Hi All,

I have a class "some_class" with attribute "begin_date" of type date.
In template i want to fetch instances of SomeClass where "begin_date" >= today date, so i
wrote:

{let items = fetch(content, 
                   list,
                   hash(parent_node_id, 64,
                        attribute_filter, array(
                                                array(some_class/begin_date, 
                                                      '>='
                                                      currentdate())))}

But it dosen't work right :(
