FreeMarker template error!
FreeMarker template error: The following has evaluated to null or missing: ==> event.dt_surrogate_key [in template "ComponentTemplateSource:Featured Event:503140" at line 5, column 15] ---- 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[/#if]. (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: #assign id = event.dt_surrogate_key [in template "ComponentTemplateSource:Featured Event:503140" at line 5, column 1] ---- Java stack trace (for programmers): ---- freemarker.core.InvalidReferenceException: [...
