[flexcoders] Emulating a failed validator
Guys, Say I have a textInput, and I need to emulate the failure of a validator, how do I go about it? I can't use the existing validator framework, because the decision on whether or not that field is valid is based on a calculated result rather than a simple validation of the textInput component itself.

RE: [flexcoders] chart data change events
When the dataprovider changes, each series's protected dataChanged function gets called. Also, you could access the chart's dataProvider as a ICollection and add an event listener to it to keep track of the data changes. Thanks -Sunil From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of netdeep Sent: Thursday, May 22, 2008 11:25 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] chart data change events I need to capture an event for when the data is updated in a chart. I take a snapshot of the chart and save it to a file. But when I do it via a custom event which I fire myself, it fires the event and takes the screenshot before the update and so just snapshots the previous state of the chart. And if I use FlexEvent.UPDATE_COMPLETE, it doesn't register a change since what I am doing is adding data to the array which is the dataProvider for the chart. I can't put an update event listener to the array itself since the array does not have any way to reference back to it's chart. Any help would be greatly appreciated image001.jpgimage002.jpg

[flexcoders] XML to Object
Hi, I am using a HTTPService which has resultFormat as e4x. I need to convert the XML obtained to an ArrayCollection containing objects. I tried this: var ac:ArrayCollection = new ArrayCollection([(event.result.abc as XML).children()]); This gives me an array collection of XML objects. But, I need an array collection of Objects. Is there any ways I could get that. Also, I cant use the resultFormat=object, as in my XML I have two sets of Data. The first one needs an e4x format and for the second one I need to get an ArrayCollection of Objects. Any help would be greatly appreciated. Regards, Gaurav

[flexcoders] Interesting XML performance discovery
Hi there
I'm busy crunching through xml data, stripping out nodes that don't
have children. Perhaps its not the best way to do things, but I use a
for loop that checks and deletes any item with no children. I've
always found XML delete tricky and to do this I reference the parent
which finds the child index and deletes the child.
On a file of 1+ items execution time is 600ms without the delete.
With the delete execution time is 52919ms!
I'm off to find another delete function ...
for each(span in body.span) {
if(span.children().length() == 0) {
delete span.parent().children()[span.childIndex()];
}
else {
[EMAIL PROTECTED] = SPAN_PREFIX + id++;
[EMAIL PROTECTED] = itemClicked('[EMAIL PROTECTED]',
AIR.itemSelected);
[EMAIL PROTECTED] = span.attribute(class);
}
}
[flexcoders] Re: Interesting XML performance discovery
... just discovered how terribly unoptimized code can be.
Changed the delete code snippet from the below example to the following:
delete body.children()[count]; // takes 53636ms
and then the following:
delete spans[count]; // takes 852ms
Obviously constructing a child array each time in the loop on a large
list of children is hugely inefficient.

[flexcoders] custom event not added
Hi there,
I have a controller that is adding my custom event listeners, but for
some reason my event handler was not being fired.
My original code was (snippet):
(in controler)
//constructor
public function FlexbController()
{
//turn the key, start it up
addEventListener( FlexEvent.CREATION_COMPLETE, onInit );
}
private function onInit( event:Event ):void
{
//setup event listeners
/*systemManager is where event listener hangs out
defines the
relationship between event and handler*/
systemManager.addEventListener(
GetNewsEvent.GET_NEWS_EVENT,
handler_GetNewsEvent );
systemManager.addEventListener(
AddNewsEvent.ADD_NEWS_EVENT,
handler_AddNewsEvent );
systemManager.addEventListener( NewsDataLoadedEvent.NEWS_LOADED_EVENT,
handler_NewsLoadedEvent );
getNewsData();
}
And I had trace statements in all of my handlers... this is how i
noticed things were not working as they should.
SO I added a simple check like (in my FlexbController constructor):
if (systemManager.addEventListener( GetNewsEvent.GET_NEWS_EVENT,
handler_GetNewsEvent ))
{
trace(true);
} else {
trace(false);
}
And I obviously am getting false.

