Resolution: Fixed
in SVN
> Missing datatype can throw null pointer exception
> -------------------------------------------------
>
> Key: IBATISNET-163
> URL: http://issues.apache.org/jira/browse/IBATISNET-163
> Project: iBatis for .NET
> Type: Bug
> Components: DataMapper
> Versions: DataMapper 1.5
> Reporter: Ted Husted
> Fix For: DataMapper 1.5
>
> When using a numeric type that does not match a registred type, it's possible
> for the * to remain null. Then, at ResultProperty line 398 (build #412814, et
> seq.), the _typeHandler can be called directly
> * value = _typeHandler.GetValueByIndex(this, dataReader);
> This causes a deep null pointer exception that is difficult to trace.
> We should patch this with a null guard that throws an exception with a
> meaningful message, like "Handler for DataType not registered." Something to
> considerr would be to attach the exception message to the TypeHandler
> property., and then use the property rather than the private field.
