[flexcoders] Will there be a microsoft project like gantt chart in new versions of flex?

[Nate Pearson]

I just asked some adobe people at Apollo Camp but they didn't know. 
They suggested that I explicitly ask the question on flex coders.

So here it is.

Will there be any gantt chart type component in new versions of flex?
Will the scheduler that is in labs be expanded to work as a gantt chart?

Thanks guys, I'm really enjoying Apollo Camp.

RE: [flexcoders] FDS Configuration

[Dimitrios Gianninas]

Correct you can create a Flex app that only uses HttpService and WebService to 
do remote communication. The minute you need to use RemoteObject to call a Java 
class you need FDS. So that means the Flex SWF and FDS have to be within the 
same WAR along with your business side stuff (done in Spring and Hibernate).

You cannot "I would like to deploy FDS in it's own WAR and have multiple Flex 
applications in separate WARs that could all use the same common FDS 
application".

You can however create multiple Flex apps, thus multiple SWFs and have then 
reside within the same WAR along with FDS.

Subject: [flexcoders] FDS Configuration
 
I have the following configuration:

I am developing a multi-tiered J2EE application using Flex, Hibernate,
and Spring.  I am using FDS and have it configured to talk to the
middle tier through AMF.

Everything is deployed in an EAR file and the Flex web application and
the FDS configurations are deployed in the same WAR file.  This all
works great.

I have been reading the documentation and it seems like you can deploy
FDS separately from the Flex web application.  Is this the case? 
Ideally I would like to deploy FDS in it's own WAR and have multiple
Flex applications in separate WARs that could all use the same common
FDS application.

So ideally it would be configured like this:

In an EAR file I would deploy Hibernate, Spring, and a WAR with the
FDS configuration that talks to my Spring middle tier through AMF. 
Then I would have additional WAR files that get deployed separately
that contain all the GUI components and Cairngorm framework that would
use the FDS application.

Is this possible?

Any help or insight on this would be appreciated.

RE: [flexcoders] Cairngorm FrontController

[Dimitrios Gianninas]

You should create your custom component so that it dispatches its own custom 
event. Then whenever that event is dispatch, you can then dispatch the 
appropriate Cairngorm even to perform whatever business logic you wish. That 
will allow you to also intercept which component instance is doing the 
broadcasting.

Subject: [flexcoders] Cairngorm FrontController
 
I am new to Cairngorm and Flex (I'm All About Flash) so bear with me.

I am creating a component and I want it to use Cairngorm. I also want 
to be sure that some events fired from the component are only heard 
by the Cairngorm of the single component instance. Component 
namespaces won't help because I use multiple instances of the same 
event, I could probably filter by instance, but I am trying not to 
hack (you'll probably see the irony after the next sentence...

If I use Cairngorm as is... ...and I utilize the Singleton 
CairngormEventDispatcher, as soon as I put two instances of a 
component on stage, the events from one instance cause the front 
controller on the second instance to fire those events 

Sadly this is probably operator error.

Though I am guessing that someone has had this problem before and 
surely there is a best practice solution to this already, I thought I 
would spend a little time to explore the issue further and find my 
own solution.

I decided to try to handle this by using separate instances of the 
CairngormEventDispatcher (MyViewHelper.dispatcher) for each instance 
of my component. Then I could inject that dispatcher into 
MyFrontController when it is instantiated so that it knows which 
dispatcher to call. 

Just when I think I am on to something, I had to override addCommand 
so that it would add an event listener to that instance instead of 
the Singleton CairngormEventDispatcher. This is great but it required 
two modifications (minor, yet still modifications) to the Cairngorm 
FrontController class in order to compile my creation. (see snippets 
below) Basically I took two private things and made them protected.

Of course this might effect other pieces I have yet to build, but my 
level of mastery coerces me into believing I have found a solid 
answer.  If those iteration two guys were really geniuses 
they would have made these protected in the first place. 

Ha, ha, ha, just kidding, (I crack myself up)

So I can either use my own FrontController impl or I can ask the 
question: Is this a bug in Cairngorm? Or am I correct in beleiving I 
must be doing something wrong...

Some code samples:

//
// myViewHelper Snippet:
//
public function MyViewHelper(view:Object)
{
dispatcher = new CairngormEventDispatcher();
controller = new MyFrontController(dispatcher);
...
}

//
// myFrontController Snippet:
//
public class MyFrontController extends FrontController
{

private var dispatcher:CairngormEventDispatcher;

public function MyFrontController(dispatcher:CairngormEventDispatcher)
{
  super();
  this.dispatcher = dispatcher
  ...
}

public override function addCommand( commandName : String, 
commandRef : Class ) : void
{
if( commands[ commandName ] != null )
{
throw new Error( "Command already registered for " + commandName );
}
commands[ commandName ] = commandRef;
dispatcher.addEventListener( commandName, executeCommand );
}
}

//
// Cairngorm FrontController Mods
//
public class FrontController
{
// ST - 03/15/2007 : private var commands : Dictionary = new 
Dictionary();
protected var commands : Dictionary = new Dictionary();

// ST - 03/15/2007 : private function executeCommand( event : 
CairngormEvent ) : void
protected function executeCommand( event : CairngormEvent ) : void

...

