[flexcoders] Re: Question about using [RemoteClass(alias=...)]

[John Mesheimer]

Forgive me, I be a dingbat...

By setting the [RemoteClass(alias=...)] line, the thing I got back from
the server was not an ArrayCollection of generic Objects, but of strongly
typed Review (AS) objects, which didn't need any casting.

All solved now. Nothing to see here...

 I have an ActionScript class that creates a custom Review object, like so:

 / Review.as
 / Taken from one of Adobe's online samples
 package samples.restaurant
 {
 import mx.formatters.DateFormatter;

 // [RemoteClass(alias=samples.restaurant.Review)]
 [Bindable]
 public class Review
 {
 public function Review(source:Object=null)
 {
 // some date formatting stuff happens here
 }

 public var restaurantId:int;
 public var restaurantName:String;
 public var restaurant:Object;
 public var reviewDate:Date;
 public var reviewer:String;
 public var rating:Number;
 public var title:String;
 public var reviewText:String;
 public var email:String;

 }

 }

 This class lets me take an ArrayCollection of generic Objects from the
 server, loop through it with something like new Review(source[i]) and get
 a bunch of Review objects in an ArrayCollection. Works perfectly.

 I also need to be able to write a Review object (a Java object) to the
 server, so I add [RemoteClass(alias=samples.restaurant.Review)] above
 the ActionScript class declaration. This way I can declare a public var
 review:Review, call an addReview(review) on my RemoteObject service, and
 my server receives a Review Java object. This works perfectly too.

 The problem is that once I add this [RemoteClass(alias=...)] line,
 doing new Review(source[i]) no longer works as expected. Given the same
 ArrayCollection of generic Objects as before, new Review(source[i]) will
 still create a Review object, but now all its properties are null.

 If I comment out the [RemoteClass(alias=...)] line I can properly cast
 generic objects to Review objects again (but then I am no longer able to
 send a Review Java object to the server).

 Is this the way it's supposed to work? (I hope I've stated my problem
 clearly.) How can I accomplish both tasks using a single Review.as class?

 Thanks for any help, folks.

[Arik de Guzman]

thank you alex for replying, i was able to handle the exiting event but i would 
like to prompt a confirmation exit when ctrl+f4 is pressed before the actual 
exit. like before closing the app it would likely have an alert of confirmation 
of exit.

Don’t extend RichTextEditor.  It is an mxml file.  Just copy it and edit the

This is a lot for me, and I don't expect you or others have the answers but I

how to do that...

It's a brain teaser and I am working on it a piece at a time.

If anyone has a shortcut I'd take it.

We do the same thing.  See this screen shot:

http://www.reynacho.com/wp-content/uploads/2009/05/cse-charting.jpg

There's a lot more than just a moving average and bollinger bands there but
those are parts of it.  In order to get this data, we first tapped into a
feed which you have to pay good money for.  I believe we are using NxCore
which I think is a DTN product.  You might look into that but I know there
are others as well.

For the data, we pass data into a java library called ta-lib:
http://ta-lib.org/

It has methods for moving averages, deviations, etc.  We found that the
calculations for our app were simply too intense to be done on the client.
But, we have 5-7 years worth of data that we are looking at for calculations
so you might not run into the same bottleneck we had

[flexcoders] Re: Question for Math guys/girls

[Netaman]

What if the user should make the line shorter then 100 pixels does the marker 
go away, I don't think it's math more like an array collection of markers. You 
save the x,y coordinates of the marker, as the line gets bigger or smaller you 
replace the markers that fit on the line from the array's x,y coordinates... 
Add an click event listener to your container with the line, then create a 
function to add the x,y coordinates to an array. Without a code example I can 
only guess what you are trying to accomplish. You can create a timer to refresh 
your container with the markers from the array, or generate another event when 
the line changes length, or you add another marker.

Do you have any code to share?

Does the angle of the line ever change? Or is it always 45 or 0? If the
angle changes then the X coordinate will change for any points on the line.

I hope that you are not scaling a MC to grow/shrink the line.  Rather you
should be drawing the line with every mouse move event (or whatever method
you are using to allow user interaction).

[flexcoders] Re: Question for Math guys/girls

[flexaustin]

Good points.  I guess it would need to be percentage based as I didn't think 
about them shrinking the line past the point, duh. 

