I must be missing something simple here.  I'm reading in XML that looks like 
this:

?xml version=1.0 encoding=UTF-8?
REGISTRY
  REGISTRY_DECLARATION/
  REGISTRY_ENTRIES
Attribute
  AttributeNameAttr_1/AttributeName
/Attribute
Attribute
  AttributeNameAttr_2/AttributeName
/Attribute
Attribute
  AttributeNameAttr_3/AttributeName
/Attribute
  /REGISTRY_ENTRIES
/REGISTRY

I'm trying to get all Atribute nodes using the .. operator, but it always 
returns 0, even though xmlRoot looks fine.

protected function xmlService_resultHandler(event:ResultEvent):void
{
  if (event != null  event.result != null  event.result is XML) {
var xmlRoot:XML = event.result as XML;
if (xmlRoot  xmlRoot.length()  0) {
  var lst:XMLList = xmlRoot..Attribute;
  trace(lst length =  + lst.length());
}
  }
}

You shouldn't do a check on the length() for xmlRoot... that represents the
REGISTRY level... otherwise your code looks fine.

public class Test extends Sprite

public function Test()
{
if (xmlRoot  xmlRoot.length()  0) {
var lst:XMLList = xmlRoot..Attribute;
trace(lst length =  + lst.length());
}
}
}
}

it outputs 'lst length = 3' as expected.

I guess I should have copied the entire XML.

REGISTRY xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; 
xsi:schemaLocation=http://schemas.dell.com/wbem/biosattributeregistry/1 
file:///C:/work/12G/Attribute%20Registry/DCIM_AttributeRegistry.xsd

Turns out if I just remove the last namespace, 
xmlns=http://schemas.dell.com/wbem/biosattributeregistry/1;

Then it works correctly.

Any idea why this would cause it to not be able to find the children?

because the elements are then defined in the namespace 
http://schemas.dell.com/wbem/biosattributeregistry/1;. To access them
through e4x you have to create a corresponding namespace object, e.g.:

private namespace biosattributeregistry = 
http://schemas.dell.com/wbem/biosattributeregistry/1;;
use namespace biosattributeregistry;

[flexcoders] help with anonymous functions...

2011-09-22 Thread grimmwerks
OK I don't mean to make this a bit convoluted - but I guess the basics of the 
question is regarding using anonymous functions within a member class and being 
able to set variables within that member class.

The convoluted question is this:  I've got in my app an Interface class that 
has pointers to scala/java functions and are passed in callbacks like so:



function echoOrderEvent(callback:Function):void ;   

[UriParams(p1=correlationId)]
function echoOrderCacheEvent(callback:Function,extension:Object):void ;

 

Now in my class I create vars as functions for callbacks like so:

private var echoOrderCacheEvent:Function = function(jstr:String):void{
Alert.show(GOT ORDER EVENT );
}  

I set up the call back to this function as such:

interfaceClass.echoOrderCacheEvent(echoOrderCacheEvent, {correlationId: 
sessionId});   

 
Now, this works great except in the anonymous function I don't have any access 
to the public or private member vars of the class - only of course if I make 
the vars static, which is not what I want to do.

What I *can't* figure out is how to make the callback a regular member function 
such as:

public function echoEvent(str:String):void{
blah blah
}

And have that work with the interface class -- as 
interfaceClass.echoOrderCacheEvent(echoEvent, {correlationId: sessionId}) won't 
work; what I was thinking was perhaps .call or .apply methods but not sure how 
best to use them here...

Re: [flexcoders] Trying to pass a value to the mxml/swf file from java(android).How?

2011-09-22 Thread ganaraj p r
In order to pass values to a swf you have a concept called as flashVars.

If you come from a java / C background you would know that your main entry
point in there is the main() function. This main function can be called
without any arguments or with arguments..( if you are familiar with argc and
argv[] ). FlashVars is something similiar to that concept.

Just have a read about those and you should be able to get the proper
answers.

 HI,
 I have been trying to pass the values to the mxml file(whose output is .swf
 file) via android (java code) , But i am unable to do this.Here is my
 problem, I think tht .SWF file is a binary file(like exe , .out or .dll or
 .iso) which runs on flash platforms(browser, mobile phone supporting
 flash).Now i want the output of the .swf to be dependent on some values
 which I want to pass thourgh the android code.

 Other way is that I put the mxml files itself inside the eclipse(android
 project IDE) and pass the values to it (don't know how) compile it using
 mxmlc.exe compiler and link(don't know how ) with the android project and
 generate the final output file(we call it apk) and run it.Please suggest me
 which way to go even though my study is still partial but I am at the cross
 roads of confusion.Please suggest me which way to go and how.

I don’t know why passing in echoEvent wouldn’t work.  What error did you get?

Another options are to pass in a third parameter as the object for use in call 
or apply.

