Hi,

I'm trying to write a TopicQuery that returns hot topics by using the IsHot property, see code below:

TopicQuery topicQuery = new TopicQuery();
topicQuery.IsHot = new BooleanCriterion();
topicQuery.IsHot.Value = true;
topicQuery.CreateDate = new DateTimeCriterion();
topicQuery.OrderBy.Add(new CriterionSortOrder(topicQuery.CreateDate, EPiServer.Common.Sorting.SortingDirection.Descending));

int totalItems;
MessageCollection topics = QueryHandler.GetQueryResult(topicQuery, Utils.CacheTimeOut.MostRecent, 1, 5, out totalItems);

lvHotDiscussions.DataSource = topics;
lvHotDiscussions.DataBind();

The code compiles, but when I try to view the page I get the following error:

NHibernate.QueryException: could not resolve property: IsHot of: EPiServer.Community.Forum.Topic 
[SELECT EPiServerCommunityForumTopic FROM EPiServer.Community.Forum.Topic AS EPiServerCommunityForumTopic 
INNER JOIN EPiServerCommunityForumTopic.Room WHERE (EPiServerCommunityForumTopic.Room.Removed = 0) 
AND (EPiServerCommunityForumTopic.IsHot = :p0) ORDER BY EPiServerCommunityForumTopic.CreateDate DESC ]

There seems to be a problem with the IsHot property. Am I using it correctly or 
does it need to be configured?

Regards,
Helena
