Flex :: Validator On RadioButtonGroup Of 2 Radios

Oct 29, 2010

I have a Validator on a RadioButtonGroup of 2 Radios. There's a checkbox above the RadioButtonGroup whereby if checkbox.Selected, then the Radios are enabled. So the Validator is required if the checkbox.Selected. So far so good. The problem is once a radio gets selected, the RadioButtonGroup selectedValue gets set. When I uncheck the checkbox I set the radios to not selected, but the selectedValue on the RadioButtonGroup doesn't get reset -- it hold the previous value. I tried setting it to null but no luck.

Therefore if I check the checkbox again and submit, the Validator see a selectedValue on the RadioButtonGroup. Even though none of the radios are selected, validation passes. How can I reset the RadioButtonGroup to its initial state when I uncheck the CheckBox? I looked at the underlying code for RadioButtonGroup.selectedValue = null, and what it does is look for a radio in the with the parameter value. If it doesn't find it nothing gets set.

I'm working on a flex 3 application which will initially support only one language (which is not English) but may need to support English and other languages later. So I'm using the standard localization technique, with resource bundles. Now, somewhere I use the validators like EmailValidator which have some error messages displayed, these are in english and come with the flex sdk. How do I localize those messages?

Flex :: Custom Validator Against Remote Object?

Oct 20, 2010

I have a need to validate a field against our database to verify unique-ness. The problem I seem to be having is that the validators doValidation() exits before we've heard back from database.

How can I have the validator wait to return its payload until after we've heard from the DB?

Or perhaps a better question might be (since I think the first question is impossible), how can I set this up differently, so that I don't need to wait, or so that the wait doesn't cause the validation to automaticallly return valid?

Flex :: Dispatching Custom Events From A Validator?

Aug 2, 2011

Basically I am trying to create a string Validator which requests a new language from its controller by dispatching an event upon its creation.

The example below is a straight copy from the Flex3 component explorer - the only diffrence being that I have created the validator as a custom component which dispatches an event upon its creation.

The problem is that my main Application cannot hear the event being dispatched and I don't know why.

Here is the example

MyValidator.as

package components
{
import flash.events.Event;

Actionscript 3 :: Flex Email Validator - £ Symbol Allowed In Domain Name?

Apr 20, 2011

I have a bug to fix in work where the UK Pound symbol, £, is allowed in the domain name. I checked the EmailValidator source and can see that it is not a disallowed symbol, whereas things like the dollar sign are:

public class EmailValidator extends Validator
{
include "../core/Version.as";

[code].....

As you can see DISALLOWED_DOMAIN_CHARS string does not include the £ sign. Was thinking of monkey patching (basically copying the entire class, editing it, and adding it to my src - for those not in the know), but we use RSL's, so that would be problematic.

Flex :: Caret On TextInput Never Goes Away

Jan 29, 2011

I have a login form with various textInputs and a submit button. If you submit proper login credentials the system unloads the login view and loads the app view. Pretty standard. Unfortunately I've noticed this weird bug where if you hover over one of the textInput boxes with the mouse, then fill the form using only the keyboard (and leave the mouse parked on top of the textInput), and then tab to the submit button and press the space bar, i.e. login via keyboard, the mouse cursor will remain a caret in the new view, no matter what you do (move, click), until you find another textInput to undo the cursor state. I've tried to do all sorts of stuff via CursorManager but nothing seems to do the trick. I've tried dispatching events ROLL_OUT or MOUSE_OUT events to the textInput but that doesn't do the trick either.

Flex :: How To Implement HTTP Tunneling

Jul 26, 2009

I've written a Flash (Flex) client connecting to a back-end server to exchange data. I've also written my server from scratch, and it serves two purposes:

(1) Web (HTTP) Server- By default listens on port 80

(2) Socket/Application- Server - By default listens on port 443

Just FYI, both servers run in the same process space, for convenience reasons. They are not expected to handle massive loads, so I'm fine with that. As soon as the Flash client is served to the browser from the HTTP socket, the client attempts to open an XMLSocket to the Socket/Application server. I now want to implement HTTP tunneling, so that my client can connect to the Application server even if the user is behind a firewall. I do not want any external servers involved (proxies etc.) - simply use the servers I already have.

My questions:

(1) Is it better to use port 443 for that? (does it better fool firewalls?)

(2) As far as I can see, what I am required to do, is just ensure that my actual application data is simply encapsulated in an HTTP structure (preceded by a dummy HTTP header), both from the client and server sides. Is that so or am I missing anything here?

(3) Do I need to keep hiding/encapsulating my data every message I send through the socket, or can I just encapsulate the first message when opening the connection?

Flex :: Possible To Implement Facebook In Adobe?

Feb 13, 2010

I am considering creating a website with the complexity of Facebook that should be able to scale into the millions of users. My question is: Is there any reason not to use Adobe Flex for such large project apart from the obvious point of requiring everyone to have Flash installed and not having to rely on Adobe? In my view Adobe Flex would reduce the server load for Facebook, because more of the work could me done on the client side.

If you use the mac, the behaviour I'm looking for is something like what the Dock uses; when you drag something out of the bounds of the control it should get an icon that indicates that it'll be deleted (OSX uses a cloud or something?) and then if you release it it will be removed from the list.

Actionscript 3 :: Implement Encryption In Flex 3?

Apr 12, 2011

we have one application where we are pulling some confidential information from one of the product design tools. So we have used HTTPS as the channel and also we are encrypting the Request Parameters and Some data before we sent it to Web Services.Everything seems OK.But when we gave the application for Security auditing they found we have hard coded the encryption key in source code. They have used Sothink SWF Decompiler to look into my SWF file. They caught the key and raised concern over it.

We have developed this application using Flex 3(SDK 3.4). Is there any best way to use Secret key without being hard coded in source code. If anybody come across this kind of problem, please let me know. use the secret keys in SourceCode without being Hard coded.

Here is my sample code:

var currentResult:String = "";
var strDataToEncrypt:String = "";
var kdata:ByteArray;
