[flexcoders] Combobox text does not render on some

2008-12-11 Thread darylgmyers

I have form window with about 20 combobox fields.  Each one is bound to 
a unique arraycollection which is bindable.  When the window is first 
displayed there are 3 of the combobox firlds that do not display the 
text from the drop down list even though the value has been loaded 
correctly.  As soon as I click on one of them, they all display 
correctly.  From that point on while using the window they all work 
correctly as well.

Re: [flexcoders] Re: e4x Strings?

 The only way I could make this work is using an external 3rd party
 library. I am using http://code.google.com/p/xpath-as3. It works but
 is noticeably slow on datasets exceeding 1000 rows.

Sorry to hijack this.. but if you have specific use-cases which you
think should perform better, could you post them to the xpath-as3

Subject: RE: [flexcoders] Change Timezone

Pratik, 
 
 I would like to know if there is any way to dynamically change the
 timezone in flex.
 
Not literally, no. 
 
 Say suppose we have local time and few check boxes to see time in
 other timezones. When you check and uncheck the check box the time
 changes according to the selected timezone. This would not depend on
 the location of the persons timezone. So persons local timezone may be
 PST but he wants to see the data in EST.
 
To calculate the time elsewhere you have to factor-in the local machine's
timezone offset value. 
I worked out the following for my World Clock last year:  

snip 
// Local Time 
var lDate:Date = new Date(); 
// Elsewhere Time 
var utcH:Number = -8;// New York: EST 
var utcM:Number = 0; 
var wDate:Date = new Date(lDate.getTime() + (lDate.getTimezoneOffset() *
1000 * 60) + (utcH * 1000 * 60 * 60) + (utcM * 1000 * 60)); 
trace(wDate = +wDate); 
/snip 
 
Note: 
The GMT value in the trace will still reflect the local machine's timezone.
Just ignore it. The important data are the time and date. 

Going forward you will want to consider the issues presented by Daylight
Saving Time: 
Does the locale of the local machine observe DST? 
Is the locale of the local machine currently in DST? 
Do they observe DST in the designated Elsewhere? 
Is the designated Elsewhere currently in DST?

[flexcoders] Re: Cannot Tab to MovieClips from Flash SWF Loaded with SWFLoader

2008-12-11 Thread aut0poietic

Repost:  Sent similar reply yesterday, but it didn't make it here for
some reason.

Alex, serious thanks for your help. 

I got the problem solved a different way, but you pointing me at the
IFocus* classes provided it. 

Basically, I rolled my own FocusManager to be a sort of Hybrid -- it
functions normally most of the time, but it's addFocusables() method
was altered to be public and to have specific methodology for handling
UIMovieClip classes originating in an SWFLoader. 

In the main MXML file I removed and deactivated the default
FocusManager from the application and the systemmanager, Inserted mine
in both places, and activated it.

I also had to roll my own UIMovieClip class and downloaded the source
to the Flex Component Kit classes to do it. I then wrote a bit of JSFL
that adds my custom UIMovieClip class as the Base Class for all MC's
in the Library. 

I also subclassed the SWFLoader to pull MovieClips from the loaded SWF
(based on their AccessibilityProperties) and add them to my
FocusManager on onLoad, and remove them onUnload. 

So far so good. It's going to take a ton of tweaking to get the Flash
to behave similarly to the Flex controls -- and I haven't even
partially addressed the accessibility yet. 

Thanks for the point in the right direction!

In the example code there is...

setClosePolicyForTab(0, SuperTab.CLOSE_NEVER);

There is also...

// Always Show Close Button
setClosePolicyForTab(0, SuperTab.CLOSE_ALWAYS); 

and...

// Only Show Close Button on Currently Selected Tab
setClosePolicyForTab(0, SuperTab.CLOSE_SELECTED);

 I hadn't really looked into the ASyncToken until now. However, for

 The calling code doesn't need to know about it. 

Right.  The calling code doesn't need to do anything different.  The 
change is inside your method.