[flexcoders] Re: filterFunction problems being had
I kind of see what you're getting at, I'm thinking the ArrayCollection is probably not being returned as an associative array. I've double-checked and the col variable is containing the value of what I select in the comboBox yet value is not getting set equal to it so yeah value = item[col] works. Going by your suggesting of checking the field names, and all I had to do was make sure they matched and when they did, the function as a whole worked. Thanks, once again a mundane detail ruins my day, lol. Oh well, all part of the learning process. --- In flexcoders@yahoogroups.com, Tim Hoff [EMAIL PROTECTED] wrote: Hi Brian, The original example uses an associative array; which is an instance of the Object class. Because the example creates it's ArrayCollection in code, value = item[col] works: dpRows = new ArrayCollection(); var item:Object = new Object(); item.type = Website; item.name = Expectal.com; [EMAIL PROTECTED], bredwards358 bredwards358@ wrote: item.url = http://www.expectal.com;; item.desc = Your Professional Flash Photo Gallery with Slideshow and Background Music; item.tags = Flash, Gallery, Slideshow, Music; dpRows.addItem(item); However, if you are loading your DataGrid's ArrayCollection from a database, it's probably not being returned in an associative array format. If it is, check to make sure that the field names are exactly the same as the data values in the ComboBox ArrayCollection. If it's not, you will probably have to re-write the code to be conditional. You might also want to debug the col variable; to make sure that it contains a value. As a general recommendation, I would pay attention to naming conventions. Filters and Sorts are two distinctly different functions that may be applied to an ArrayCollection. (model.prodMaintData.filterFunction = sortProducts is confusing). Also, I would stay away from using the word data in name/value pairs. It works, but it's very close to being a reserved word in Flex. -TH

[flexcoders] Force redraw of a Linechart as seen on livedocs ?
Hi all !
I'm trying to implement the code found here
http://livedocs.adobe.com/flex/3/html/charts_intro_7.html#225506
It's the last part with the multiple line series.
My problem is that I'm updating the series based on a request instead
of populating it in the creationComplete()
The method described here is called on a resultEvent
public function initApp():void {
var wholist:Array = new Array();
for each(var property:XML in myXML.item.who) {
// Create an Array of unique names.
if (wholist[property] != property)
wholist[property] = property;
}
// Iterate over names and create a new series
// for each one.
for (var s:String in wholist) {
// Use all items whose name matches s.
var localXML:XMLList = myXML.item.(who==s);
// Create the new series and set its properties.
var localSeries:LineSeries = new LineSeries();
localSeries.dataProvider = localXML;
localSeries.yField = hours;
localSeries.xField = when;
// Set values that show up in dataTips and Legend.
localSeries.displayName = s;
// Back up the current series on the chart.
var currentSeries:Array = myChart.series;
// Add the new series to the current Array of series.
currentSeries.push(localSeries);
// Add the new Array of series to the chart.
myChart.series = currentSeries;
}
How can I redraw my line series, knowing that it's in a VBox in a
ViewStack ?
I've been calling validateNow() on a bunch of components...

[flexcoders] Wipe effects with perElementOffset in State Transitions and RemoveChild
Hi
Trying to use a wipe transition effect when changing states. I want to
use a perElementOffset so that the object wipes off and then gets
removed. I've already set wipe.showTarget to false, but the component
performs the wipe and then flicks back on? I'm pretty sure my code is
solid, I can replace the wipe with a fade and it works fine. I'm
wondering if this is a bug?
code-
mx:Sequence filter=remove targets={[b,c,d,e,can]}
mx:WipeDown showTarget=false perElementOffset=300 /
mx:RemoveChildAction perElementOffset=300 /
/mx:Sequence
Any suggestions?

