FreeMarker Error : left-hand operand: Expected a hash, but this evaluated to a sequence
When I loop through a list in freemarker like below, it works fine.
<#list cModel.products as product>
But when I'm tring to assign the size of the list to a variable like,
<#assign totalProducts = cModel.products.getList()?size>
I'm getting an exception from free marker like below
left-hand operand: Expected a hash, but this evaluated to a sequence
Any suggestions?