Here's an example:

/*  Execute method.  If calling object passes in result and fault 
handlers,
those are used.  Otherwise, the defaults are 
used.   */
public static function execute(categoryID:int=-1, 
searchString:String=null, 
resultHandler:Function=null, 
faultHandler:Function=null):void{
if (_channels.channels.length==0) {
throw new Error('No endpoint 
specified for GetCategories command Remote Object');
}
//set up remote object
_ro.channelSet=_channels;
_ro.destination = 'AMF_Category';
_ro.source = 'AMF_Category';
//set up a token so we can tell the result of 
this call from other calls
var token:AsyncToken=_ro.getServicesCount
(categoryID-1?categoryID: null, searchString);
//assign the result and fault handlers from 
the calling object
token.addResponder(new Responder(!
(resultHandler==null)?resultHandler:countLoaded, 
!
(faultHandler==null)? faultHandler: loadFailed));
}
/*  trace out the return since we don't know 
where to put it */
private static function countLoaded
(e:ResultEvent):void{
trace(e.result.toString() + ' profiles');
}
private static function loadFailed(e:FaultEvent):void{
trace(e.fault);
}

 In my opinion this is neater
 than something like:
 
 var asyncToken:ASyncToken = save(xml);
 asyncToken.addResponder(...

Suit yourself.  You weren't satisfied with what you were using.  I 
offered an alternative.
 
 Also, I don't like adding responders after the call has been made. 
I know it
 works, but still...

Me neither.  I'm not sure why they built it this way, but 
unfortunately that's what we have.  Just don't dispatch an event in 
between LOL.

 Maybe I should start a new topic for this next question, but...
 
 ...in my implementation, I create a new HTTPService for each call. 
Any ideas
 how (in)efficient this is?  

I'm thinking it's pretty bad.

 As you can imagine, it keeps the implementation
 much simpler. No need for the ASyncToken. Just add new listeners 
each time a
 call is made. Everything is garbage collected. Oh, hang on, 
what keeps a
 reference to the HTTPService?

Good question.  What did you do with all the old eventListeners you 
were complaining about in your original post?

[flexcoders] can you truncate a multiline TextArea?

2008-12-11 Thread blc187

does anyone know of an existing component that can truncate multiline 
text?

I'm looking to either use an already made one, or create my own 
multiline TextArea and be able to truncate when the textHeight reaches 
more than the set height of the component.

So far I haven't been able to get a correct height for it, I keep 
getting a much larger height than it actually is because the 
textHeight reflects the size of the htmlText, even though I'm only 
setting text, not htmlText on it.

Is there a way to get a more accurate textHeight?

RE: [flexcoders] Best practice for calling asynchronous functions?

I haven't been following this thread, but the sample code below can actually be 
shortened to something like this:

save(xml).addResponder(new AsyncResponder(handleResult, handleFault));

No AsyncToken in the code and rather than new'ing the responder, if you always 
want to direct results/faults to a consistent pair of handler functions you 
could set up the AsyncResponder earlier and just pass in a ref.

   save(xml).addResponder(saveResponder);

The only reason to actually get a ref to the returned AsyncToken is if you want 
to add some dynamic properties to it that will help drive your handling of the 
eventual async result/fault (the token - and any custom state you've tagged it 
with - is accessible within your result/fault callbacks when they execute).

But for scenarios like that where I want to hang onto some data from the call 
site, I often find it simpler to take advantage of the variable/scope capture 
that a closure provides by defining my result/fault callbacks as inline lambda 
functions rather than manually capturing state by copying a portion of it 
into properties of the AsyncToken. So something like:

save(xml).addResponder(new AsyncResponder(
  function(...   , // inline result 
handler function
  function(... // inline fault 
handler function
 ));

Rather than new'ing an HTTPService for every call you make and trying to manage 
adding/removing event listeners (which will prevent instances from being GC'ed) 
in your wrapper I'd recommend just following the first convention I list above 
for each call: someMethod(args).addResponder(new AsyncResponder(handleResult, 
handleFault));

Best,
Seth

I hadn't really looked into the ASyncToken until now. However, for me it

The calling code doesn't need to know about it. In my opinion this is neater

RE: [flexcoders] RE: services-config.xml: compc or just mxmlc?

 I think what I'm really asking is when does the services-config.xml
 metadata get baked into a .swf (or .swc)?

