[flexcoders] Re: Newbie, RemoteObject with ActionScript

Todd,
Sorry, I think I'm misunderstanding something very basic here. Aren't
both mxml and RO calling the method views.getView(test,
['nid','title','body','changed'])?

The method server side is views.getView(view name (string), fields
(array), args (array)). I've attached the code below.

Thanks for your help,
Ben


function views_service_service() {
  return array(
array(
  '#method'   = 'views.getView',
  '#callback' = 'views_service_get_view',
  '#args' = array('string', 'array', 'array'),
  '#args' = array(
array(
  '#name' = 'view_name',
  '#type' = 'string',
  '#description'  = t('View name.')),
array(
  '#name' = 'fields',
  '#type' = 'array',
  '#optional' = TRUE, 
  '#description'  = t('A list of fields to return.')),
array(
  '#name' = 'args',
  '#type' = 'array',
  '#optional' = TRUE,
  '#description'  = t('An array of arguments to pass to the
view.'))),
  '#return'   = 'array',
  '#help' = t('Retrieves a view defined in views.module.')),
  );
}

 The getNodes() call does not matter.  What matter is the RemoteObject
 method call.  It appears to me that you are passing different
 parameters in the AS implementation as you are the MXML implementation.
 
 I'll look again, but quite often I send the wrong types of parameters
 through an RO and the server side cannot find the method properly.
 
 With PHP, not really sure how an interface or method looks.

I am a relative newbie myself but don't you need a views.source =

Re: [flexcoders] Re: Newbie, RemoteObject with ActionScript

[Aaron Miller]

I'm not an expert on RemoteObject myself, but I do notice your code looks a
bit different then mine (which works).

Here is an example of a function that uses remote object in my project:

# public function loadFavorites( resultHandler:Function,
errorHandler:Function ): void {
#   var dataService:RemoteObject = new RemoteObject();
#
#   dataService.destination = amfphp;
#   dataService.source = FavoritesProxy;
#   dataService.loadFavorites.addEventListener( ResultEvent.RESULT,
resultHandler );
#   dataService.addEventListener(FaultEvent.FAULT, errorHandler);
#   dataService.loadFavorites( myUser.userID, myUser.userHash );
# }

The service being FavoritesProxy.loadFavorites

The two differences I notice is on your result addEventListener, and lack of
a 'source' property.

Hope this helps,
~Aaron

[flexcoders] Re: Newbie, RemoteObject with ActionScript

[twcrone70]

Ok, I guess so.  I really didn't look close enough.  I'm no PHP guy so
I might be overstepping.  The only other thing I see that might be a
problem is that the mxml specifies the 'source' property and the
actionscript does not.  But honestly all my RO's are AS and their
endpoints are Java/Spring services that I specify in the
services-config.xml.  I've never used an MXML RO and I use
ItemResponders rather than even listeners.  My AS code typically looks
like this with the destination etc. configured in the services-config.xml.


var service:RemoteObject = new RemoteObject( destinationId );
var customer:Customer = new Customer();
...
var at:AsyncToken = service.createCustomer( customer );
   
at.addResponder( new Responder( onCustomerCreated, faultHandler ) );



Sorry if I've only confused things more...

Thanks Todd and Aaron,
Adding the .source attribute did the trick.
