If 'arr' were a static var, doSomething() should set it to null before
returning if you want to make the Array object eligible for garbage
collection. Otherwise the static var, which always exists, would
continue to point to it and prevent the Array object from being GCd.

Subject: [flexcoders] Error 1189: Attempt to delete the fixed
property.
hello,
I'm having some very confusing problems with memory leaks. in one
particular function, I dynamically create a new Array(), and when i
try to delete it I get a compile time error. a simplified version of
the function looks like:
public static function doSomething():void {
var arr:Array = new Array();
//do somestuff with the array
delete(arr);
}
When compiling I get the error:
Error 1189: Attempt to delete the fixed property arr. Only
dynamically defined properties can be deleted.
The array isn't added dynamically - it's declared so you may not
delete it.
The storage allocated for the array will be eligible for garbage
collection
(provided nothing else is referencing the array) when you leave the
function - it's no longer in scope.
In other circumatsnces, you can make the array eligible for garbage
collection by setting arr to null (provided nothing else is
referencing the
array).
Paul
In a different situation, I also get similar problems. For example,
when I have a private property that is part of my Application class
i
assign dynamic data to it during the life of the app, but i cannot
delete it.

[flexcoders] Generic itemRenderer for Canvas based controls
I have a TileList control that I want to populate at runtime with a
collection of custom controls determined by preferences held on the
user which I retrieve after they log in. All of the custom controls
are based on Canvas.
My current approach is to have an Array into which I push the
appropriate controls after login success and bind that array as the
dataProvider on my TileList control. The trouble is that the controls
don't get rendered because there is no itemRenderer defined for the
TileList.
So I attempted to create a generic itemRenderer based on Canvas which
overrides the set data() method and adds the inbound control as a child...
override public function set data(value:Object):void
{
if (value == null) return;
var cvs:Canvas = value as Canvas;
this.addChild(cvs);
}
However, this throws index out of bounds errors doing a getChild(0)
deep in the bowels of the framework code associated with the dynamic
itemRenderer component, which I don't seem to be able to overcome in
spite of altering the sequence in which things get created, and
fiddling around with the creationPolicy of the custom controls.
So I'm a bit stuck and wondering whether there is a different approach
or I'm just doing something wrong.
Any ideas?
[flexcoders] Re: Flex and Java Communication
--- In flexcoders@yahoogroups.com, saritha [EMAIL PROTECTED] wrote: Hi, How to communicate between Flex and Java? There are two main ways and which you choose depends largely on the future needs of your clients. If you need a generic API on your server because you are going to implement a variety of clients, or you want to open up your application for other people to code against, then a web service on the Java end and HTTPService in your Flex code is definitely the way to go. However, if you are looking for speed and small packet size and squeezing the most out of your app, then you should use AMF via RPC, i.e. remote objects and BlazeDS. You'll have a tight binding between your types on both sides and the API can be very clean and tailored specifically to your needs. I find it more elegant and there's less code to maintain. I have used both but prefer the remote object approach as I think that coding for possible future scenarios tends to unnecessarily dilute my current app and I'd prefer to take the performance advantages of AMF. It's a trade-off I am happy to make and you need to make the same judgement.

I also looked at Alex's code and decided I wanted something a little more suited to my peculiar needs. I implemented a custom control which has two data grids, one for the data and one for the totals at the bottom. I also added some fancy code to cope with making totals in different ways (e.g. aggregating averages - the old sum(x)/n vs sum(x/n) problem) and to handle formatting. It is not as clean an interface as I would like, but it is pretty useful and it now appears in lots of places in my UI. There is a known bug where the column widths are misaligned when trhe control first shows, but my users seems to be able to live with that.

borderStyle: errorTipAbove;
paddingBottom: 4;

paddingTop: 4;
}
If I un-comment fontSize, the font gets bigger but the tooltip text
gets outside of the tooltips 'area'. Ie text length is 200 pixels and
tooltips area 150 pixels... Is the tooltip's area calculations
hardcoded to font size 9?