When you compile with mxmlc and -services, a subset of your config is baked in 
the swf. It looks like compc doesn't complain about a -services option, 
although the 'baked in' aspect of this is code-gen'ed into the generated Flex 
init code. I don't know whether any of that is generated for a swc, but feel 
free to give it a try. You could test by compiling a swc with -services, then 
building a swf (including this swc) without -services and checking for baked in 
config.

The baked in subset of config ends up living here at runtime: 
mx.messaging.config.ServerConfig#xml

If you change services-config.xml, you should recompile the artifact that it's 
baked into. Avoid compiling it into multiple artifacts. After changes to 
[RemoteClass]'s you should recompile the respective artifacts they live in.

With your componentization all being a compile time concern here, it seems to 
me like you could get this all to work. Good luck :)

Seth

Seth,

Thanks--this is really handy. But I think what I was asking is a little
simpler: there are no modules (in the Flex sense of the word) here. I'm
essentially just interested in building a main app and being able to
extend it after-the-fact with an add-on that gets compiled into a
single .swf application. That is:

main app:
src/index.mxml (the Application, but only a wrapper around Main.mxml)
src/Main.mxml (the actual brains of the app)
src/util1.as
src/util2.as
services-config.xml

gets compiled into
foo.swf (the default app)
*and (separately)
foo.swc (a library which includes all the classes compiled from the
above sources except index.mxml)

later on, someone else (with access to index.mxml, services-config.xml,
and foo.swc, but not the sources, wants to extend this):

extended version:
src/index.mxml (same as above, but now modified to reference
Extended.mxml)
src/Extended.mxml
src/util3.as
lib/foo.swc (from above)
services-config.xml (from above)

this gets compiled into
super-foo.swf (the extended app)

Suppose that the extended version does not even change
services-config.xml or add any objects with [RemoteAlias] metadata. Do I
need to reference services-config.xml when

(1) building the original foo.swc
(2) building the super-foo.swf
(3) both

?

And if I do extend services-config.xml or add new [RemoteAlias] objects
to the extended version, does the answer to the above change (obviously,
it has to be at least 2 or 3)?

I think what I'm really asking is when does the services-config.xml
metadata get baked into a .swf (or .swc)?

Hi Maciek,

I don't have any practical experience with attempting to compile service
config and associated classes into modules and I don't know whether
compc would support it or not, but based on some informal discussions
with Alex and Jeff I wouldn't recommend it.

The core issue is that AMF serialization mappings (client to server
class aliases) within Flash Player aren't scoped per module or even app
domain as loaded classes are - unfortunately they're scoped to a
security domain (broader scope). This means that if the root swf loads
two or more modules (each will be loaded in its own child
ApplicationDomain by default), where these modules bake in overlapping
sets of classes that use [RemoteClass] metadata things won't work. The
modules will effectively trample each other's registered class aliases
to point to their respective local classes. Say you have a class Foo
([RemoteClass(alias=com.Foo)]), that you've compiled into both
modules. You now have two separate class defs on the client (one per
module/sub app domain), but only one alias registered (scoped to the
security domain both of these app domains belong to). When the loosing
module receives a Foo off the network it will fail to deserialize
correctly because the alias mapping points to the class def in the other
module, which this module doesn't have access to.

I think the best approach for now is to place your service config and
all shared classes with [RemoteClass] metadata into your root swf, and
then expose this to your modules through a controlled API - say a
registry of network services or operations the modules can use. You may
be able to get away with keeping non-shared classes with [RemoteClass]
metadata in specific modules, but I haven't tried that.

Best,
Seth

[flexcoders] Error 2032, but only in IE with php session_start

2008-12-11 Thread Ramsey, Robert L

Hi,

I have an app that makes  http requests to a php script on the server.  If I 
have session_start() in the back end file so I can use session variables in 
php, I get the following error:

[RPC Fault faultString=HTTP request error faultCode=Server.Error.Request

faultDetail=Error: [IOErrorEvent type=ioError bubbles=false cancelable=false 
eventPhase=2 text=Error #2032].

URL: https://path.to/my/file.php;]

But only when I use Internet Explorer.  If I use Firefox, it all works 
beautifully.

If I rem out the session_start() line in the php script it works fine, so I can 
confirm that that is the line that is causing the error.  Has anyone seen this?

