Just went live with an upgrade from 10.1 to 11.1.1.9982 and added some ideations to a group. The group banner was configured for "Group Ideation" even though there is only one ideation in the group but it didn't show the link in the group banner and the following exception seemed to be logged by all visitors in the group:
System.InvalidOperationException: Nullable object must have a value. at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource) at Telligent.Evolution.Ideation.InternalApi.Ideations.<>c.(Group ) at System.Linq.Enumerable.WhereSelectEnumerableIterator`2.MoveNext() at System.Linq.Buffer`1..ctor(IEnumerable`1 source) at System.Linq.Enumerable.ToArray[TSource](IEnumerable`1 source) at Telligent.Evolution.Ideation.InternalApi.Ideations.List(Int32 , ChallengesListOptions , Boolean ) at Telligent.Evolution.Extensibility.Ideation.Api.Challenges.List(Int32 groupId, ChallengesListOptions options)
I changed the group banner to specifically link to the single ideation and the exceptions seemed to have stopped around the same time. Just want a sanity check that I caught it in the right spot.
(Had some hiccups in the upgrade so a bit more nervous that usual)