Re: [flexcoders] how can i get a columnIndex from an item in my TileList?
Just a thought (though not an answer), it might be a better idea if within your custom tooltip component you evaluated the space needed by your tooltip compared to the space between your cursor and the side of the stage, then move the tooltip accordingly. That way you're taken care of regardless of the position or size of your tilelist or the items inside the tilelist. Hope that's relevant.

[flexcoders] Components as chart annotationElements
Hello all, I have a chart with a few annotation elements. The first is a canvas that covers the whole thing and does stuff like allowing me to drag the chart around. Then I added another canvas that contained a box. Basically I'm working out away to add some draggable vertical cursors. I wasn't liking the mouseOver behavior of the VRule; It only fired on the edges and not over the magical box between the edges. So, I made a 2 pixel wide Box with a filled in background (seems a little ghetto, I know). It worked right when wrapped in a Canvas with 100% height and width. So as a little proof of concept, the following code worked how I wanted. The chart was draggable everywhere except when the mouse was directly over the cursors. mx:annotationElements mx:Canvas id=chartArea width=100% height=100% buttonMode=true mouseDown=initiateDrag(theChart) / mx:Canvas width=100% height=100% mx:Box id=cursor x=50 height=100% width=2 backgroundColor=#00 / /mx:Canvas /mx:annotationElements As I wanted to add more properties and logic to the cursor, I extracted it out into a component. Now the component is a Canvas base, with the Box in it just as above, and some actionScript. And the above code now looks like: mx:annotationElements mx:Canvas id=chartArea width=100% height=100% buttonMode=true mouseDown=initiateDrag(theChart) / local:Cursor id=cursor x=50 width=10 / /mx:annotationElements The problem is that now, no matter how I set widths (in the main app or within the component), cursor covers chartArea starting at x and extending right to the end. The box width within the component works fine, but the whole canvas acts like 100% width starting at x, no matter what. That prevents the dragging and mouseOver behaviors I want on chartArea. So for example, with the above, I can drag the chart as long as I press the mouseDown between 0 and 49 for x, and anywhere from 50 and beyond fires the mouseOver for the cursor instead. If you add more than one cursor, the layering continues in the same manner. So my question is, why does extracting it out to a component change that? What should I be doing to get the original behavior where the whole component can just be the width I set? Thanks!

[flexcoders] Resetting an application's view for new user
Hey flexers, I have a hefty AIR application with many different view combinations, forms filled with data, etc. When a user logs out and a different user logs in, I need the application to be reset so that everything looks as though no other user was previously logged in. I've ran into two solutions: 1) Reset all the forms, views, etc to their original state when the first user logs out. This can be tricky getting everything back to its initial state. 2) Make the main view (what would be the main application file in option #1) a separate component. When the user logs out, let the whole component get garbage collected. When the new user logs in, reinstantiate the main view to ensure its all in its initial state once again. With this option, there's not as much worrying about whether you've successfully reset everything since it's a brand new instance. However, processing time and memory management may be a new issue to deal with. So, I'm curious, how do you folks go about this in your projects? Thanks! Aaron

When a collection gets filtered, the filter function is applied to
each item of a collection separately. So the passed parameter for the
filter function is always an item of your collection. In your case the
collection contains strings. The filter function receives the string,
all you have to do in the function is to compare it to your filterText
string.
To do that Josh casted the passed parameter as a string to compare it
to the filterText variable.

I can get the following command to 'apparently' launch the app: String cmd = /bin/sh DISPLAY=:5 /opt/sfw/bin/firefox + url+ -width 1600 -height 1200; I say apparently because it does not cause any errors. But when I send messages to the flex app via BlazeDS for it to do it's thing...they never get there.

RE: [flexcoders] Flex TextArea Limited by number of lines.
My approach is to simply reject any change that would exceed the maxLines
setting.
The following is presented sans the requisite class structure.
Create a component that extends TextArea, then:
var tf:TextField = TextField(this.textField);
var maxLines:uint = 5; // however many lines (getter/setter)
var storedInput:String = ;
private function onChange(event:Event):void
{
if (tf.numLines maxLines)
{
tf.text = storedInput;
}else{
// Handle editable TextArea bugs
storedInput = tf.text;
}
}
Issues:
There is a bug in the TextArea component (editable=true) where any given
line will fail to wrap so long as the last character in the line is a space
(also, the insertion cursor disappears beyond the right edge of the field.)
But this can be managed.
Using htmlText just makes a mess (the insertion cursor has a mind of its
own.)