Here's my goal.  I have an app that plays videos and users aren't supposed to 
be able to download the video easily.  The very popular firefox plugin Video 
DownloadHelper can see the mp4 files (but not the flv files for some reason) 
and download them.  I use a php file to read the contents of the videos from a 
non-web accessible folder.  I want to use mp4.  What I did was to set a php 
session variable when the user selects the file from the combobox, then 
immediately fetch the video.  Right before it sends the video the php file 
unsets the session variable.  This means that the user has to use my combobox 
to see the file, because it is the only thing that can set the session variable 
and the variable is destroyed as the file is sent.

This is only meant to stop casual copying.  Our faculty is aware that there's 
always a way to capture the video.

Any ideas?

Thanks,

Bob

RE: [flexcoders] LCDS - Handling client disconnection on the server

2008-12-11 Thread Jeff Vroom

When you unplug the network cable the client may not get a disconnect event 
from the networking layer until it tries to use that connection to send a 
request to the server.You might need a heartbeat ping which runs 
periodically to test the connection to force that close event.

Also, if you are on 2.5.1 you might need a hotfix as there was a bug where a 
client who disconnects, then reconnects again immediately before the session 
expires was not getting resubscribed properly.That is fixed in 2.6 and 
2.6.1.

Re: [flexcoders] can you truncate a multiline TextArea?

I would suggest extending the class by adding a property numLines to the
textarea - that property would take its value from the textField.numLines,
which is a protected property inside TextArea that represents the actual
textField used to render text. Then you can call TextArea.getLineMetrics()
and multiply it by the number of lines you got from numLines;

This is just from the top of my head but this looks like a good solution to
me.

Funny.   I didn't realize we were talking about iterating arrays with for..in 
until just now.  I don't think we do that in Flex code.  If the docs say arrays 
will iterate via for..in in index order then I'd probably trust that, 
especially if you stuff your arrays in index order

Could you clarify this? Does this non-guarantee apply to numerically indexed 
arrays and ArrayCollections too? Or just to associative arrays and object 
properties?

The docs imply that the order is maintained by for...in with numerically 
indexed arrays. It would be a big change if that were not the case.

[flexcoders] Re: Error 2032, but only in IE with php session_start

I use session_start() in my PHP files and it works fine (Although I
use Remoting).

Perhaps there is something else causing the problem that is masked by
the removal of the session_start() ?

To do what you want, could you perhaps use the referrer header? If the
referrer is not your SWF then don't send the file.

 Hi,

 But only when I use Internet Explorer.  If I use Firefox, it all
works beautifully.
 
 If I rem out the session_start() line in the php script it works
fine, so I can confirm that that is the line that is causing the

 Here's my goal.  I have an app that plays videos and users aren't
supposed to be able to download the video easily.  The very popular
firefox plugin Video DownloadHelper can see the mp4 files (but not the
flv files for some reason) and download them.  I use a php file to
read the contents of the videos from a non-web accessible folder.  I
want to use mp4.  What I did was to set a php session variable when
the user selects the file from the combobox, then immediately fetch
the video.  Right before it sends the video the php file unsets the
session variable.  This means that the user has to use my combobox to
see the file, because it is the only thing that can set the session
variable and the variable is destroyed as the file is sent.
 
 This is only meant to stop casual copying.  Our faculty is aware
that there's always a way to capture the video.
 
 Any ideas?

[flexcoders] ComboBox SelectedItem Problem with resultFormat e4x - Very Urgent

2008-12-11 Thread samsonkiran


Hi

I have an Flex file (.mxml) in which i am making the HTTPService call to one
JSP. This JSP returns me an XML data. I need to populate the comboBox in the
FLEX with the data coming from the JSP in XML format.  This is the sample
code.

test.mxml

?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; width=100%
height=100% backgroundColor=#FF creationComplete=srv.send()
layout=absolute
mx:HTTPService id=srv url=../test/test.jsp resultFormat=e4x result =
resultHandler(event) fault=faultHandler(event) method=POST
/mx:HTTPService
mx:ComboBox id=comboBox  width=200 labelField=@label
dataProvider={srv.lastResult.company} change=changed()/
/mx:Application
mx:Script
   ![CDATA[
import mx.controls.Alert;
private function resultHandler(event:Event):void{
Alert.show(In Result);

private function faultHandler(event:Event):void{
   Alert.show(event.toString());
  
