Icefaces - ace:datatable with more than 1 value

Question

I would like to have an ace:datatable where I can compare an "old" object against a "new" object. Unfortunately I can only use List of Object to handle only one Object per row. Is it possible to handle more than one object per row?

If both lists will have always the same size you could try something like this.

                    <ace:dataTable value="#{bean.oldList}" var="item" rowIndexVar="index">
                    <ace:column headerText="Old Value">
                        <h:outputText value="#{item.value}"/>
                    </ace:column>
                    <ace:column headerText="New Value">                            
                            <h:outputText value="#{bean.newList[index].value}"/>                              
                    </ace:column>                  
                </ace:dataTable>

However i don't really like this because it can lead to index out of bound exception Perhaps you could also try playing with nested datatables.
