(These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)?? ---- ---- FTL stack trace ("~" means nesting-related): - Failed at: ${news.createusername} [in template "content_op.html" at line 32, column 22] ---- Java stack trace (for programmers): ---- freemarker.core.InvalidReferenceException: [...