}
}

private function changed():void{
Alert.show(comboBox.selectedItem.data);
}
]]
/mx:Script

XML Input from JSP:
?xml version=1.0 encoding=utf-8?
response
company data=c1 label=company1/
company data=c2 label=company2/
/response

I am able to populate the comboBox with the data coming from the JSP. But
the problem is comboBox.selectedItem.data is not giving me any value. It
should give me c1 if the company1 and c2 if company2 is selected.
But it does not give me any value.

comboBox.selectedItem.label works fine. But i need
comboBox.selectedItem.data for my requirement. Any idea why is this not
working.

At the same if i remove the resultFormat e4x attribute (i.e working with
default resultFormat of Object), i am able to retrieved the selected value
using comboBox.selectedItem.data. Ofcourse the code is modified as below
since the format of response data is different.


mx:HTTPService id=srv url=../test/test.jsp result =
resultHandler(event) fault=faultHandler(event) method=POST
/mx:HTTPService
mx:ComboBox id=comboBox  width=200 labelField=label
dataProvider={srv.lastResult.response.company} change=changed()/

Please let me know why this selectedItem.data is failing when i use e4x
resultFormat. Am i missing out anything? This is very urgent.

Thanks in advance

$Config = array();
//authorisation URL
$Config[authURL] = authUrl;
$Config[DocumentID] = DocumentID;
$Config[Data] = fopen(Doc.pdf);

now I need to serialize it to AMF formatted object and save it as

In the end I need to be able to load it inside Flex with simple
URLLoader and get it back with loader data
var Config:Object = new Object ();

so anything like AMF.serialize in amfphp/zend or simmilar?

I realize that I can implement ITreeDataDescriptor and use getChildren() to

fire an event 
to the tree? If so, which one?

[flexcoders] MXML Components and measure()

2008-12-11 Thread Michael Prescott

When is it that you have to implement measure()?  If you're building
components in MXML, purely out of other standard Flex components, do you
ever need to bother with measure()?

I'm making an MXML item renderer, and I'm running into some trouble with the
DataGrid handling the variable row height - particularly once I put this
into my renderer:

mx:Text htmlText={*some HTML from somewhere*}/

Coming at this rather naively, it seems that the VBox that the Text each
ought to have appropriate measure() implementations already, but clearly
something's gone wrong.

Any tips would be helpful.

Re: [flexcoders] Re: speed of the for each looping

I've spent a lot of time poking around inside the collections stack (it's

order for for each..in over indexed looping at the moment (Fx 3). That could
of course change without notice, but for now I think that where speed isn't
important, you can safely pick the one that produces the prettier or more
comprehensible code :)

 Could you clarify this? Does this non-guarantee apply to numerically
 indexed arrays and ArrayCollections too? Or just to associative arrays and
 object properties?



 The docs imply that the order is maintained by for...in with numerically
 indexed arrays. It would be a big change if that were not the case.

[flexcoders] runtime class type reference?

2008-12-11 Thread Maciek Sakrejda

Is there a way to get a reference to the runtime type of an AS3 object?
Something like Foo.class in Java? I think I can do

var mysteryObjClass:Class =
getDefinitionByName(getClassInfo(mysteryObj).name);

but this strikes me as a rather roundabout way of doing it.

Re: [flexcoders] Best practice for calling asynchronous functions?

Some quick pointers (I do the framework stuff where I work):

All (afaik) network requests are queued up until the end of frame, so you
can nearly always add responders to a token...

...Except request errors, such as an invalid SOAP request. These can in some
circumstances generate Fault exceptions that never make it to the token :(

Here's some example code:

// ...