This hasn't been a common request. What is your use case for allowing a user
to type up to, say, three lines but no more? Most UIs I've seen limit the
number of characters you can type, not the number of lines.
I think you have two choices: use the 'textInput' event to limit the amount
of text that goes in, or use the 'change' event to remove excess text that
has already gone in.
Which are you trying, and what problems are you running into?

anyone else found the solution to this one?
Here is the code:

var printJob:FlexPrintJob = new FlexPrintJob(); //
Create an instance of the FlexPrintJob class.
var printADG:PrintAdvancedDataGrid = new
PrintAdvancedDataGrid(); // Initialize the PrintAdvancedDataGrid control.
if (printJob.start() == true)
{
printADG.includeInLayout = false; // Exclude the
PrintAdvancedDataGrid control from layout.
printADG.source = memberRpt; // Provide the data
source for the report
addChild(printADG); // Add the print-specific
control to the application.
printJob.addObject(printADG,

Subject: [flexcoders] Resetting an application's view for new user
Hey flexers,
I have a hefty AIR application with many different view combinations,
forms filled with data, etc. When a user logs out and a different user
logs in, I need the application to be reset so that everything looks
as though no other user was previously logged in. I've ran into two
solutions:
1) Reset all the forms, views, etc to their original state when the
first user logs out. This can be tricky getting everything back to its
initial state.
2) Make the main view (what would be the main application file in option
#1) a separate component. When the user logs out, let the whole
component get garbage collected. When the new user logs in,
reinstantiate the main view to ensure its all in its initial state once
again. With this option, there's not as much worrying about whether
you've successfully reset everything since it's a brand new instance.
However, processing time and memory management may be a new issue to
deal with.
So, I'm curious, how do you folks go about this in your projects?
Thanks!

How are you updating the item? If you use the collection API, the UI should

Hi Josh
Thanks a lot, That works perfectly for my arrayCollection. Now I already
have a project in which the data provider for my List is Array and I need
the same filter functionality for the Array. can we do this filter for Array
too or do i have to change the code of my project and instead of array I
need to store complete data in ArrayCollection instead of Array and then
made that filter working. It's just lot of work to change the existing

[flexcoders] Bounce: Favorite Flex/Flash drawing tool component
I was wondering whether anyone had any suggestions/favorites for a flex/flash based drawing tool component. That is, be able to load an image (from server) on to a canvas, mark it up with the standard drawing tools, then save back to the server. Don't need to maintain the graphics layers. Ideally be able to pick from list of templates for drawing starting point. Anyone? Restriction: We are still on Flex 2 (backend = java)

*Subject:* [flexcoders] Resetting an application's view for new user
Hey flexers,
I have a hefty AIR application with many different view combinations,
forms filled with data, etc. When a user logs out and a different user
logs in, I need the application to be reset so that everything looks
as though no other user was previously logged in. I've ran into two
solutions:
1) Reset all the forms, views, etc to their original state when the
first user logs out. This can be tricky getting everything back to its
initial state.
2) Make the main view (what would be the main application file in option
#1) a separate component. When the user logs out, let the whole
component get garbage collected. When the new user logs in,
reinstantiate the main view to ensure its all in its initial state once
again. With this option, there's not as much worrying about whether
you've successfully reset everything since it's a brand new instance.
However, processing time and memory management may be a new issue to
deal with.
So, I'm curious, how do you folks go about this in your projects? Thanks!

