[flexcoders] Re: Binding question
Weird, I had to use the event=albumToggledEvent for the includedAlbums
getter property and do project-clean.
Spent a whole lot of time on this. So I guess the lesson learned here
is when you think you've got your bindings set up correctly and they
still don't work, project-clean.

I am trying to bind the checkbox selected property as written below.
The value of selected should be triggered whenever currentPresentation
changes or whenever albumIncluded(data) returns a different value.
The
checkbox is in a List itemRenderer component.
ItemRenderer
mx:CheckBox id=albumEnabled
selected={presentations.currentPresentation.albumIncluded(data as
Album)} /
mx:Script
![CDATA[
[Bindable]
private var presentations:PresentationCollection =
PresentationCollection.getInstance();
]]
/mx:Script
The albumIncluded function is in a class called Media and is coded as
follows:
Media class (the class is marked [Bindable])
-
private var _includedAlbums:ArrayCollection /* of Albums */ =new
ArrayCollection();
public function includeAlbum(album:Album):void {
_includedAlbums.addItem(album);
if (!currentAlbum)
currentAlbum = album;
dispatchEvent(new Event(albumToggledEvent));
}
[Bindable(event=albumToggledEvent)]
public function albumIncluded(album:Album):Boolean {
return _includedAlbums.getItemIndex(album) = 0;
}
Apparently the albumIncluded function doesn't fire when includeAlbum()
function is called.
So I put a read-only property called includedAlbums in Media which is
supposed to be triggered when _includedAlbums changes.
Media class (class is Bindable)
private var _includedAlbums:ArrayCollection /* of Albums */ =new
ArrayCollection();
public function includeAlbum(album:Album):void {
_includedAlbums.addItem(album);
if (!currentAlbum)
currentAlbum = album;
dispatchEvent(new Event(albumToggledEvent));
}
[Bindable(event=albumToggledEvent)]
public function albumIncluded(album:Album):Boolean {
return _includedAlbums.getItemIndex(album) = 0;
}
[Bindable(event=none)] // handles runtime binding warnings
public function get includedAlbums():ArrayCollection /* of Albums */ {
return _includedAlbums;
}
And added a helper function to the ItemRenderer component, with the
idea
that if either currentPresentation or includedAlbums changed it would
fire the helper function which would return the correct value for the
checkbox selected property.
ItemRenderer
---
mx:CheckBox id=albumEnabled
selected={albumToggleHelper(presentations.currentPresentation.includedA\
\
lbums)} /
mx:Script
![CDATA[
[Bindable]
private var presentations:PresentationCollection =
PresentationCollection.getInstance();
private function albumToggleHelper(includedAlbums:ArrayCollection /*
of
Albums */):Boolean {
return presentations.currentPresentation.albumIncluded(data as Album);
}
]]
/mx:Script
But it looks like the includedAlbums property is never firing an
event.
How do I get my checkbox selected to set to the right value?
(Note: I also tried setting the bindable event tag to
event=albumToggledEvent for the includedAlbums getter property, and
it
still didn't work.)

[flexcoders] Re: Binding Question - ArrayCollection/ResourceBundle
Thanks, Alex.
So I assume a flex button listens for the locale change event and
therefore updates it's label?
Are you saying create say a LocaleArrayCollection class that dispatches
the locale change event?
Or are you saying create LocaleChangeDispatcher that dispatches the
locale change event and the ArrayCollection would then update by virtue
of the dispatched event?
Thanks in advance.

You are defining dynamic objects and they are not bindable. If you

Is it possible to have an ArrayCollection value updated by a resource
bundle value.
[Bindable]
public var cbDP:ArrayCollection = new ArrayCollection();
cbDP.addItem(
{label:ResourceManager.getInstance().getString('myResources','NAME') });
When changing locales at runtime, all label fields of flex components
update but the ArrayCollection does not.
Is the ResourceManager binding ignored on AC's? Is there another
solution?
Thanks,
Jeff
[flexcoders] Re: binding question?
I guess it's needing [Bindable] somewhere in your code..

b) I show the value in screen 2 with binding (for instance
mx:Label

it works fine when it excute first time.(from screen 1 to screen 2)
Afater I change from screen 2 to screen 1,the binding value
{obj.value} in screen 2 keep the previous value even if I change
the object values in screen 1 (for instance obj.value =xyz).
but the binding value {obj.value} should change to xyz,do you

why this happen.
Thanks for your help.

Thanks for your help. I do not know why I thought updating a text
field would automatically update the VO object. Your help is greatly
appreciated. One more quick question about this, what is the best
practice, to add the text fields to the value object when the form is
submitted (button clicked) or to set up individual functions once each
text field is changed?? I presented just a small portion of my form,
in actuality I have about 35 fields that will contain user information
This is really strange. I have pretty much exactly the same as you,
where I have a ContactDetails object that has a firstName property that
is bound to a textInput field's text property, and when I type into the
field, it sets exactly as intended. My class structure is that
ContactDetails has a constructor that inits all the properties. The
firstName property has both a getter and setter, and it is of a data
type that is also a custom class, DataItem. DataItem has a constructor
that sets it up with default values, and each property has a getter and
setter.
Here are my classes in case you find them useful:
package com.magnoliamultimedia.vo

ln:String='', c:String='', e:String='', p:String='', aff:String='',

true, 'EMailValidator');
_phone=new DataItem(p, 7, 50);
_aff=new DataItem(aff, 0, 50);
_more=new DataItem(m, 0, 255);
}
public function get firstName():*{
return _fn;

public function set firstName(s:*):void{

[flexcoders] Re: Binding question
I tried something similar a while back as a quick and dirty way to change the web service between development and deployment, but could not get it to work. I ended up creating a named service in the flex-config.xml and refer to that, so I only have to set up the service once and depending if my app was in dev, test, or production it would hit the correct internal service (also in dev, test, or production). --- In flexcoders@yahoogroups.com, pilby1 [EMAIL PROTECTED] wrote: How can I then make my wsdl attribute in my mx:WebService a variable?
