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?

I Hope you've accessing it wrongly.

As per your example, the list name is product. So,

<#assign totalProducts = cModel.getProducts()?size>

Should return back the size of the products.

Hope it helps.

cModel.products?size is the nicer way of doing that. – ddekany Jul 27 '14 at 13:57
