Re: [flexcoders] Any Stable Enough Flex 4 Nightly build around?
Hi Peter, This particular error is still present in build 10608, although other things run quite smoothly. I haven't been able to isolate the error just and create a testbed yet (probably will soon), but for now what I can tell you is that it appears when I add, via Actionscript, a new halo Form to a spark Group container. This container is being heavily resized and animated up until the form is added to it. The end result is that the whole application looks messy but no RTEs are thrown, as if the Layout process went crazy from this point on. I am using intermixed Halo/Spark components in other parts of the app and this seems to be the only issue of the kind.

[flexcoders] SWC Cache messing up Flash Builder 4; Implicit coercion of a value....
Hi, I know this bug has been around for a while and results in type errors such as: 1067: Implicit coercion of a value of type mx.rpc:Responder to an unrelated type mx.rpc:IResponder. I can live with that. But now I am finding that I cannot export an AIR project at all. I use a dozen libraries ( linked projects ) so this is probably creating more space for the error to show up. I need a workaround. Is there a way to tell the compiler to skip the swc cache? Or maybe just avoid type checking? ( the latter sounds a bit too extreme and probably unreal ).

Re: [flexcoders] Re: BlazeDS RemoteObject Performance
Hi, Yes! We figured yesterday that it is, in fact, a *client side* limitation. We are using AIR 1.5 BTW. Is there any workaround for this? We are changing the overall strategy to consolidate several queries at once, but it would be nice to raise the client side pool a bit more ( having only two is sub-optimal anyway ).

[flexcoders] BlazeDS RemoteObject Performance
( I copy this email from an internal communication I received ) quote Hello, I've found a serious performance problem on an application written on Flex/AIR and using BlazeDS v3.0.0.544. By looking at the logs I can see that the server side method (invoked via RemoteObject on the client side) never executes in more than two threads at the same time. What I mean is that if I fire 5 simultaneous requests to the method using RemoteObject from the flex side, and log when the method is executed and when it returns, I get something like this: 12:00:00 Method Executed 12:00:00 Method Executed 12:00:01 Method Exiting 12:00:01 Method Executed 12:00:04 Method Exiting 12:00:04 Method Executed 12:00:10 Method Exiting 12:00:10 Method Executed 12:00:11 Method Exiting 12:00:13 Method Exiting While on the client side I see that all the 5 invocations were fired at 12:00:00. As you can see, the method tend to take a while to run. But the big problem is that the log suggest that some queuing is happening on the server side, allowing only a maximum of two threads to run in parallel at any given time. I thought it could be a problem with the thread pool of the servlet container, but my Tomcat has the following configuration: Executor name=tomcatThreadPool namePrefix=catalina-exec- maxThreads=150 minSpareThreads=4/ So I guessed that the limit could be imposed by BlazeDS itself. But haven't found anything on the documentation. Of course, I could be wrong and the problem may be something else. Any ideas?

[flexcoders] Populating NativeMenu with async call; AIR
Hi all, Is there any way to incrementally populate a NativeMenu after it has been displayed? I need to show the menu upon right-click, send some queries back to the server and, depending on the replies, show custom actions. It looks like this is not possible, but I'd rather ask as it might be a common use case. One alternative is to use Windows instead of NativeMenus. But that means looser integration. Thanks!

The question I have and would like to answer before wasting more time is: Do you think that I can achieve a similar performance with the Flex Charting framework?

In that case, I guess I would be better off creating some simpler bubble chart implementation using pv3d for rendering ( for example ), or just use a different platform for this experiment.

Re: [flexcoders] Achieving weak-ref VALUE Dictionaries; Alternatives
Hi Tom, Because I would only like to delete those that are not in use... just like Garbage Collection. If I just removed every reference I could not achieve identity allocation ( which is a requirement ). To clarify: Suppose you are coding an email user interface, like GMail, where there are potentially thousands of distincts messages. You are modeling messages using a value object ( EmailVO ) that holds substantial data ( subject, sender, text, etc ). Now, for some reason, you MUST make sure that there is one EmailVO instance exists per-email at a given moment in time ( I repeat, this is an important requirement in my case ). See... I need a factory with a cache that knows how to return the singleton copy of each EmailVO ( based on a hash of the email ID or something like that ) BUT that is smart enough to allow for GC. While some of these emails will surface constantly at the user interface ( while reading a thread ) others will only be used for mere seconds and will never appear again. It makes sense to remove the latter from memory... specially when we are approaching six figures in magnitude.

