[flexcoders] Re: Cairngorm Question
Wrap your head around the idea that the model controls the view. Even the
data portions. You should bind your combo box dataprovider to the model
property storing that data (from server based on combo box 1 selection). Why
you don't need cairngorm for enabling? You can just set you're 2nd combo box's
enabled property to {combobox1.selectedIndex gt; -1}. An alternative using
cairngorm is if your dataprovider (in the model) is null, disable combo box 2,
if it has data, enable it.
Hope this helps!

Subject: [flexcoders] Cairngorm Question
Hello Group,
This is my first question on this group and I have been referring to this
group for all my technical challenges with Flex (started using 1 month back).
Thanks for such a nice group and support.
I have a complex screen where I have 2 Combo boxes and by default Combo-2 is
disabled and will be enabled only when user selects Combo-1 and Server
returns any Objects for Combo-2 otherwise it will be still disabled.
I have defined an Event `LoadCombo2Event' which is dispatched when user
selects an entry from Combo-1 and the results will be handled in
`LoadComb2Command' . I do not have access to Combo2 in this command to Enable
or Disable?
How do we handle this case using Cairngorm?
Thanks,
Sre
Re: [flexcoders] Re: Cairngorm Question
Nathan Claudieu,
Thanks for the response. After I posted my question I started reading
and thinking how to correct this and came up with the same idea Nathan
suggested. I started refactoring everything and so far it is going
great.

its returning a list of objects and u need to access the first, second, etc..

Hi Leon,
A couple things here.
1) In ANT you can, at build time, replace tokenized values in any
file. We do this quite a lot. So for instance you could modify your
flex-config to do
amf-gateway/@webappname@/amfgateway/amf-gateway
Now when you do your build and copy the file in, you can do
replacements of the @token@ token. Something like:
copy todir=${build.dir}
fileset dir=${src.dir}/
filterset
filter token=webappname value=${web.app.name}/
/filterset
/copy
You can then prompt for the web app name during the build.
2) If you cant do this during the build you can do it at runtime in a
few ways. First would be a servlet, listed to load at startup and
placed in order 1. The servlet would find out its current context,
then modify the flex-config.xml file itself replacing the web app name
with whatever the name is of its own file. This would be purely J2EE
agnostic. If though you're using Tomcat you can also do this with a
Tomcat listener. Effectively the listener fires at server boot and
you could again replace values. But the prior solution would work on
any app server and without messing with your clients servers.
I hope that helps.

Ok, we've gone down the route of using mxmlc.jar for precompilation.
The reason is purely to include data within the SWF to save a return
trip to the server - and also to reduce the load on the server at
initial request time.
Our process is essentially running a series of Ant tasks that firstly
compile all our Java classes, secondly precompile our MXML and lastly
create a WAR ready for deployment.
Since the MXML is precompiled without using the Flex server
whatsoever,
we need to specify the gateway to the compiler - this is currently
done
in flex-config.xml. At present we can't find a way to make this
relative - i.e. not to include the name of the root directory. For
example:
amf-gateway/myFlexApp/amfgateway/amf-gateway
Ideally what we'd like is:
amf-gateway./amfgateway/amf-gateway
The reason why we'd like this is - when we create a WAR and deploy to
our customers, we don't have control over what they choose to name the
WAR file. Since the name of the WAR file relates to the root
directory
name and we can't find a way to make that value relative, we have a
hugs
issue here!
Has anyone come across this or have any ideas we could try to get
around
it?
Thanks

there's a learning curve.. but it's a powerful technology and one

[flexcoders] Re: Cairngorm Question
Hi Leon,
A couple things here.
1) In ANT you can, at build time, replace tokenized values in any
file. We do this quite a lot. So for instance you could modify your
flex-config to do
amf-gateway/@webappname@/amfgateway/amf-gateway
Now when you do your build and copy the file in, you can do
replacements of the @token@ token. Something like:
copy todir=${build.dir}
fileset dir=${src.dir}/
filterset
filter token=webappname value=${web.app.name}/
/filterset
/copy
You can then prompt for the web app name during the build.
2) If you cant do this during the build you can do it at runtime in a
few ways. First would be a servlet, listed to load at startup and
placed in order 1. The servlet would find out its current context,
then modify the flex-config.xml file itself replacing the web app name
with whatever the name is of its own file. This would be purely J2EE
agnostic. If though you're using Tomcat you can also do this with a
Tomcat listener. Effectively the listener fires at server boot and
you could again replace values. But the prior solution would work on
any app server and without messing with your clients servers.
I hope that helps.

[flexcoders] Re: Cairngorm Question
Hi Robin,
Thanks again for all of the help so far.
The next question I have is for any and all Flexcoders whose
application is growing to a rather large size (100s of files, etc).
How are you keeping your compile time down? Our application takes
between 30 seconds to 1 minute to refresh, and this seems rather high.
Thank you,
YJ

Hi Robin,
We've started implementing your ideas to solve the multiple

problem. Forgive me for the continued questions, but we're wondering
how you are handling the propagation of the data contained in the
onResult() method in the Command.
For instance, one of our sub-applications is laid out in the
following
manner (with generic names and labels in this case):
FileOne.mxml
mx:HBox
mx:ViewStack
search:SearchScreen id=searchScreen label=Open/
mx:Panel id=infoPanel label=Information
mx:TabNavigator id=tabNavigator
view:TabOne label=tab1/
registrar:TabTwo label=tab2/
/mx:TabNavigator
/mx:Panel
/mx:ViewStack

