Re: [flexcoders] Re: binding not updating for ArrayCollection when item changes?
Thanks Josh! I haven't tried to implement this yet but so far it makes
sense.
Thanks again,

Yeah, I've been directly updating the properties. Here's the weird
part... if I use the ArrayCollection as a dataProvider for a List
control, it updates. If I use it for a custom control that I've
created, it does not.
Example:
This works as expected:
mx:List dataProvider={model.users}/
This does not:
jr:customComponent dataProvider={model.users}/
//pseudo component source
customComponent
mx:Script
private var _dp:ArrayCollection;
public function set dataProvider(dp:ArrayCollection):void {
_dp = dp;
trace(this fires when the AC is created, but not when it's
contents change);
}
/mx:Script
/customComponent
Thanks again!

Re: [flexcoders] Re: binding not updating for ArrayCollection when item changes?
In your custom control, change this:
public function set dataProvider(dp:ArrayCollection):void {
_dp = dp;
trace(this fires when the AC is created, but not when it's contents
change);
}
to something like this:
public function set dataProvider(value : ArrayCollection) : void
{
if (_dp == value)
return;
if (dataProvider)
dataProvider.removeEventListener(CollectionEvent.COLLECTION_CHANGE,
handleUpdatedProvider);
_dp = value;
if (dataProvider)
dataProvider.addEventListener(CollectionEvent.COLLECTION_CHANGE,
handleUpdatedProvider, ???, ???, true); // Weak listener!
handleUpdatedProvider(null);
}
private function handleUpdatedProvider(event : CollectionEvent) : void

[flexcoders] Re: binding not updating for ArrayCollection when item changes?
I don't know if this is your problem but one thing I noticed is youu have an
ambiguous set of your enabled property. You have
enabled = enabled;
which (I assume) is to set the enabled property of your class to the enabled
parameter that is passed in. This won't work. You should have
this.enabled = enabled;
or change one of the parameter names.

Nice catch! That didn't seem to be causing the problem but thanks for

I've simplified the case in that I'm not calling the web service

[flexcoders] Re: binding not updating for ArrayCollection when item changes?
Hi John,
I seem to remember that XMLList, like Array, isn't Bindable and doesn't
dispatch a propertyChange event. You might try changing the public var
to a getter/setter and manually dispatching the event, or change the
XMLList to Object; to see if it makes a difference. This is just a shot
in the dark, but let us know if it helps.

[flexcoders] Re: binding not updating for ArrayCollection when item changes?
How do you update a given UserVO's userData? Do you directly access the
public properties?
I have never done it this way - I use getters and setters...
package com.jrobinson.model.VO
{
[Bindable]
public class UserVO
{
private var _id:int = -1;
private var _username:String = null;
private var _enabled:Boolean = false;
private var _userData:XMLList = null;
public function UserVO(id:int, username:String, enabled:Boolean,
userData:XMLList)
{
_id = id;
_username = username;
_enabled = enabled;
_userData = userData;
}
//accessor methods
public function get id():int {return _id;}
public function get username():String {return _username;}
public function get enabled():Boolean {return _enabled;}
public function get userData():XMLList {return _userData;}
//mutator methods
public function set id(id:int):void {_id = id;}
public function set username(username:String):void {_username =
username;}
public function set enabled(enabled:Boolean):void {_enabled =
enabled;}
public function set userData(userData:XMLList):void {_userData =
userData;}
}
}

Nice catch! That didn't seem to be causing the problem but thanks for
pointing it out.
I've simplified the case in that I'm not calling the web service
anymore, just flipping the enabled property but binding still is not
updating. Any other ideas?
Thanks,
John

I don't know if this is your problem but one thing I noticed is youu
have an ambiguous set of your enabled property. You have
enabled = enabled;
which (I assume) is to set the enabled property of your class to the
enabled parameter that is passed in. This won't work. You should
have
this.enabled = enabled;
or change one of the parameter names.

I have a strange issue with data binding not updating when an item
in
an ArrayCollection is changed. I'm using Cairngorm and have the
following setup. In my ModelLocator I have a 'users'
ArrayCollection
that contains 'UserVO' objects. I have a two views that binds their
dataProvider to the 'users' AC in the ModelLocator. My UserVO looks
like so:
package com.jrobinson.model.VO
{
[Bindable]
public class UserVO
{
public var id:int = -1;
public var username:String = null;
public var enabled:Boolean = false;
public var userData:XMLList = null;
public function UserVO(user_id:int, uName:String,
enabled:Boolean,
d:XMLList)
{
id = user_id;
username = uName;
enabled = enabled;
userData = d;
}
}
}
I first have a command that loads all of the users and populates
the
AC. This updates the bindings as expected. I then have a second
command that loads the userData portion for a given user. Once
retrieved, I update the given UserVO's userData, but this time, the
bindings fail to update.
I feel like I've seen this before but can't find where or what the
workaround might be. I guess I'm just looking for confirmation that
this should or shouldn't work.
Thanks!
John
