java.lang.RuntimeException: no terms in field post.id - cannot determine sort type

Hi guys,
I have JForum 2.1.8 and when I try to search something and I do not use the "relevance" sorting option but "message date" I get the following error

Have anyone had thi problem? I have a fix for this but I am not sure if the solution is correct - in class LuceneSearch.java in line 174 I specified the sort type

sort = new Sort(new SortField("post.id", SortField.STRING, "DESC".equals(args.getOrderDir())));

and it works, but I think there must be better solution, I am not completely sure what's going on here - maybe some improper indexing approach, or other problem related to improper database structure or setting?

Thanks.

Ok,
I think I have found a clue - the problem is that the lucene index file is not probably generated - maybe it can be caused by the fact that I deploy jforum.war file a couple of times in a day. And if the information whether the index file is generated or not is stored in the jforum database it could cause the problem. But I would expect that the mechanism is smarter - is anybody able to tell me how this works?

Thanks.
