Add several elements to a node

Question

Hello experts,
I'm trying to add several elements to a node I have, the node cardinality is 0..n and the data I'm trying to pass comes from a hashtable, this is the code I have:
ICifrasControlElement cifras = wdThis.wdGetContext().createCifrasControlElement();
for(;enum.hasMoreElements();){
String key = (String)enum.nextElement();
String value = (String)res.get(key);                    
cifras.setConcepto(key);
cifras.setValor(value);
wdContext.nodeCifrasControl().addElement(cifras);
I'm getting this exception:"cannot bind or add element, because it is already bound to a node"

Jesus-
Your problem is you have created only one element and you are adding the same reference in the loop. Change your code as follows:
for(;enum.hasMoreElements();){
String key = (String)enum.nextElement();
String value = (String)res.get(key);                    
ICifrasControlElement cifras = wdThis.wdGetContext().createCifrasControlElement();
cifras.setConcepto(key);
cifras.setValor(value);
wdContext.nodeCifrasControl().addElement(cifras);
