Genexus: Use of Collection Variable in For Each

Question

I'm getting an error when I'm using a variable collection inside a For Each command:

For each
   where itemId in &items
   ...
   ...
   ...
EndFor

Where &items is a collection variable of Attribute itemId

How can I make it work?

Thanks in advance.

Pablo, What error are you having?

I suspect that ItemId (based on its name) is not at itesm.item type and should be that type. &Items collection of item &Item is defined as &items.item

for &Item in &items()
    &Item.Id
endfor