}

[flexcoders] Re: What to do on the server, what to do in Flex?

[Paul DeCoursey]

Yeah, the flash player isn't going to have much trouble with most of
what you can throw at it. We have our clients doing a lot of work, but
our servers still do all the heavy lifting. If we ever send XML to the
client anymore it's for AJAX things outside of flex or it's SOAP
requests. Objects will almost always be a better choice.

There are a lot of things that we just won't do on the client, like
text indexing or any other heavy processing unless the user expects
it.  Generally that violates those unwritten social contracts about
what online services can or should do on the client.

[flexcoders] keeping server object relationships

[dgigon]

Hi everyone,

Here is a simple design question on which I'd like to have your opinion :

made short : "How to keep server object relationships in flex when you do 
several 
calls"


Take an example :

2 companies, say Apple and Microsoft, have several clients, among them, 
say Macromedia. (relation Company->Client)
Let's make a flex application which requests (server call) and displays 
all the clients of a selected company.

If I make a first remote call to get Apple's clients, Flex will receive a list 
of objects including an 
Client object for Macromedia.
Later, I select Microsoft, and get Bill Gate's clients. Flex will receive 
another list of objets, including another version of the
Client object for Macromedia.

Although it is the same Macromedia client object on the server, I have now 2 
distinct Macromedia client object in my Flex Application.
And if, for example, I change the name of one Macromedia object to (purely 
fiction) Adobe, the change won't apply on the other objet ...

[flexcoders] Re: Simple design question

[Paul DeCoursey]

I'm confused as to what the goal is.  There are already mxml tags for
HTTPServices so that can already be defined in a non-visual way in
mxml.  Just put that definition in the main application.

If all they need is a container for non-visual components that is
itself a non-visual component, then just create one that extends
IMXMLObject that accepts any other IMXLObjects as children.

But really, I would recomend doing as much as possible in AS anyway. 
AS is going to compile faster so your build times will be shorter.  AS
code is easier to debug.  And expanding ActionScript skills will only
help you be a better flex developer.

Paul

RE: [flexcoders] What to do on the server, what to do in Flex?

[Tracy Spratt]

For sure the client/Flash Player can handle whatever you need it to.
The Flash Player is extremely fast at non-visual processing. We have
packed incredible amounts of logic into the client, I'm talking 30,000
plus lines of code.  Most is not visual, but that much code does take a
bit of time to DL the first itme.  But once it gets to the client
response is lightning fast. FP7 was fast FP8+ is 30% faster

 

So don't sweat the client capability.

Whenever I consider something like this I try to put it in persective and

- ease of implementation (coding time)

- flexibility for reuse in other projects

And then make my decision based on this. I know it's probably not the answer

RE: [flexcoders] FDS Configuration

[Jeff Vroom]

So it sounds like you just want to put the FDS jar files at the EAR
level of your J2EE application.   That is possible with some caveats.
In 2.0.1 if you do that, the classes mentioned in your
services-config.xml file also have to live in the EAR level.  FDS uses
the class loader uses to load its classes to load any remote object
destinations, assemblers, etc.   I'm also not sure if the "web tier
compiler" also can be moved into the EAR level.. you might want to leave
the flex-webtier jar files where they are in the WAR and just move the
flex-messaging jars into the EAR level.  

 

One other thing is that if you have more than one WAR file which define
MessageBrokerServlet instances in this EAR, you'll end up creating
multiple message brokers, one for each web application.  Each message
broker will only support the destinations in its flex configuration.
But if you are going to have more than one MessageBroker, the second and
subsequent MessageBrokerServlets need an additional init-parameter the
"messageBrokerId".  This is just a string you use to identify that
MessageBroker.  If you use any of the static lookup methods to say push
messages to flex clients, you need to specify the message broker id in
those calls so you get the right one. 

 

In 2.5 (currently in beta) we have added the ability to specify a
different class loader so an FDS application can be made to refer to
classes which live in the WAR level.  There are some tricks to making
that work so if you need that for your use case let me know.

 

Jeff

and Spring. I am using FDS and have it configured to talk to the
middle tier through AMF.

Everything is deployed in an EAR file and the Flex web application and
the FDS configurations are deployed in the same WAR file. This all
works great.

I have been reading the documentation and it seems like you can deploy
FDS separately from the Flex web application. Is this the case? 
Ideally I would like to deploy FDS in it's own WAR and have multiple
Flex applications in separate WARs that could all use the same common
FDS application.

So ideally it would be configured like this:

In an EAR file I would deploy Hibernate, Spring, and a WAR with the
FDS configuration that talks to my Spring middle tier through AMF. 
Then I would have additional WAR files that get deployed separately
that contain all the GUI components and Cairngorm framework that would
use the FDS application.

Is this possible?

Any help or insight on this would be appreciated.

 

[flexcoders] What to do on the server, what to do in Flex?

[Kevin]

I have a continuous debate with myself about what to accomplish with  
server code and what to accomplish internally with FLEX.   My  
decisions currently are mostly based on my skill level in each  
language and which language makes the process the easiest. However, I  
am wondering if there are better reasons to make these decisions.


For example, if I am going to gather some XML data...should I?

