hey all, I'm having some difficulty with freemarker in my email template sometimes no shipping cost is entered for an order, so when that happens I want to check if

${transaction.shippingcost}

is an empty string/null/whatever, but for some reason

<#if transaction.shippingcost?has_content>

always evaluates true, even when it spits out nothing when the template actually renders - I tried

transaction.shippingcost??

as well but it still evaluates to true
