    I'm getting the error below when trying to view form responses on a particular form. What would be a likely place to start looking for the cause? This is not happening on all forms but just on this one.

    Exception information:
        Exception type: NullReferenceException
        Exception message: Object reference not set to an instance of an object.
       at Telerik.Sitefinity.Web.UI.ContentUI.Views.Backend.MasterDetailView.<GetScriptDescriptors>d__0.MoveNext()
       at System.Collections.Generic.List`1..ctor(IEnumerable`1 collection)
       at Telerik.Sitefinity.Modules.Forms.Web.UI.FormsMasterDetailView.GetScriptDescriptors()
       at System.Web.UI.ScriptControlManager.RegisterScriptDescriptors(IScriptControl scriptControl)

    Hi Ryan,

     We need additional information to determine the root of the problem. Would you open a support ticket and send us your project so we can set it up on our side and take a look, then we would be able to give you some ideas on what might be causing this issue.

    Regards,
    Miroslava

    Has this been resolved?  I'm getting this error as well.

    EDIT: Nevermind, my error was due to one of my own fields.  A custom form field that had an error in it.

    Thanks.
