Re: [flexcoders] Re: speed of the for each looping
Sometimes it makes sense to compare the total effect of one approach to another... like comparing your favorite cereal to a competing product. Nothing speaks better than hard and fast facts like... It would take over two and a half million bowls of your oat bran cereal to equal the fiber content of one bowl of Super Colon Blow. Yes...

Re: [flexcoders] how do you blur smoothly between two states?
just dug into the AS3 classes and it by default fromX/fromY has a default
value of 4 and in the BlurInstanceClass it doesn't save the current blurX/BlurY
values. I could create an event that listens for the update, the only time the
value are sent, but then that adds extra overhead for each update.
Instead what I'll do is call a function to iterate the filters list, grab
blurX/blurY.
Just wished they would have exposed a blurX and blurY prop on the Blur the
wiring is there, just failed to provide a stub.

hrmm, I don't get it
Say I have this on rollover:
mx:Blur id=blur duration=1000 blurXTo=10 blurYTo=10 blurXFrom=0
blurYFrom=0 target={this} /
and this on roll out:
mx:Blur id=unblur duration=1000 blurXTo=0 blurYTo=0 blurXFrom=10
blurYFrom=10 target={this} /
works, cool, rock on. however if I mouse off at say 500ms the blur JUMPs to the

I've tried ommiting blurfrom or setting the value to *, and even
blurXFrom={ blur.blurXFrom} blurYFrom={ blur.blurYFrom} but no dice.
what gives?
Re: [flexcoders] Getting NULL Object Reference while deleting last element of the list
Anuj,
I think there is something wrong with this structure. Why make it into for loop?
The _addToAssociatedDevicesArr is received the same value
for(var i:*=0;i_addDevicesLen-1;i++)
{
_addToAssociatedDevicesArr=nvrsInPoolList.selectedItems;
}
The last loop has the same problem. The index variable t is never used.
Why it is in for loop?
for(var t:*=0;t_addToAssociatedDevicesArr.length;t++)
{
if(nvrsInPoolList!=null)
{
IList(nvrsInPoolList.dataProvider).removeItemAt(nvrsInPoolList.selectedIndex);
}
}
About the problem you complain
I think one of this variable is null value:
camerasInPoolList
arrAddToPool
arrRemoveFromPool

Re: [flexcoders] how do you blur smoothly between two states?
I know I'm answering my own questions but hope someone has gone down the same
path as me, can tell if I'm overlooking something obvious or wants to learn
from my mistakes. . .
My previous idea didn't work thanks to
transitionblurBlurInstanceTweenInstanceTween.endTween.
endTween sets the tween to whatever state it should be at in the final
position. In this case whatever blurXTo and blurYTo is.
to work around I'm listening for an update event and reset the blur to the last
known value after it gets set to the end value on effectEnd. HOWEVER, this
causes a noticable flicker as the endTween state is briefly displayed because
BlurInstance.onTweenEnd.calls the private setBlurMethod.
so it now seems that i need to override the endTween method in my own class to
prevent the tween from setting its to values. Unless of course I'm missing
something painfully simple.

RE: [flexcoders] Re: flex login popup help needed pleaseeeeeeeee
Your next steps:
* Create a simple php page that takes an http request, reads the
UserId and Password request parameters. Allow for either form(POST) or
querystring(GET) parameters. Keep the authorization logic simple to
start with, by hardcoding a userid and password to match. Have the php
page return an xml response, something like: loginresponse
status=success / Make status=fail if the user/pwd do not match.
Test this page in a browser.
* Declare an HTTPService tag in your main app. Set
resultFormat=e4x. Declare result and fault handlers. Set the url to
the tested php page above
* Define a tryLogin function that takes user and password as
arguments. In that function, build a request object with userId and
password properties and assign the values passed into the function.
Invoke send on the HTTPService.
* When user clicks the login button, call the tryLogin function,
passin in the values entered by the user.
* In the result handler, read the event.result as XML, and look at
the @status. If success, set the ViewStack.selectedIndex to show the
Admin view

Good question. What did you do with all the old eventListeners
you

My current implementation has something like:
function save(xml:XML, successFunc:Function,
failureFunc:Function):void {
var service:HTTPService = new HTTPService();
...
service.addEventListener(ResultEvent.RESULT,
function(evt:ResultEvent):void {
trace(Successfully saved XML);
successFunc();
});
service.send(); // called after the event listeners have been
added :)
}
That's it. The successFunc and failureFunc are only scoped to the
calling
code's method and so should be garbage collected when the service
is garbage
collected.
What I don't know is when the service is garbage collected? I'm
assuming not
before the result or fault event is fired!
My understanding is that anonymous functions _cannot_ get garbage
collected unless you use weak references when you add them. Which
means there's a really good chance they'll get garbage collected
before they get called.