1) Load the XML directly into Flex (URLRequest) and then convert the  
XML to objects in Flex.


2) Load the XML in PHP and then convert to PHP objects and send to  
Flex (AMFPHP).


For some reason, I lean towards doing all parsing and object  
translation on the server and only sending objects back and forth to  
Flex, however, I don't know if this is because of my experience with  
Flash RIA's that use to often get stuck in timeout loops.  On the  
other hand, I have a friend who always says "anything you can do on  
the client, do on the client..."  Conceptually, I understand this,  
but in real life I don't know how this plays out.  My thinking is  
usually that the flash player is more limited that the server.


Anyone have any thought about this?  I would say my apps generally  
fall in the middle of the spectrum.  They don't deal with millions of  
records or millions of users, but they also are not small single user  
widgets.


Thanks for your insight.

RE: [flexcoders] FlexFactory/FDS Inconsistencies

[Jeff Vroom]

Hi Harris,

 

You really should be able to just add code which looks into the
properties map in your FlexFactory implementation's
"createFactoryInstance" method.  This should be called at startup time
when the system is parsing the configuration.   It is important to
access the configuration variables here even if you don't use them until
the lookup method because FDS will complain if there are any config
variables defined which are not accessed at startup.  (As an aside, the
ConfigMap interface has an "allowProperty" method you can use to mark a
config entry as being expected even if you don't need it until later).  

 

As a sample, I modified the createFactoryInstance method for the spring
factory as follows and was able to see the config variable printed on
startup:

 

public FactoryInstance createFactoryInstance(String id, ConfigMap
properties)

{

SpringFactoryInstance instance = new SpringFactoryInstance(this,
id, properties);

System.out.println("myvar=" +
properties.getPropertyAsString("myvar", null));

instance.setSource(properties.getPropertyAsString(SOURCE,
instance.getId()));

return instance;

}

 

I was using the 2.5 beta but this should work also in 2.0 and 2.0.1.
Also make sure you take a look at the EJB Factory which is up on the
adobe component exchange if you haven't already.

 

Regards,

 

Jeff

Subject: [flexcoders] FlexFactory/FDS Inconsistencies

 

Hi there. I am working on a FlexFactory implementation that is capable 
of creating objects that act as remote services. In the documentation 
it states that, "Each factory instance can add configuration attributes 
that are used when that factory instance is defined, as the following 
example shows:



mypackage.MyRemoteClass
myFactoryId

myfoobar2value




However, adding an extra element to the properties element within 
remoting-config.xml causes Flex to chock in the initialization process 
when starting the server.

Is is possible to get additional information into a FlexFactory to 
customize its implementation? I've looked in detail at the example 
that does this with Spring, but it doesn't take advantage of passing a 
custom value to the FlexFactory. I am trying to deploy this to 
Weblogic and create a FlexFactory that is capable of creating EJBs based
on their JNDI name.

thanks,

Ok, more detail:

Create an mxml application, named, say "Base.mxml":





  [vars, functions, getter/setter, any as functionality, for example:]

  [Bindable]public var sMyString:String = "somestring";





 

Then create the UI mxml file:







 

The lable will display "somestring".

[flexcoders] Firefox - FileReference.upload and HTTPService do not share sessions/cookies?

[pgp.coppens]

Flex fans,

I am struggling with the following scenario

1. Use an HTTPService POST to authenticate to a servlet backend (works
fine)
2. Use HTTPService requests to the same server and rely on previous
authentication (works fine)
3. FileReference.upload with IE also picks up the same session cookie
and thus uses the authenticated (and authorized) session. With Firefox
or Opera however, a FileReference.upload request does not seem to pick
up the same JSESSIONID cookie and therefore fails as it is not
authenticated/authorized.

Does anyone know how to deal with this? How should one normally use a
FileReference.upload to a servlet server that requires authentication?

Any help or guidance warmly welcomed!

[flexcoders] Re: Cairngorm FrontController

[Shannon]

Thanks for throwing me a line, like I said im new... I guess John 
Mark was one of those guys that never had to ask questions. he's 
cooler than me for sure. (btw any helpful/ unhelpful/ thoughts/ 
blasts/ etc are completely appreciated) For the record I would rather 
not "muck" with Cairngorm.


> I think when Shannon is talking about components he's talking 
about modules in fact. In that case, each module has its own 
controller. In that scenario, if you dispatch an event and that event 
(same event type) is registered in two different modules, the two 
commands in different modules will be fired.

You rock! You totally get it! 

I agree that passing target/unique/random instance identifiers and 
then filtering on that identifier before acting on a cairngorm event 
is probably the best solution, but I really feel like im hacking. In 
fact I am guessing that cairngorm never was intended to handle this, 
and the discussion can probably stop here, but I would greatly 
appreciate it if someone can flush out my ignorance and tell me that 
cairngorm was either never designed to handle this or (I can dream) 
that it has some elegant solution? 

For the sake of John Mark, here is a use-case that emphasizes the 
problem, hope it helps: 

1. Each Component works as stated above, a single ViewHelper 
encapsulates the components behavior in a well recognized/documented 
Cairngorm fashion. 

Am I on the right track so far?