[flexcoders] Re: chart data change events
The problem with the events is that if I listen to changes in the array, I don't have access to the chart when the event fires. You can't pass arguments to the event so the only thing it will know about is the array which fires it. And as I said before, when I create custom events, I have to dispatch them myself and they never get called when I need them to, but are always late. My best guess was to try FlexEvent.UPDATE_COMPLETE but that seems to never get fired when I simply append to the array which is the dataprovider for the axis. So I'm unsure what to do with these suggestions. Thanks, though! --- In flexcoders@yahoogroups.com, Sunil Bannur [EMAIL PROTECTED] wrote: When the dataprovider changes, each series's protected dataChanged function gets called.

What I found is that if the evt.result is a mysql/mysqli result set,
it fails to load data sent. However if you put the mysql data into a

However if you set the NewEntryArrayCollection up as so:
ac = new NewEntryArrayCollection (evt.result.source as Array );
It will accept a mysql/mysqli result set.

RE: [flexcoders] Re: How to extract data from XML
Ok, you may have a namespace problem. They can be a PITA. I'm not an expert and you should reveiw the docs/google if this doesn't work but try putting this in the declarations section of your app/component(instance scope level): default xml namespace = http://www.w3.org/2005/Atom;; There is more stuff in the xmlns declaration in your sample xml: feed xmlns=http://www.w3.org/2005/Atom http://www.w3.org/2005/Atom ... I do not understand what that second part of the string is. You might have to include that as well in the default namespace declaration. You can avoid the namespace issue if you use the node index to get a node, but this is a very clunky way to do it. To see, try: Alert.show(myXML.children()[4].toXMLString()) XMLList always has 0-n xml nodes in it. (the result of an e4x expression is never null) If there is only one node, then many of the XML methods will work on it the same as with XML. But for clarity, if I know I want to work with a single XML node then I do: var myXMLList:XMLList = myXML.logo; var xmlLogo:XML = myXMLList[0]; If just you do this below, you will get a datatype error: var xmlLogo:XML = myXML.logo; //even if that expression returns only a single node.

RE: [flexcoders] Re: Async Concurrent Requests with AMF for BlazeDS or LCDS
Hi Jay, You could fork the endpoint code and build your own custom AMF filter chain to do something like this, but the problem remains that when you receive a single HTTP request, you have to return all your results in a single HTTP response. Say you have 3 batched calls with average execution times on the server of 10ms, 6 seconds, and 50ms respectively. Even if you split these invocations out across concurrent threads in your custom AMF filter chain you'd still need to join on these threads, wait for them all to finish and then bundle the 3 results back up in a single response. So you're not really buying yourself much.. Which is why I recommend a truly async approach where your initial call just queues a job(s) for async execution on the server and you use the messaging infrastructure to get the eventual result(s)/fault(s) back to your client.

I digged through Blaze source code and found out that BatchProcessFilter is responsible for processing those messages . I am wondering is there any way, I can write our own batch process filter and plug that in instead of default one.

