Intermittently, I am getting the following exception on a forum thread with replies:
System.NullReferenceException: Object reference not set to an instance of an object. at Telligent.Evolution.Forums.Internal.ForumService.GetThreadedRepliesForReply(Int32 threadId, ForumRepliesListThreadedForReplyOptions options) at Telligent.Evolution.Extensibility.Api.Version1.ForumReplies.ListThreadedForReply(Int32 threadId, ForumRepliesListThreadedForReplyOptions options)
Looking at the scripted-file.ashx request URL through the browser for the requested page (URL generated from callback-model-list-replies.vm in Forum-Thread), I don't see any parameters that are missing or different from a working request on the same forum. (Obviously the threadId and replyId are different as expected).
I suspect that the threads where this error is occurring had some, but not all, replies deleted in the past and perhaps that's what is causing the turmoil.
On the threads where this occurs, the reply count shows the correct number but the replies are never displayed due to this exception.
What's my best next step to track this down?
Additional potentially relevant information:
Version 12.0.1.15778
URL for reply is in new format (sitename/group-name/group-name/f/forum-name/#####(threadId)/thread-title/#####(replyId))
ui.js is default version (but reports many syntactical errors in Widget Studio relating to missing or errant semi-colons)
