Re: [flexcoders]How do I get the key of an Object?
If you're trying to compare one object to... the "same object", you can use the strict equality operator (===) http://www.adobe.com/support/flash/action_scripts/actionscript_dictionary/actionscript_dictionary044.html "Variables, objects, arrays, and functions are compared by reference. Two variables are equal if they refer to the same object, array, or function. Two separate arrays are never considered equal, even if they have the same number of elements."

Re: [flexcoders]Need help creating a Singleton with MXML
Yay! That's the class I needed! :) To answer your question why. First I like to use MXML. Any tool can parse XML. Plus, with this class, I plan to drop it into all my future project and set properties on it. If I had more than one instance it would screw up the application. Other classes use some of its functionality so I am providing a getInstance(). The problem has been that the other classes may be declared before the MXML instance. So I updated my code to always call the getInstance() method and both problems have been solved!!!

Re: [flexcoders]How do I get the key of an Object?
Graduate from hogwarts. I was thinking of comparing it to another object to see if I had a match. I suppose I could evaluate if (this=objectiamlookingfor). The problem is the object is on the application and the object extends EventDispatcher. If it extended DisplayObject I could enumerate all the instances on the application and do the comparison. Since it extends the EventDispatcher it isn't in the enumeration list of the application.

Re: [flexcoders] DataGrid selectAll problem
I started with the example from your blog dated Feb 2008 (CheckBoxListAndDataGrid). To deselect the other rows, the checkbox column header renderer calls a 'selectAll()' method on the CheckBoxDataGrid with a flag of false. That method builds two arrays - one for all items in the collection and one for all indices in the collection. It then replaces mx:DataGrid.selectedItems and selectedIndices with new arrays. In the deselect case, the new arrays are empty. In the select all case then have all items/indices. Visually, selectAll true/false seems to work when it's called. But in the use-case I describe below I'm counting on the mx:DataGrid.selectItem() to be called in order to deselect rows in the case that a single row is selected. Based on trace statements, I know that mx:DataGrid.selectItem() is never called when the problem occurs Is there something about the way I'm selecting things which causes the selectItem() to not be called? I tried replacing just selectedItemds or just selectedIndicies or both. it doesn't seem. Thanks, Glenn On Fri, Jan 9, 2009 at 1:11 AM, Alex Harui wrote: >Which example did you start with?

[flexcoders] Flash Remoting Options
Hi, all; I built a great little example file using AMFPHP. It works great on my local installation of WampServer, but when I uploaded it to my web host, the Service Browser for AMFPHP wouldn't work. I contacted my host, and they said that was because my hosting is Windows (which I did on purpose so I could play with ASP). They use ASAPI or CGI to handle the PHP part. I don't want to change to a Linux account just over this one example file. Are there remoting options that can work on my existing hosting plan? Thanks; Amy

[flexcoders] Error: Access of undefined property
Hello,
It just kinda weird that i encounter and here is the cscenario:
I create a StringUtils.as;
package com.buspinoy.utils
{
public class StringUtils
{
public static function isEmpty(str:String):Boolean
{
return str == null || str.length == 0;
}
public static function isNotEmpty(str:String):Boolean
{
return !StringUtils.isEmpty(str);
}
public function StringUtils()
{
}
}
}
...this is based on org.apache.commons.lang, but when i put in a code like
this:
if (StringUtils.isEmpty(selectedText) )
{
comboCursor.findFirst(selectedText);
this.selectedItem = comboCursor.current;
}
...it gives me error Access of undefined property...any idea what is
happening?because i have static function working properly but not inside the
"if" condition.
btw, quick question, does AS will support method overloading in the future?
Thanks a lot.
Cheers.

Claudiu From: lampei To: flexcoders@yahoogroups.com Sent: Saturday, January 10, 2009 1:34:25 AM Subject: [flexcoders] Cairngorm and ChangeWatcher I have begun tinkering around with various frameworks and thought I would start with Cairngorm. I am refactoring a small application to use Cairngorm, but ran into a snag. All of the examples I found just bound an item in the view to a property of the ModelLocator, and thus automagically updated the value when the property of the ModelLocator changed. However, I had one item that is waiting for a response from a service, and needed to respond to that change (such as an error message), rather than just display the updated data that is returned. I found an example that uses the ChangeWatcher class to watch the property on the ModelLocator. This seemed to work fine, but I was wondering if this is still best practice, as the example I found was from 2006. Thanks.