Basically, it would cut down the time server has to wait to finish processing all those messages sequentially. Any thoughts or insight info would be appreciated. Thanks, Jay --- In flexcoders@yahoogroups.com, Seth Hodgson [EMAIL PROTECTED] wrote: There is a single thread that advances through SWF frames and runs your ActionScript code and event handlers, but network calls are performed by separate background threads concurrently. In order to have calls processed concurrently on the server, they need to arrive as separate requests. In the case of AMF, if you make a series of calls quickly chances are good/excellent that the Player will batch them up and send them to the server in the body of a single HTTP POST. When this happens, the server must unpack them and process them serially and then pack the results for all these calls back up in the body of a single HTTP response. Because we're dealing with a single request and response, there's no way to send back results for individual calls separately. When these results get back to the browser and are passed back into the Player, they are dispatched to your ActionScript handling code as asynchronous events. There's not a good way to force calls to be sent as separate requests, and even if you could, browsers impose limits on the number of concurrent connections they'll open to a server, so this really isn't the right way to solve your scenario. Also, in the case of RTMP all traffic between the client and server happens over a single connection and is ordered serially. If you want to process calls/messages/data asynchronously on the server the proper way, it requires a bit of work on your part to accomplish at this point. Rather than running your current logic in your RemoteObject directly when it is invoked, you need to break that out into a Runnable class, and when you're invoked, create an instance of this class that packages up the incoming args and info about the client making the call and then submit that for asynchronous execution to a java.util.concurrent.Executor that you'd need to set up during server startup. Your remoting method could return a job id or just void once it has queued an instance of your Runnable with the Executor. On the client when you get a ResultEvent for your call you don't get the actual result - you just know that your invocation was successfully queued for asynchronous execution on the server. So the second half of the equation is how to get the result or fault generated when the Executor runs your Runnable back to the client. You need to take advantage of messaging in BlazeDS or LCDS to achieve this. In your client app, create a Consumer and subscribe to a destination you define that you can publish results/faults as AsyncMessages back to target clients from your Runnable. Your Consumer should subscribe to a subtopic that applies only to it, or use a selector expression. When your Runnable runs and generates the result or fault to return, you'd can create an AsyncMessage containing the result of fault info and publish it to this destination, using either a subtopic header, or some other message header that will be evaluated against the Consumer's selector expression such that the message is routed to the proper Consumer. That lets you return async results or faults to clients in a truly asynchronous manner.

RE: [flexcoders] Re: Async Concurrent Requests with AMF for BlazeDS or LCDS
Hi Tim, Yeah, it's the same issue. With proxied calls though, it's a bit more complicated to solve. In the remoting case, your remote object method is generally just doing some local computation on the server and maybe hitting a database. It's simple to wrap this up in a Runnable and execute it asynchronously. In the case of the proxy service, we use the Apache HttpClient library to make proxied calls on your behalf, and this would be _much_ harder for you to wrap up in a Runnable to execute concurrently. I'd like to see us support async mode for the proxy service as well as for the remoting service, and the proxy service itself should be updated to use NIO to support making proxied calls that don't tie up a server thread for the duration of the proxy request. Right now, in BlazeDS, because Servlet IO is blocking, when you make a proxy service call that hits our server the servlet request handler thread has to wait for the proxy request to return before it can return. So you tie up the thread for the duration of the call which could take awhile. Would you mind logging an enhancement request for async proxy service support in our bugbase?

[flexcoders] Tree node height problem on initial load
I have a component I'm developing to, among other things, accept an XMLListCollection as a dataProvider (the data is being supplied via a remote object call, which is why I've elected to extend a component to handle the reopening /dragdrop, etc). Best I can tell I've got working great, vice one issue that I just can't seem to resolve. Essentially, the first time the component loads it shows the nodes in the tree at an apparently random height that is significantly taller than what my normal tree node height should be. It would appear that the nodes are being spaced evenly across an arbitrary height of the tree which is greater in height than the 100% I've specified for the tree to take up inside it's container. I've included a screenshot of the behavior here, the left-hand image is the initial, jacked up state, and the right-hand image is the very same component instance after the contents are loaded the second time: http://www.2b-studios.com/xmlTreeView_Problem.png http://www.2b-studios.com/xmlTreeView_Problem.png Any help you guys might be able to provide would be so very much appreciated, I've been beating my head against the wall on this for hours now.

RE: [flexcoders] Re: Async Concurrent Requests with AMF for BlazeDS or LCDS
Right, only for AMF, and I'm not aware of any documentation on that. If there was, it would be regarding NetConnection.call(...). URLLoader doesn't do any batching - it just hands off HTTP requests to the browser to send. But when using URLLoader, you need to be aware that browsers impose connection limits to a single domain (a recommendation in the HTTP 1.1 spec) so even there you end up in a pseudo-serial situation with no direct control over whether requests will be sent serially or concurrently. You can use CNAME hacks to circumvent this (ie. Yahoo/Google maps downloading map tiles), but that's quite a bit more complex to configure and deploy and your app needs to be hardcoded to know about all your CNAMEs and to know when to use which for what calls. Our HTTPChannel, which uses URLLoader internally, serializes the requests it sends to sync up with the behavior of the AMFChannel and RTMPChannel and try to ensure that requests from the client to the server have a consistent, expected order (very important for Data Management).