You can theoretically do this as well in the constructor of the class:
Public function MyClassConstructor()
{
var thisObject:Object = this;
echoOrderCacheEvent = function(jstr:String):void{
trace(thisObject);  // use ‘thisObject’ instead of ‘this’

I've tried the old pass through - but it's definitely not working properly; the 
'this' that's getting called within the function is NOT the function  - it's a

callback through the interface; something another dev has created and just want 
to come back with enough ammunition that the callbacks aren't being set

It seems to me that he's creating another anonymous function as part of the

Re: [flexcoders] help with anonymous functions...

2011-09-22 Thread Alex Harui
IMHO anonymous  functions are way more trouble than they are worth.  If I had 
the time, I would eliminate them from all framework code.

Looks from the stacktrace that someone is using apply() to change the this 
pointer.

Now in my class I create vars as functions for callbacks like so:

I set up the call back to this function as such:

interfaceClass.echoOrderCacheEvent(echoOrderCacheEvent, {correlationId:

Now, this works great except in the anonymous function I don't have any access 
to the public or private member vars of the class - only of course if I make 
the vars static, which is not what I want to do.

What I *can't* figure out is how to make the callback a regular member function 
such as:

public function echoEvent(str:String):void{
blah blah
}

And have that work with the interface class -- as 
interfaceClass.echoOrderCacheEvent(echoEvent, {correlationId: sessionId}) won't 
work; what I was thinking was perhaps .call or .apply methods but not sure how 
best to use them here...

Thanks  -- yeah it seems like the something's happening on the stomp / callback 
before it's getting to me.

Have another quickie about itemrenderers and factory properties, but going to 
ask on another thread.

 Another options are to pass in a third parameter as the object for use in

 You can theoretically do this as well in the constructor of the class:
 Public function MyClassConstructor()
 {
 var thisObject:Object = this;
 echoOrderCacheEvent = function(jstr:String):void{
 trace(thisObject);  // use ‘thisObject’ instead of ‘this’

[flexcoders] Is it possible to add Flex components to the Stage?

2011-09-22 Thread Hogs Haven
From everything I've read, Flex components can only be added to Flex 
Components (ie: VBox to Application, VGroup to Panel, etc)

I'm working in an AS3 view library (no Flex, just Sprites) where I need to add 
a Scrollable container component to the Stage on a click event. There's no way 
to do this as I see it unless I write my own Scroll container, use Flex SDK 
(don't think this works), or use fl.containers.ScrollPane (which is not an 
option since we're not using a .fla)

So basically, I'm trying to accomplish this, as simple runnable example, but it 
fails silently and nothing appears...any ideas? Thanks.

[flexcoders] ClassFactory, properties, itemrenderers and changing prop dynamically

2011-09-22 Thread grimmwerks
Here's another convoluted question -- I've got a list that is bound to an array 
of a certain Class - let's cal them Permissions.  In the Permissions class 
you've got userId, read and write (booleans there, id for userId, normal stuff).

I'm using the same itemrenderer in two lists - a source list which is not 
editable and a drop list which is;  the itemrenderer has an 'editable' variable 
and I'm setting each list's ClassFactory to this same itemrenderer, with one 
ClassFactory's properties setting editable to false, one to true.  All that is 
good.

Now the strange request I JUST had from someone here is that once an item is 
dragged and dropped from the source list to the drop list, the item in the 
source list should dim to show that it's already been chosen, unable to choose 
again.   I've created a property called itemEnabled in the itemrenderer, 
defaulting to true (so it's ignored in the droplist basically).

Here's the thing; it would be simple enough to set a particular item's 
'itemenabled' property in the dataproviider and it would trickle down; but 
since this is a list of cast objects that don't have the itemEnabled property 
it's a no go...

So is there a way of selecting an itemrenderer or item at a certain position in 
the sourcelist and setting IT's itemEnabled to false? Is it something with the 
classfactory for a specific item?

Re: [flexcoders] ClassFactory, properties, itemrenderers and changing prop dynamically

2011-09-22 Thread Alex Harui
Because renderers get recycled, it is not recommended to access a renderer 
instance and change properties on it.  There is a indexToItemRenderer() method, 
but I wouldn’t use it for this.

The recommended practice is an “associated list”, essentially a weak-reference 
dictionary or object map that stores additional information associated with the 
data objects (not the renderers).  In this case, I would probably use a 
dictionary and stuff each dropped object in the dictionary.  Each renderer will 
compare its data property to see if it is in the dictionary and set the 
itemEnabled accordingly.

Re: [flexcoders] ClassFactory, properties, itemrenderers and changing prop dynamically

2011-09-22 Thread Alex Harui
If it were me, I would subclass the List and add an “associatedList” property 
that references this map.

The logic for setting itemEnabled in the renderer is hopefully in an override 
of commitProperties.  I would override the data setter to call 
invalidateProperties.