Yes the length and angle of the line can change at any time. Also I am not 
placing a marker in the same mc or sprite, but rather a popup on the mainstage 
needs to hover over that point on the line.

You will probably end up using a mixture of the two languages.
The Flex bits will help you get the screen assets together, the look and 
feel of it. This higher level Flex code, written in mxml (like xml), 
enables you to quickly get screen layout organised. This mxml also gives 
you extra services to call on, compared to AS3.

The AS3 bits will add extra code to support what you do with the screen 
assets -boxes, etc. The AS3 code you use in Flash works in the same way 
in Flex, which uses a mixture of the two languages.

Personally, all my projects look like Flash applications, written as 
ActionScript projects in Flex. I prefer Flex for coding. Eventually, I 
may use some Flex code, supported by AS3 to write some different types 
of applications.

You will get more done with Flex but I think you will need AS3 eventually.

I would learn both.
Think of it as two tracks that merge or separate as the needs change.

[flexcoders] Re: Question about event.label

[Tim Hoff]

For Menu controls, if the data provider is an Array of Strings, Flex
uses each String value as the label.  When a menu item is clicked, the
item's label is passed to the ItemClickEvent's label property.  It would
be necessary to use name-value pairs, in the dataProvider, if you used
the Menu's labelField or labelFunction properties.

see a mix of Flash and Flex(mx:) packages. Is that mean that I can use the
Flash packages listed in the Language Reference to develop with Flex 3?
Thanks

 I am learning AS3 with Actionscript 3 Esssential Training(Lynda.com) but I
 was told that the Flash packages are different from Flex 3 packages.
Should
 I continue learning AS3 with this video? It use Flex 3 as compiler but
does

 Flex? I don't want to waste my time. Thanks for your time.

Yes, the AS3 is the same.

But will AS3 that I am learning under Flash CS3 be exactly the same than in
Flex 3? I mean I understand that the packages are sometimes different  have
compatibility issues but what I am trying to say is will be able to apply my
AS3 coding habits into Flex 3?

I want to make the icons visible only if the horizontal scroll is enabled 
(because enough items were put in the horizontal list).
How do I do that?

UIComponents have a visible:Boolean property which you can set to true or false.

You can tell whether a Container is scrollable by checking whether its 
maxHorizontalScrollPosition is greater than 0.

Hi,
   
I am new to Flex. I am looking for help on designing a custom component 
that will
hold a lot of items. When the items exceed the number that are visible 
in the ui
of this horizontal component on the webpage an icon appears, which if 
you click
will show a list of the other components you can click again and 
restore the ui with
that item. Hope you understand what I am talking about. If not please

RE: [flexcoders] Re: Question about a flex component

[Gordon Smith]

The compiler wouldn't have a declaration of 'data', so would assume item.data 
has type *. At runtime it would have type int if its value is 1. But you could 
use class to define data items with strongly typed properties:

public class MyItem
{
public var label:String:
public var data:int;
}

and then the compiler would know that 'data' is int at compile-time.

None of my messages are getting posted on this forum.  The dataProvider is a 
ArrayCollection of cusom objects.  I 
added listeners to each object before I added the object to
the horizontal list at runtime.  I am not sure how to propogate the events when 
an item is selected from the horizontal list.

[flexcoders] Re: Question about a flex component

[veena_kris2003]

I have two problems at this point.  I used the following example,
to modify my code.  But problem 1 is: even though I added an eventListener to 
the object that I added to the HorizontalList, the
eventListener is not getting called when I click on the object in the UI.  
problem 2 is: the horizontal scroll bar looks wierd, it does not look like it 
should.  How should I proceed?

much appreciated,

Veena

That's not how list-based components work. You don't add event listeners to 
data items. You listen to events dispatched by the list itself.

What are you trying to accomplish with your event handlers?

 My message from earlier today never got posted. How do you add event 
 listeners to objects in the horizontalList. I added the event listeners to 
 the objects before I added the objects to the list. The event listener is not 
 getting called.