[flexcoders] Issue with PopupButton in full screen
Hi, I have an issue with popup button in full screen. I have a horizontalList in the popup window of the popup button. In Normal Screen mode the popup window comes up. But in Full Screen mode, the popup window doesn't turnup. Once u came from full screen mode to normal mode..even then the popup window doesn't show up. I am using stage.fullScreenWidth and stage.fullScreenHeight for changing the bounds of my application.( basically a flv player). But when I use stage.width and stage.height for changing the bounds, everything works fine. The popup window shows when u click on the popup button. I just want to know the difference between stage.width, stage.height and stage.fullScreenWidth and stage.fullScreenHeight...and why is it not able to show popup window when I use fullScreenWidth, fullScreenHeight. Please help... The player is at... http://tekkies.premapix.com/rambabu/flvplayer/MyVideoPlayer.html Thanks, Sudha.

[flexcoders] Re: Question regarding DataGrid
Hi Kenny,
Just for a little more background info that others may find beneficial.
You can think of the data object as a single record (or row) in the
DataGrid's dataProvider (dataset). Every column's itemRenderer in a
DataGrid has access to all of the fields in the record (data object);
regardless of the dataField that is set. However, since itemRenderers
are recycled, you have to perform any conditional logic in the
itemRenderer's set data function. This ensures that when the data is
changed, that the itemRenderer will be refreshed with the appropriate
state. Inside the RollOverButton itemRenderer, you'll have to override
the set data method in script:
override public function set data(value:Object):void
{
super.data = value;
if (data != null)
{
this.visible = (data.fn == showMe ? true : false);
}
super.invalidateDisplayList();
}
Hope that this helps.
Cheers,
-TH

[flexcoders] Automation libraries kill my app
I'm trying to use FunFX(http://funfx.rubyforge.org/) to do some automated testing of our GUI. I noticed that after I add the automation libraries to the compiler options of my main project, I can no longer interact with various parts of the UI using the mouse. This includes textinput, textarea, buttons, numericstepper, etc. I can tab to these controls, but I can not click on them to bring focus to it. Very odd. I've added the libraries in the main project's Additional Compiler Arguments property under Flex Compiler like so: -include-libraries C:\flex-sdk\frameworks\libs\automation.swc C:\flex-sdk\frameworks\libs\automation_agent.swc Any thought?

[flexcoders] CSS inheritance?
I'm trying to find a cleaner way of doing css. Right now I have a common border style used frequently throughout my app, and a couple common container styles (background, padding, width, etc.). I'd like a way to have the different container styles reference the border style, instead of duplicating those values. Does anyone know if there's a good way to do this in flex's limited css? Right now I'm just trying to find the least common denominators and split those out to separate classes. Thanks!

