I would like to create a Table in XFA. I bind TextField in row to $.field.atr[*]. This is working fine. But I do not know how to set optional attribute "art". I was trying using: a) xfa.data.resolveNode("root.field.art").value b) xfa.data.resolveNode("root.field").setAttribute('art','value'); c) Instead of xfa.data I used xfa.data.datasets d) and something more But any of this does not work. What am I doing wrong? Thanks for any help.
