I tried to dump myServices via:
<code>Dumper.dump(mx.core.Application.application.myServices);</code>
during the Delegate constructor, and it came up 'undefined'.
I tried a creationComplete and an Initialize event to dump
siteDataServices upon startup of the main mxml file. Both had this
to say:
[INFO]: (Object)
log: (Object)
level: 1 (Number)
name: RemoteObject_AMF (String)
__conn: (Object)
contentType: application/x-fcs (String)
_headerAdded: false (Boolean)
_config: (Object)
m_debug: true (Boolean)
app_server: (Object)
coldfusion: true (Boolean)
amfheaders: false (Boolean)
amf: false (Boolean)
httpheaders: false (Boolean)
recordset: true (Boolean)
error: true (Boolean)
trace: true (Boolean)
_debug: true (Boolean)
realtime_server: (Object)

recordset: true (Boolean)

_debug: true (Boolean)
_debug: true (Boolean)
_protocol: http (String)
_id: 0 (Number)
netDebugProxyFunctions: true (Boolean)
_allowRes: true (Boolean)
__serviceName: com.foo.test.business.SiteMaintenanceDelegate
(String)
__responder: (Object)
__obj: undefined (undefined)
__onFault: _resp5_fault (String)
__onResult: _resp5_result (String)
__name: siteDataServices (String)
__showBusyCursor: true (Boolean)
__concurrency: 0 (Number)
__parentDocument: undefined (undefined)
Looks like it's available at both initialization and creationComplete
time frames.
I'm curious why the examples taken from the books website would prove
to be this difficult to implement.
When you say "pass the service to your delegate constructor as a
parameter", do you mean as a string? Like the following:
public function ReviewKeywordsCommand() {
this.delegate = new SDMDelegate( this, mx.core.Application.\
application.myServices.siteDataServices );
}
sorry if these are really basic questions, but I'm new to RIA
development.
Thanks,
Geoff