2. A. Component A is a checkout page that asks the user to fill in 
billing and shipping information. It contains two instances of 
Component B (a cairngorm address entry component) as Billing and 
Shipping forms*.

3. Component B (Instance 1 (Shipping Information)) contains field D 
(zip code)

4. Component B (Instance 2 (Billing Information)) contains field D 
(same component, new instance)

5. User fills out shipping information (noticing the billing 
information is updating because of the ties to cairngorm 
architecture) Thinks this is cool. 

6. user moves on to billing form and selects "90201" from a list of 
zip codes in the billing form.

7. ViewHelper dispatches CairngormEventDispatcher.getInstance
().dispatchEvent(zipChangedEvent);

8. FrontController is listening to this event for both forms and 
fires the UpdateAddressFormCommand (twice, once for billing and once 
for Shipping [hopefully you recognize the problem at this point])

8. The updateAddressFormsCommand sees the information for that zip 
code is cached locally (let's stave two calls to the server) and 
overrides the users entries for the shipping information while 
updating the billing information. 

9. User is very sad and closes the browser.

In the end I am looking for a solution that will help me adopt 
Cairngorm in my organization (without trying to change it. Trust me 
when I say I would really rather understand than override) 

I just want to learn to this and do it their way. 

*  in my component and two 
component instances in an application causes an error because only 
one instance of the Helper with id="helper" is allowed. Instantiating 
this using AS3 within a script tag works because (I think) it isnt 
being instantiated as intended.

What is the best way of getting the body segments into flex? At the

[flexcoders] question about colopicker dropdown

[camlinaeizerous]

I'm currently working on a miniature sized flex app and I have a
couple color pickers however there is a issue of them being cut off by
the applications boundaries. Is there a simple way to spawn the popup
at a different location then underneath the button?

[flexcoders] using VideoEvent.COMPLETE

[Seizo Mazer]

Hi everyone. My application is working almost the way that I want it to 
but I'm having some difficulty. I have a datagrid, which has some song 
information, and a videodisplay. The video clip is shorter than the song 
so when I play both together, I want the song to stop when the video 
clip stops. Here is my code that's in the script block. What do I need 
to do make this work? Thanks,

Seizo

import mx.events.ListEvent;
import mx.events.VideoEvent;
   
import flash.media.Sound;   
import flash.net.URLRequest;
import flash.display.Sprite;
   
private function itemClickEvent(event:ListEvent):void {
   
var 
selectedSongURL:String=event.currentTarget.selectedItem.songURL;
eventType.text=selectedSongURL;
var _sound:Sound = new Sound();
var soundFile:URLRequest = new URLRequest(selectedSongURL);
_sound.load(soundFile);
vidTB.stop();
vidTB.play();
_sound.play();
_sound.addEventListener(VideoEvent.COMPLETE, soundStop);
}
public function soundStop(event:VideoEvent):void {
event.target.close();
}

[flexcoders] Re: select some items only

[Paul DeCoursey]

I have the same problem except in a datagrid.  I eventually gave up
because I could not find a solution. I'll admit I didn't spend much
time on it, a few hours maybe.  My initial idea was that I could
preventDefault on the itemClick event and that would stop it from
being selected, but that didn't work.  I also tried to update the
selectedItems removing the items that I didn't want to allow selection
on, and that failed.  I was hoping to look at it more next week, I had
a deadline today and had to move on to more important things.

[flexcoders] select some items only

[metalbeard]

Hi There,

Is there any way that we can disable the selection for only some
specific items inside a tree.

Am trying to make the selectable property of the tree =false when the
mouse rolls over the unwanted item then make it ture when it is rolled
out but that didn't work.

Do you have any ideas?

If you use the Cairngorm Microtecture then you do use a 'faceless'
MXML based component everytimee: your subclasses of the
FrontController.  The same thing applies to things like validators
which are not view-type classes.  You instantiate them via mxml
oftimes but they are not included in the displayList of the housing
container.

[flexcoders] FDS/CF behind IIS Still?

[Travis Young]

With Flex 1.5, Macromedia strongly advised to use IIS (or similar)  
and connect to Flex and CF via an ISAPI gateway.  This worked well  
and leveraged IIS for security models and SSL.

It looks like FDS (for data services at least) does not work in this  
manner and the Flex app talks directly to the FDS server on port 8301  
(or whatever) and FDS can have its own internal security model.

If all of your data access is via FDS, does it make any sense to put  
CF behind IIS (or similar) or just let FDS talk directly to CF on  
port 8300 (or whatever)?  This works in a development environment,  
but is it the best practice for production?

If Flex does talk to directly to FDS on port 8300 (or whatever)  
through JRun (or whatever) is it possible to utilize SSL?

RE: [flexcoders] Simple design question

[Tracy Spratt]

I wish we had a "faceless" mxml component specifically for this kind of use.

 

I use an Application tag to implement my functionality, then use that component 
as the root tag of the application.  Some folks call this the "code behind" 
technique.

 

You could also use a canvas, which is the lightest container I know, and set 
height and width to 0 and visibility=false.

 

Also, there are a few faceless mxml components.  Would it make sense in your 
case to extend one of them?

