[flexcoders] Browser to Flex Debugger connection
Hi all, After compiling my app using the sdk with arg -debug=true i then tried to open the html file in the browser and get the message. Where is your debugger located? -Localhost, -Somewhere else I'm working on localhost so i selected that option and after a few failed attempts i finally get the message 'fp9 was unable to connect to debugger' Can i connect to Flex Builder 2 debugger perspective in this way?

Ralph,
I would be interesting if we could track actionscript-memory
I've run into another interesting related error, that i haven't
confirmed 100% but i'll explain my current conclusion.
i have 2 childs, index's 0 and 1.
0 is selected, then i switch selectedIndex to 1.
Next i remove 0. When i do that i get an out of bounds error and in
the debugger i notice that selectedIndex is still set to 1. Shouldn't
it have updated to 0 since I only now have 1 child?
Anyway i'm digging through the Container Class to understand the
actual behavior now.

Bjorn,
Actually the docs don't lie about that. The removal of a child of
the displaylist will free up the memory it used on the diplaylist
in the FlashAPI, but that's not Actionscript-memory. (I wish I
knew adobe's terms on this, I know they have them ;-) ).
Performance gets increased, because the object doesn't need to be
drawn no more. Since the drawing of everything is the bottleneck
compared to the AVM2, that's actually more true then I'd like ;-)
Ahh, Flash 10, give us hardware support ;-)

Thanks Ralph,
The behavior of the remove/addChild methods are consistent I guess.
I only became perplexed on this issue after the documentation read
that, using removeChild() within the Container would reduce memory
usage and improve performance.
Seems like a case for ViewStack.removeChildAndAllReferences() :)

removeChildAt( ) will only remove the specified object from the

references to objects in containers. You'll have to remove all

run into some problems with this; this was related to states,
though, and this is also something which is by design.

Hi,
How come after calling removeChildAt(selectedIndex) within a
viewstack
the child object still remains?
I've run basic tests to try get this working but no win.
I have a ViewStack based on this;
import mx.containers. ViewStack;
public class ExtVS extends ViewStack
{
// my new selectedIndex()
public function set updateSelectedIndex(index:Number) :void
{
this.createComponentFromDescriptor(this.childDescri ptors
[index],false);
this.validateNow( );
if (index 0)
removeChildAt(selectedIndex);
}
}
And i've set it's creationPolicy=none.
I have 3 children. When i start the app in the debugger my children
look like this in the variables panel;
c1 = childs.MyPanel
c2 = null
c3 = null
By the time a proceed through each stack my debugger variables say;
c1 = childs.MyPanel
c2 = childs.MyBox
c3 = childs.MyCanvas
shouldn't it be
c1 = null
c2 = null
c3 = childs.MyCanvas
Also i am tracking totalMemory usage and i am receiving no benefits
compared to when i was not using removeChild()

[flexcoders] Re: A navigation question.. best practise?
Hi Michelle,
Have a go at using the viewStack container.
create a property:Number in your modelLocator and bind the
selectedIndex property of your viewstack to the property on your model
Locator.
for example
mx:ViewStack
selectedIndex={ModelLocator.getInstance().currentViewIndex}
check out some of the examples on Alex Ulhmanns blog or try
cairngormdocs.org :)

Greetings,
I am having a bit of a problem working out exactly how to navigate
through my application which will be using the Cairngorm 2
architecture.
It currently has the following views: a Login page, a Task List, a
Task and a Finish page. The task list can have any where up to 8
tasks displayed so the user will be switching between Task List and
Task quite often.
The flow between these views will be accessed through button events
(ie, login button, or a start button to start the task etc). There
will be only one View shown to the user at any one time.
I hope that all makes sense.
Anyhoo.
I have read about both the ModelLocator and also
ViewHelper/ViewLocator, and am yet to have that warm and fuzzy moment
where everything just suddenly makes sense, and thus know which is to
be used where.
So my question: What would be the best way to go about handling the
change of Views within this application?
Thanks in advance,

Have a look at overriding the measure() of the Application Class. I think that Application is listening for any browser window size changes and then updating the width and height. Your alternative, if you do not want to resize the actual browser window may be to create a container within mx:Applcation that you can then control.

[flexcoders] Re: cairngorm: managing hundred of views
True indeed. But when dealing with 100+ screens, surely not all view related logic can be contained on a traditional Model. I think Cairngorm leave alot of freedom in terms of how you implement the view. DataBinding is an efficient way of updating the view with business logic. But there is still the requirement of using a view framework. The mx framework offers a awesome components and extending the existing viewstack, box, etc, you can achieve good managable code. But i think there are various view specific patterns to use inconjuction with cairngorm. A key flex advantage in my opinion is that used with cairngorm 2, the difficulty of handling client data has been totally removed. This leaves more time available for enhanced the view and providing Awesome GUI's. I cant wait for Blaze and Robert Penner's AS3 Animation contribution. My current 100+ View Screen app that i'm working on is in AS2, i would so love to be using AS3 instead.

