Jeff From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Alex Harui Sent: Friday, December 02, 2011 2:26 PM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] RE: AIR/Window/DataGrid Issue Basic implementations should be able to use MXML. For example, you cram a bunch of MXML in a mx:Module and load that in an mx:ModuleLoader and it just works. But it gets trickier when using popups. Usually you have to call PopUpManager from AS anyway and you can choose the moduleFactory to pass in. Is the Window and DataGrid in one MXML file? Maybe instead of calling new MyWindow() you can use moduleFactory.create(some.package.MyWindow) and that will get things going in the right direction. I suspect the DataGroups worked because they don't have skins or the skins were in the main app. The DataGrid's styles are probably in the same module SWF as the DataGrid. The problem is that if the DataGrid's moduleFactory is pointing at the main app, it won't find the styles in there.

RE: [flexcoders] flex2gateway error
It could very well be that your request response time is exceeding the default time out for Remote Objects, but I'm not sure about app not working *at all* after that. This can create the intermittent behavior you're seeing, depending on load or query response time from the app's database. In AIR this is a real problem because on windows, the request times out at 30 seconds no matter what you do. But you say you're running a Flex app so, you *should* be able to set the requestTimeout on your RemoteObject to a higher value and see a mitigation of the behavior. HTH.

They generally like non-Flex test cases so if you can conjure up a simple AS-only case with NetConnection and show that timeouts are not working, that might expedite things.

RE: [flexcoders] Vote For This Critiical RemoteObject bug
Kelly, valid point and I've already spent considerable time optimizing things to reduce the size and improve the response time of individual requests. Pagination is only one of the scenarios. There are situations such as during application start up where routine requests can take longer than you think they should.

RE: [flexcoders] Detecting Browser Re-Size
Nick, Steve,
Thanks for your input. To provide a little background data - I'm using the
DrumbeatInsight HTML component, which works pretty well so long as you're
left-aligned. But when the Flex content is center aligned, the IFrame overlay
does not compensate. So I was thinking along the lines of what Steve was
saying - listen to window resize and use external interface to have Flex
re-position the html content. I was really hoping for a solution that was less
of a hack and I'm hoping that it works well with multiple IFrames open at once
(which is my use-case).

Can you expand a little on the page layout you ha.vehttp://ha.ve that needs

browser resizes, the browser handles the moving using relative positioning.
So maybe forget that you've got an IFRAME and SWF, this fluid layout concept
will apply to any HTML objects such as two images.

RE: [flexcoders] Re: Uploading An Image Without Browse
James,
Using RemoteObject I've uploaded bitmap snapshots without previously saving the
bytes to disk, using CF as a backend. Not exactly sure how you'd do this with
PHP, but I'm sure it's doable. You'd probably have to use some version of
AMFPHP.

Subject: [flexcoders] Re: Uploading An Image Without Browse
Cheers Jeff. I'm sure that'd work too. I've found a way around it and can now
allow users to upload without the browse. The problem is though I now want it
to upload the file without it having to save it on the user's machine first. At
the moment my code snapshots the html component, saves this as a bitmapdata,
resizes this bitmapdata, then a jpegencoder turns this bitmapdata into a jpg
file which is named after whatever the user has entered into a text input
component in my app. It then uploads this jpeg from the location it's saved to.
I'm wondering is there any way of me editing my code so it uploads the jpeg
straight away rather than storing it on the machine too? Here's my script code
containing the function which does all this:-
mx:Script
![CDATA[
import mx.graphics.codec.JPEGEncoder;
import mx.graphics.ImageSnapshot;
private var imageuploadurlRequest:URLRequest;
private var serverSideScript:String = *my upload php file goes
here*;
private function imageuploadinit():void {
imageuploadurlRequest = new
URLRequest(serverSideScript);
}
private function takeSnapshot(event:Event) :void{
var bigbmd:BitmapData =
ImageSnapshot.captureBitmapData(linkviewer) ;
var scale:Number = 0.50;
var matrix:Matrix = new Matrix();
matrix.scale(scale, scale);
var smallbmd:BitmapData = new BitmapData(bigbmd.width *
scale, bigbmd.height * scale, true, 0x00);
smallbmd.draw(bigbmd, matrix, null, null, null, true);
var jpgEncoder:JPEGEncoder = new JPEGEncoder( 100 );
var ba:ByteArray = jpgEncoder.encode(smallbmd);
var enteredimagename:String = titleentry.text;
var file:File =
File.applicationDirectory.resolvePath(('assets/createdimages/')+enteredimagename+('.jpg'));
var wr:File = new File(file.nativePath);
var stream:FileStream = new FileStream();
stream.open( wr, FileMode.WRITE);
stream.writeBytes ( ba, 0, ba.length );
stream.close();

Steve isn't seeing the future so much as trying to create a future that provides best competitive advantage to Apple. And of course, as Adobe is fond of saying, Flash will push the envelope as to what is possible.

