Lot of thanks Leigh for your clear explanation. Between this options, I prefer to model the state of the form in the instance data, and with the post-submission event "xforms-submit-done". I think it would be better with the ev:event="xforms-submit" you propose but I should listen to xforms-submit-error in this case, as you say, and I don't want to arrive to this level of complexity yet.
