I don't have any ideas, but if you're new to iBatis, I assume you've checked the inner exception. iBatis often puts tidbits in there that are helpful if it's a configuration issue (which it doesn't look like at first glance).
-----Original Message----- From: Chick, Brian [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 15, 2007 3:42 PM To: [email protected] Subject: GroupBy & Constructors I'm trying to use the groupBy attribute in conjunction with a constructor. When using the groupBy attribute with the default no-args constructor, it works great. Having issues using it when specifing a constructor. My resultmap that looks like this: <resultMap id="ResultId" class="ResultClass" groupBy="TheUniqueId"> <constructor> <argument argumentName="inUniqueId" column="ID" dbType="Integer"/> <argument argumentName="inValOne" column="VAL_ONE" dbType="string"/> <argument argumentName="inValTwo" column="VAL_TWO" dbType="string"/> </constructor> <result property="TheUniqueId" column ="ID" dbType ="Integer"/> <result property ="ChildObject" resultMapping="Domain.DataAccess.SqlMaps.ChildMapping"/> </resultMap> Throws the following NullReferenceException: System.NullReferenceException was unhandled by user code Message="Object reference not set to an instance of an object."