Adobe could, I'm sure, alter their Flash development tools to output SVG+Javascript. In fact, I'd be surprised if they hadn't already experimented with this. If Adobe was as smart as they think they are, they'd RIGHT NOW fast-track SVG+Javascript export into Flex and Flash IDEs. This would let them become the premier tool for developing iPhone apps, standards-based web vector animations and would encourage adoption of open standards at such a rate that it'd hobble Silverlight into the bargain! Flash is here because standards sucks. When standards will be good enough, flash will disappear, bunt won't happen anytime soon. Of course that is just an idle dream, and instead they will keep pushing their proprietary solution and wait for the killer open-standards IDE that will allow developers to make full use of HTML 5 to pop up and change the market for them.

Well put, Gregor. It does in fact seem that Apple is treated as more important than it really is, in terms of market share. Give that to their marketing and the support of fanatical fan boys and tech pundits. Just heard an ad last night for a Netbook touting that it's Flash Enabled - its possible that Apple's strategy of exclusion might backfire.

I'm assuming this is basically your desired tree structure:
-group1

--item
--item
-group3
--item
--item
Your probably going to need to put your data into a collection that looks
like this:
var myCollection:ArrayCollection = new ArrayCollection([
{group:group1, items:[item,item,item]},
{group:group2, items:[item,item,item]},
{group:group3, items:[item,item,item]}
]);
Then, you can use a dataDescriptor to tell the tree what properties of the
item object you want to display. The tree is packaged with a default
dataDescriptor, so your data either has to conform to its conventions to
display properly or you have to override it.
Implementing a very basic ITreeDataDescriptor and putting your debugger on
it will give you valuable insight as to how the Tree component traverses a
given data provider. You can then tell the tree how to display the objects
in your collection. Hope that helps.

RE: [flexcoders] Re: Framework Choice
Some architectural pattern is going to be necessary if the app is of any size and has a team working on it. Otherwise, each developer will solve their problems in their own way and can lead to chaos. You can formulate the architectural pattern yourself or use a published framework. As you said, using a published framework in some ways might make it easier to bring developers on board. Frameworks are intended to be implementations of architectural patterns - the framework choice IMO is based upon what gives you the best balance of freedom to solve your problems as you choose, with ways of solving problems without having to reinvent the wheel all the time. I've used Cairngorm a lot in the past, but I've kind of soured on it - doesn't solve enough problems, IMO. It is NOT module-friendly; in particular the ModelLocator singleton does not lend itself to unloading modules. I'm liking the direction that Cairngorm 3 is taking - it is less a proscriptive framework than a collection of best practices and libraries you can choose to use or not.

RE: [flexcoders] Re: Framework Choice
Even if you organize your code to some sort of internally formulated organization, you're already kind of using a framework - of your own creation. The disadvantage to that IMO, as soon as you start writing one you now become responsible for documenting your particular approach and communicating it to developers who might also work on your project. If your project needs to scale, using a published framework gives you the ability to find resources who also know the framework, and gets them up to speed more quickly. I've been on projects (otherwise known as nightmares) where the previous developer used no framework, and didn't document what they did.

Keep in mind, the people I'll be working with are relatively new to flex and the application is going to end up being quite large. Down the road it will likely have an AIR counterpart. We might use modules but for now I'm staying away from that because it adds another layer of complexity that in the initial stages is not needed. My thoughts on this are that Cairngorm would be easier to learn for them and they had talked about brining more people on in the future for this project. If that's the case, it would likely be easier to find people familiar with Cairngorm than some of the alternatives. But, I don't want to rule out any of the alternatives if they might actually be a better choice. Opinions please. Thanks! -Jake Churchill
RE: [flexcoders] Re: Flex 4....Large recordset...how much is too much?
Sounds like you need to decouple the scrollbar from the list control so that you can set the scroll bar min/max values based upon the size of the dataset, which would have to be returned as metadata, independently of the entire dataset. You move the scrollbar, an rpc call is made, and a section of the dataset is returned and rendered. This would eliminate the memory hit from bringing over a huge dataset of AS objects in one shot. The latency over the wire shouldn't be too bad, because at any given time you're only requesting a small portion of the total records. No point in returning more records that the user can practically interact with at any one time. See the VScrollBar control.