My button renderer listens for the click event and then dispatches a 
custom event containing the row data and the renderer's configured 
action string. I guess there could be a cleaner way of doing this 
(overrinding the button's clickHandler method?) but I must admit that

[flexcoders] FlexFactory/FDS Inconsistencies

[Harris Reynolds]

Hi there.  I am working on a FlexFactory implementation that is capable 
of creating objects that act as remote services.  In the documentation 
it states that, "Each factory instance can add configuration attributes 
that are used when that factory instance is defined, as the following 
example shows:



mypackage.MyRemoteClass
myFactoryId

myfoobar2value




However, adding an extra element to the properties element within 
remoting-config.xml causes Flex to chock in the initialization process 
when starting the server.

Is is possible to get additional information into a FlexFactory to 
customize its implementation?  I've looked in detail at the example 
that does this with Spring, but it doesn't take advantage of passing a 
custom value to the FlexFactory.  I am trying to deploy this to 
Weblogic and create a FlexFactory that is capable of creating EJBs based
on their JNDI name.

thanks,

I might agree with that, but in Firefox this is not an issue. Firefox

until I exceed the physical memory on the machine.

BTW: I posted the wrong sizes in my original email. The images we are 
dealing with are 256Meg to 600Meg and the application will get up over 
2.5Gig and then free up memory. I have 2Gig of physical ram in my

[flexcoders] Re: memory keeps increasing when RemoteObject is used

[vargaandrea]

Thanks,

I've tried in IE under wine, and it uses less memory, then in Firefox
(not under wine), so you are right, but my problem is not the amount
of memory used, at least not when the application starts. The problem
is, that it takes more and more memory, so if I leave even this little
test running in the browser (having the button clicked a couple of
times), in a couple of hours my system crashes, at least Firefox does.

(btw, I'm not using FDS)

[flexcoders] Re: Runtime Memory Problems

[One Person]

I might agree with that, but in Firefox this is not an issue. Firefox 
releases memory on a regular basis while IE7 does not seem to release 
until I exceed the physical memory on the machine.

BTW: I posted the wrong sizes in my original email. The images we are 
dealing with are 256Meg to 600Meg and the application will get up over 
2.5Gig and then free up memory. I have 2Gig of physical ram in my 
machine.

I didn't think I needed a crossdomain file if the FDS server and CF server

Well, when I copy the service tags from the services-config on my CF server 
(which works) to the services-config on my FDS server, I get the following 
in the FDS console window...

03/16 12:40:25 error Could not pre-load servlet: MessageBrokerServlet

'coldfusion.flash.messaging.ColdFusionAdapter'.

but... if I change the adapter type from the 
coldfusion.flash.messaging.ColdFusionAdapter to the
flex.messaging.services.remoting.adapters.JavaAdapter I get "cannot create 
class of type transfer_center.cf.transfer_center" returned in the RO call's 
event.fault.faultString (the path to my CFC is

Can't you use the ColdFusion adapter when the Flex client is compiled and

[flexcoders] CursorManager, PopupManager - internal state across module load?

[david_mccraw123]

Hi,

I've run into an issue where, after loading a module, calling
CursorManager.setBusyCursor() inside that module causes an exception
(Error #1009: Cannot access a property or method of a null object
reference). The same happens with Alert.show (in
PopupManager.createPopup).

First I moved the setBusyCursor() call into a button click(), to be
sure the module had loaded completely - but this had no effect.

If, however, I call setBusyCursor() then removeBusyCursor() in the
/module loader/ mxml file (on ready event), the module button can then
also set the cursor without error. Similarly, an Alert in the module
loader (on ready event) allows alerts within the module.

To muddy the waters further, if I load the module at the start of the
application, it works okay - it's just when I re-load it that the
error starts occurring.

I was hoping someone might have run into a similar problem, or have
any pointers toward finding a solution.

Thanks,

Dave

[flexcoders] Fascinating problem hiding columns in a DataGrid

[Peter Demling]

While a problem for me, I find the following behavior fascinating and
inexplicable; so here's a good challenge for any Flexlock Holmes out
there (full code is below - 26 lines, fairly simple):

I have a DataGrid that's using a RemoteObject as its dataProvider, and
I initialize the 'visible' propery of its first dataGridColumn to
"false".  On startup, this column (labelled "Name") is hidden - so
far, so good.

Next I click my "GetData" button to invoke the RemoteObject's service,
and poof!  The column becomes visible - even though the debugger
verified that its visible property remains false!

So now I click my "HideName" Button, which forcibly sets the visible
property of this "Name" column to false.  The debugger verifies that
its false before I click it, and its false after I click it.  Still,
the column remains visible.

So just for the heck of it I click my "ShowName" Button, which
forcibly sets the visible property of the "Name" column to true.  The
debugger verifies that the value is changed to true - and as an added
bonus, it increases the width of the Name column from 50 to 100!  Okay...

Finally, I click the "HideName" Button, and *this* time it works - the
Name column is now hidden, having worked only after I forced its
visible prpoerty to true immediately beforehand.

I can replicate this ad nauseum (calling the RemoteObject service
makes the hidden column visible without setting visible to true;
forcing the visible value to false works only after forcing it to
true), but it only happens when the dataProvider is remoteObject, and
the forcing of the visible value only shows the column when done via
Buttons (it does not work directly in code right after calling the
RemoteObject service).

