Alex,
i used the following and it worked ok with struts2.
In JSP :-
<s:textfield name="opportunity.opportunityItem[0].quantity" value="12" size="5"
maxlength="5" theme="simple" cssClass="mandatory"
onblur="setListPrice(%{#rowstatus.index})"/>
In Action, i have a get/set for opportunity which is an object with the
following property (with get/setters)
private Collection opportunityItems = new ArrayList(0);
and the following additional method in the opportunity class
public OpportunityItem getOpportunityItem(int occ)
{
Collection coll = this.getOpportunityItems();
Object[] objs = coll.toArray();
OpportunityItem oppItem = null;
if (objs[occ] instanceof OpportunityItem)
{
oppItem = (OpportunityItem)objs[occ];
}
return oppItem;
}
you could cast the collection to ArrayList and use .get(occ) but i wanted to be
able to change collection type.
struts2 then takes "opportunity.opportunityItem[0].quantity" and does...
getOpportunity().getOpportunityItem(0).setQuantity(12)
i've found the utility methods are sometimes needed to handle arrays.
if it was just a repeating field you could define a String[] and have the
fields with the same name and struts would populate it for you.
regards
adam