[flexcoders] Help me understand how to manipulate dataProviders
After doing some research which consisted mainly of searching through
this forum, I noticed a mantra along the lines of manipulate the
dataProvider, not the controls it populates. It makes sense,
especially since without directly manipulating the primary key of the
very first entry in a database , it will read as 1, while the first
index of a dataGrid will read as 0. Right now, I have a mostly
finished AIR form which serves as a way of maintaining a product
table. The dataGrid's provider is an array collection built from the
results of a select statement. To get to the point I'd like some
assistance in streamlining some things to not onlt help this form, but
others in the application which will use the same data access
functionality. For starters, here's how I update data:
Assume that the first primary key in the very first entry of the
database has been edited to read as 0 after it was entered so it syncs
up with the dataGrid.selectedIndex property.
//Begins the proceedure to edit a currently existing item when the
edit button is clicked
public function newEdit():void
{
chosenMode = Edit;
currentState = Edit Item;
editColumn.visible = false;
deleteColumn.visible = false;
duplicateColumn.visible = false;
this.lblUniqueID.visible = false;
this.rbAll.visible = false;
this.rbBillable.visible = false;
this.rbNonBillable.visible = false;
try
{
var selectedItemIndex:int = adgProducts.selectedIndex;
//Uses another select statement to get the needed information and
passes the results into
//variables which populates the controls instead of an arrayCollection
dataManager.selectProdDataForEdit(selectedItemIndex);
this.lblUniqueID.text = model.editVarOne;
this.txtNewProductID.text = model.editVarTwo;
this.txtNewProductName.text = model.editVarThree;
this.txtNewBarcode.text = model.editVarFour;
this.txtNewUnit.text = model.editVarFive;
this.txtNewQuantity.text = model.editVarSix;
this.txtNewVendor.text = model.editVarSeven;
this.txtNewCost.text = model.editVarEight;
this.txtNewList.text = model.editVarNine;
this.chkNewBillable.selected = model.editVarBool;
this.lblCurrentStatus.text = Currently + model.editVarEleven;
}
catch(ex:Error)
{
trace(ex.toString());
trace(ex.getStackTrace());
}
}
private function saveItem(mode:String):void//Differentiates between
whether you want to insert a new item or edit an existing one
{
switch(mode)
{
case Add_New: insertNew();
break;
case Edit: editItem();
break;
default: Alert.show(Cannot Determine State,State Unknown)
break;
}
}
//Actually edits an existing item when the save button is clicked
private function editItem():void
{//Takes the information from the controls and sets them equal to
global variables of the same type which
//are then passed into the function which performs the update
model.insertStringOne = this.txtNewProductID.text;
model.insertStringTwo = this.txtNewProductName.text;
model.insertStringThree = this.txtNewBarcode.text;
model.insertStringFour = this.txtNewVendor.text;
model.insertIntOne = parseInt(this.txtNewUnit.text);
model.insertIntTwo = parseInt(this.txtNewQuantity.text);
model.insertNumberOne = Number(this.txtNewCost.text);
model.insertNumberTwo = Number(this.txtNewList.text);
model.insertStringFive = this.cmbNewClass.selectedItem.toString();
model.insertBooleanOne = this.chkNewBillable.selected;
model.insertStringSix = this.cmbStatus.selectedLabel.toString();
model.insertIntThree = parseInt(this.lblUniqueID.text);
dataManager.updateProduct(model.insertStringOne,
model.insertStringTwo, model.insertStringThree, model.insertIntOne,
model.insertIntTwo, model.insertStringFour, model.insertNumberOne,
model.insertNumberTwo, model.insertStringFive,
model.insertBooleanOne, model.insertStringSix, model.insertNewDate,
model.insertIntThree);
cancelOperation();
//Refreshes the datagrid
refreshGrid();
}
What I want is to see if there's an easier way to do this via
accessing the ArrayCollection model.prodMaintData to get the values to
edit as opposed to going through another select statement as well as
some other things that might help. I don't totally understand the
functions associated with the ArrayCollection or at least what needs
to be passed into them to get what I need. Thanks in advance.

itemRenderers
are recycled, you have to perform any conditional logic in the
itemRenderer's set data function. This ensures that when the
data is
changed, that the itemRenderer will be refreshed with the
appropriate
state. Inside the RollOverButton itemRenderer, you'll have to
override
the set data method in script:
override public function set data(value:Object):void
{
super.data = value;
if (data != null)
{
this.visible = (data.fn == showMe ? true : false);
}
super.invalidateDisplayList();
}
Hope that this helps.

