Chris,

Maps are serialized as 'name : value' pairs, whereas Lists are serialized 
as Arrays. Change your return type to a List and try.

Ajax Response - Array Objects



I cannot seem to get my Ajax request to return to the Ajax client an
array of objects.  Instead of simply returning a key/value pair, I've
read that it is possible to return the actual domain objects, but I have
been unsuccessful.   Each time, my combo box is populated with three
values, message type number. 

In the JSP I have:

sx:autocompleter 
 href=%{customersUrl} 
 preload=true 
 name=customer 
 valueNotifyTopics=/CustomerChanged 
 forceValidOption=true 
/

In the Struts configuration I have:

package name=ajaxpkg namespace=/ajax extends=json-default
  action name=ajaxCustomersList
class=com.examples.struts2.action.JsonAction
result type=jsonparam
name=rootcustomersList/param/result
  /action
/package

And finally in the Struts action I have:

public MapString,Object getCustomersList() 
{
  // Get the customer data from the service layer
  ListCustomer customers = customerService.getAllCustomers();

  // If no data was returned, return an empty collection
  // as the browser will display an empty list.
  if(customers == null)
return new LinkedHashMapString,Object();

  // Data was obviously returned, create new map and populate
  // the map with the customer ID as the key and the actual
  // customer object as the payload for each pair.
  MapString,Object json = new LinkedHashMapString,Object();
  for(Customer customer : customers) {
json.put(customer.getId().toString(), customer);
  }

  // Hand result back to Ajax client
  return(json);
} 

Can anyone explain what I have missed here in my implementation and/or
what needs to be corrected. 

Thanks,
Chris

RE: Ajax Response - Array Objects

2010-07-16 Thread CRANFORD, CHRIS 

Thanks for the suggestion, that worked.  

Now what I find odd is that when using the listKey/listValue parameters
for the autocompleter tag, it doesn't populate the dropdown when the
data is sourced from a remote URL.  If I request the Ajax service, I get
the serialized data as I would have expected, but for some reason the
widget isn't populating the dropdown with it now.  

Any suggestions?