Full code is below.  I tracked every single Name column variable
through the debugger, and nothing changes, except for visible and
width as noted above.  I did track down the moment that the "ShowName"
button expands the column width (in Button.as, line 2050, function
focusOutHandler), but I don't know enough about Flex yet to know why
that would enable column hiding; or why the call to RemoteObject is
revealing my invisible column in the first place, for that matter.

Started out just wanting to hide some DataGrid columns, but went
pretty far down the rabbit hole.  Thanks for any input!

Re: [flexcoders] Viewstack and passing variables to children

Gordon,
This is EXACTLY what I was looking for to get the button to link to  
the other child page.  Thank you s much for posting that.


Doug,
I see what you are saying, but I'm so new to Flex and I didn't come  
over from Flash Dev. so I'm really not that hip on ActionScript.  If  
someone could provide a little more assistance, that would be so  
awesome.


Here is what I've gotten so far (and I'm not sure if any of it is  
correct):


On JobSearch.mxml I set this up:

[Bindable]
public var job_id:Number = currentJob.job_id
(I'm hoping that'll assign the job_id variable the job_id of the  
current selected job)


On Timeline3.mxml I set this up:

[Bindable]
public var job_id:Number

I am not sure how to use the DataBinding to hook up the two.

Thank you in advance for further assistance to us ignorant newb Flex  
Coder posers.  :-)

I'll agree that an event dispatching method is sort of the

you could have a bindable public variable named job_id in both your  
JobSearch and Timeline3 components and then use data binding to  
bind the job_id in Timeline3 to the job_id in JobSearch. So that  
way whenever it's updated in JobSearch it will get updated in  
Timeline3.

But you could also use application.Application.timeline3.methodName

I've been looking all day and can't find a solution to this -
although I'm sure it's very simple.

I have a main application that I'm using a ViewStack in:






This works great. :-)

The JobSearch.mxml page has a button that when you click on it, I
want to take the job_id variable I've declared and pass it to the
Timeline3 page and have that page as the main page.

If I put the button on the main.mxml page, everything works fine
(except for passing the variable, but it will at least change the
page)... but if I put the button on the JobSearch.mxml page it
doesn't work. I guess I don't know the syntax for doing that.

If someone would help me with the syntax to link from one child to
another, when the children are their own mxml pages I would be s
appreciative.

Thanks!

[flexcoders] Passing different dataFields to the same itemRenderer component

[missgiggygirl]

Hello helpful people! :)

I have a datagrid that is populated by an external XML file.  Some of
the cells have various icons in them.  I am using an itemRenderer to
insert an image in the first column.  However, I do not know how to
use this same itemRenderer/component for the other images, because the
component currently has the dataField "hardcoded".  I need a way to
re-use this itemRenderer/component so that whatever dataField if being
used passes itself to the component dynamically.

This sounds confusing, but it isn't.  Here are the two important snips
of code:

FROM mainmxml 
--






 


FROM IconRenderer.mxml
--

http://www.adobe.com/2006/mxml";

I am sure there is an easy way to make a function here, but I just
don't know how.

[flexcoders] FDS Configuration

[mister.kotter]

I have the following configuration:

I am developing a multi-tiered J2EE application using Flex, Hibernate,
and Spring.  I am using FDS and have it configured to talk to the
middle tier through AMF.

Everything is deployed in an EAR file and the Flex web application and
the FDS configurations are deployed in the same WAR file.  This all
works great.

I have been reading the documentation and it seems like you can deploy
FDS separately from the Flex web application.  Is this the case? 
Ideally I would like to deploy FDS in it's own WAR and have multiple
Flex applications in separate WARs that could all use the same common
FDS application.

So ideally it would be configured like this:

In an EAR file I would deploy Hibernate, Spring, and a WAR with the
FDS configuration that talks to my Spring middle tier through AMF. 
Then I would have additional WAR files that get deployed separately
that contain all the GUI components and Cairngorm framework that would
use the FDS application.

Is this possible?

Any help or insight on this would be appreciated.

RE: [flexcoders] Cairngorm: When / why override clone in Events

[Piotrowski, John]

Sean,

 

I recently had a project that I had to implement the Clone Method when
defining a custom cairngorm event.  I downloaded the source code to the
flex 2 Cairngorm store and looked at how they were doing the custom
events.  In that project the clone event was simply creating a new
instance of the Event.  So if your custom event class was defined as
public class GetProductEvent extends CairngormEvent with a public var
ItemID:int, the clone method was return new GetProductEvent();

 

I created all of my custom events in this manner and initially had no
problems dispatching my events and assigning my event the ItemID.  

 

But then I ran into a problem.  In my app I wanted to save the last
attempted event in case the user's session has timed out.  If a user
times out, I wanted to re-dispatch the event once they log back in.
This was important in my app because users could be doing a lot of
things in the Flex App without ever hitting the Coldfusion server, but
then they would lose all their work when they went to save.  Since the
Coldfusion server would have timed them out after 20 minutes.  

