[CLOSED] ListFilter System.InvalidCastException

[cwolcott]

I had a list filter that worked in v1.2 just fine, but I am receiving an error in v2.0. I will continue to research, but just wanted to check if there are any known errors.

 <Features>
      <ext:GridFilters runat="server">
         <Filters>
            <ext:ListFilter DataIndex="PerCatNm"   Options="Dog, Cat, Fish" />
         </Filters>
      </ext:GridFilters>
   </Features>

The filter displays just fine in the Grid column, but once I select one of the items I receive the error:

{serviceResponse:{success:false,message:"System.InvalidCastException: Cannot cast Newtonsoft.Json.Linq.JArray to Newtonsoft.Json.Linq.JToken.
at Newtonsoft.Json.Linq.Extensions.Convert[T,U](T Token) in d:\\development\\Releases\\Json\\Working\\Src\\Newtonsoft.Json\\Linq\Extensions.cs:line 261

When I traced through the code the issue seems to be at:

FilterConditions.cs - Line 65 An exception is raised here:

condition.Value= jObject.Value<string>("value");

The jObject is current

{ "type":"list", "value": [   "Dog",    "Cat"  ], "field":"PersCatNm"}

The Newtonsoft.Json.dll is Assembly Version 4.0.8.0, File Version 4.0.8.14612