Re: [flexcoders] Achieving weak-ref VALUE Dictionaries; Alternatives
Yes, get your point... but that won´t solve it either. ( Sorry, I am having trouble expressing myself. ( I am still up after an all nighter ) ) Use a Timer to flush objects with timestamps more then $TIME ago. Ok, suppose I flush the objects in the cache ( within the factory ). And then an email with id 3 comes along, for which I create a new instance. Now, in some other part of the framework, the old instance of the email with id 3 ( before the flush ) is still laying around, and sooner rather than later I find myself comparing them using strict equality. The operation yields false even though they are semantically equivalent. This is the whole point. I CANNOT use value based comparison ( eg. implement a compareTo() or o1.id == o2.id ), only native IDENTITY comparison. This limitation is by design. I am doing some complex relational algebra in memory. Actually, its not event identity comparison, but small integers associated to these instances that are ultimately stored and in bitmap indexes and operated on using bitwise ops. So, what I am looking for is some insight about the different approaches of constructing weak VALUE reference ( in contrast to KEY reference ) dictionaries. I need some sleep apparently.

[flexcoders] Achieving weak-ref VALUE Dictionaries; Alternatives
Hi all, I have a situation where I need to pool a certain type of objects based on their value, so that for each for each person ID I have at most one PersonVO living at a certain moment This way I can always test equality as follows: personVO1 === personVO2 instead of a custom value based method: personVO1.equals( personVO2 ) The most obvious way of achieving this is to use Factory backed by a dictionary or hashmap using personID as key. The problem is that, after some time, I can potentially deal with tens of thousands of cummulative distinct persons, but each one is used only for a couple of minutes and won't occur again. Having each instance referenced by a hashmap will only result in an inevitable memory leak. So, basically, what I need is a dictionary with weak *references* instead of keys... I thought about using one dictionary in the middle and store the PersonVO instance as key ( pseudocode ) to store var tempDictionary:Dictionary = new Dictionary( true ); tempDictionary[ personVO ] = true; personIDToPersonVOMap[ personID ] = tempDictionary; to retrieve for ( var personVO:PersonVO in personIDToPersonVOMap[ personID ] ) return personVO; // if for loop does't hit any key then the value object was garbage collected, and I can create a new one This should, in theory, work... at the expense of some obvious overhead ( one new Dictionary instance per value object ). A second approach I was thinking about is not so straightforward but might perform better: - Use a normal hashmap to store the value objects - Every now and then, create a dictionary with weak keys and put all the value objects as KEYS - delete the hashmap - wait for GC to run - after some time, or on demand, iterate over the keys ( that were not GCCollected ) and repopulate the hashmap Of course the latter approach will only work if the GC runs during the no-hashmap interval. Is there any way to fire the GC manually? ( creating a zillion empty objects perhaps ) Any ideas? Thanks, Aldo -- Aldo Bucchi +1 858 539 6986 +56 9 8429 8300 +56 9 7623 8653 skype:aldo.bucchi
Re: [flexcoders] Re: On mx.collections and the missing data structures... Set, Map, Queue, etc
Thx
Who implemented mx.olap?
He sure learned something about sets, bags n stuff.
Any tips? Performance / memory considerations?
I am pushing flash.utils.Dictionary to see how far I can get. Looks
solid enough to implement identity based sets and multisets.
Best,

[flexcoders] Emulating Flash MultiThreading; Approaches
Hi Guys, I need to run an expensive computation in the background ( 2 seconds on a modern day laptop ) while keeping the UI responsive. For this matter I have tried creating a secondary application and communicate with it in a non-blocking way. I share my thoughts so far to see if anyone can help with this one. First, some approaches to create a secondary application: * Load a module at runtime * Publish a module from within a new Frame ( Gonzalez/Harui trick ) * Open another SWF altogether ( seems the safest best bet to me ) Some approaches to communicate between apps: * LocalConnection ( sync ) * Write/Poll a LSO ( async ) And to go from blocking to non-blocking communication ( maybe ) * Upon receiving a call start a timer and listen for the completion event. This should make the call return while leaving it up to events to start the real processing. Now, I haven't tried every combination yet, but so far I found some interesting results: I created two separate applications that talk through a LocalConnection. They use the timer trick ( upon receiving a call they set up a very short internal timer that will eventually start internal execution of the code ). If I open both SWFs in IE they effectively work as expected. I can start a very heavy computation on the secondary app while the first remains totally responsive to user events. Then I can make a reverse call and pass the results back. So far so good :) Firefox, however, is a show killer. No matter how I open the two apps ( tabs, apps, etc ) blocking occurs. Can someone from the flash player shed some light on this? This is not real multi-threading, it is simpler in the sense that I don't need synchronization. The contract is passing an input and waiting for a result. Now, even if I managed to pull this off with parallel applications... how would I materialize that setup in AIR?