 

So I created a model variable tempPendingCommand:CairngormEvent and
would assign the custom event to this variable before dispatching it.
After the event is successful I clear this variable out.  Upon testing
this approach, I noticed my data (ItemID) was null when the event was
fired after a timeout and successful login.  It took a while to track
down in the debugger and it came down to the Flash.Event Clone method.
The override clone method I defined had no idea there was an ItemID.
Luckily, the fix was easy.  I changed my GetProduct clone method to;

 

Var tempGetProductEvent = new GetProductEvent();

tempGetProductEvent.ItemID = ItemID;

return tempGetProductEvent;

 

This solved the problem.  So it seems it is only an issue if you try
caching or assigning your custom event to another variable.  If you are
directly dispatching the event, the clone method is never used, at least
in my case.

Sean,

You can read in the Flex doc:

There are two utility methods in the Event class. The clone() method
allows you to create copies of an event object. The toString() method
allows you to generate a string representation of the properties of an
event object along with their values. Both of these methods are used
internally by the event model system, but are exposed to developers for
general use. For advanced developers creating subclasses of the Event
class, you must override and implement versions of both utility methods
to ensure that the event subclass will work properly.

Nothing to do with Cairngorm.

Rgds,

Olivier

In one of the Cairngorm examples I learned Cairngorm from each event had
defined an override for the clone method (of Flash.Event). Does anyone
understand haw and when you should do this? Does Cairngorm clone the
events behind the scenes somewhere that requires this be done?

Re: [flexcoders] Wondering why ArrayUtil.getItemIndex() loops through Array Items instead of using Array.indexOf()

[Troy Gilbert]

And furthermore, what's the point of having that method? I would assume the
point of a util function would be to aggregate several common steps, but it
seems to me like they just changed name?

Array.indexOf() == ArrayUtil.getItemIndex() (functionality-wise)

So, what's the deal?

Troy.

[flexcoders] Re: Simulating "clicking the X" of a TitleWindow

[Derrick Grigg]

Have the window dispatch the close event, you can do this from
anywhere, you just need a reference point to the title window you want
to dispatch the event.

ie. in the code inside the TitleWindow instance

var e:Event = new Event(Event.CLOSE);
//parent is a reference to the parent title window instance
parent.dispatchEvent(e); 

You can also 'bubble' the event up from any child within the title
window instance and it will have the same effect. 

var e:Event = new Event(Event.CLOSE, true);
dispatchEvent(e); 

Only listeners to that specific title window instance will hear the
close event, not listeners to other windows.

[flexcoders] ControlBar on Panel not positioned correctly when added from ActionScript

[scott_flex]

This should be simple but i'm fighting the position of a ControlBar 
that's on a Panel control when add via actionscript, not mxml.

The control bar is not correctly displayed at the bottom of the panel.  
IE... if the other child components cause the scroll bars to appear, I 
have to scroll to view the control bar as well... it should be always 
visible and stationary.

This works properly if i add the control bar in with mxml as the last 
element but not when using actionscript... even if i add it via 
actionscript in the creationComplete of the panel  to ensure it's the 
last child added.

[flexcoders] Re: Trace Output Stopped Working

[Paul Whitelock]

I think I've figured out how to fix the problem. I first quit Eclipse
and deleted the .metadata folder in my workspace after first making a
copy of it. Next I restarted Eclipse and imported my project (Eclipse
was reset to it's default workspace without the metadata). I tried
debugging the project and trace statements started working again.

I next quit Eclipse and tried copying all of the subfolders in the old
.metadata directory that I saved except for the com.adobe.flexbuilder
subfolders back into the live workspace. When I restarted I was back
to my old configuration and trace was still working.

There must be something in those com.adobe.flexbuilder subfolders that
caused the problem, but I don't know what it is or why it caused the
trace statement to stop functioning. Anyway, it was a lot easier to
fix the problem this way than the other way of re-installing the whole
development environment ;-)

Awesome! Thank for the answer, I have been banging my head against

[flexcoders] My first Flex experiment. Styling weirdness.

[Matthew Hayes]

Hello all,

I built my first Flex page the other day.  I must say, everything  
went really smoothly except for one thing.  I was trying to style a  
ToggleButtonBar.  I even got the styling code from the Style Explorer  
app... where it seemed to work just fine.  Here's the code:


ToggleButtonBar {
   horizontalGap: -1;
   buttonStyleName: "nhButtonBarButton";
   firstButtonStyleName: "nhFirstLastButtons";
   lastButtonStyleName: "nhFirstLastButtons";
   selectedButtonTextStyleName: "nhSelectedButton";
}
.nhButtonBarButton {
   highlightAlphas: 0, 0;
   fillAlphas: 1, 1, 1, 1;
   fillColors: #ff5f37, #ff5f37, #ff, #ff;
   borderColor: #ff5f37;
   themeColor: #ff5f37;
}
.nhFirstLastButtons {
cornerRadius:20;
}
.nhSelectedButton { 
}

The really weird thing is that the horizontalGap style is taking, and  
so is the cornerRadius style in the .nhFirstLastButtons class.  
However, nothing from the .nhButtonBarButton is working!!   
Eventually, I just gave up, moved on, figured I'd get to it later...  
well, it's later.  Any help?


Thanks!