I have read about the render handlers not keeping state, but
I'm not

you've instructed? I'm sure I've seen it somewhere before, but

RE: [flexcoders] Help me understand how to manipulate dataProviders
Let me say this again, very clearly: Do not use the index of the
datagrid to identify records in the database.
Suppose someone deletes record 3 from the DB? The keys will then be
0,1,2,4,5... When you put that in a data grid you will have:
Key DGIndex
0 0
1 1
2 2
4 3 WRONG!
5 4 WRONG!
Also if the data gets sorted, you are totally screwed.
Instead, use the key propertry itself. Make sure it is in the data
query you use to retrieve the data, and it will be in the selectedItem
object.
var selectedItemKEY:int = adgProducts.selectedItem.KEY;
dataManager.selectProdDataForEdit(selectedItemKEY);
But first, what does selectProdDataForEdit() do?

Subject: [flexcoders] Help me understand how to manipulate dataProviders
After doing some research which consisted mainly of searching through
this forum, I noticed a mantra along the lines of manipulate the
dataProvider, not the controls it populates. It makes sense,
especially since without directly manipulating the primary key of the
very first entry in a database , it will read as 1, while the first
index of a dataGrid will read as 0. Right now, I have a mostly
finished AIR form which serves as a way of maintaining a product
table. The dataGrid's provider is an array collection built from the
results of a select statement. To get to the point I'd like some
assistance in streamlining some things to not onlt help this form, but
others in the application which will use the same data access
functionality. For starters, here's how I update data:
Assume that the first primary key in the very first entry of the
database has been edited to read as 0 after it was entered so it syncs
up with the dataGrid.selectedIndex property.

edit button is clicked

this.rbBillable.visible = false;
this.rbNonBillable.visible = false;
try
{
var selectedItemIndex:int = adgProducts.selectedIndex;
//Uses another select statement to get the needed information and
passes the results into
//variables which populates the controls instead of an arrayCollection

this.lblCurrentStatus.text = Currently + model.editVarEleven;

Do you control the server? Can you turn on verbose errors? That is in
the web.config file.
Can you debug the aspx page? Step through in Visual Studio to see where

If for some reason you can't do that, comment out all the code until you
get no error, uncomment a line,response.Write(here), hit the page in a
browser until you find where the error is.

Hi, Your problem is that you have both items in the dataProvider referenceing the same object. Remove private var authorObj:Object = new Object(); and add: var authorObj:Object = new Object(); right above: authorObj.name = author.name; This will create a new object for each node in the XML. -TH p.s. sounds very familiar to a previous post today. :-) --- In flexcoders@yahoogroups.com, flexawesome [EMAIL PROTECTED] wrote: I was trying to covert the XML file into ArracyCollection, but I had a problem for binding with DataGrid.

[flexcoders] Back Button issues . . .
Hi All,
I am having an issue with the ViewStack when the user clicks the back
button. The browser takes them back a page however, my Flex
application doesn't recognize the change thus none of my links work on
the previous page. Let me give an example as that sounds confusing.
The user is viewing a page in my application. Lets call it page one.
On page one the user clicks a link to go to page 2. Now the user is
viewing page 2 and clicks the back button to go back to page 1. For
some reason the link to page 2 no longer works. I found if the user is
viewing page 2 and clicks a button or link that use flex code to
navigate to Page 1, anything besides the back button, then the links
on page 2 will work. Below is some sample code of how I am working
with the ViewStack Links and Buttons . . .
Thanks for any help you can offer .. . ..

I am going to try to use the RSS PHP Proxy on this example...(below)
I am using the Flex3 code to load and parse the RSS files from the Flex3
documentation... it looks the same as most of the code from the
as3syndicationlib that is on Mike Chambers blog (also below). This PHP
proxy looks fairly simple to implement along with the most of the same
code that I am using now, it skips ASP as a proxy, which I thought would
be the easiest route, but I am not finding a way to use ASP for RSS XML
proxy that has been done and can be easily re-produced and I do not want
to invent a new version of the wheel or in this case a new version of
the Toyota Prius ...