Re: [flexcoders] Re: Emulating Flash MultiThreading; Approaches
Seth, Josh,
The reason I have not used timers is because I can´t. The algorithms I
am executing are not decomposable into discrete steps without titanic
efforts. Evaluation of bitmap indexes in memory for intense relational
algebra stuff.
I do have a class that encapsulates a pseudo-thread and allows me to
process chunks... it goes a long way to support a hierarchical stack
for recursion, facilities to manage context between calls, timers, and
a even a way to plug into the suspend background processing stuff in
the framework so it yields nicely to effects.
But, it won´t do the trick this time.
So, back to the multithreading... Is it totally impossible?
Thanks,
Aldo

I'd have to agree with Seth, though I would suggest using a timer, as

In the past I've actually written a light weight class that

[flexcoders] Aha... did someone say C/C++ to AS3???
woo I just saw the video [1] damn. list... how come I see so little buzz on this!!!?? It is THE biggest thing I have seen so far related to the flash player. Bu, bu, please!!! - is this real? - when should we expect this to hit the street, if ever ( we need to get prepared ya know... ) - hmm what happens with licenses... can we just port EVERY open source c/cpp interpreter, codec, lib, etc to as3? damn. this is one of those things that make me question everything about everything. It just changes the rules of the game completely. It is too good to be true, and at the same time too bad... i'm confused. Of course, it makes sense. In the race for the WebOS desktop... Adobe will have to port their desktop applications to their universal client platform. How much will the photoshop v.2010 online subscription cost? anyone?

Re: [flexcoders] Aha... did someone say C/C++ to AS3???
Jon, Well, I am leaving the cool factor away, but it is still cool. Honestly, I don't really care about porting quake or any other super pop tech... neither sound nor graphics rendering software. Porting the ranking system of a bw version of pacman is already scary enough! As you point out, having access to a tool ( or even just a cheap methodology ) for porting c/cpp code opens a new world of possibilities, and drastically changes the rules of the game. Basically, it is now business to create a library and become the first to have it in AS3... probably not an evident niche to the rest of us because AIR has not hit the streets yet, but I can bet more than one company is doing something in those lines. Take the very same Adobe and their Flex IDE as a cannonical example... how long would it be, after the release of such piece of machinery, before someone ports a compiler generator et al and gives something like FLEXible a final push to completion. Or someone creates a solid migration tool from another UI technology with established IDEs to Flash? Of course you might argue that the flex framework is unparalleled with binding, repeaters, events, effects, etc. ... but isn't it opensource already? and with respect to other technologies, now that the ideas are on the table, it's just a matter of playing catch up... which will be quite fast given that, as Scott Peterson emphasizes, we can even port interpreters for other languages. And what about LCS?? It might not have a contender right off the shelf but, hey, having the ability to port libraries puts me much much closer. And closer to building something better! Or even something that runs with MS technology in the backend. Of course this would definitely lean the balance against silverlight and other contenders in terms of developer adoption, but at what cost. If part of the player is OS ( correct me is im wrong ), the framework is OS, and now we can port code and run it in Flash... what's left for Adobe to profit from? Perhaps acrobat...? or Media Server? ( oh.. red5 ). So, wrapping up, I think this announcement deserves a LOT more attention that what it's had. They somehow opened Pandora's box with that short demo. I just don't see a clear business strategy behind the move. I might be missing very important point but with my current understanding this scares me a bit... quite a bit to be honest. After all, some of us are betting on the sustainability of this platform. To a certain degree, Adobe might be shooting themselves in the foot with this one. I am very interested to hear some informed opinions.

Re: [flexcoders] Aha... did someone say C/C++ to AS3???
to AS processor doesn't change the situation. The real differentiator in our world is the Player, not the language. Of course you might argue that the flex framework is unparalleled with binding, repeaters, events, effects, etc. ... but isn't it opensource already? But it took thousand and thousands of man-hours and a significant amount of people to develop the framework and to support it. I challenge anyone to attempt to do the same. If there is a business case to be made for another tool that can match the capabilities of the Flex framework, then by all means. Have fun writing 200k of relatively bug-free code. :) And what about LCS?? It's supported, it's backed by the thought leaders on the technology. Sure, a team of very smart developers could put together a similar offering, but they sure couldn't support it the same and they would always be playing catch-up to those that are developing the technology in the first place. Adobe is the thought leader and the first adopter. If part of the player is OS ( correct me is im wrong ), the framework is OS, and now we can port code and run it in Flash... what's left for Adobe to profit from? Perhaps acrobat...? or Media Server? ( oh.. red5 ). The Player is not open source. It's a closed, licensed model. Another very important point is that, from my understanding, it's against all EULAs to write your own Player - write a public SWF runtime and they'll sue you. :) It's a closed market and it's highly unlikely to change soon. To a certain degree, Adobe might be shooting themselves in the foot with this one. I don't think they are really. Adobe is a huge company. They control the Player, which is a necessary evil now they've gotten this far with the technology. The Flex line of products is a very small portion of Adobe's revenue. The Flash IDE is way more ingrained in the market than a niche tool like Flex. Their real focus on this stuff is the entire enterprise process and workflow. Their analyst meeting documents are always a great read and give some pretty good insight into where they are positioned. Stuff like that Quake technology demo are to keep us happy, imho (and they did a dang good job!), but It's miniscule in the grand scheme of what Adobe does. In the end, it's a code converter. Anyone outside of Adobe could've done it - they just did it first. Glad they're still the thought leaders. cheers, jon -- Aldo Bucchi +1 858 539 6986 +56 9 8429 8300 +56 9 7623 8653 skype:aldo.bucchi -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

