Re: [flexcoders] Cairngorm Question
You do have acess to the model. The combo 2 will be populated with some data. Put that into the model and bind combo 2 to the model I'm not sure what you actually want to do but it doesn't look like you need cairgorm to do that ... C From: skusunam skusu...@rlpt.com To: flexcoders@yahoogroups.com Sent: Thursday, April 9, 2009 7:53:48 PM 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] Cairngorm - Question on using ResultHandler
You are doing things the right way. If after you login you want to do some
more, look at the SequenceCommand.
You would basically add a executeNextCommand() statement after your
model.workflowState statement.

Subject: [flexcoders] Cairngorm - Question on using ResultHandler
Hi,
I have a question using Cairngorm and Commands. I am new to it but its making
more sense to me each day at least it seems that way.
I have the following in my LoginCommand.as
public function result( data:Object ):void {
var event:ResultEvent = data as ResultEvent;
if (event.result.length 0) {
model.workflowState = ModelLocator.VIEWING_HOMEPAGE;
}
else {
model.login.statusMsg = Your login credentials are invalid, please
try again.;
}
}
1. Is there anything wrong with the way I am doing the above?
2. I would like to call some other remote objects s! o I can populate some
datagrids after the user has been authenticated and then load the home page of
the app as I am doing above.

RE: [flexcoders] Cairngorm question
Steven:
To my understanding, correct me if I am wrong, there are
somewhat to significant changes from
Cairngorm 0.99 and Cairngorm 2.0. I realize some of
this is due to Flex 2, but my question is
will there be an updated version of your 6-Part article(s)
for Cairngorm 2?
Or will that information be contained in documentation when
Cairngorm 2 is released?
Thanking you in advance,

RE: [flexcoders] Cairngorm Question
I've only worked with some of the Cairngorm classes that were described
in the Flex book. You're going to have to have a local model for each
sub app instance. Your event that is fired after the search being
complete can also contain instance data about the Sub app that called it
and update your local model with the returning data accordingly. That
way you can map the returning data to the calling Search instance, and
its associated parent sub-application.
When you invoke a RemoteObject you can stipulate where the returning
data is going to go using the returned pendingCall instance which can
point to a result handler which can be local to the calling search
instance, which in turn updates your local model.
var pendingCall = myRemoteObject.myMethod(arg1,arg2,etc.);
pendingCall.resultHandler =
mx.utils.Delegate.create(mySubApp,myReturnFunction);
function myReturnFunction(event):Void
{
//update your local model instance here;
}

Subject: [flexcoders] Cairngorm Question
We have been developing a fairly large application using Flex 1.5 and
the Cairngorm framework, and have recently run across what could be a
large roadblock. Our application has many sub-applications the user can
choose to run from a menu in the main application. To implement this we
are dynamically creating the children the user selects in a view stack.
All of these sub-applications rely on a particular search screen that
allows the user to find a particular person in our database. The problem
is that the sub-applications are bound to the selection the user makes
in the search screen, and are all reacting to the same events (which are
broadcast from the search screen). We would like the search screens to
function as separate instances. For example, if I broadcast a change
event from the search screen, all of the open sub-applications will
catch the event and change all of their displayed information to reflect
that of the most recently selected person. Our problem appears to stem
from the way the EventBroadcaster and FrontController are designed. All
events are broadcast in the same EventBroadcaster using the
getInstance() method, thus everything is listening for everything.
Can anyone who is familiar with the intricacies of Cairngorm propose a
way to deal with this problem? We would like to be able to return the
information about the selected person only to the sub-application that
invoked the search screen. Perhaps it is not possible to do this using
Cairngorm, and we would appreciate knowing that, too.
If anyone has a different/better solution, we'd love to hear about it.
Thanks in advance.

Re: [flexcoders] Cairngorm Question
Hi fowleryj, Why have the same problem here. And one solutionfor usea diferents commands you have to use diferentes names for each application, beacause the FrontController add a listener in a single static var eventBroadcaster. But if your application is realy big I recommend to you rewrite some classes in the cairngorm framework. For example you can rewrite te EventBroadcaster and FrontController classes creating a FrontControllerLocator. This FrontControllerLocator can be implemented like the ViewLocator. You set IDs for each controller and use this IDs to call the EventBroadcaster. Did you understood? I did the same with the services creating a ServiceHelper and a ServiceLocator, and this can help you to implements the FrontControllerLocator. I hope that can solve your problems. Let me know if it`s works and sorry for my poor english. Hugs.