RE: [flexcoders] Binding Model Objects
Gregor, I'm doing a good bit of what you describe already - like chunking the number of objects transferred, only transferring what is needed, etc. My big question based on Sean's preso was making domain objects bindable. Right now, I am, for the most part. For example, when editing a specific record in a datagrid, it makes it so much easier to have that object bindable so I can load it into a form and have the UI reflect that object instance. To NOT make domain model objects bindable would mean creating a third layer for binding and loading a non-bindable model object into it. That is a total headache, but I'd do it, if it really made that much difference. I'm a little skeptical that a bindable AMF model object is going to fire off a bunch of events when received by the Flex client.

You can have entirely different structures for your DTOs, map multiple DOs to DTOs, keep your transport and domain layers separate (also allowing you to use different transport mechanisms AMF or XML over HTTP both easily swapped), and allow you a great deal of flexibility in structuring your application. Downside, yes the conversion process can be expensive, BUT only if you are planning on throwing around massive objects all the time. Taylor your service layer to be more responsive to your needs. Don't write a service which requires the whole object when all you need to send is an id (example, it's the difference between sending a whole email back to the server with the 'read' status marked as true, and just calling a 'markAsRead' service with the id of the email). Use paging techniques to break up your dataset, do you really need to fetch all 10k items now? If you are only showing them in 10 item chunks (i.e. in a datagrid) why not fetch them in 10 item chunks (or a few more for visual performance reasons). Well thought out business services can both reduce the amount of traffic you need to send, and allow DTO mapping to be realistic (on both ends of the wire). Gk.

Thanks Gregor,
I think I'm starting to get it. - by having client-side bindable objects,
using custom events, that are generated from DTOs, you minimize the amount of
generic change events being fired.
What about ObjectProxy? Can't similar results be obtained there?

Subject: RE: [flexcoders] Binding Model Objects
Jeff,
Yeah, I just jumped all over the DTO part of the discussion. Our DOs never get
near AMF.
We convert everything btw... each record in the DG ends up as an instance of a
DO (which is why the performance of the service layer is so important).
With DOs, we do make them bindable, but we use custom events to fire the
bindings, and we never ever make the entire object bindable, only the fields
required for the UI. The cheat here is when assembling the DO from a DTO, use a
method that doesn't go through the setters, and then dispatch the change event
once done, that way the binding operations can be done in a single frame rather
than being spread out.
Example (not the best architecture though).
public class fooDO extends EventDispatcher {
private var _bar : String;
public function set bar( b : String ) : void {
if ( _bar != b ) {
_bar = b;
dispatchEvent( fooChanged );
}
}
[Bindable(fooChanged)]
public function get bar() : String {
return _bar;
}
public function assemble( dto : FooDTO ) : void {
_bar = dto.bar;
dispatchEvent( fooChanged );
}
}
Quickly written out, but if all the bindable properties are fired off
fooChanged then the non-bindable DTO can be assembled into a Bindable DO and
cut down on the number of change events being fired. If the default
changeEvent is used, events will fire on each setter used which is where the
presentation is going.
Is that explained badly? Non-bindable DTOs assemble to bindable DOs in a way
that minimizes the amount of event slinging going on...

Gregor, Now that I look at it, I see what you're getting at - dynamic classes by nature are going to tax the JIT more.

[flexcoders] Binding Model Objects
I happened across the slides from a presentation that Sean Chirstmann did at
Max 2008 about memory optimization in AIR
(http://www.craftymind.com/wp-content/uploads/2008/11/sean_christmann_optimizing_air_final.pdf).
One of his points was NOT to make DTOs or AMF objects bindable. I've been
making my AMF model objects bindable for a long time and I just wanted to get
second opinions from the list.
I can see the point - if model objects are bindable and are bound using strong
references to display object properties using {}, it could result in object
instances persisting when they should be available to the GC. If true, I have
to do significant re-factoring.
I'm looking for corroboration here - anyone care to share their thoughts on
this?