Hi all, I happen to have a colorpicker control located in the lower end of an application. When the dropdown is displayed part of it falls off stage. Not quite usable. I cannot find a way to tell the colorpicker to open towards other direction ( upwards for example ). Ideas anyone? Thanks, Aldo -- Aldo Bucchi +56 9 8429 8300 +1 858 539 6986
[flexcoders] Getting styleNames at runtime?? ( CSSStyleDeclaration::getExplicitStyleNames() )
Hi All,
I need to be able to duplicate style declarations at runtime... and I
hit a wall:
Is there any way to do the following??
for each ( var styleName:String in myStyleDec.getExplicitStyleNames() )
{
trace( styleName + = + myStyleDec.getStyle( styleName ) );
}
See, I'm really missing something in the lines of
CSSStyleDeclaration::getExplicitStyleNames():Array
I can see some private or protected members of the class that may hold
that info, but no public way to access it.
Any ideas?
Is this by design? ( I might be missing the bigger picture here...
after all this things are called cascading for some reason )
Thanks!!

[flexcoders] IDs within repeaters and Bindings
Hi Flexies,
Components within a repeater have IDs that are not document-scoped,
thus the following binding expression will only work once.
mx:Repeater
foo:Bar id=bar/
mx:Label text={bar.bindableProperty} /
/mx:Repeater
I need a way to overcome this... so that the expression is valid for
the lifetime of the application.
I have tried to do things like
mx:Label text={findBar(repeater.currentIndex).bindableProperty}/
where findBar somehow uses the repeater index to return a reference to
the desired instance of Bar.
Now, the latter doesn't work either... as the binding still only works once.
Any ideas??
I understand this is a current limitation, but are there any hacky
ways around it??
Perhaps using separate mx:Bindindg tags?
( hmm hadn't thought about that... will give it a try )
Thanks,
Aldo

Re: [flexcoders] Re: Brainstorming; Dynamic Conditionals in MXML
Hi Gordon,
I can see the point. It is indeed confusing at times... but still, I
have built a primitive implementation and it has made my life much
easier.
Think about this simple but common use case:
I have to generate form from an XML spec. As i iterate through the
form item nodes I have to instantiate the correct controls ( may be
datechoosers, textinputs, etc ).
I would really like to keep everything in MXML ( i am trying to use as
much binding, repeaters, etc as possible to keep things concise and
easier to mantain ) but I am missing the ability to conditionally
instantiate one control or another.
The following class allows me to do conditional instantiation using
MXML, and it has saved me TONS of code. It is still work in progress
but it makes the work for now. Here's a small tada list off the top of
my head
* extend repeater or sth like that so it adds children to the parent container
* allow for runtime changing of the selectedIndex
* figure out some binding issues and creation/destruction policies
any help and ideas.. more than welcome
public class Switch extends HBox
{
private var _selectedIndex:int;
public function get selectedIndex():int
{
return _selectedIndex;
}
/**
* if changed at runtime, for now we are doing nothing
* we can try sth later...
*
* @param value
*
*/
public function set selectedIndex( value:int ):void
{
trace( set selectedIndex + value );
_selectedIndex = value;
}
override public function
createComponentsFromDescriptors(
recurse:Boolean = true ):void
{
if ( childDescriptors.length == 0 )
return; // no children specified
// remove current children
if ( selectedIndex != -1 childDescriptors[
selectedIndex ] )
{
trace( createComponentFromDescriptor
+ selectedIndex );
createComponentFromDescriptor(
childDescriptors[ selectedIndex ]
, recurse );
}
validateNow();
}
}
conditionals:Switch
selectedIndex={getSwitchIndexForFormItemNode(rep2.currentItem)}

When we implemented mx:Repeater, we considered whether to add conditional
tags like mx:If. We decided against it on the grounds that it would be
confusing about whether these tags worked at compile time or at runtime. We
felt that dynamic runtime logic belongs in script, not in declarative
syntax.

just realized that you can accomplish something similar by using

i need to destroy children when the condition changes, to avoid
parameter problems... but still. that only leaves me with binding
issues.
OTOH, the ideal way would be to create a custom component that
implements IRepeater so that containers don't add it, and then play

