[flexcoders] Re: RemoteObject Issue
How crazy is this! I took your advise and moved a few things
around. In my Unit test file I changed it to:
mx:Application xmlns:mx=http://www.macromedia.com/2003/mxml
xmlns:sdm=sdm.*
xmlns:services=services.*
services:Services id=myServices/ ---changed
sdm:SiteDataMaint/ ---changed
/mx:Application
Basically just swapping the order of the services and sdm tag made it
work.
Thanks for all your efforts Doug!

It seems like siteDataServices hasn't been created at the time the
SMDelegate constructor is being called. You'll need to dig through
your code to find out why, e.g. check where you're calling
ReviewKeywordsCommand(), and possibly call the constructor at some
other point when you know the remote object has been created.
Regarding parameter passing, the constructor example you gave is
exactly what I had in mind. The value you're passing isn't a string
though, it's a reference to the RemoteObject that you gave the id
siteDataServices to. Personally, I'd probably pass the service
as a
parameter, but as long as the delegate constructor is called only
after you know the service object exists, either way should work.
I hope this helps, and another thing to note is that the work you're
doing now to implement these design patterns will pay off down the
road - especially if you're implementing a large-scale app.

My guess would be that SDMDelegate's constructor can't access your
siteDataServices RemoteObject through mx.core.Application.application.
Try this.service = parentApplication.myServices.siteDataServices
instead, or pass the service as a parameter to the constructor as you
do with the responder.

nothing on all accounts.

[flexcoders] Re: RemoteObject Issue
It seems like siteDataServices hasn't been created at the time the
SMDelegate constructor is being called. You'll need to dig through
your code to find out why, e.g. check where you're calling
ReviewKeywordsCommand(), and possibly call the constructor at some
other point when you know the remote object has been created.
Regarding parameter passing, the constructor example you gave is
exactly what I had in mind. The value you're passing isn't a string
though, it's a reference to the RemoteObject that you gave the id
siteDataServices to. Personally, I'd probably pass the service as a
parameter, but as long as the delegate constructor is called only
after you know the service object exists, either way should work.
I hope this helps, and another thing to note is that the work you're
doing now to implement these design patterns will pay off down the
road - especially if you're implementing a large-scale app.

I tried a creationComplete and an Initialize event to dump
siteDataServices upon startup of the main mxml file. Both had this
to say:

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,

The parentApplication property is a reference to the Application
object (the nesting refers to applications loaded within other
applications with the Loader control and probably doesn't apply to
your case), but it's a property of mx.core.UIObject, which your
SDMDelegate obviously isn't extending and probably shouldn't. Have
you tried dumping mx.core.Application.application.myServices in the
delegate constructor to see if it exists at that point? You could
also try adding a creationComplete event to the application to
determine exactly when the siteDataServices remote object is
available; something like
creationComplete=Dumper.dump(myServices.siteDataServices) should
do it.
It might be your best bet to pass the service to your delegate
constructor as a parameter.

Hmm
I replaced the service assignment with:
this.service = parentApplication.myServices.siteDataServices;
But I get the following error:
There is no property with the name 'parentApplication'.
Looking at the docs, parentApplication looks like it's intended
to
walk up the tree of multiple application nested within
themselves. I
don't think that applys to this case since I only have 1 mxml
file
with the mx:Application tag. Please correct me if I've
misunderstood this.
Thanks,