So in FileOneViewHelper.as, we broadcast an event to find the results
of the user's search criteria, and in the Command's onResult(), we
call the particular view helper's (in this case, FileOneViewHelper's)
handleEvent() method, passing it the necessary data.
Once the user selects the match they want to work with, we need to
propagate that match's data to the tabs in the TabNavigator, so that
the tabs can fill themselves appropriately. Previously we were doing
this by broadcasting an event, but now we are faced with the issue of
passing the data along to the various tabs (TabOne and TabTwo, for
instance) from the parent ViewHelper. We've explored a few options
and they all seem to involve significant amounts of hardcoding to
drill down through the hierarchy. If it's not too much to ask, would
you share with us your method of passing the data from for example
a TabNavigator to its tabs?
Thank you again for all of the time you've spent helping us with
this.
If you ever find yourselves in the Southern United States, drinks are

[flexcoders] Re: Cairngorm Question
We are firm believers of precompiling our applications when in
production rather then using the JIT MXML compiler. We are big
proponents of ANT and automate the builds of not only the MXML but of
the entire production server. With one command line we build the
entire site ready to go into production. Its very powerful and has an
immeasureable impact on productivity of our teams. We've built some
very nice macros in ant that make building Flex applications very simple.
IMHO the JIT compiler is not how you want to run your production
application.

For large applications I believe you have to do a
bit of refactoring and start playing with RSLs.
Aside of the obvious reasons of performance gain
during development by eliminating unnecessary recompilation it kind of force you
to eliminate weak links and create "layered" components - based view of the
application. It might save additional time if/when the team/project grows to
extent that versioning and areas of responsibilities wouldmake single SWF
not practical.

Command's onResult(), we call the particular view helper's (in this
case, FileOneViewHelper's) handleEvent() method, passing it the
necessary data. Once the user selects the match they want to
work with, we need to propagate that match's data to the tabs in the
TabNavigator, so that the tabs can fill themselves appropriately.

Re: [flexcoders] Re: Cairngorm Question
Hi YJ,
Sure - the Cairngorm code is unmodified. For instance, in your view
you might have:
private var viewHelper : OurViewHelper;
private var searchDefinition : SearchDefinitionVO;
...
EventBroadcaster.getInstance().broadcastEvent
(OurController.SEARCH_COMMAND,
{viewHelper:viewHelper, searchDefinition:searchDefinition});
And in the command:
private var cachedViewHelper : OurViewHelper;
function execute(event : Event) : Void {
cachedViewHelper = event.data.viewHelper;
delegate.search(event.data.searchDefinition);
}
public function onResult(event : Object) : Void {
cachedViewHelper.showSearchResult(SearchResultCollectionVO
(event.result));
}
There is a bit more to talk about regarding the initial creation of
the view helpers and views which I hope to blog soon, but if you have
more specific questions fire away.
Cheers,
Robin

RE: [flexcoders] Re: Cairngorm question
Hi Alberto, in addition to what Dan said, you could create an object similar to Business Delegates used for request/response remote calls - in applications that we have developed, we call these Listeners. These listeners provide control and protection for your server push remote services. In here, you could implement functionality as recovery plans, disconnecting etc. In these listeners, we would typically subscribe to server-side shared objects. When we receive notification of changes to the shared object, we then convert untyped FlashComm data into VOs, before using the EventBroadcaster in our listener to broadcast events plus data. So the listener is really just another way of injecting an event into the Cairngorm architecture, other than a user-gesture. In this way, the commands are unaware as to whether the events that called them, and the data accompanying these events, was pushed from the server (via FlashComm) or generated on the client. Everything else about your Cairngorm architecture remains the same - using the ModelLocator for instance, to have your commands updating the model, and binding the view to the state of your model. Depending on the complexity of your application, we might suggest further refactorings, i.e. outsourcing functionality of listeners to other classes such as recovery plans.

Re: [flexcoders] Re: Cairngorm question
Hi Alex, I like the idea of Listeners and they way you point to manage server pushes injecting events and data to the Cairngorm architecture. Mainly because server pushes are treat just like if they were data from a user-gesture. If possible, send me a sample code for one of these Listeners, just a short one so I can see how to initialise the subscription and how handlers for server pushes are defined. I can imagine it's somehow similar to a business delegate class calling a remoteobject but I dont see how to leave these services in the background listening and waiting for server pushes. Thanks for your help Alex.

Re: [flexcoders] Re: Cairngorm question
Hi again,
Im trying to create a business delegate class for handling a connection
to, for example, an xml socket.
When trying to delegate onXML to the responder it keeps on saying there
is not such property on the responder, but of course there is. If I
define the function inside de business delegate class, it works
(changing responder.myOnXML for myOnXML, of course)
I have something like this on my command class:
class org.nevis.cairngorm.prexon.commands.SubscribeCommand implements
Command, Responder {
public function execute( event:Event ) : Void {
var delegate: SubscriberDelegate = new SubscriberDelegate( this );
delegate.subscribe( );
}
public function myOnXML( event : Object ): Void {
mx.core.Application.alert(RESPONDER OK);
}
..
}
And the business delegate has:
this.responder = responder; (the parameter for the class)
myListener.onXML = Delegate.create( responder, responder.myOnXML );
...
What Im I doing wrong? Is it okay setting a responder here? Cause I have
to define a result and fault handler im never using for this kind of
services...

Alberto,
this seems a fair approach to me, you may also want to include some
logic to disconnect from the flash comm server when you know you are
not interested in receiving updates and maybe even a 'recovery plan'
for the service should the connection to the FCS be broken.

RE: [flexcoders] Re: Cairngorm question
Alberto,
your responder is probably of type Responder and Responder is the interface
that only contains onResult and onFault. See Cairngorm docs. I suggest you
implement the communication from your listener to the command via
EventBroadcaster.
