I am trying to get generics to work using custom type handlers.  I have
it working with simple "known" types.  For example, adding a handler for
a Nullable(Of DateTime) would look something like this...

<typeHandler

type="System.Nullable`1[[System.DateTime]]"

     dbType="datetime"


callback="ATG.Database.TypeHandlers.NullableDateTimeTypeHandlerCallback ,
ATG.Database"/>


This works great.  If you have to further specify the generic type,
ibatis runs into problems.  For example

<typeHandler

     type="System.Nullable`1[[ATG.Money , ATG.Money]]"


callback="ATG.Database.TypeHandlers.NullableMoneyTypeHandlerCallback,
ATG.Database"/>

This fails inside the function SplitTypeAndAssemblyNames.  The function
simply splits on the ',' to find the dll to load.  If I change this
function to check if it is a generic type string it works fine.

     if (typeAssemblyIndex < 0 || originalTypeName.Contains("`1[["))

Is there an issue doing this?  If not can it be added to the core code?

Thanks