Re: [flexcoders] Disable Column reordering on Advanced Data Grid?
We had a similar challenge except we needed to persist to the DB the
rearrangement of columns...to do this, we extended the event class for
our listeners so we could capture column selection events...You might
try using the same thing and on column selected, perform a
preventDefault() which would halt any action from happening...
Here's the class:
package com.ftdna
{
import flash.events.Event;
public class ColumnSelectedEvent extends Event
{
public var colIdx:int;
public static const COLUMN_SELECTED:String = columnSelected;
public static const LABEL_SELECTED:String = labelSelected;
public static const COLUMN_DROP_TARGET:String = columnDropTarget;
public function ColumnSelectedEvent(type:String, colIdx:int)
{
super(type);
this.colIdx = colIdx;
}
override public function clone():Event
{
return new ColumnSelectedEvent(type, colIdx);
}
}
}
And here is an application of the class:
adg.addEventListener(ColumnSelectedEvent.COLUMN_SELECTED, denySelect)
private function denySelect(event:ColumnSelectedEvent):void
{
if (event.type == ColumnSelectedEvent.COLUMN_SELECTED)
event.preventDefault();
}

Subject: [flexcoders] Generic itemRenderer for Canvas based controls
I have a TileList control that I want to populate at runtime with a
collection of custom controls determined by preferences held on the
user which I retrieve after they log in. All of the custom controls
are based on Canvas.
My current approach is to have an Array into which I push the
appropriate controls after login success and bind that array as the
dataProvider on my TileList control. The trouble is that the controls
don't get rendered because there is no itemRenderer defined for the
TileList.
So I attempted to create a generic itemRenderer based on Canvas which
overrides the set data() method and adds the inbound control as a child...
override public function set data(value:Object):void
{
if (value == null) return;
var cvs:Canvas = value as Canvas;
this.addChild(cvs);
}
However, this throws index out of bounds errors doing a getChild(0)
deep in the bowels of the framework code associated with the dynamic
itemRenderer component, which I don't seem to be able to overcome in
spite of altering the sequence in which things get created, and
fiddling around with the creationPolicy of the custom controls.
So I'm a bit stuck and wondering whether there is a different approach
or I'm just doing something wrong.
Any ideas?

Re: [flexcoders] Component Life Cycle
I think I understand your question. Try throwing this in your component
(outside of any methods/properties) and tweaking for your needs:
// Default styles
//
private static var classConstructed:Boolean = classConstruct();
/**
* @private
* Creates default styles that can be overridden by the developer.
*/
private static function classConstruct():Boolean {
var styleDeclaration:CSSStyleDeclaration =
StyleManager.getStyleDeclaration('Cursor');
if (!styleDeclaration) {
styleDeclaration = new CSSStyleDeclaration();
}
styleDeclaration.defaultFactory = function():void {
this.color = 0xFF;
}
StyleManager.setStyleDeclaration('Cursor', styleDeclaration,
false);
return true;
}
Note that Cursor is the component's name. This way of setting a default
style personally seems rather unorthodox but it's the only way I've seen
that works. I hope a better/developer-friendly approach is offered in
future versions of Flex.

[flexcoders] Re: Unformatting currency values - best practice?
Thanks very much for those suggestions. The RegExUtil class is almost perfect, except that it will strip out decimal places since they are non-numeric characters. In the focus in/out events I am trying to assign the numeric value of the TextInput's text property to the data property minus the currency symbol and thousands separator. The tricky part is the decimal place. The RegExUtil strip function will remove the decimal place since it is a non-numeric character and so the value saved to the .data property is wrong. The other thing to consider is that for some locales, a comma is used for a decimal point. So if we want to save this back to the database, the comma has to be replaced with a period. This shouldn't be too hard though - I'll just use string functions to find the decimal character, then split the number into 2 parts, strip the extra characters with the RegExUtil function and then concatenate them back with a . character to save to the db. Thanks again.