Re: [flexcoders] Best practice for calling asynchronous functions?
So are you saying that, in general, anonymous functions should not be used as listeners? If its anything like in Java, (once the calling method returned) the anonymous function would only be referenced by the event dispatcher and so (assuming weak references are not used) would only be garbage collected when the event dispatcher is garbage collected. At least, that's how I understand it. I posted a question about this a few weeks ago, but didn't get a reply.

[flexcoders] Binding Question - ArrayCollection/ResourceBundle
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?

[flexcoders] Restrictions on non-visual component placement
*Short version:* I have a non-visual component that I'm trying to declare in a repeater, but it seems that MXML doesn't allow this. Is this true? How do you get around this, create a visual component to wrap the non-visual component? *Long version:* I have an ActionScript non-visual component whose declaration looks like this: public class DetailPopup extends EventDispatcher implements IMXMLObject I've used this successfully inside an inline, MXML item renderer, like this: mx:DataGridColumn mx:itemRenderer mx:Component mx:VBox !-- a bunch of other stuff, and then my: -- my:DetailPopUp/ mx:VBox /mx:Component /mx:itemRenderer /mx:DataGridColumn Now that I'm switching from a DataGrid to a Grid, the code ought to look like this: mx:GridItem mx:VBox !-- a bunch of other stuff, and then my: -- (X) my:DetailPopUp/ mx:VBox /mx:GridItem ..except that I'm getting an error, Component declarations are not allowed here. (Note: visual children must implement IUIComponent.) After trying out a bunch of scenarios, it looks like non-visual components can only be declared in the outermost scope of a component or application. Is this true? This is rather awkward, as I need a DetailPopUp for each griditem. Any tips would be very helpful! Michael
[flexcoders] Re: AS ResourceBundle Keys with Args?
Let me clarify. I am trying to use argument placeholders in my
ActionScript created Resource Bundle.
In a .properties file, you would write:
DISTANCE_FORMAT={0} miles
So how would you do the same in ActionScript? The compiler does not like
the curly braces {}?
rb.content[DISTANCE_FORMAT] = {0} miles; //?? does not like {0}

RE: [flexcoders] Best practice for calling asynchronous functions?
I think Amy's point is that, w/o a reference to the anonfun, you can't call
removeEventListener on it. If I do:
someObj.addEventListener(foo, function (e:Event) { ... } );
someObj will release the anonfun when it gets garbage collected. However,
until that time, all objects in the scope chain won't be collectable. I don't
know if that's the case in Java.

If its anything like in Java, (once the calling method returned) the
anonymous function would only be referenced by the event dispatcher and so
(assuming weak references are not used) would only be garbage collected when
the event dispatcher is garbage collected. At least, that's how I understand

Re: [flexcoders] Restrictions on non-visual component placement
I think that might be a distraction, I was asking a question about the rules
of MXML, rather than asking for debugging help for my non-visual component.
But just for fun, I'll explain! I was looking for a way to reuse the nice
way that PopUpButton manages its pop-up, so I created a non-visual component
that you could use to orchestrate popping up on rollover or on focus.
mx:Label id=info text=Roll over me for more information/
mx:VBox id=moreInfo includeInLayout=false visible=false
mx:Label text=Hi, I'm more information! /
/mx:Vbox
my:DetailPopup target={info} popUp={moreInfo}/
This works really well, and we use it in a few places so we can use ad hoc
detail pop-ups. We've even used it inside a datagrid item renderer:
mx:DataGridColumn
mx:itemRenderermx:Component
mx:Label id=info text=Roll over me for more information/
mx:VBox id=moreInfo includeInLayout=false visible=false
mx:Label text=Hi, I'm more information! /
/mx:Vbox
my:DetailPopup target={info} popUp={moreInfo}/
/mx:Component/mx:itemRenderer
/mx:DataGridColumn
When we switched to a grid with a repeater, I discovered the prohibition on
nonvisual components that weren't parent of the root tag.
mx:GridItem
mx:Label id=info text=Roll over me for more information/
mx:VBox id=moreInfo includeInLayout=false visible=false
mx:Label text=Hi, I'm more information! /
/mx:Vbox
(x) my:DetailPopup target={info} popUp={moreInfo}/
/mx:GridItem
So the solution appears to be to take the guts and put it in its own
component definition, and then do this:
mx:GridItem
my:WholeChunkaStuff/
/mx:GridItem

