You will get three xsds when you add a data connection. GetUserCollectionFromGroup, GetUserCollectionFromGroup1, GetUserCollectionFromGroup2. Open the GetUserCollectionFromGroup xsd and search for query fields. Replace that element with the following.
<xsd:element name="queryFields">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="GetUserCollectionFromGroup">
<xsd:complexType>
<xsd:sequence>
<xsd:element minOccurs="0" maxOccurs="1" name="groupName" type="xsd:string"></xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
Now open the GetUserCollectionFromGroup1 and search for ‘GetUserCollectionFromGroup' and replace that element with the following.
<s:element name="GetUserCollectionFromGroup">
<s:complexType>
<s:sequence>
<s:element name="Users" minOccurs="0" maxOccurs="1">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="unbounded" name="User">
<s:complexType>
<s:attribute name="Notes" type="s:string"></s:attribute>
<s:attribute name="Name" type="s:string"></s:attribute>
<s:attribute name="IsSiteAdmin" type="s:string"></s:attribute>
<s:attribute name="Sid" type="s:string"></s:attribute>
<s:attribute name="ID" type="s:string"></s:attribute>
<s:attribute name="LoginName" type="s:string"></s:attribute>
<s:attribute name="Email" type="s:string"></s:attribute>
<s:attribute name="IsDomainGroup" type="s:string"></s:attribute>
</s:complexType>
</s:element>
</s:sequence>
</s:complexType>
</s:element>
</s:sequence>
</s:complexType>
</s:element>