[flexcoders] CSS Gurus: Different StyleManagers within one Application???
Hi all, I have two different applications ( swfs ) that are loaded at runtime using two SWFLoaders inside a third application ( that acts mainly as a shell ). I need their CSS styles, skinning, etc to be independent... but the behaviour I get is that their styles get merged ( first one loaded wins ). Is it possible to achieve this separation?? What I am doing is something similar to the Flex Style Explorer, but the controls used to tweak styles at runtime have to be stylable using an independent, inmutable CSS file... their styling MUST NOT be affected by any runtime modifications. I cannot create specific class selectors for these controls, because the CSS file already exists and makes use of type selectors as well. One obvious solution is to make two completely separate applications and have them talk through a LocalConnection. But this leads to some unwanted layout problems in my specific case ( ColorPickers on the controls application won't be able to hover over the other app, thus not leaving them enough real estate to display correctly ).

On 12/11/06, Lachlan Cotter [EMAIL PROTECTED] wrote: Hi Peter, Thanks for this information, it has certainly helped to clarify some things in my mind. With Cairngorm Enterprise one of goals is to promote an application model on the client (RIA) and a domain model on server. We see the application model being a good OO model that reflects the UI and tells us about the entities and their relationships that we are surfacing. It will also encapsulate all the business rules that apply to the UI. I see this being different to the domain model and the business rules that reside on the server. The thing that is most interesting to me here is the talk of relationships because this is what seems to be lacking somewhat in the current Cairngorm paradigm. Not to imply that it can't be done, just that it doesn't seem to be part of the standard practice. This sort of shifts the concept we have at the moment, whereby you call a command, which may invoke a service via a delegate. In essence we are going to move the delegates behind the model and have the command call an operation on the model. This sounds promising. Where does this put the service locator? In essence it would be nice to see VOs / DTOs being used for transporting data rather than making their way in to the view via the ModelLocator. Again, glad to hear this is an issue for others as well. In simple cases, the VO is adequate because it sufficiently represents both the domain object and the view you want to take of it. When the relationships become more complex however, inconsistencies begin to arise. For example, when you have many-to-many relationships and such and you want to be able to traverse the object graph in bindings or whatever, you need to construct a more interconnected object graph rather than a collection of records as it were. Then you have the problem of how you get from A to B. Is there a best practice you are advocating for mapping and building object graphs out of data in DTOs? or is it left up to the specific requirements of the application? -- : Aldo Bucchi : mobile (56) 8 429 8300

[flexcoders] Eclipse + Flex2Plugin + Subversion + Ant + Webserver Quickstart
Hi flexies, I have spent a long time in utter silence... work has pushed me to distant places these days. But I'm back... and... totally out of practice, hehe. It is in this comeback that I have noticed that, within my team and apparently the vast majority of the mailing list, there still isn't a one-stop-shop for flex development setup. Well, this is not strange given the short lifetime and fast paced evolution of the product. But still. I happen to be writing some standards for flex architecture and development workflow. So I have to come up with something, well, standardized. I totally agree with Dave Wolf @cynergy that a top-down, user-centered, small iteration approach is very effective and has two consequences: happy users and natural separation of concerns. I have built fully functional prototypes consuming a mock model in the client, and by the time I hand in requirements for the backend, I have a pretty clear idea of what I want ( or better yet, what I need... not like they really care about what I want ). Perhaps we could all brainstorm for a while and see if we can generate a simplistic taxonomy on the variety of projects and throw in a workflow cookbook for each? Some axis' for classifying flex projects: * number of developers * separation of concerns ( different teams for backend/client? mixed? ) * uses dataservices? * iterative releases? one monolythic release? * uses cairngorm? ( did you say no?... ) * any topology restrictions? ( rephrase, can you just test locally or do you need to deploy on a appserver, loadbalanced, megacomplex environment for some reason? ) Guidance should cover the following ( at least ): * Recommended requirement development workflow ( we could stick to use-cases as suggested by cairngorm to reduce variety here, and specify interactions between team members. Flex first, then java, etc. ) * Recommended team interaction workflow ( who leads?? flex or backend? when do we test? etc. ) * Recommended topologies, identifying advantages and drawbacks ( in small projects, a colocated test webserver in each dev station might suffice. Otherwise, a central testing environment might be needed. This affects workflow and file layout, as well as versioning setup ). * File layout plus Version control integration and recommended workflow ( not trivial! we now have flex + flex libraries + dependencies + java + etc. things can get messy ). * etc... I know this sounds like a hard task, but I am sure that using an 80/20 approach we can create a standard workflow that will help all newcomers ( specially those coming from the client-side of the game ) to get up and running with a particular ( again, 80/20 ) kind of project. So, eating my own dogfood, my 2 cents on the 80/20 project: * iterative releases ( not monolythic ) * 4-20 services(rpc or fds), 2-4 flexdevs, 1-2 backend devs * 10-50 screens * Cairngorm by the book. ( some creative deviations always arise, but use-case command guiding backbone and front controller as a central bloated organizer is kept. this is probably a necessary assumption to make this classification possible ) * Flex Builder, eclipse, subversion ( could be others, but subclipse and familiarity make this a comfortable choice for many ) * Tomcat/JRun/Jetty for local testing ( could be an app server as well, but these are usually lighter and thus swifter when run side by side with eclipse ) * FDS or just RPC ( both be run from within a webserver ) ( if you don't like the numbers, then read medium sized. just guessing but makes the point and allows debate, which is exactly the idea ) Ok, how would you recommend setting up dev stations for that project? workflow? where does flex meet the backend? when? where do we unit test the different environments? how do we package and when? etc... A byproduct of writing down some recommendations is that we would then have more leverage to convince or fellow non-ria developers that we are not making things up. RIA development IS different in nature, since we have ( like it or not ) a dazzled user in the center, facing a totally new experience. and sometimes a dazzled developer jeje. This is quite different from the traditional webpage+usecase to backlog we are all used to. Again, I fully support top-down mocks. It's like being able to simulate 3d full sized houses before building them. risk killer and keeps the user happy! BTW, remember that there are lots of fella developers coming from less tech-savvy backgrounds ( designers, webpage devs, etc ). Flex can be a little hard to swallow. How many of the newcomers to the list have run into Eclipse for the first time when setting up Flex Builder?? Best ;) Aldo -- : Aldo Bucchi : mobile (56) 8 429 8300

