FreeMarker template error (DEBUG mode; use RETHROW in production!): The following has evaluated to null or missing: ==> art.articleTag [in template "pages/xw.html" at line 133, column 60] ---- Tip: It's the step after the last dot that caused this error, not those before it. ---- Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing. (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: ${art.articleTag} [in template "pages/xw.html" at line 133, column 58] ---- Java stack trace (for programmers): ---- freemarker.core.InvalidReferenceException: [...
