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
11ca5
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.