RE: [flexcoders] Re: Question about a flex component

[Gordon Smith]

The same way you dispatch any other event: Construct the Event instance, set 
its properties, and then call dispatchEvent() on the object that the event 
should be dispatched from (which generally is 'this'):

var mouseEvent:MouseEvent = new MouseEvent(MouseEvent.MOUSE_DOWN);
mouseEvent.localX = 10;
mouseEvent.localY = 10;
...
someComponent.dispatchEvent(mouseEvent);

Do you mind posting an example.   It sounds like this is what I was looking

component that I can click and scroll to more items.

Thanks,

 Suppose there are 100 items and you can only see 10 at a time. So first you 
 see 0-9. When you click the icon you see 10-19. When you click it again you'd 
 see 20-29. So you'd need another icon (previous page instead of next 
 page) to go back to 10-19 and then 0-9.

No, I don't have an example and don't have time to create one for you since I'm 
a development engineer, not a support engineer.  But here is what you should 
try, learning as you go:

1. Create an app with an mx:HorizontalList.
2. Make it show data items by assigning its dataProvider. Put in more data 
items that will fit.
3. Turn off its scrollbar by setting horizontalScrollPolicy=off.
4. Create mx:Buttons for Previous and Next, positioned to the left and 
right of the HorizontalList.
5. In their 'click' handlers, put code like 
horizontalList.horizontalScrollPosition += 1. Use -= for the Previous button.

When I have an HBox component and I dynamically add items, items get added, but 
when I have a HorizontalList and I dynamically add items,
nothing gets added.  The item I am trying to add is a class that extends 
mx.core.UIComponent.

RE: [flexcoders] Re: Question about a flex component

[Gordon Smith]

You add child components which are UIComponents to a container like HBox.

But you add data items to a list-based control like HorizontalList. These data 
items then get displayed by item renderers, which are children which get 
automatically created to display data items. The children are managed by the 
list, not by you... you manage the data, not the renderers.

By default, data items are expected to have a 'label' property to display, 
unless you set the labelField or labelFunction of the list component. They can 
be plain Objects, or  instances of data classes, or anything else, but  
typically they aren't visual components.

Here's an example of adding two data items to a list using ActionScript.

myList.dataProvider = new ArrayCollection();
var item:Object;
item = { label: One, data: 1 };
myList.dataProvider.addItem(item);
item = { label: Two, data: 2 };
myList.dataProvider.addItem(item);

 I get an [Object object] and not the IP address. Any idea's of where I

monitor function will need to be redone. I welcome any pointers and

What if you use something like afterEffects to embed an image on top of the

simply overlay that same image in your player with the reverse blendmode.  They

 Hi,
 
 We're currently using FMS 3.0 as a streaming solution in an effort to prevent 
 people stealing our FLV's, with limited success. The main issue we're running 
 into is people using stream downloading software which is basically creating 
 a new connection to FMS and downloading the stream. My question is - is it 
 possible to intercept the FLV stream coming into a Flex application before it 
 goes into the buffer and edit those bytes? Basically I'm looking at the 
 possibility of encrypting the FLV on the server and then decrypting it on the 
 fly as it streams into the Flex application. Does anyone know if this is 
 feasible or not, or if not, what about the idea of decrypting the data in the 
 buffer prior to it being accessed by the video player? I'm still semi-new to 
 the whole concept of streaming video and FLV playback so if this is a stupid 
 question please be gentle :).

Those tokens are replaced at runtime using the values in the http request url. 
You can also use custom run-time tokens that are replaced using options that 
are passed to the JVM. The following section of the blazeds documentation 
explains this.

I'll try again, shorter version.

 Another approach, if you're set on binding: Rather than the outer
 component waiting for creationComplete on the inner component to set the
 model value, simply put code in the inner component that waits for
 creationcomplete and creates the component-model return bindings
 programmatically via BindingUtils.

Hi Josh.
I didn't give up on bidirectional binding, but I admit to be close to the metal 
:)
The strategy that seems to work is this:
- a value object with two methods: saveOriginal and restoreOriginal, also 
useful to manage the form's cancel button
- binding through BindingUtils into createComplete
- a mono-binding for date fields, because of a bug in DateField.as

Here is some code. In case of interest, I'll post the implementation.
bindForCreate does a single bind, while bindForUpdate does two.

Also, try using commiting event only bindings for the trip back to the
model. I don't use it so I'm not sure, but it might be exactly what you're
looking for.