Is there a way to set the scale of a component without triggering invalidateSize() ? My initial effort to create a ScaleToFit component involved setting scaleX and scaleY in updateDisplayList. But that results in some recursion. Perhaps this is the wrong place to set the scale. I notice that SWFLoader uses a DisplayObject as a content holder, but my attempts to cast this to DisplayObject before setting the property didn't help - the UIComponent version of set scaleX is still invoked.

[flexcoders] AIR capabilities
Hey guys, Apologies if this is an FAQ but I can't seem to find straight answers via google. I'm about to start work on an app, and I'd prefer to use AIR over Swing or JavaFX - I'm just wondering exactly what capabilities you get on top of Flex with AIR besides file read/write. Specifically, a few of the following things: - Can I get http response bodies when I get a 500 from a remote server? - Can I make http requests other than GET and POST? - If not, can I open a socket? If I can't do any of that, are there plans to allow AIR apps to be Java with a Flex / Flash UI and some sort of nice communication layer between them? Is there a third party solution that does this? -J -- Therefore, send not to know For whom the bell tolls. It tolls for thee. :: Josh 'G-Funk' McDonald :: 0437 221 380 :: [EMAIL PROTECTED]

If there was, it would be regarding NetConnection.call(...). URLLoader doesn't do any batching - it just hands off HTTP requests to the browser to send. But when using URLLoader, you need to be aware that browsers impose connection limits to a single domain (a recommendation in the HTTP 1.1 spec) so even there you end up in a pseudo-serial situation with no direct control over whether requests will be sent serially or concurrently. You can use CNAME hacks to circumvent this (ie. Yahoo/Google maps downloading map tiles), but that's quite a bit more complex to configure and deploy and your app needs to be hardcoded to know about all your CNAMEs and to know when to use which for what calls. Our HTTPChannel, which uses URLLoader internally, serializes the requests it sends to sync up with the behavior of the AMFChannel and RTMPChannel and try to ensure that requests from the client to the server have a consistent, expected order (very important for Data Management).

In order to have calls processed concurrently on the server, they need to arrive as separate requests. In the case of AMF, if you make a series of calls quickly chances are good/excellent that the Player will batch them up and send them to the server in the body of a single HTTP POST. When this happens, the server must unpack them and process them serially and then pack the results for all these calls back up in the body of a single HTTP response. Because we're dealing with a single request and response, there's no way to send back results for individual calls separately. When these results get back to the browser and are passed back into the Player, they are dispatched to your ActionScript handling code as asynchronous events. There's not a good way to force calls to be sent as separate requests, and even if you could, browsers impose limits on the number of concurrent connections they'll open to a server, so this really isn't the right way to solve your scenario. Also, in the case of RTMP all traffic between the client and server happens over a single connection and is ordered serially. If you want to process calls/messages/data asynchronously on the server the proper way, it requires a bit of work on your part to accomplish at this point. Rather than running your current logic in your RemoteObject directly when it is invoked, you need to break that out into a Runnable class, and when you're invoked, create an instance of this class that packages up the incoming args and info about the client making the call and then submit that for asynchronous execution to a java.util.concurrent.Executor that you'd need to set up during server startup. Your remoting method could return a job id or just void once it has queued an instance of your Runnable with the Executor. On the client when you get a ResultEvent for your call you don't get the actual result - you just know that your invocation was successfully queued for asynchronous execution on the server. So the second half of the equation is how to get the result or fault generated when the Executor runs your Runnable back to the client. You need to take advantage of messaging in BlazeDS or LCDS to achieve this. In your client app, create a Consumer and subscribe to a destination you define that you can publish results/faults as AsyncMessages back to target clients from your Runnable. Your Consumer should subscribe to a subtopic that applies only to it, or use a selector expression. When your Runnable runs and generates the result or fault to return, you'd can create an AsyncMessage containing the result of fault info and publish it to this destination, using either a subtopic header, or some other message header that will be evaluated against the Consumer's selector expression such that the message is routed to the proper Consumer. That lets you return async results or faults to clients in a truly asynchronous manner. This is actually something I'd like to see us bake into