Re: [flexcoders] Cairngorm Question
Hi YJ, RocketBoots is working with a development team on a large (100s of classes) Flex 1.5 Cairngorm application at the moment with potentially many instances of the same sub-application (we call them workspaces) around at the same time - e.g. two searches, three articles, a calculator etc. Here's our solution, which is working nicely. Each type of workspace has it's own viewHelper class. Each workspace instance has it's own viewHelper instance. Because there are multiple instances it was going to be difficult to use the ViewLocator and ModelLocator, so we didn't. Instead, when workspace instance X broadcasts an event, we include a reference to the workspace's viewHelper in the event data. The command's execute method caches this viewHelper in an instance variable, and its onResult method uses the same viewHelper to display the results. The viewHelper instance also holds our model, using instance instead of static variables (although we can imagine using statics in some situations, for bits of the model shared across all workspaces). Happy to answer further questions about this approach - this one has been in the backlog of things to blog for a while.

For example, if I broadcast a change event from the search screen, all of the open sub-applications will catch the event and change all of their displayed information to reflect that of the most recently selected person. Our problem appears to stem from the way the EventBroadcaster and FrontController are designed. All events are broadcast in the same EventBroadcaster using the getInstance() method, thus everything is listening for everything. Can anyone who is familiar with the intricacies of Cairngorm propose a way to deal with this problem? We would like to be able to return the information about the selected person only to the sub-application that invoked the search screen. Perhaps it is not possible to do this using Cairngorm, and we would appreciate knowing that, too. If anyone has a different/better solution, we'd love to hear about it. Thanks in advance. -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

RE: [flexcoders] Cairngorm Question about the Store Example
Libby,
I don't have the source in-front of me, but if you have a
GraphicalProductList component, that is advertising that it broadcasts a
select event, then I'd be looking for the instantation of that component
to find the event being handled, eg:
namespace:GraphicalProductList select=yourOwnHandlerHere() /
The GraphicalProductList will broadcast the event (or use a helper
class, as seems to be the case here, to broadcast the event) but the
parent of that instance of the class will be the place where the event
is handled.
Make sense ?
Steven

Subject: [flexcoders] Cairngorm Question about the Store Example
In GraphicalProductListViewHelper.as, there is this line:
view.dispatchEvent( { type:select } );
In the view, which is GraphicalProductList.mxml, it
advertises that it broadcasts this event:
mx:Metadata
[Event(select)]
/mx:Metadata
Where is this event actually caught or handled? I have read
thru all the files several times and cannot find it.
The reason I am looking is that in my Master/Detail screen,
when Master updates the Model, the Detail, that is bound to
the model, doesn't notice it. I think I need to broadcast
that a change has occurred, they way they did.
thanks,
Libby

RE: [flexcoders] [Cairngorm] - Question about ViewHelpers
Hi,
A ViewHelper is bound to a specific Form/View. If your case you can do it two
ways. You can use one ViewHelper to set the data on the different fields OR the
command can save the user data on a ModelLocator and that model is bound to the
varius controls, like so:
mx:TextInput id=name text={ModelLocator.user.name} /
mx:TextInput id=email text={ModelLocator.user.email} /
As for the header, you can bind its value as well, instead of having to set it
everytime, like so:
mx:Label text={name.text} /
Hope that helps!

Subject: [flexcoders] [Cairngorm] - Question about ViewHelpers
Hi guys,
I was wondering about the following...
Say you have a GetUserCommand the retrieves a user from the db and then
updates 2 views: a UserForm where the user's data is shown and the
application's HeaderForm where the name of the current user is
displayed. How would you handle updating these 2 views?
I was thinking:
1) Update the views from within the command through 2 ViewHelpers
(UserFormViewHelper, HeaderFormViewHelper)
2) Create one ViewHelper named UserViewHelper that you call inside the
command. In that UserViewHelper the 2 forms are updated.
This raises another question: Is a ViewHelper bound to a Form/View or to
a business entity like User in this case?
thx for your time !

Re: [flexcoders] [Cairngorm] - Question about ViewHelpers
Hi Dimitros,
thx for the feedback. Things are more clear now.
Just another question: How would you handle the same situation in a
Flash application? Would it be a good idea to let the Forms/Views
register with the ModelLocator for changes in the model? Or does that
give the ModelLocator too much responsibility.
I see how the binding is done automaticly by Flex and that rocks...if
only Flash could do that in such an easy way.

This "service" must be running, in the background, even if im visually working in another part of the application, entering some data for new providers or whatever. So the question is, where is the best place to initialise these services? Or how can I place/work with these services within this arquitecture?My choice would probably be to initialise evrything inside a "initialise()" function in the model locator and then use some public var there to control msgs and status of this "service" and then bind the chat components to these vars.I hope someone can help chosing the best option.Thanks all in advance.-- Alberto Albericio SalvadorAura S.A.