Then in commitProperties, you can do something like:

{code}
var list:MyList = owner as MyList;
if (list) // will be null in the destination list since it is just a List 
and not a MyList
{
var map:Object = list.associatedList;
{code}

Because renderers get recycled, it is not recommended to access a renderer 
instance and change properties on it.  There is a indexToItemRenderer() method, 
but I wouldn’t use it for this.

The recommended practice is an “associated list”, essentially a weak-reference 
dictionary or object map that stores additional information associated with the 
data objects (not the renderers).  In this case, I would probably use a 
dictionary and stuff each dropped object in the dictionary.  Each renderer will 
compare its data property to see if it is in the dictionary and set the 
itemEnabled accordingly.

Here's another convoluted question -- I've got a list that is bound to an array 
of a certain Class - let's cal them Permissions.  In the Permissions class 
you've got userId, read and write (booleans there, id for userId, normal stuff).

I'm using the same itemrenderer in two lists - a source list which is not 
editable and a drop list which is;  the itemrenderer has an 'editable' variable 
and I'm setting each list's ClassFactory to this same itemrenderer, with one 
ClassFactory's properties setting editable to false, one to true.  All that is 
good.

Now the strange request I JUST had from someone here is that once an item is 
dragged and dropped from the source list to the drop list, the item in the 
source list should dim to show that it's already been chosen, unable to choose 
again.   I've created a property called itemEnabled in the itemrenderer,! 
defaulting to true (so it's ignored in the droplist basically).

Here's the thing; it would be simple enough to set a particular item's 
'itemenabled' property in the dataproviider and it would trickle down; but 
since this is a list of cast objects that don't have the itemEnabled property 
it's a no go...

So is there a way of selecting an itemrenderer or item at a certain position in 
the sourcelist and setting IT's itemEnabled to false? Is it something with the 
classfactory for a specific item?

[flexcoders] Re: Is it possible to add Flex components to the Stage?

2011-09-22 Thread Hogs Haven
Thanks Alex for the reply. Yea, with systemManager being a Flex component I 
guess I'm out of luck. OK, refactor time.

 Thanks, but flash.display.Stage is not a Flex component; therefore it only 
 has addChild(). addElement() is part of the spark Flex classes.

Re: [flexcoders] Is it possible to add Flex components to the Stage?

2011-09-22 Thread Jeffry Houser


 addElement is only defined in spark components; that will just throw a 
compile time error.


 I'm not sure why you want to add a Flex Component directly to the 
stage.  I suppose in theory you could; but that would bypass all the 
Flex Framework code to position and size the component.  You'd, in 
essence, need to write your own layout manager. that performs the same 
functionality as the Flex Layout manager.


 In the context of Flex; it probably isn't a good idea to access the 
stage directly.

[flexcoders] Re: Trying to pass a value to the mxml/swf file from java(android).How?

2011-09-22 Thread Shunmuga
you can pass the arguments to swf file by using Flashvars:
FlashVars=arg1=valarg2=val2

string htmlUrl = object width=\550\ height=\400\ param name=\movie\ 
value=\file:///android_asset/sample.swf\ embed 
src=\file:///android_asset/sample.swf\ FlashVars=arg1=valarg2=val2 
width=\550\ height=\400\ /embed/object;

In MXML file:

var flashVarsObj:Object = Application.application.parameters as Object;
arg1 = flashVarsObj.arg1;
arg2 = flashVarsObj.arg2;


Thanks, Rohini.

 HI, 
 I have been trying to pass the values to the mxml file(whose output is .swf 
 file) via android (java code) , But i am unable to do this.Here is my 
 problem, I think tht .SWF file is a binary file(like exe , .out or .dll or 
 .iso) which runs on flash platforms(browser, mobile phone supporting 
 flash).Now i want the output of the .swf to be dependent on some values which 
 I want to pass thourgh the android code.
 
 Other way is that I put the mxml files itself inside the eclipse(android 
 project IDE) and pass the values to it (don't know how) compile it using 
 mxmlc.exe compiler and link(don't know how ) with the android project and 
 generate the final output file(we call it apk) and run it.Please suggest me 
 which way to go even though my study is still partial but I am at the cross 
 roads of confusion.Please suggest me which way to go and how.

[flexcoders] Re: e4x help

2011-09-22 Thread DP
You're probably getting an e4x error on the first empty node (because Attribute 
doesn't exist there).

Try to avoid this issue by using the hasOwnAttribute function to make sure 
that Attribute actually exists in that node.  This probably isn't it, but 
it's close:

xmlRoot..(hasOwnAttribute(Attribute))

I'm not sure the above will work because we're not returning a specific level, 
but hopefully you get the idea.  Use the following URL for a great explanation 
of Advanced E4X:

http://joshblog.net/2007/06/29/getting-advanced-with-e4x/

Hope that helps...
