sam,
I hope we cannot use has_content with not existing variables. So, I suggest
to use 'exists' before has_content
#if productContentWrapper.get("DESCRIPTION")?exists?has_content>
${productContentWrapper.get("DESCRIPTION")}
<#else>
${productContentWrapper.get("LONG_DESCRIPTION")}
> </#if>
best wishes