//This code is to catch invocation problems, since Flash has
decided to interrupt the flow of the VM for
//FaultEvent rather than dispatch it on next frame from the
token
operation.addEventListener(FaultEvent.FAULT,
invocationFaultHandler);

//Send the request
log.debug(Sending request...);
token = operation.send();
log.debug(...Send attempt completed);

//Remove our invocation fault listener
operation.removeEventListener(FaultEvent.FAULT,
invocationFaultHandler);

//Do we need to send this info on to the token's listeners in a
frame or two?
if (invocationFaultEvent) //Instance-level global
{
log.debug(There was an invoke error, which means the token
listeners aren't notified. Will redispatch to them in 250ms);
//When we create the timer, we're using a hard listener
reference because this helper instance may otherwise be collected before
we're done!
//So make sure to remove the handler (and kill the timer) on
firing!
timer = new Timer(250, 1);
timer.addEventListener(TimerEvent.TIMER,
reDispatchInvocationFault);
timer.start();
}

return token;
}

private function invocationFaultHandler(event : FaultEvent) : void
{
log.error(A fault occured during invocation);
this.invocationFaultEvent = event;
}

private function reDispatchInvocationFault(event : TimerEvent) :
void
{
//Important!
timer.removeEventListener(TimerEvent.TIMER,
reDispatchInvocationFault);
timer.stop();
timer = null;

token.mx_internal::applyFault(invocationFaultEvent);
}

 I haven't been following this thread, but the sample code below can

 No AsyncToken in the code and rather than new'ing the responder, if you
 always want to direct results/faults to a consistent pair of handler
 functions you could set up the AsyncResponder earlier and just pass in a
 ref.

   save(xml).addResponder(saveResponder);

 The only reason to actually get a ref to the returned AsyncToken is if you
 want to add some dynamic properties to it that will help drive your handling
 of the eventual async result/fault (the token - and any custom state you've
 tagged it with - is accessible within your result/fault callbacks when they
 execute).

 But for scenarios like that where I want to hang onto some data from the
 call site, I often find it simpler to take advantage of the variable/scope
 capture that a closure provides by defining my result/fault callbacks as
 inline lambda functions rather than manually capturing state by copying a
 portion of it into properties of the AsyncToken. So something like:

save(xml).addResponder(new AsyncResponder(
  function(...   , // inline
 result handler function
  function(... // inline
 fault handler function
 ));

 Rather than new'ing an HTTPService for every call you make and trying to
 manage adding/removing event listeners (which will prevent instances from
 being GC'ed) in your wrapper I'd recommend just following the first
 convention I list above for each call: someMethod(args).addResponder(new
 AsyncResponder(handleResult, handleFault));

 Thanks for all the responses.

 I hadn't really looked into the ASyncToken until now. However, for me it

 the, for example, save(XML, Function, Function) method.

 The calling code doesn't need to know about it. In my opinion this is

Re: [flexcoders] Best practice for calling asynchronous functions?

Hi Seth,

It stems I think from the fact that the Async stuff in the SDK (AsyncToken,
IResponder impls) are a little too closely tied to Flex's underlying
remoting stuff. But I've already brought that up on the SDK dev list and it
seemed you guys are on top of that issue.

The problem is that from the SDK's point of view, there is no request.
There's no IMessage, there's nothing to wait on. However from the
application's point of view, there is.

If I'm going to go to the trouble of building a failing case and submitting
a bug, I may as well include a patch. SOAPEncoder throws an exception when
asked to build an incorrect request which is reasonable, but of course this
happens before the token is returned to the application code, and the event
is sent to the Operation (and WebService I assume) before the application
gets a chance to register its interest.

Is there a place in the SDK code where a non-visual component needs to do a
callLater() that I can copy? Do they just use the old new Timer(1,1)
trick?

 I haven't been following this thread, but the sample code below can

 No AsyncToken in the code and rather than new'ing the responder, if you
 always want to direct results/faults to a consistent pair of handler
 functions you could set up the AsyncResponder earlier and just pass in a
 ref.

  save(xml).addResponder(saveResponder);

 The only reason to actually get a ref to the returned AsyncToken is if you
 want to add some dynamic properties to it that will help drive your handling
 of the eventual async result/fault (the token - and any custom state you've
 tagged it with - is accessible within your result/fault callbacks when they
 execute).

 But for scenarios like that where I want to hang onto some data from the
 call site, I often find it simpler to take advantage of the variable/scope
 capture that a closure provides by defining my result/fault callbacks as
 inline lambda

Re: [flexcoders] runtime class type reference?