Subject: [flexcoders] ADOBE AIR Qs: How do you load modules from app-storage
domain?
Hi all,
I am using AIR 1.5 SDK.
I am trying to find a way to build patching mechanism for my AIR app, which
consists modules, sqlite DBs, and other files, by updating ONLY files that need
to be updated.
I know that this is not possible using AIR Update Framework because the way I
understand it works is that any update that you have both minor and major, you
will have to reinstall everything. This is a pain if you have a huge size AIR
app.
I have sort of an idea to build my own update mechanism but in order for this
to work, I will need to be able to do update operation on my AIR app files.
Since app domain doesn't allow us to do that, I have to find a place where
updates can take place and my app could still work. I read that app-storage
allows you to do all of that.
Okay... so I build a really simple AIR app that the sole purpose is to load swf
module from app-storage to prove my theory.
So here's my AIR app code the short version:
mx:WindowedApplication
mx:Script
private function loadSwf():void
{
var dir:File = File.applicationStorageDirectory
dir = dir.resolvePath(SimpleSwf.swf);//SimpleSwf is the module
var myURLRequest:URLRequest = new URLRequest(dir.url);
var myURLLoader:URLLoader = new URLLoader();
myURLLoader.dataFormat = URLLoaderDataFormat.BINARY;
myURLLoader.load(myURLRequest);
myURLLoader.addEventListener(Event.COMPLETE,loadModuleCompleteHandler);
}
private function loadModuleCompleteHandler(pEvent:Event):void
{
var context:LoaderContext = new LoaderContext();
context.allowLoadBytesCodeExecution = true;
context.applicationDomain = ApplicationDomain.currentDomain;
var moduleLoader:Loader = new Loader();
var loader:URLLoader = URLLoader(pEvent.target);
moduleLoader.loadBytes(loader.data,context);
container.addChild(moduleLoader);
}
/mx:Script
mx:VBox width=100% height=100%
mx:Button label=Load SWF click=loadSwf()/
mx:UIComponent id=container/
/mx:VBox
/mx:WindowedApplication
The result is:
When I click the button Load SWF, I could see that the loader loads the SWF
correctly (it got the right size, etc) but I didn't see the module shows up on
the screen at all.
I didn't know what I do wrong.
Please enlighten me.

It 'worked' but realize that your MXML will not be recovered, only the AS code that exists behind it. Frankly, from the perspective of re-doing a project, the AS source code wasn't that useful to me. I ended up re-coding it from scratch. So, I'm not sure what you're trying to protect exactly but de-compilation isn't going deliver your Flex project to anyone, ready to be re-compiled.

[flexcoders] Chart Annotation Headaces
I'm attempting to add annotation items to a LineChart via CartesianDataCanvas,addDataChild(); There are two steps involved - one where the chart data is returned, immediately followed by my attempt at annotation. The results are inconsistent. Sometimes the annotation items (graphics) render properly, and sometimes some are dropped. I've been trying to find the correct event to listen to, thinking that perhaps the chart has to finish rendering with it's new ArrayCollection, but so far it's a mystery. updateComplete does not work as it creates an infinite loop as new updateComplete events are fired when new annotation items are added.

RE: [flexcoders] Re: better option than repeater?
This would be my approach:
You need two dataProviders (ArrayCollections), one being for the available
modules and the other for your list of staff. You'd only need two remote
objects to retrieve them.
Your modules dataprovider would be passed into each component instance and used
by the component to generate your list of available modules with checkboxes.
Your repeater is going to accept the staff list dataProvider. As it loops over
the ArrayCollection, it will pass the selected modules for a given staff member
to your checkbox component. It's up to you to write the setter function to pass
the selected values into your checkbox component and to set the 'selected'
property of each checkbox accordingly.

I don't quite get what you are trying to do.
Create a component. This component will display each staff member. Create a
public variable to hold each staff record (Value Object) and pass that record
to the component inside the repeater. The example I posted shows how to do this.
So, there is only one call to the RemoteObject service that returns an array
collection of staff objects. The data provider of the repeater is set to this
array collection. As the repeater runs, each instance of the component gets one
staff record. You use this record to figure out which checkbox is to be set.
An mx:RemoteObject can be used wherever you need it. I have components with
Remote Objects that are repeated. The first remote object call gets the data
for each component which then makes its own RO call to get further data if the
user selects that component. As an example, in your situation, you could have
each staff member displayed with a button labeled More Info. If a user clicks
this button the RO in this component will make a call to the server to get more
info for this staff member.