Re: [flexcoders] weakreference??
aha! thanks so we have weakreferences... but only for the *keys* of the dictionary... but i need them for the values so I can create ordered lists and maps list[0] = weaklyReferencedObject1; list[1] = weaklyReferencedObject2; list[2] = weaklyReferencedObject3; map[blabla] = weaklyReferencedObject4; map[bloblo] = weaklyReferencedObject5; of course I could iterate through the keys of a dictionary. that would spit out the order in which the keys were added, right? now, another way would be to use one dictionary per entry ( on another dictionary or on a simple object ). I would then know that the weakly referenced object I am interested in is THE ONLY KEY available... I could wrap this into a custom class using flash_proxy to make it more usable. hmm but what about performance. ideas?? is there any class in the framework that has weakreferences for the values instead of the keys? thx, Aldo On 9/15/06, Ralf Bokelberg [EMAIL PROTECTED] wrote: Isn't this, what the Dictionary's constructor parameter is for?

[flexcoders] Building a chat server over FDS... impossible is nothing??
Hi all, I have asked this before... it's just to see if things have changed in a while. It turns out that I have a frozen Flex 2 project that requieres a Chat server ( video chat actually ) and uses FDS a lot. I would really like to use FDS for the chat logic as well ( which is actually much more complicated than a simple chat... it has queues, presence states are used in business logic, etc ). But I am missing the chat-oriented design of a product like FMS2. Note that I DO have FMS but I would end up building a really complex system ( divided in two parts, which have to talk all the time... ). Alternatives: * FDS + FMS talking through web services ( the java bridge is not officially released ) ** horrible solution since the complexity of the system goes through the roof ** Even if the java bridge existed ( I would rather have the FMS model replicated in a java environment, much better ). * FDS with a custom made chat server on top of messaging. ** Nice, but I have to build this functionality and it is not trivial ( has anyone done this already? ) * Red5?? ** I need to travel in time... and to clear the FUD for my client. * Flex2.x?? ** time travel again... Any comments on this situation??

Re: [flexcoders] Building a chat server over FDS... impossible is nothing??
Hi Tom, I think FDS is a great solution for a lot of different problems, but it's just not the right tool for the job in our case. Yup, we definitely agree on that one. OTOH, I can't build this app exclusively on FMS since the connections, states, etc are used in the business logic ( java ), which is tightly coupled to a CTI server. The FMS to Java bridge never got released and, in my opinion, is still very limited since it only provides RPC interop. There should be some way to expose FMS's stateful environment to java. My 2 cents is that this sort of enterprise presence/stateful server has probably been scheduled for a new FDS release or some other product in the Breeze family. I am really really stuck here since using RPC to connect both worlds would make the project's complexity grow exponentially. Seems that we would have to make everything live in FMS ( all business logic ) and use it's rpc capabilities only to talk to the external systems ( ldap, cti, etc ), which is almost unnacceptable according to this particular client's standards. Comments really appreciated, Thanks Aldo On 8/29/06, Tom Bray [EMAIL PROTECTED] wrote: Hi Aldo, We have a large, high-usage chat app built with FMS and we spent quite a bit of time investigating FDS as an alternative. My conclusion is that FDS just isn't the right tool for the job. It's adequate for small, simple chat features that you may want to add to some other app (like the dashboard example that ships with FDS), but not large scale chat apps like what we have running on MySpace. Our FMS app relies on being able to dynamically create remote SharedObjects as needed and for clients to dynamically become aware of and subscribe to them (like for user-created rooms). While I was able to figure out how to dynamically create destinations in FDS without using the XML config files, it's not a documented part of the API and I had to do something pretty ugly to provide the destination config xml to the client at runtime. Normally, the destination config information is inserted into the client at compile time, which is a major limitation. You can get around this, but it's kludgy, undocumented, and it may break with subsequent releases of FDS. We also need to be able to manage connections on the server side and keep track of connected clients in a convenient way (like looping through the Application.clients array in FMS). That's really painful in FDS. And push is *much* easier in FMS. We were excited about the idea of moving our server-side logic out of the single-threaded jscript runtime of FMS, but I just kept running into roadblock after roadblock with FDS. I hope that someday FMS or a derivative of it sits on top of FDS to hide some of the complexities of FDS while allowing us to get down into the lower-level workings if we want to. I think FDS is a great solution for a lot of different problems, but it's just not the right tool for the job in our case.

