Struts (classic,vanilla,action whatever) does deal with this. You can add new items to a list backed form thats scoped to request, without losing existing items.. As the parameters are converted to attributes, and the action form is populated when a form is submitted when a struts action forwards back to the form, it remains populated.. Maybe I'll try playing with phaselisteners again and see if something similar will work with JSF. The datatable is populated in the first place, it must be possible some how to repopulate a datatable from the submitted values.
