The following has evaluated to null or missing:
==> ws.app.catalog.getEvent(this.param("id")?number) [in template "web/page_event.ftl" at line 6, column 18]
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)??