The whole idea that you could embed a font that isn't compiled into the file at compile time doesn't make any sense. The font has to be compiled into a swf or swc file for it to be embedded at all. You can't go back later after it's compiled and compile in more or fewer fonts. HTH; Amy
[flexcoders] Re: Unformatting currency values - best practice?
Just change the pattern: public static var NON_NUMERIC_CHARACTERS_WITH_DECIMAL : String = [^0-9|^.]+; For the locales that require a comma, use replace(). -TH --- In flexcoders@yahoogroups.com, flexcoder2008 [EMAIL PROTECTED] wrote: Thanks very much for those suggestions. The RegExUtil class is almost perfect, except that it will strip out decimal places since they are non-numeric characters. In the focus in/out events I am trying to assign the numeric value of the TextInput's text property to the data property minus the currency symbol and thousands separator. The tricky part is the decimal place. The RegExUtil strip function will remove the decimal place since it is a non-numeric character and so the value saved to the .data property is wrong. The other thing to consider is that for some locales, a comma is used for a decimal point. So if we want to save this back to the database, the comma has to be replaced with a period. This shouldn't be too hard though - I'll just use string functions to find the decimal character, then split the number into 2 parts, strip the extra characters with the RegExUtil function and then concatenate them back with a . character to save to the db. Thanks again.
Re: [flexcoders] Resetting an application's view for new user
Yeah, I think that would be akin to the first option described in my initial
email. The difficulty with that is making sure that all state variables
really do get reset. If new view combinations are added to the system
later, the developer is required to ensure they are also included in the
reinitialization process. Something that really ensures that everything is
at a clean slate and doesn't leave room for error on the developer's part
would be really nice. Tracy's recommendation is great for that since it
basically re-loads the SWF completely, but I'm not sure there's an AIR-based
alternative.

Hey flexers,
I have a hefty AIR application with many different view combinations,
forms filled with data, etc. When a user logs out and a different user
logs in, I need the application to be reset so that everything looks
as though no other user was previously logged in. I've ran into two
solutions:
1) Reset all the forms, views, etc to their original state when the
first user logs out. This can be tricky getting everything back to its
initial state.
2) Make the main view (what would be the main application file in option
#1) a separate component. When the user logs out, let the whole
component get garbage collected. When the new user logs in,
reinstantiate the main view to ensure its all in its initial state once
again. With this option, there's not as much worrying about whether
you've successfully reset everything since it's a brand new instance.
However, processing time and memory management may be a new issue to
deal with.
So, I'm curious, how do you folks go about this in your projects? Thanks!

[flexcoders] Re: Component Life Cycle
Hi Aaron,
Thanks for you reply. I was just wondering that I am currently doing
the styling in initialize() method. So the charts is not rendered until that
time, so why is the default flex axis is getting rendered.
When the chart is rendered my styles should already be set.
So how the updateDisplayList() method is getting called. I need to get
my styles set before the updateDisplayList() method is called.
Do you have any idea if preinitialize() method help ??
Thanks

I get bogged down on how to create the server side application and connect it to Flex. Can anybody point me in the right direction?
[flexcoders] Re: Data not appearing in AdvancedDataGrid
Two things:
- Try stuffing the raw XML into a TextArea to see what it looks like.
You could bind it directly to the ADG without first converting to
array/arraycollection; that's the beauty of the e4x format you're
using on the HTTPService call. Not sure why you're doing the
conversion to an array and then to an arraycollection. If you need to
modify the values when they're displayed, try using the labelFunction
on each column.
- When I run into issues in code, I try to make it as simple as
possible, make sure that works, then add the additional pieces back in
one by one until I can see what's causing it to act funny.
I'm thinking something's not quite right with the data after you
manipulate it. Look at that piece.

[flexcoders] Tricky one...adding attachments to an email generated from the app
Hi guys, And yet another one that I haven't seen... Part of our app allows a user to send an email to one or more folks in their view. We simply provide a state that has a simple email form they fill out and then we pass that information back through our web service (.NET) that actually has the procedure to send the email. What I need to be able to do is allow the user to add attachments to the email they want to send out. Is there any way to do this and is there a better method to the email solution? We briefly toyed with the idea of just creating the hyperlink to use their own email client, but a user can literally send a bulk email to several thousand people and a hyperlink would die a slow, miserable death trying to handle that.

Perhaps you could gather the attachments in flex, add a parameter to your webservice for them, base64 encode them for transfer via that parameter, then base64 decode them back to binary files on the server when sending the email?

initial state.
2) Make the main view (what would be the main application file in option
#1) a separate component. When the user logs out, let the whole
component get garbage collected. When the new user logs in,
reinstantiate the main view to ensure its all in its initial state once
again. With this option, there's not as much worrying about whether
you've successfully reset everything since it's a brand new instance.
However, processing time and memory management may be a new issue to
deal with.
So, I'm curious, how do you folks go about this in your projects? Thanks!