I need to loop through all the modules and output a checkbox...and if
the module's SEQ is in the Staff's moduleAccess list then the box should
be checked.
I tried setting up a remoteObject inside the custom renderer, but no
matter where I put it it gave me a parse error. I guess it doesn't like
mx:RemoteObject inside a component. So I put it outside the component,
but then the script function inside the component didn't seem able to
access the RemoteObject's data. Although it was what I initially tried
to do (with the RO inside the component) I don't really want to do that
as it seems highly inefficient to query the database for every Staff
record. It seems I should be able to execute the RO just once and then
pass the resulting list of modules to the component so I can loop
through it to output all the checkboxes (and for each record check the
SEQ against the Staff's moduleAccess, which I know how to do).
So the question is - how do call the RO just once and pass the result
into the component (as an ArrayCollection or something) so I can loop
over it repeatedly instead of actually calling it and hitting the
database repeatedly?

RE: [flexcoders] Unloading Modules - Binding is the Enemy?
Alex,
About weak reference listeners - what kind of listeners are created when
bindings are defined in MXML? Like dataProvider={myAc}? And would it
help to use [Bindable] myColl:ICollectionView as the source? I hear you
on trying to make things like this easy. I think the ViewStack loading
Modules conditionally is a pretty common scenario for app development.
One of the things I am seeing is that it easier to get the module to
unload if it isn't the currently selectedChild of the ViewStack, but so
far I get the best results when a brand new module is loaded before
exiting the application. Then the other module becomes relatively easy
to gc.
In my app, one of the modules manages a particular product type. Based
upon search criteria, a datagrid will be populated. If they want to
edit a given dg item, there's a popup editor which makes a copy of the
editable object and binds that to a form. The user makes edits and
chooses to save or not the item. Right now, that's what I'm focusing
on, because the editable copy I make seems to be hanging around in
memory after attempting to unload the module and might be contributing
to the problem.

Enemy?
I haven't looked at ModelLocator, but in general, if you have a
single instance of something and are binding to it from a module, code
in the module will add a listener to the single instance. This creates
a reference from the single instance to the module, but Binding should
be using a weak reference listener. Maybe it is time for me to build a
test case and look. We want to make this kind of thing easy. If
ModelLocator keeps its own list of subscribers, that could be a problem.
If your local models are listening for changes to the central model and
not using weak reference listeners that will also be a problem.
If the PopUp is being gc'd then that should no longer pin the
module. I haven't looked at many popup scenarios so there could be
something there. In general though, I've found the profiler will
eventually tell me the answer. I assume you know that new classes pin
modules if they bring in new Style definitions that get registerd with
the StyleManager.
That said, the Flash Player will not always gc() everything it
could in one pass, and sometimes does hang onto things a bit longer, so
the load/interact/unload/checkmemory test will not always succeed. If
loading the module again or loading a different module eventually causes
the release of the first module, we consider that success. Another
test we run is an overnight test of loading and unloading modules that
are published for release mode (no debug info) and run on the release
player instead of the debugger player. Memory should stabilize after a
while. The debugger player has a reputation for hanging on to things
that the release player won't because it is handling debug info in the
debug SWFs.

Thanks Alex, very much. The main app is only handling
login/logout duties and the event-command-delegate classes to do so. I
moved away from ModelLocator in the concern that it, being a singleton,
may be keeping a reference to UI objects that are using ModelLocator
objects as dataProviders and thus prevent a clean unload. After all, by
definition, a singleton is going to persist after a module is unloaded,
true? Maybe I was wrong about that, but I'll tell you, I was trying
everything to get that module to unload. Everyone was a suspect. Bear
with me while I try to get my wits around this stuff. What I'm doing
how is keeping all my models local to the module that uses them and
injecting data via command and delegate classes. This seems to work ok.
As far as PopUps, I'm calling removePopUp() and also removing
listeners to custom events I've defined in the popup.
I'm also seeing some behavior where the module will remain in
memory after unloading (as reported by the profiler) until I create a
new instance of that particular module class and populate the
dataProvider of one of its children. The holy grail of a 100% clean
module load/unload has not been attained, but I believe I'm

Alex, I was using 3.2 - an oversight on my part - I upgraded to 3.3 and it does seem to help but I'm also calling focusManager.deactivate() as well. Since that, the combobox isn't an issue. However there any number of different things I was doing that were causing problems - like binding myModule.currentState to a model. One of the challenges is injecting model data into the module that doesn't create a refererence to the module anywhere. PopUpManager seems to be problematic if the popup contains strong refereneces to the module or its associated model. I am making progress and what I'm hoping for in the end is a definitive set of best practices concerning the use of modules.