My View Model system doesn't have these problems (and keeps track of dirty
fields, etc), but it's wordy. I do some code-generation with a combination
of BeanScript voodoo in JEdit and a custom Flex app, which cuts down on the
work. I'm not 100% happy with my pattern yet, and need to write a helper
util to better manage binding events, but it's getting close to good enough
to release to the public :)

Re: [flexcoders] Re: Question from a C developper

[Maciek Sakrejda]

I prefer uint over Number for representing a long.

To clarify, uint is just that: an unsigned 32-bit integer. A long is
(typically) a signed 64-bit integral number. A uint will allow you to
express numbers that are twice as large as the largest int, but that's
only a small fraction of the range of long (and it ignores the negative
range entirely).

A Number, as mentioned before, is an IEEE-754 double (64-bit floating
point number). The problem with representing longs as double is that at
some point, you'll find a long x such that

((Number) x) == ((Number) x + 1)

due to the properties of IEEE-754 floating point (i.e., there simply
aren't enough bits in the representation to distinguish those two). I'm
not sure what that long x is exactly.

So basically, there is no long in ActionScript. You can approximate one
with uint, you can approximate one with Number, or you can write your
own BigInteger class and do the math internally. That's probably going
to be quite ugly and complicated, especially since you can't use
operator overloading for basic arithmetic.

That's correct.  My use of uint is not a perfect replacement for long and is 
based on assumptions made for a specific project.  I should have been more 
clear about that.

ActionScript does not support long for portability purposes.

The ServiceLocator is a singleton as you probably already know, and if

RE: [flexcoders] Re: Question about HTTPService and callbacks

[Tracy Spratt]

I see a few ways to do this.  The key to all of them is using
AsyncToken.  

 

You could add a callback parameter to your components send() function.
If you use a function, then you can place a callback function directly
in the AsyncToken(Responder?) and have the result handler execute the
function

 

You could use a string that is the name of the callback function, put
that in the AsyncToken, and in the handler, like you have done, use
bracket notation to get a reference to and execute the function.

 

You could pass in a string use a string that identifies the call, then
have your component dispatch an event on result.  Either use a custom
event that contains the result data and call identifier, or expose the
lastResult and callId in public properties.  Have the handler for
the components result event use that data to execute whatever you need.

 

You can mix and match these approaches as well.

 

Tracy

I can't quite follow how your application is put together. Usually the view 
is bound to the model via the modellocator and I don't really see the 
problem with that. I'm not sure what you are doing with the constants in the 
modellocator. The model shouldn't be tracking what is happening in the view.

Basically the view issues events to notify the model of what changes are 
happening and to cue the model to make changes to itself as a result of what 
is going on in the view. The model changes and via binding the view is 
updated.

[flexcoders] Re: Question about Best Practices for Applications with many views using Cairngorm

[Justin J. Moses]

OK, I see what you're saying. I'm actually fairly new to Cairngorm, so
I'd be interested in what others have to say about this...

Personally, in my app, I assigned modules to user roles, and used the
class name of each module as the name of the that contains it. This
seems like it might still be coupling the view and model too tightly,
though I'm not certain.

Anyone? 

[flexcoders] Re: Question about Best Practices for Applications with many views using Cairngorm

[Justin J. Moses]

Paul,

 If you're trying to understand Cairngorm by reading the docs and
going through the Cairngorm Store demo, you'll notice that the views
are toggled via constants in the model:

eg.


if( model.workflowState ==
ShopModelLocator.VIEWING_PRODUCTS_IN_THUMBNAILS )

... 


so the various views or different features/sections that the user sees
in the store are: 

ShopModelLocator.VIEWING_PRODUCTS_IN_THUMBNAILS
ShopModelLocator.VIEWING_PRODUCTS_IN_GRID
ShopModelLocator.VIEWING_CHECKOUT 


So that would explain why both the original poster and myself, would
assume that for various features in your own app - such as a My
Profile, Inbox, Contacts for an email application for example -
would have to be handled by a viewstack and a list of constants. 

Do you think the Cairngorm Store app has been written with inherent
flaws? If so, then how would you rewrite it to illustrate the
behaviour you mentioned before? 

cheers,
Justin 

Re: [flexcoders] Re: Question about Best Practices for Applications with many views using Cairngorm

[Paul Andrews]

First of all, I'm no Cairngorm expert and I'm not going to criticise a 
reference implementation.