Similarly, a transparent HBox won't show up. You'd have to walk up the parent

[flexcoders] Full Featured Chat with Flex Data Services

Re: [flexcoders] Building a complex chat application on Fx2 FDS
Hi, I have beta3 in my hands now... and I would like a small pointer before getting my teeth into it and see what's changed: how would you go about creating the aforementioned chat application, in particular this part... Basically, I need something analog to the functionality that I would find in these FMS2 features: - application.onConnect() - application.onDisconnect() // this one is problematic... - client.call() - Remote SharedObjects - the ability to keep a reference ( Client Object ) to all connected clients from MessageService??

[flexcoders] Integrating flexunit with flexbuilder2
HI all, As we have it right now ( using Flexunit ) there is a lot of boiler plate code needed to write a testcase, and the separation of tests from the actual classes adds some overhead to refactoring. This is not new, but an old PITA that, in my opinion, is already common enough to be refactored into the workflow. So given that we are changing the way the world engages with ideas and information alltogether, why not take a bold step and integrate unit testing into the IDE? The way I see it, creating a unit test shouldn't even require us to leave the IDE for editing nor execution. Just off the top of my head, to get the debate going. * Edit an actionscript class as I normally would * Open the unit test editor within the IDE ** optionally right click on the outline to indicate scope ( on a method, or just over a class ) * edit just the working code for the tests ( the IDE takes care of relative package management ) * Note that I could also start by creating the test case ( as in strong TDD ) * execute the test by clicking run, or simply on the unit test outline ( which could be somehow integrated with the main outline, depending on the scope of each test ) * The source for the tests is then saved within the very same target source code ( as an interwoven comment, or in the bottom of the class...? ), or on the standard tests/ folder in the package, etc. I know the endeavour is not trivial, but it would surely make the workflow much much faster and straightforward. I mean, if XP is the advocated methodology for Flex RIA dev, why not make TDD an OOTB feature in FlexBuilder.

[flexcoders] Implicit change events for [Bindable] properties? and some notes on ModelLocator
Hi all,
I USUALLY FIND MYSELF REWRITING THE FOLLOWING STATEMENT
snip
[Bindable]
public var selectedItem:ItemVO;
/snip
TO SOMETHING LIKE THIS
snip
private var __selectedItem:ItemVO;
[Bindable(selectedItemChanged)]
public function get selectedItem():ItemVO{
return __selectedItem;
}
public function set selectedItem( v:ItemVO ):void{
__selectedItem = v;
dispatchEvent( new Event(selectedItemChanged) );
}
// I ommited the Event metadata of course
/snip
SO I CAN DO THIS...
snip
MyComp selectedItemChanged=doSomethingThatCannotBeDoneThroughBinding()/
/snip
is there an implicit event that is fired when a Bindable property is changed??
I have digged a little into the generated AS and apparently the
objectChange event is used in general... but Is there a more
granular approach?
As a tangent to this issue.. ( now this is just in case any cairngorm
fella is reading this ), I believe that the ModelLocator should be
wrapp'able as an MXML tag to support inline event handlers... I always
do that with my model locators ( I just call them models though ).
Of course the MXML wrapper would create a new instance, which itself
would be wrapping a singleton. there are some patterns around that (
all of which involve some unwanted boiler plate code and repetition ).
I will post some more on this later perhaps. need some sleep now. good
night ;)
Best,
Aldo

[flexcoders] jrun hot deployment of web-inf/classes ??
Hi all, Is there any way to make jrun autodetect changes to the classes in the web-inf/classes dir? I use ant in eclipse to copy them after an autobuild... and then to restart the server. but this takes way too long. any suggestions? perhaps a way to clean things up and speed up the startup process.