RE: [flexcoders] Unloading Modules - Binding is the Enemy?
Thanks Alex, very much. The main app is only handling login/logout duties and the event-command-delegate classes to do so. I moved away from ModelLocator in the concern that it, being a singleton, may be keeping a reference to UI objects that are using ModelLocator objects as dataProviders and thus prevent a clean unload. After all, by definition, a singleton is going to persist after a module is unloaded, true? Maybe I was wrong about that, but I'll tell you, I was trying everything to get that module to unload. Everyone was a suspect. Bear with me while I try to get my wits around this stuff. What I'm doing how is keeping all my models local to the module that uses them and injecting data via command and delegate classes. This seems to work ok. As far as PopUps, I'm calling removePopUp() and also removing listeners to custom events I've defined in the popup. I'm also seeing some behavior where the module will remain in memory after unloading (as reported by the profiler) until I create a new instance of that particular module class and populate the dataProvider of one of its children. The holy grail of a 100% clean module load/unload has not been attained, but I believe I'm getting closer.

Every time I've debugged a suspected Binding leak, I've found that it sets up weak references in the right places and the problem was always somewhere else. However, I wouldn't bet against there being a scenario out there that does leak. We're looking at other module unloading scenarios right now so I'd still be willing to look at a simple test case. IMHO, the main app should never reference the model. If you have a model Singleton, the module can bind to the singleton. IMHO, that's a better model/view design anyway. I would expect all popups related to the module to be removed in order for the module to unload. One aspect of the modules design is that it does not require an unload() command. The design was that you would load a module and generate an instance (or several) of the module's classes and once you've cleaned up all references to those instances, the module would go away in a future gc pass. That way, you wouldn't have to track instances and know when it is time to call unload(). In order to implement such a design, the module SWF is given an unload() call right away so that its generated instances are supposedly the only remaining references to the modules classes thus preventing garbage-collection. Given the current design, I don't think we can ever substitute unloadAndStop() for that unload call. Also, no testing has been done by the Flex team as to what impact unloadAndStop will have in ActionScript if references to objects suddenly become invalid. IMHO, unloadAndStop should only be used when there are well-defined boundaries such as around a sub-application since sub-apps tend to be more self-sufficient. Modules are much more tightly integrated with the main application. However, Modules or no Modules, we realize that debugging memory leaks is hard work. The Gumbo profiler has a new backreference display that eliminates most extraneous backreferences, and we welcome any other ideas for tools and techniques for finding leaks.

Alex, I was using 3.2 - an oversight on my part - I upgraded to 3.3 and it does seem to help but I'm also calling focusManager.deactivate() as well. Since that, the combobox isn't an issue. However there any number of different things I was doing that were causing problems - like binding myModule.currentState to a model. One of the challenges is injecting model data into the module that doesn't create a refererence to the module anywhere. PopUpManager seems to be problematic if the popup contains strong refereneces to the module or its associated model. I am making progress and what I'm hoping for in the end is a definitive set of best practices concerning the use of modules. Hopefully some of these issues might be made easier with somehting like loader.unloadAndStop() but for modules. Jeff -Original Message

[flexcoders] Unloading Modules - Binding is the Enemy?
In testing via the Profiler, binding UI objects in a module to a model (even if local to the module) appears to be causing a module's failure to unload. This happens as soon as the UI component becomes active. In fact, even if the source object (data provider) is set to null, the binding persists and will prevent a module from unloading. Does this issue have to be such a PITA? It appears that using curly braces for binding in MXML can create Modules that won't unload. In FP 10, the Loader class has the new unloadAndStop() method. Would be extremely handy to have something similar for Modules. Basically you want to remove all listeners to a model and then unload the module. Seeking enlightenment - anyone got any?

RE: [flexcoders] Unloading Modules - Binding is the Enemy?
Pedro, I've been running the GC immediately after unload - programmatically. The module instance is released immediately if binding is inactive. The moment binding becomes active to a UI element of the Module, the instance will not be released. I was thinking that having the model object I'm binding to be local to the module would address the behavior, but sadly it does not appear to work.

Hi Jeff, The fact that you unload a module does not mean that it will be garbage collected(the memory won't be released as soon as you unload your module).

You may call it, but it won't be executed if it is not necessary. Clicking the Run Garbage Collector button does not guarantee that all objects that are eligible for garbage collection will be garbage collected.
