Ruth Hoffman commented on OFBIZ-2865:
-------------------------------------
Note: this is a bug because when you enter the content information for a
digital product, contentName is not a required field.
Fix is to add ?if_exists as shown below:
<div
class="tabletext">${downloadProductContentAndInfo.contentName?if_exists}<#if
downloadProductContentAndInfo.description?has_content> -
${downloadProductContentAndInfo.description}</#if></div>
> productdetail.ftl returns a Freemarker error for digital download products
> when no contentName exists
