FreeMarker template error (HTML_DEBUG mode; use RETHROW in production!)
The following has evaluated to null or missing:
==> valSet.ppv_price [in template "WEB-INF/template/shop/product.ftl" at line 542, column 130]
----
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)??
