I believe the latest one 1.6.1 has = support for generic list. 

 

One thing I found is that it does n= ot work for all generic definitions, similar to Tony.

 

Example:

 

// In this example, I'm using Gener= ic to write less code.  Say Order's Child can access Order similar to = how Asp.NET Page.Controls[0].Page etc=85

 

OrderChild

&n= bsp;   /// <= font color=3D"gray"> <summary>

&n= bsp;   /// Simplify Order = Children class definition.

&n= bsp;   /// <= font color=3D"gray"> </summary>

&n= bsp;   [Se= rializable]

&n= bsp;   public class OrderChild : BusinessBase

&n= bsp;   {

&n= bsp;       /// <summary>

&n= bsp;       /// Order

&n= bsp;       /// </summary>

&n= bsp;       protected Order _order =3D=20 new Order();

&n= bsp;

&n= bsp;       /// <summary>

&n= bsp;       /// Get or sets Order

&n= bsp;       /// </summary>

&n= bsp;       public Order Order

&n= bsp;       {

&n= bsp;           get { return _order; }

&n= bsp;           set {

&n= bsp;            = ;   _order =3D value

&n= bsp;           }

&n= bsp;       }

&n= bsp;   }

//= Then I can do something= like this

public class = OrderLoanInfo : OrderChild { =85 }

public class = OrderDeliveryAddress : OrderChild { =85 }

//= This confuse the DataMa= pper and it doesn't know what to do if say I do #_orderLoanInfo.Order.LoanN= umber#

&n= bsp;

I = have to manually define the order object in every child class.

Hi,

 =

I'm struggling with = trying to get a custom generic list collection working with IBATIS lazy loa= ding. Basically, if I have a simple object with a simple mapping file that = lazy loads a list and that list is defined in my object as a List<T> = then things work fine. Eg:

 =

class myobject

{

=85

public List<subobject> Children{get=85 set=85}

}

 =

But as soon as I int= roduce a new class to take over the list, eg:

 =

public class MyList<T> : List<T>

{

}

 =

And then change myob= ject to use that:

class myobject

{

=85

public MyList<subobject> Children{get=85 set=85}=

}

 =

IBATIS no longer laz= y loads any data. I'm under the impression that any collection that impleme= nts IList or IList<T> will work transparently with lazy loading, yet = the MyList<T> class above implements these (albeit in the base class)= and it doesn't work.=20

 =

Am I doing something= stupid here?
