FreeMarker template error (DEBUG mode; use RETHROW in production!):
The following has evaluated to null or missing:
==> tuple.selected[0] [in template "WEB-INF/views/default/frontend/common2/FilterUtils2.ftl" at line 782, column 55]
----
Tip: It's the final [] step that caused this error, not those before it.
----
Tip: If the failing expression is known to be 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)??