Re: [flexcoders] jrun hot deployment of web-inf/classes ??
Hi Douglas, mmmh tried it out, and jars placed in the web-inf/lib directory are not hot deployed either... perhaps wars are hot deployed... but that's not very useful in my architecture ( i have the server side part in a different project ). unless I use a very complex build of course. What is the recommended way to do this? (avoid restarting jrun with every change to the server side part of a FES app ) Does tomcat support hot deployment in lib/ or classes/ ?

[flexcoders] Flex2: Hierarchical DP with typed objects. Class must be dynamic?
Hi all, I was feeding a tree with a structure of objects ( instances of a custom class, PersonVO ) which had a children array. The tree kept spitting out runtime errors until I modified my class to make it dynamic ( i figured that at some part of the process the tree classes were trying to stick some state variables to the nodes... open/closed flags or similar ). It works now. Is this a bug or an acknowledged restriction?

Re: [flexcoders] Re: State Machine Implementation, anyone?
Hi Cliff,
Yes, Flex2 has a hierarchical state implementation, but it is very
basic. The good part is that it is tightly integrated to the framework
and the IDE.
If we were to build ( or adapt ) a full blown CHSM then integrating it
with the flex state machine should be an objective. Actually, Flex2's
should be easily blended into ours.
Conceptually, the tasks it performs ( property overrides, child
creation, etc ) could be hooked to onEnter and onExit handlers of a
more robust state machine.
Another idea I have been experimenting with:
- We could create an eclipse plugin to work as a monitor and draw the
state chart at runtime. Or we could use the classic LSO connection for
this purpose.
Why not wait till this conversation draws more attention and ideas
before starting something. There might be more than one person reading
around with a deep understanding on the subject.
Best,
Aldo

I will dig it up as time permits and see if a (partial) AS port is feasible.

Re: [flexcoders] Nested faceless components. keeping IDs and DataBinding
Matt,
Unless I have a bug in my compiler(s), I believe I cannot place inline
events in a nested faceless component ( the stack trace is attached at
the end of the mail )
Person name=A id=personA age=55
children
mx:Array
Person name=A1 age=20 talk=trace('THIS INLINE EVENT
WONT COMPILE')/
/mx:Array
/children
/Person
and since I cannod declare an ID on it either, the only way to bind is
by referencing it the long way.
mx:Label text={ 'age=' + Person( personA.children[0] ).age}/
which is not necessarily bad in this simple case but makes you
hardcode the nesting...
See my point?
I was trying to use MXML to create the declaration for a finite state
machine implementation . If I had nesting, events and binding on all
levels then things like declaring transition and entry/exit events
would be very straightforward.
State ... entry=trace('I am the entry action for state ' +
event.target.id ) final=true/
The same with references: instead of passing a string name ( or ID ) I
could just use binding to relate, say, states to transitions
Transition target={aState} execute=Void('another event')/
So, I will have to go for the spaghetti in this implementation for flex15

Aldo

I think we're going to allow nested ids in Flex 2.
For Flex 1.5 though you might be able to make Person an MXMLObject which
would then have its initialized() method called as it gets created.
That call would pass the MXML document which created the object and you
could then attach the person using an id. We have hard-coded id to
not be allowed on deeper faceless objects, but you could use another
name and then just assign that as the variable name for the document.
Something like this:
function initialized(document, id):Void
{
Var myId:String = this['valueYouPicked'];
Document[myId] = this;
}
Now what I don't remember is if when we instantiate via the Array if the
MXMLObject initialized will be called. You'd need to look at the
generated actionscript (turn keep-generated-actionscript on in
flex-config) to be sure.

Subject: [flexcoders] Nested faceless components. keeping IDs and
DataBinding
Hi all,
It would be great to have IDs and databinding available to faceless
data structures.
Unfortunately, there are some restrictions that apply to faceless
components.
Is there any (hacky) way to declare a nested faceless component in an
MXML document and assign a document scoped ID to it ??
This is not legal as there are IDs in the nested components.
c:Person id=foo
c:children
mx:Array
c:Person id=barbie/
c:Person id=birbie/
/mx:Array
/c:children
/c:Person
One ugly way would be to extend a container and do something like the
following
c:Person id=foo
c:Person id=barbie/
c:Person id=birbie/
/c:Person
Now, this limits me to assigning all children to one array... not to
mention the overhead and component-lifecycle-related trouble.
For now the only legal solution is the following I guess...
c:Person id=foo/
c:Person id=barbie parent={foo}/
c:Person id=birbie parent={foo}/
Evidently the benefit of using XML is lost.
Any ideas?

Hi Clint, Man, I was definitely expecting more interest in this one!! so... should I simply presume that Flex is not yet ready to go mobile? Note that I have full control over the version of the installed player in the PDAs ( it is for use within a company ).