There are other cool utils around that do introspection, but here's mine:

 That's too bad--with classes as first-class objects, it's pretty sexy to
 be able to do something like

 var someClass:Class = getDefinitionByName(com.truviso.SomeClass);

 instead of having to lather on the syntax like in Java. It'd be nice to
 do more stuff along those lines. Thanks anyway, Alex.

 There isn't much introspection APIs in AS.  I'd use
 getQualifiedClassName instead of getClassInfo.  getClassInfo can be
 expensive

 Is there a way to get a reference to the runtime type of an AS3 object?
 Something like Foo.class in Java? I think I can do

 var mysteryObjClass:Class =
 getDefinitionByName(getClassInfo(mysteryObj).name);

 but this strikes me as a rather roundabout way of doing it.

[flexcoders] AS ResourceBundle Keys with Args?

2008-12-11 Thread securenetfreedom

I am creating ActionScript ResourceBundles.
Is possible to create a resource key/value via AS that allows arguments
like:

rb.content[DISTANCE_FORMAT] = {0} miles;

I am getting key/value pairs from a database so I will be creating the
RBs at runtime. So will be looping thru the result set with something
like:

rb.content[record[i].key] = {0} record[i].value;

Thanks,

Jeff

[flexcoders] Maintaining scale when resizing embed tag

2008-12-11 Thread ivo

Hello listers,

I have a Flex App with scaleMode set to StageScaleMode.SHOW_ALL, the 
Application tag dimension set to 300x500 and it scaled perfectly when modifying 
the dimensions of the embed tag.

To make things cleaner I removed all the AS3 code from the Application MXML 
file and placed it in an AS3 class that extends Application (BaseApp.as). I 
then updated the MXML file to have base:BaseApp xmlns:base=*  as the root 
tag with dimension still at 300x500. Now I find that the scale mode is not 
preserved correctly when modifying the dimensions of the embed tag. The UI 
content in the MXML scales down way farther that the embed dimensions.

If I sized the embed tag at 150x250 I see the flash content takes up those 
dimensions but the visual content provided by the MXML subclass is scaled down 
to 90x120 .

If I move the dimensions from the MXML subclass to the base class then the 
content is scaled even further to like 45x75

Can anyone help me understand what is going on and how I can make the content 
scale correctly?

Thanks,

- Ivo

 Right.  The calling code doesn't need to do anything different.  The 
 change is inside your method.
 
 Here's an example:
 

Thanks for that - its roughly what I had in mind - but its good for me to
see an example.

 Suit yourself.  You weren't satisfied with what you were using.  I 
 offered an alternative.
 

Maybe I wasn't being clear. I just prefer to keep any ASyncToken code out of
the calling code. Having it inside the implementation is not a problem for
me (other than for the other problems with it discussed in this topic). So,
I don't see it as an alternative - its more of an implementation detail.


Amy-28 wrote:
 
 As you can imagine, it keeps the implementation
 much simpler. No need for the ASyncToken. Just add new listeners 
 each time a
 call is made. Everything is garbage collected. Oh, hang on, 
 what keeps a
 reference to the HTTPService?
 
 Good question.  What did you do with all the old eventListeners you 
 were complaining about in your original post?
 

My current implementation has something like:

function save(xml:XML, successFunc:Function, failureFunc:Function):void {
var service:HTTPService = new HTTPService();
...
service.addEventListener(ResultEvent.RESULT,
function(evt:ResultEvent):void {
trace(Successfully saved XML);
successFunc();
});
service.send(); // called after the event listeners have been added :)
}

That's it. The successFunc and failureFunc are only scoped to the calling
code's method and so should be garbage collected when the service is garbage
collected.

What I don't know is when the service is garbage collected? I'm assuming not
before the result or fault event is fired!

Wouldn't any problems before the async token is returned, be thrown as an
exception from the method returning the async token? Therefore the calling
code just needs to catch that exception and handle it.

The only problem with this would be if an event is generated after the async
token is returned and before the responder is added. This would only be an
issue in a multi-threaded environment.

Re: [flexcoders] Best practice for calling asynchronous functions?

SOAPEncoder throws an exception, which is caught by Operation, swallowed,
and then a fault event is dispatched from the Operation instance. If you do
all your async stuff using responders because you need to know *which*
action has just finished or faulted (among other things), you never get to
hear about it.
