async access to DaoManager

[Shawn Hinsey <Sh...@miva.com>]

Hello,

I have the following base class that all of my domain objects use to
grab references to the appropriate DAO. 

A couple of common usages:

BookCollection myBooks = Book.Load();

Book myBook = new Book();
myBook.Title = "A Tale of Two Cities";
myBook.Save();

	public class DomainBase
	{
		static DomainBase()
		{
			_builder = new DomDaoManagerBuilder();
			_builder.Configure();
			_manager = DaoManager.GetInstance("SqlMapDao");
		}

		protected static DaoManager _manager;

		protected static DomDaoManagerBuilder _builder;

		public static T GetDao<T>()
		{
			try
			{
				return (T)_manager.GetDao(typeof(T));
			}
			catch (Exception ex)
			{
				throw ex;
			}
		}
	}

The problem I'm running into is that when I invoke GetDao from an
AsyncCallback delegate, I run into this exception:

 IBatisNet.DataAccess.Exceptions.DataAccessException: There is already a
DAO Context with the ID 'SqlMapDao'.

What am I missing in order to make this thread-safe?