Hi Bjorn
Thanks for taking the time to throw some code into the discussion. The
solution I ended up implementing was similar to the one you
suggest. In my
case the validation was simple, the user either supplies a number
of answers
to a question that is between the minimum and maximum allowed or
they don't.
My point here is that the validation message to the user is more
or less
predefined.
In a more complicated scenario, say a name and address form, it would
appear the model would get messy. Just the name field might have
required,
min max length and [a-z][A-Z] validation rules. Which of these
rules is
broken and on what field would need to be passed back to the view
if you
say, wanted to display an instruction to the user or color the
appropriate
textfield. Having engaged in this discussion I think I have now
come to a
solution for scenarios like this that would maintain the intent of
the MVC
pattern.
On the model you would maintain a collection of objects such as this:
public class ValidationFailedInfo
{
private var _propertyName:String;
private var _message:String;
public function get propertyName():String
{
return _propertyName;
}
public function get message():String
{
return _message;
}
public function ValidationFailedInfo(message:String,
propertyName:String)
{
_message = message;
_propertyName = propertyName;
}
}
That would be populated/cleared by a validate() function (not
shown but it
just applies your rules to the properties of the model). You would
also have
a method such as:
public function
GetValidationMessages(propertyName:String):Array
{
validate();
var messageArr:Array = new Array();
var currValInfo:ValidationFailedInfo = null;
for(var x:int = 0; x_validationInfoList.length; x++)
{
curValInfo =
ValidationFailedInfo(_validationInfoList[x]);
if(currValInfo.propertyName == propertyName)
{
messageArr.push(currValInfo.message);
}
}
return messageArr;
}
You could use this to determine whether each field is valid and if
not why
not. All of the validation rules would remain in the model as
would the
message strings that you return. If for example your application
supports 10
languages, storing all of the language logic in the view would be a
maintenance nightmare wheras this would allow all of that to stay
in the
model.
Thanks for all of your contributions. Can I also take the
opportunity to
say that this is the most welcoming and active group that I have
participated in... Keep it up [image: :D]

Hi Neil, Indeed, ideally you create an XML instance on your model. It would make sense to have this loaded XML a single point of reference throughout the application. Bjorn, --- In flexcoders@yahoogroups.com, nwebb [EMAIL PROTECTED] wrote: Hi, I'm loading XML in to Flex2 at compile-time and would like to bind label properties of certain modes to a Tree list display. The docs say that you cannot (currently) bind to properties of an XML instance (the XML class is not of type IEventDispatcher) so I thought I would try loading the XML in to Model instance instead, using: mx:Model id=menuItems source=xml/menuOptions.xml / My test XML looks like this: ?xml version='1.0' ? menu folder label=Flex 2 item label=Tutorial 1 Hello/item item label=Tutorial 2 / item label=Tutorial 3 / /folder /menu I don't think model instances support attributes though, so while trace( menuItems.item[0]) works, I can't seem to access the label attribute. Could someone confirm that this is right, and if so, are there any better suggested methods to use, or do i just need to load the xml in to an XML instance, and then use E4X to pull out the label attributes and assign them to bindable vars of my own creation?

[flexcoders] Re: Cairngorm2: ViewLocator - ViewHelper
Hi Tim, I am also considering the benefits of using viewHelpers. Here's what i got out of it. encapsulating all the logic necessary for interrogating and updating a particular View into a single helper class Why would the Command need to interrogate the View. A Command is always essentially created by the View and dispatched event data updates the Command. On Command remote handlers, the Command updates the model. I have been using explict setters on the view to initiate data-binding between model and view in mxml. Then it is View that is responsible for dispatching events throughout an application and that it is the View which will always drive the app. Regards Bjorn Schultheiss --- In flexcoders@yahoogroups.com, Tim Hoff [EMAIL PROTECTED] wrote: I've recently been toying with the concepts of ViewHelper vs. ViewLocator. Alex Ulmann posted, the ViewHelper adds and removes itself from the ViewLocator, in his Cairngorm 2 (for Flex 2) Overview and Migration Path. I haven't seen any examples yet that illustrate this method. Understandably, the example pool and documentation for this kind of thing is small but growing. So, I was wondering if the authors of Cairngorm had any advise/guidance for this topic. Of course it's a matter of scale, but in an enterprise application, what is recommended as best practice for the use of ViewLocator and/or ViewHelpers? I'm sure that there are forthcoming books that cover this area, but feedback here might promote better understanding. Best regards, Tim Hoff Yahoo!

[flexcoders] Re: app startup / load times
Hi Hank I think people will wait. Once it's loaded it can be cached. Ted once wrote a blog about RSL that achieved this. While people are thinking about do i wait for it to load or not, by the time it does you got em. That's my opinion. regards, Bjorn Schultheiss --- In flexcoders@yahoogroups.com, hank williams [EMAIL PROTECTED] wrote: For the first time since I started playing with flex (a couple of weeks) I checked out the size of my app, which is currently 477k. My app isnt that big, so I presume most of that is just the size of the framework. I am just wondering what do people think about that in terms of user start up time. For a user with a 500kbps connection that is about 8 seconds before the app is loaded. Are people doing loaders to get things started? is there an accepted strategy for how to deal with this? There was another thread recently about how people shouldnt use flex for websites and one person provided aesthetic reasons. In my mind, if there is a reason (and I am not arguing that there is) but if there is a reason not to use it for websites it would be the file size. 10 seconds seems like a long time to make someone wait before they see something. On the other hand perhaps I am underestimating the average connection speed. Anyway, like I said I would just like to get peoples thoughts on this issue.

[flexcoders] F2 CF FMS AMF encoding problems
Hi guys, I'm setting up a basic test application. The app initially performs a login with CF where I pass a LoginVO instance straight into CF. The new AMF3 handles the typed object beautifully and CF easily returns me back a new LoginVO instance. Next I attempt to make a connection to Flash Media Server. This is the error message I receive. code : NetConnection.Connect.Failed description : objectEncoding error If I set NetConnection.defaultObjectEncoding = flash.net.ObjectEncoding.AMF0; My connection to FMS works, but my handling of the LoginVO instances with Coldfusion no longer works (for obvious reasons). Is there a workaround for this?
