.BeginTransaction();
        daoManager.RollBackTransaction();

        daoManager.OpenConnection();
        daoManager.CloseConnection();

But this fail

 1) daoManager.OpenConnection();
 2) daoManager.BeginTransaction();
 3) daoManager.CommitTransaction(false);
 4) daoManager.CloseConnection();

With this Exception 

IBatisNet.DataAccess.Exceptions.DataAccessException : DaoManager could
not invoke BeginTransaction(). A DaoSession is already started. Call
CommitTransaction() or RollbackTransaction first.

In line 2

I check the source code and I found in IBatisNet.DataMapper.SqlMapper

/// <summary>
/// Begins a database transaction.
/// </summary>
public IDalSession BeginTransaction() 
{
        if (_sessionHolder.LocalSession != null) 
        {
         throw new DataMapperException(
        "SqlMap could not invoke BeginTransaction(). A Transaction is 
         already started. Call CommitTransaction() or
RollbackTransaction 
          first.");
        }
//...///

Is a bug, test for session instead for open transaction, or I missing
some piece of the puzzle.

In ADO.NET this scenario works

IdbConnection connection = <new connection>;
connection.Open()
IdbCommand cmdA = connection.CreateCommand();
<execute cmdA>
IdbTransaction transaction = connection.BeginConnection();
IdbCommand cmdB = transaction.Connection.CreateCommand();
<execute cmdB>
transaction.Commint()
connection.Close();


Thanks in advance

Un saludo:
