FreeMarker template error (DEBUG mode; use RETHROW in production!):
The following has evaluated to null or missing:
==> info['labelName_'+labelIndexs] [in template "1/default/plug/front/version1/gaoxiao_class_new.html" at line 373, column 85]
----
Tip: It's the final [] step 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)??