For a store application (any store) I would consider that the model would 
hold details of the stock items and the baskets of any shoppers. I wouldn't 
have the model keep track of what the shopper is currently doing, because 
that's not something that affects the shop stock or the users basket. The 
view on the other hand is concerned with what the user is doing and needs to 
keep track of the view state in order to manage the interface.

In this respect I would be using constants to represent view states but they 
would be constants associated with view classes not model classes.

My feeling is that model classes need to be as far as possible separate from 
the view, so that in theory you could replace the view implementation 
without changing the model at all.

Inevitably there is a coupling between view and model but it's in terms of 
how the model is manipulated and accessed by the view.

That's how I think about these things. I've been wrong before and will be 
again and I have no criticism for the Cairngorm Store.

I'm not sure that's helpful.

Paul

[flexcoders] Re: Question about Best Practices for Applications with many views using Cairngorm

[Justin J. Moses]

I think that's a fair point you've made and I can't understand why the
constants are in the model either in the Cairngorm Store. 

Seems to me like there should be a Singleton related to the view
holding the list of available views to switch between. But I'm no
Cairngorm expert either :P

Re: [flexcoders] Re: Question about Best Practices for Applications with many views using Cairngorm

[Douglas Knudsen]

personally, I leave States to component level 'dynamic Flexi-magik' and use
Viewstacks for major view changes.  Viewstacks just seem more appropriate
for major view changes.  States I leave to component changes, eg a edit vs
view in a form or something like that.  IIRC, States actually are more
complicated in implementation too, in case that matters.  I just think the
intent of States was not application state, rather component state.

Don't know why it doesn't fail in that case, but it could be timing of
some sort.  The exception you got may always be from Module1 or 2 so
then it would work depending on the order of loading.

It is essentailly the same problem.  Each module has a definition but

  TypeError: Error #1034: Type Coercion failed: cannot convert
  com.gh.vo::[EMAIL PROTECTED] to com.gh.vo.DataVO.
  
  However, I can only get the compiler to throw this error in 1
 situation:
  
  I start the app, load Module 2, than Module 1, than go back to
Module
  2. After I arrive back at Module 2, it throws the error on the
  resultHandler of the RemoveObject service, in code that looks like
 this:
  
  private function resultHandler( event:ResultEvent ):void {
  var hash:Array = new Array();
  for each( var data:DataVO in event.result ){
  hash.push(data);
  }
  dataAC = new ArrayCollection( hash );
  }
  
  It breaks on the for each() line.
  Any ideas?

What does This is a test mean?

 

TextArea doesn't display data, it displays text. It uses TextField, a
Flash Player class, to display that text, and TextField cannot display
text from bottom to top.

 

If your text consists of short non-wrapped lines ending with \n, then
using String.split() to split your text into lines, Array.reverse() to
reverse the lines, and String.join() to reassemble them in the opposite
order.

Split the string into an Array,and reverse it.  But I bet that is not
really what you want.  What do you want?

[flexcoders] Re: Question about Changewatch?

[haykelbj]

Did you declare the variable theChange as Bindable?

This works for me:

?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
layout=absolute creationComplete=init()
 mx:Script
 ![CDATA[
 import mx.controls.Alert;
 import mx.binding.utils.BindingUtils;

 [Bindable]
 public var theChange:Boolean;

 private function init():void
 {
 BindingUtils.bindProperty(this,onChange, this,
theChange );
 }

 public function set onChange(value:Boolean):void
 {
 Alert.show(change happen);
 }

 private function finishit():void
 {
 theChange = true;
 theChange = false;
 }
 ]]
 /mx:Script
 mx:Button x=105 y=359 label=save click=finishit()/
/mx:Application

 Hi,

 I did a simple test for changewatch.I try to watch a variable
 change.but I am not sure why it doesn't work.

 (variable theChange change from true to false)

 The code is here:

  BindingUtils.bindProperty(this,onChange, this, theChange
);

  }

   public function  set onChange (value:Boolean):void
  {
  Alert.show (change happen);
  }



   private function finishit():void{
