I have a partial class for entity ProjectScenario

ProjectScenario.cs

{

[Bindable(true, BindingDirection.OneWay)]

[DataMember]

public IEnumerable Pogs

{

get { return _pogs; }

set

{

_pogs = value;

if (_pogs != null && _pogs.Count() > 0)

CalcMetrics();

}

var qry = _pogs.GroupBy(p => 1)

.Select(p => new

{

Sales = p.Sum(x => x.Sales_ST_Wk_CUR),

Units = p.Sum(x => x.Units_ST_WK_CUR),

AGM = p.Sum(x => x.AGM_ST_WK_CUR),

GM = p.Sum(x => x.GM_ST_WK_CUR),

CM = p.Sum(x => x.CM_ST_WK_CUR),

VPE = p.Sum(x => x.VPE_CUR),

Loy = p.Sum(x => x.LOYAL_ST_WK_CUR),

SFF = p.Sum(x => x.SFF_CUR),

LFF = p.Sum(x => x.LFF),

SkuCount = p.Sum(x => x.SKU_Count_CUR)

});

var totals = qry.First();

if (RoundOffNullableValues(LOYAL_ST_WK_CUR) != RoundOffNullableValues(totals.Loy))

LOYAL_ST_WK_CUR = totals.Loy;

}

LOYAL_ST_WK_CUR is one of the predefined properties of entity ProjectScenario.

Code breaks on line that's highlighted in red...inside the ideablade code(the designer.cs file for the project inside ProjectScenario entity.):

atIdeaBlade.EntityModel.EntityAspect.SetValueWithChangeNotification(DataEntityPropertyproperty, Object newValue)

atIdeaBlade.EntityModel.EntityAspect.IdeaBlade.EntityModel.IStructuralObject.SetValueWithChangeNotification(DataEntityPropertyproperty, Object newValue)

atIdeaBlade.EntityModel.DataEntityProperty`2.SetValueWithVerification(TInstanceinstance, TValue newValue)

atIdeaBlade.EntityModel.DataEntityProperty`2.<.ctor>b__4(DataEntityPropertySetInterceptorArgs`2args)

atIdeaBlade.Core.PropertyInterceptor`3.ExecuteActions(TArgs args)

atIdeaBlade.Core.PropertyInterceptor`3.SetValue(TInstance instance, Objectcontext, TValue value)

atIdeaBlade.Core.PropertyInterceptor`3.SetValue(TInstance instance, TValue value)

atIdeaBlade.EntityModel.DataEntityProperty`2.SetValue(TInstance instance, TValuevalue)

atPerformanceOptimizer.ProjectScenario.set_LOYAL_ST_WK_CUR(Nullable`1 value) inC:\SPO\ForDeployment\DomainModel.win\SPOdb.IB.Designer.cs:line 14810

It throws a NullReferenceException on the above line.

Please suggest what can be the possible reasons and how do i fix this??
