Hi, I had a similar requirement for a form here. I had an List of object to visually edit. The objects were carrying their description, value and type. I created, for each type, a wrapper bean that provided a method UIComponent createEditor(some environment stuff); I then created a custom component (let's name <custom:genericEditor value="<wrapped object to edit>"), that has responsability to 1) setup, for it's children, an accessible request scoped variable that refered to objet to edit 2) create a tomahawk subform (some very complex editors needed to do partial submit) 3) act as NamingContainer 4) dynamically populate the subform's children list upon first need using the createEditor()