It is possible of having a datagrid for the footer information under
the one of the data table.
It's simpler to handle but the behavior is not as smooth as in Alex's

dropped the column bar into its new position.

[flexcoders] ExtJS like features in AdvancedDataGrid
Looking at any pointers in how to create column filters/show-hide much like in ExtJS Grid. I've been reading Alex's itemRenderer blog only to be a little overwhelmed at how complicated this might be to accomplish. http://extjs.com/deploy/dev/examples/grid-filtering/grid-filter.html Is there any 3rd party ADG grid component that enhances the out of the box ADG functionality? Specifically adding some line of business abstractions like column type (Text/Date/Number) and filtering/grouping widgets that an end user can use. Here is how I plan to accomplish some of the features: - Column Type -- add a sortCompareFunction based on column meta data - Arrow icon -- add Arrow icon to column header that would have handle click event - Context menu -- add menu control to support multi panel context menus. This will require the ability to format menus with checkboxes (never done this) Thoughts on this approach?

[flexcoders] Method variable scoping problem with Flex compiler
I came across another scoping issue today that scared me. I sure wish
that the scoping in the ActionScript language worked the same way C++,
C#, Java, and others work!
Here's the code:
for each (var o:Object in myArray)
{
var myProblemObject:ProblemObject;
if (some condition)
{
myProblemObject = new ProblemObject();
... more code here ...
}
... still more code here...
if (myProblemObject)
{
... do some stuff ...
}
}
In this code myProblemObject is NULL when things start out...great!
The problem comes after an instance of myProblemObject gets created.
Every time through the loop after this myProblemObject is no longer
NULL. This is not consistent with any other language that I have
worked with and is therefore not obvious to the developer working with
the code.
Why is myProblemObject not reset each time through the loop? It is a
variable declaration.

[flexcoders] Re: Unformatting currency values - best practice?
It sounds like you're taking the 'high road' approach to this (i.e., letting users enter arbitrary currency strings and then trying to figure out the currency type after the fact and then checking the thousands separators and decimal point characters to see if they match that). That's a best practice usability-wise (at least if you agree with Alan Cooper...), but it can also take a lot of code to implement it robustly and it requires thorough testing. If you're willing to trade off some usability, you could have user's pick the currency type (i.e., USD, Euro, Yen), _separately_, say in a drop-down list; and then have them enter the actual value (in a separate text field). If you implement it that way, then your (currency) string parsing problem becomes much simpler. If you put the currency type selector _before_ the amount field (in the workflow/tab order), then you can also do things like dynamically changing the validator for the amount field, based on the selected currency. You could even have a 'no currency type selected' default for the currency type selector and disable the amount field until the user selected a particular currency. I don't know if I would consider the latter approaches as 'best practices' (especially from a usability perspective), but they are reasonable trade-offs. YMMV. I'm not quite clear on what you're trying to do formatting wise, however. Are you saying that you try to detect when a user has finished entering a currency amount, and then add currency symbols, thousands separator symbols, decimal point symbol, etc.? Regards, Jim --- In flexcoders@yahoogroups.com, flexcoder2008 [EMAIL PROTECTED] wrote: What is the best practice or a good recommendation for formatting currency values and then removing the currency formatting for saving to the database? Here's what I have attempted to do so far. It works - but only if the user enters plain old numbers - if they add any currency symbol or thousand separator, it fails. I have a form which has some textInput's that are formatted with currencyFormatters. I initialize each textInput's .data property to 0. The textInput displays formatted currency amounts from xml data retrieved from the database. On the focusIn event, the text property is assigned to the textInput's .data property, so the value stays the same but the formatting is gone. And when a change event fires, the unformatted text in the textInput gets updated to the data property as well. On the FocusOut event, the currency formatting is re-applied. When I save to the db, I use the textInput's .data property. So for the most part this works, but fails if the user enters any currency symbols. Is there a good class or function someone could recommend to take a currency value in a textInput and strip out all the extra formatting characters? I am also trying to implement localization, so the various currency symbols will be different depending on the locale. Thanks
RE: [flexcoders] Method variable scoping problem with Flex compiler
Fact of life with ECMAScript (hence, with ActionScript as well).
Take a look at the language specification itself for details, but locals in
your example are scoped to the function, not to code blocks within the function
delimited by braces. Yes, this differs from C-based languages, and as someone
who regularly works in both I've been bitten by this more than once as well.
Best,
Seth

