Hi,

I am getting error "Object Reference not set to an instance of an object" while I am trying to use IRecordContext  to get current workspace record in an Add-in type "Analytics for External Data". I attached this report add-In in a sub tab  of contact workspace and I need to fetch some of the fields value at the time of workspace loading. 

here is my code 

class 1 ReportPackage Implementation

using System.AddIn;

using System.Collections.Generic;

using RightNow.AddIns.AddInViews;

using RightNow.AddIns.SampleReportTableAddIns.IVRDataNet;

using System;
 
using System.Collections.Generic;
 
using System.Data.Services.Client;
 
using System.Linq;
