Description Jaroslav Tulach 2016-04-19 18:20:01 UTC 
Common error of people using @JavaScriptBody is that they return "undefined" instead of "null". The representation of undefined then differs in various presenters. Sometimes it yields class cast exceptions, sometimes unknown symbols. Better to avoid it altogether.
