signup forms isn't visible into a views2 instance

Hi everyone,

I tried to create a simple view, with a node type based display (no fields).

My node type is signup-enabled and I attend to see a signup form at the end of each node.

The single node display works well, so I see signup form correctly.

On the contrary, the same views-based visualization shows only nodes (title and body), without signup forms.

Many thanks for your help.
