[flexcoders] Styling Alert box default button
I have a custom styled alert box with two buttons (ok and cancel), I'm trying to make the default button look slightly different, but I can't figure out how to do this. Does anyone know? The default style can achieve this.
[flexcoders] Reclaiming memory from removed viewstack children
I have a fairly simple app that I made as a test, confirming what I've read elsewhere. It seems that when a layer is removed from a viewstack using removeChild or removeAllChildren the memory is not garbage collected. In this example i have a simple viewstack that adds a few layers of a component with a chart on it (using anychart). When I create the layers, it's fine, but when I delete them, the memory stays up and the instances of the chart don't decrease... do this enough times, and it'll crash your browser. Does anyone know how I can really delete a child layer? Here's some code: http://pastebin.com/faf14977 Thanks! Adam
[flexcoders] get an object with a name
I have some custom validation and now I have a problem.. I'm creating validations dynamically as part of the actionscript that I use to create the numberValidator I have this line: thisValid.addEventListener(ValidationResultEvent.INVALID, handleInvalidEvent); In the handleInvalidEvent method i need to get the object that is being validated. in this case it's a textbox. There is a field property for the ValidationResultEvent event, but now I need to get the actual object. is there a way to get the object from the name? Thanks, Adam
[flexcoders] linkbar removeAllChildren error in safari.... ???
I have a strange error... I have a linkbar that is being dynamically populated. I need to be able to refresh the link bar. So I have this code: http://pastebin.com/m78e78eb0 When I click the clear button which calls removeAllChildren() for the linkbar, I get this error: TypeError: Error #2007: Parameter child must be non-null. at flash.display::DisplayObjectContainer/getChildIndex() at mx.core::Container/http://www.adobe.com/2006/flex/mx/internal::rawChildren_getChildI ndex()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\core\Container.as:3879] at mx.core::Container/http://www.adobe.com/2006/flex/mx/internal::rawChildren_removeC hild()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\core\Container.as:3813] at mx.core::ContainerRawChildrenList/removeChild()[E:\dev\3.1.0\frameworks\projects\fra mework\src\mx\core\ContainerRawChildrenList.as:157] at mx.controls::LinkBar/childRemoveHandler()[E:\dev\3.1.0\frameworks\projects\framework \src\mx\controls\LinkBar.as:560] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() etc, etc... What's really weird is that I only get this error when using safari. If I look at the same code using firefox, I get no error. Does anyone have any clue what I'm doing wrong? I really need to be able to do this, and I can't seem to find a solution. Thanks!! Adam
[flexcoders] Re: tree event using cairngorm
Thanks Tom!
I was able to pass the tree into the events and it worked as I had hoped. I
ran into another
problem, and I thought I'd ask you about it.
In my original tree code, i have a method that calls the webservice and looks
like this:
var token:Object = facility.folderService.send(parameters);
token.expandIDs = expandIDs;
token.parent = list[0];
token.eventType = (expandIDs.length 1) ? init : change;
where I'm setting some items asyncronously ( i think! )
Now if I have in my command the webservice call:
var parameters:Object = {folderID:[EMAIL PROTECTED];
var event:GetTreeXMLEvent = new GetTreeXMLEvent(model.user.token, _Tree);
I don't know how to pass items like parent, etc. Any suggestions? I really
appreciate the
help.
Thanks,
A

We pass the tree into the Event, and save a copy of this in the Command
before
calling the Delegate.
When it returns, you've got the tree to hand then.

[flexcoders] tree event using cairngorm
Hi Everyone! I'm trying to write a dynamic tree using cairngorm, and I ran into a problem. I want to be able to expand a node, have it go to my webservice, return the xml and open the node. In the command that is handling the response to the webservice, i need to call the expandItem method of the tree. And there's the trouble... How do I call a method for a flex tree from a cairngorm command? Any suggestions?? Thanks, Adam
[flexcoders] Cairngorm Dynamic Tree
I currently have a tree that will hit a webservice when you click to expand a
node. It works
great! My problem is that I'm trying to implement this in an app using the
Cairngorm
framework and I'm hitting a road block... I want to write a method that will
search the tree
for a node. Keeping in mind that the tree is not all there since I build it
dynamically, my
webservice for the search returns the nodes that have to be expanded to find
the item. So
i need to call the method to expand the tree from within the framework and I
don't know
how to do this. Here's some code:
here's the code from the view with the tree:

[flexcoders] Custom Data Descriptor
I'm trying to use a specific XML fill to fill a tree and I'm assuming I need to use a custom data descriptor, but i can't figure out how to do that.

[flexcoders] Cairngorm app with HTTPService
I'm having a hard time learning Cairngorm, but I'm determined to
figure it out!! My current problem is with my HTTPService. In my
Delegate, I'm calling the service like this:
public class ContactListDelegate
{
private var responder : IResponder;
private var service : Object;
public function ContactListDelegate(responder:IResponder)
{
this.service =
ServiceLocator.getInstance().getHTTPService(ListContactsHS) as
HTTPService;
this.responder = responder
}
public function list():void
{
var token : AsyncToken = service.list();
token.resultHandler = responder.result;
token.faultHandler = responder.fault;
}
public function listResult():void
{
responder.result(responder);
}
}
and then in my services.mxml i have this:
mx:HTTPService id=ListContactsHS
url=http://localhost:3004/webservice/list;
useProxy=false
method=GET
makeObjectsBindable=false
result=event.token.resultHandler(event)
fault=event.token.resultHandler(event) /
(the service is written in Rails and on the local machine)
When I call the event to get the data from service though, I get this
error:
Error: C0008E: HTTPService not found for ListContactsHS

[flexcoders] Cairngorm web service not getting results
I have a small login app that is calling a web service to determine if
the login is valid. The web service currently only returns a string.
Here is the code:
in Services.mxml
mx:WebService id=Service
wsdl=http://localhost/GSSData/service.asmx?WSDL;
showBusyCursor=true
useProxy=false
makeObjectsBindable=false
/mx:WebService
in LoginDelegate.as:
public function login (loginVO:LoginVO):void{
service.loadWSDL();
DebugWindow.debug(service.wsdl: + service.wsdl.toString());
var token:AsyncToken = service.login(loginVO.username,
loginVO.password);
DebugWindow.debug(After login: +
token.result.toString());
token.addResponder(responder);
}
My problem is that I am seeing the web service get called and the
response is returned, but it doesn't seem like my app is taking the
response. When I try to view the response in my debug window i get an
error:
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
as though the web service isn't returning a value. I'm totally at a
loss here, I'm trying to learn Cairngorm, but i'm really struggling.
I basically am trying to rework this sample app:
http://www.alex-uhlmann.de/flash/adobe/blog/cairngormlogin/CairngormLogin.html
to use a web service and I having little to no success. can anyone
see what I'm doing wrong?
Thanks,
A