Re: [flexcoders] Fwd: Filtering the List Entries depending upon the text entered in text Input box
Never bind to array, and also when you call array.filter() it will make a
duplicate Array, things you change there won't get changed in your source
(depending on references etc). You don't need to totally change your code,
just create a new ArrayCollection using your existing array as the source.
Whenever you add or delete items using the ArrayCollection, it will update
the Array for you, and when you set a filter on ArrayCollection it only
updates when it needs to, it's pretty smart. Then you just bind to the
ArrayCollection instead of the Array for the dataProvider of your List or
DataGrid or whatever.

RE: [flexcoders] Re: Using RMTPS channel
The NetConnection.Connect.SSLHandshakeFailed status indicates that the platform SSL library for the machine you're running the player on decided not to complete the handshake for some reason. Unfortunately, the platform library doesn't give the player much in the way of useful detail... I think the most probable reason for the failure in your case is the use of an IP in the CN field of your cert. You should use an actual domain name instead. DynDNS can be a great way of creating a test domain name to use for this sort of testing.

Thank so much for your help Seth --- In flexcoders@yahoogroups.com, Seth Hodgson [EMAIL PROTECTED] wrote: The NetStatusEvent underlying the connect error you're seeing has the code: NetConnection.Connect.CertificateUntrustedSigner This indicates that the connection is being closed because the server certificate (self-signed in your case) that you're using for your SecureRTMPEndpoint is not in your browser's trust store. This wouldn't be an issue if you were using a cert signed by a CA, but can be more trouble when dealing with self-signed certs. You need to import the server certificate into your browser's trust store - Googling around should get you the info you need. Also, the name in your server cert should match the domain name the client is hitting, in this case, 10.100.72.165, so that might be something else to double check. Other than that, your configuration looks fine based on a quick skim.

Part of our app allows a user to send an email to one or more folks in their view. We simply provide a state that has a simple email form they fill out and then we pass that information back through our web service (.NET) that actually has the procedure to send the email. What I need to be able to do is allow the user to add attachments to the email they want to send out. Is there any way to do this and is there a better method to the email solution? We briefly toyed with the idea of just creating the hyperlink to use their own email client, but a user can literally send a bulk email to several thousand people and a hyperlink would die a slow, miserable death trying to handle that.

[flexcoders] How to display special characters like #176; in ComboBox list
The special character numeric references work fine in Label and Text and such, but are interpreted literally in a ComboBox's drop list. Any sugestions? Tracy

Never bind to array, and also when you call array.filter() it will make
a duplicate Array, things you change there won't get changed in your source
(depending on references etc). You don't need to totally change your code,
just create a new ArrayCollection using your existing array as the source.
Whenever you add or delete items using the ArrayCollection, it will update
the Array for you, and when you set a filter on ArrayCollection it only
updates when it needs to, it's pretty smart. Then you just bind to the
ArrayCollection instead of the Array for the dataProvider of your List or
DataGrid or whatever.

I would be able to successfully implement the same code with Array
instead of ArrayCollection but there is no method name array.refresh,
However there is method named ArrayCollection.refresh which is responsible
for refreshing my list. How do I refresh my array?Does anybody know
equivalent method to refresh array in the list? Below is the code except in
the processfilter I need to refresh array.
Thanks for your help

Hi Josh
Thanks a lot, That works perfectly for my arrayCollection. Now I already
have a project in which the data provider for my List is Array and I need
the same filter functionality for the Array. can we do this filter for Array
too or do i have to change the code of my project and instead of array I
need to store complete data in ArrayCollection instead of Array and then
made that filter working. It's just lot of work to change the existing
workign code with my harsh deadline.
Please let me know which is the best way.
Again I highly appreciate your help
