Hi.I need to add a command in the Version function menu.For a 'normal' node, it is quiet simple : I just need to orphan WebNodeAction and set the node types in the _NodeTypes() feature. But this only works with node that have an entry in the dtree table, right?How can I link a WebNodeAction with a version, which doesn't seem to have any type?