RE: [flexcoders] Runtime Memory Problems

[Alex Harui]

GC is opportunistic.  This means it does not run all of the time.  It
tends to be triggered by allocating memory instead of freeing it, so
watching an idle app will almost never result in GC.

 

A good test is to cycle between two images 1000's of times and see if
memory usage is unbounded.

Subject: [flexcoders] Runtime Memory Problems

 

Description:
We are creating a web-app built with Flex 2.
This app uses some very large image files (From around 256K to over 
600K)
We have an image viewer section of our Flex app that will allow the 
user to move from one image to another.
I was noticing that with our app in IE7 that memory useage would 
climb each time we grabbed a new image but even after letting it set 
for several minutes the memory usage would not go down. It was acting 
as if Garbage Collection was not getting called. So I added all kinds 
of code to make sure that we were letting go of the previous images 
to allow Garbage Collection to work.

After 3 days of trying to track down the problem I decided to create 
a smaller Flex app that only used our image viewer control to limit 
the number of variables in the problem. After a few hours I still 
could not figure out the problem so I replace our image view with a 
standard  tag. The problem still existed after doing this. 
Having take our code out of the picutre I decided to compare results 
in FireFox. FireFox would Garbage Collect fairly quickly and the 
problem did not seem to exist using my test Flex app in FireFox.

>From what I can tell, IE7 and Flash (version 9.0.28.0) do not seem to 
work well at allowing Garbage Collection to work.
I have the same version of Flash installed in FireFox 2.0.0.2 and 
there does not seem to be any problem there.

The code below is what I used in my mxml file. To test it you will 
need to point to some kind of large images that you have access to. 
The images that I was using are on an internal network and so are 
unavailable to anyone on the outside.

I can't find a way to post my images so I hope this description is 
good enough.

In IE7 the memory would climb each time I would move to the next 
image. On the left of this graph I loaded several images and then let 
IE7 sit. After a few minutes, and memory staying where it was, I 
continued click next to load images. Only after I hit a saturation 
point (Around 2.5Meg) would it Garbage Collect. My machine has 2Gig 
of Ram.

The next rise in the graph is where I kept loading images over and 
over until the memory usage was about the same as just before the 
garbage collection happened the previous time. I let that sit for a 
while and then tried to load one more image. That caused the garbage 
collection to happen.

The next 4 peaks in the graph are where I basicly clicked on the next 
button over and over as fast as I could and the Garbage Collection 
seemed to happen a little more often.

In FireFox I ran similar tests of loading images and waiting in 
FireFox. The Garbage Collection seems to be working fairly well here. 
Each time I would load a new image the previous one would be cleaned 
up with garbage collection.

So I'm not sure what can be done or if there is a fix for this. I 
really would LOVE to have access to the Garbage Collection in Flash 
so I could force things to happen when I am dumping a real large 
image.

Re: [flexcoders] memory keeps increasing when RemoteObject is used

[Rich Tretola]

I have found that the FDS server is greedy and it will take as much memory
as you have to offer.

For example:

I have an application that shows 300 mb of ram being used by my Firefox
browser on Windows XP with 2 gb of machine ram.

The same application runs at only 90mbs of ram on a Windows XP machine that
has 500 mb of system ram installed.

Try running your app on an older machine or a virtual machine to see how
much ram it uses.

It has a timer that keeps updating a label with

Now, if you start the demo, you can see that totalMemory stays the

[flexcoders] Re: Simple form submit example

According to Ben Forta this is what I need.

1) Create a ColdFusion CFC method which accepts a record to insert, 
either a struct with properties or just a list of arguments.

DONE
 
2) Define a  connection to the CFC.

DONE
 
3) Create your form in Flex. The click event on the form button 
calls an AS function.

FORM LAYOUT DONE, but not AS.
 
4) That AS function does any validation, and then calls cfcObj.method
() passing it an equivalent AS class or the values comma delimited.


What I still need help with is the AS to tie the onclick in the 
button, to an AS function, then passing the form data to the 
remoteobject.

Probably pretty easy AS, but I'm just trying to learn AS. 
Conceptually, the process is clear, but I need to see a generic 
example of the syntax. Here is portions of the code so far:


function sendFormdata(){
???
}


















I'd appreciate any help pulling these three parts together.

Re: [flexcoders] Runtime Memory Problems

[slangeberg]

Only after I hit a saturation
point (Around 2.5Meg) would it Garbage Collect. My machine has 2Gig
of Ram.



You're worried about a Flex app using 2.5MB memory? That's nearly nothing.
I've seen apps use upwards of 100M, and that's still not much compared to
2GB.

If you look at the articles online and perhaps posts within this list,
you'll see that there are indeed thresholds within the player, to kick in
garbage collection, but in this instance, i don't see the issue.(?)

RE: [flexcoders] tutorials for writing custom classes

[Stephen Gilson]

There are several places that you can start. From the Flex Dev Center,
try the 4 Quickstarts on creating components:

Subject: [flexcoders] tutorials for writing custom classes



Are there any good tutorials someone can point me to for writing 
custom Flex classes? I've been writing AS for a few years now but 
havn't really dived into Classes. I can find a lot of examples from 
digging into code but I'd like to find one that shows step by step 
what it is and why you're doing it.

Thanks