[flexcoders] Re: Best Practices: ArrayCollection of custom objects?
Is this such a trivial question that people are passing up replying
in lieu of bringing light to my ignorance, or are there really no best
practices to speak of here?
The only way I've found so far to do this is to deprecate the
overridden method, but even then from time to time we'll get a strange
error (this doesn't happen all of the time):
1021: Duplicate function definition.
Seems pretty obvious what's causing it, but we have other classes that
use this same syntax that aren't generating the error...
Is there any reason we shouldn't do this, or is there another, more
acceptable way to accomplish what we're trying to do here?
public class DataTypes extends ArrayCollection
{
public function DataTypes(){
}
[Deprecated]
override public function addItem(item:Object):void{
}
public function addItem(item:DataType):void{
super.addItem(item);
}
}
Re: [flexcoders] Restrictions on non-visual component placement
It still seems to be true. Yes, I can see that before repeaters are involved, but the detail popup creates a relationship between a pair of components - so once I get to an array of such pairs, it seemed like I'd need a detail popup for each pair. It's stateful, and it would get muddled up if one detail popup was trying to coordinate multiple pairs of controls. (Basically, I wanted the repeater to manage instances of the detail popup as well.)

Yes, that's what I meant. I guess it depends on how you're setting
up someObj as to whether someObj would be eligible for garbage
collection itself. But the event listeners can't be released
independently, except if the thing Ralf suggested works (interesting
suggestion, Ralf...I use arguments.callee for other things sometimes
myself...never thought of using it that was).
Honestly, the reason I don't use anonymous functions is that they

RE: [flexcoders] Binding Question - ArrayCollection/ResourceBundle
You are defining dynamic objects and they are not bindable. If you had a class
that dispatched an event when the locale changed then it should work.

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?

RE: [flexcoders] Re: Best Practices: ArrayCollection of custom objects?
There's no way to make a function parameter more narrow in an override, or
have multiple signatures for functions, so there's no way to catch this at
compile time. You can hint the MXML compiler, but not AS, and usually you
stuff your AC from AS.
The only thing we do is throw an error at runtime. I suppose you could wrap
the whole thing, or copy the code and change signatures.

Is this such a trivial question that people are passing up replying
in lieu of bringing light to my ignorance, or are there really no best
practices to speak of here?
The only way I've found so far to do this is to deprecate the
overridden method, but even then from time to time we'll get a strange
error (this doesn't happen all of the time):
1021: Duplicate function definition.
Seems pretty obvious what's causing it, but we have other classes that
use this same syntax that aren't generating the error...
Is there any reason we shouldn't do this, or is there another, more
acceptable way to accomplish what we're trying to do here?
public class DataTypes extends ArrayCollection

public function DataTypes(){

override public function addItem(item:Object):void{

public function addItem(item:DataType):void{

To make things cleaner I removed all the AS3 code from the Application MXML file and placed it in an AS3 class that extends Application (BaseApp.as). I then updated the MXML file to have base:BaseApp xmlns:base=* as the root tag with dimension still at 300x500. Now I find that the scale mode is not preserved correctly when modifying the dimensions of the embed tag. The UI content in the MXML scales down way farther that the embed dimensions. If I sized the embed tag at 150x250 I see the flash content takes up those dimensions but the visual content provided by the MXML subclass is scaled down to 90x120 . If I move the dimensions from the MXML subclass to the base class then the content is scaled even further to like 45x75 Can anyone help me understand what is going on and how I can make the content scale correctly?

RE: [flexcoders] Re: speed of the for each looping
In section 12.6.4, The for-in statement, of the ECMA-262 spec, it says The mechanics of enumerating the properties (step 5 in the first algorithm, step 6 in the second) is implementation dependent. I don't see anything in the spec about Array being an exception and having a guaranteed for-in order.

[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.
