Bookmark list displays exception when user id not exist #37

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.Choose an invalid user id (larger than last registered)
2.Visit http://www.andowson.com/bookmarks/list/<invalid_user_id>.page
3.For example, http://www.andowson.com/bookmarks/list/2949.page

What is the expected output? What do you see instead?
JForum should show an error message like "User not exist".

Instead, we see the error message in the jforum.log:
