The form includes a select that when being changed triggers an ajax call and this inserts a new input field inside the form. Should it work that I get a value from the input field when the form is being submitted?

Does the input's id or name conflict with anything else in the page/form? Can you see in Firebug if the parameter is sent back to Seaside?  Why not just show/hide the textInput?  Are you submitting the form with ajax or in the traditional way?
Paul,

it is a text input field . It has name property and it is transferred to the server. I cannot see anything the input field conflicts with. I don't use toggle because I don't know upfront what has to be inserted. The select field selects a class that is transferred to the server. There a new instance is created and it is returned as magritte component. So I need the extra roundtrip.
