Naftoli, I like the checkboxes style for a small selection (say 10 or less), and perhaps a multi-selectbox if the choices are more numerous. Another approach is to use two list boxes, one for the choices and another for the selections, with maybe a drag-and-drop capability or some add/remove buttons in between. I guess there is no good default solution.
One enhancement to your tableeditor would be a tableviewer option, using a <field:toXml> instead of a <field:form> tag. Thanks for your help. Glenn...