RE: [flexcoders] Cairngorm Question.
Title: Message
The
way Cairngorm current architects the ViewHelper is that itrequires
eachViewHelper to register itself to the ViewLocator under a unique name.
Therefore if you are attaching theview dynamically in a repeater and using
the samevalue in the 'name' attributefor the ViewHelpers
thenthe ViewLoactor will throw an error.
One
approach to your solution is to have the each of your views bubble up its
methods to the parent view that the repeater exists in.
For
example (in code babble).
MyMainView.mxml
mx:script
public activeChild : MovieClip = null;
function parentHandleMethod(evt)
{
// store current child view to
local var
activeChild =
evt.target'
// do server
call
}
/ms:script
mx:repeater
me:mychildView
/mx:repeater
...
MyChildView.mxml
mx:Metadata
[Event("onCustomEvent1")]
[Event("onCustomEvent2")]
/mx:Metadata
mx:Button click="this.dispatchEvent({type='onCustomEvent1',
otherAttributes=''})"
In
this example instead of having the child view handle the logic itself
(communicating to the server) it tells the parent too. Or more correctly says
'someone please do this for me' the parent will know which of the child views to
get the data from since the dispatch event automatically keeps track of the
target in which the event was dispatch from.
This
is just a suggestion. There are other options out there, perhaps better or more
correct then this approach.

RE: [flexcoders] Cairngorm Question.
Title: Message
Well.
My thought is 'Who would know what child needed the work done?' The view
locator's need to have the view helper name be unique is so that it can locate
the view. A command has to be 100% sure what view towork with to get the
data to properly make the call out to the server. Therefore my thought is that
the safer bet would be to have the command talk to the parent to either a) get
the data or b) get the name of the child.
Anyway, those are just my thoughts to why I would approach the situation
the way I outlined. My judgment of clean has a lot to do with the ability to
maintain the application and as much as possible keeping the interdepancy
between my view files as possible. Loose coupling.

and using the samevalue in the 'name' attributefor the ViewHelpers
thenthe ViewLoactor will throw an error.
One
approach to your solution is to have the each of your views bubble up its
methods to the parent view that the repeater exists in.
For
example (in code babble).
MyMainView.mxml
mx:script
public activeChild : MovieClip =
null;
function parentHandleMethod(evt)
{
// store current child view
to local var
activeChild =
evt.target'
// do server
call
}
/ms:script
mx:repeater
me:mychildView
/mx:repeater
...
MyChildView.mxml
mx:Metadata
[Event("onCustomEvent1")]
[Event("onCustomEvent2")]
/mx:Metadata
mx:Button click="this.dispatchEvent({type='onCustomEvent1',
otherAttributes=''})"
In
this example instead of having the child view handle the logic itself
(communicating to the server) it tells the parent too. Or more correctly says
'someone please do this for me' the parent will know which of the child views
to get the data from since the dispatch event automatically keeps track of the
target in which the event was dispatch from.
This
is just a suggestion. There are other options out there, perhaps better or
more correct then this approach.

Question.
Hi
all,
I am using the
Cairngorm plataform but had a small question. How can I use the viewhelper
technique when I attach view dynamicaly? For example I have a mxml component
and put a view helper attached to it and use this component on a repeater
and 5 instances are made. When I call the getViewHelper method which of
those 5 reference will it give me? Any help would be
apreaciated.

That
is 'keeping the interdepancy between my view files as few as
possible'.

Well. My thought is 'Who would know what child needed the work done?'
The view locator's need to have the view helper name be unique is so that it
can locate the view. A command has to be 100% sure what view towork with
to get the data to properly make the call out to the server. Therefore my
thought is that the safer bet would be to have the command talk to the parent
to either a) get the data or b) get the name of the child.
Anyway, those are just my thoughts to why I would approach the
situation the way I outlined. My judgment of clean has a lot to do with the
ability to maintain the application and as much as possible keeping the
interdepancy between my view files as possible. Loose
coupling.

The way Cairngorm current architects the ViewHelper is that
itrequires eachViewHelper to register itself to the ViewLocator
under a unique name. Therefore if you are attaching theview
dynamically in a repeater and using the samevalue in the 'name'
attributefor the ViewHelpers thenthe ViewLoactor will throw an
error.
One approach to your solution is to have the each of your views
bubble up its methods to the parent view that the repeater exists in.

MyMainView.mxml
mx:script
public activeChild : MovieClip =
null;
function
parentHandleMethod(evt)
{
// store current child
view to local var
activeChild =
evt.target'
// do server
call
}
/ms:script
mx:repeater
me:mychildView
/mx:repeater
...
MyChildView.mxml
mx:Metadata
[Event("onCustomEvent1")]
[Event("onCustomEvent2")]
/mx:Metadata
mx:Button click="this.dispatchEvent({type='onCustomEvent1',
otherAttributes=''})"
