[flexcoders] Re: WebService bug?
Hi Ben, We are using the 2.0.1 version. I have just discovered that this problem only occurs when using collections of objects that are typed to a superclass of the objects. For instance, I have a class MediaItem. My 2 concrete subclasses are CD and DVD. A CD has a Tracks property and a DVD has a Actors property. When I send over a MediaItem array, it is correctly converted to an ArrayCollection but the Tracks and the Actors collections in the subclasses of MediaItem are ObjectProxy instances. To solve this, let's move the Tracks property of the CD class to the MediaItem superclass. The Tracks property is then also converted to an ArrayCollection. Seems like a bug in the deserialisation of the data, what do you and others think? Should I file a bug and where? regards, Christophe --- In flexcoders@yahoogroups.com, ben.clinkinbeard [EMAIL PROTECTED] wrote: Are you using 2.0.1?

We are sending over nested value objects which sometimes contain nested arrays of objects. When we receive an array in Flex, it is mapped to an ArrayCollection. We then have to do the actual object mapping manually, which is the way to go I suppose. But when we send over nested arrays, the first array is converted to an ArrayCollection successfully but every other (deeper) array is converted to an ObjectProxy in which there is an ArrayCollection that contains the actual data of the Array. There seems to be an extra object/level that gets created. An example (debugger output): result (ObjectProxy) - Components (ArrayCollection) -- [0] (ObjectProxy) -- [1] (ObjectProxy) --- Answers (ObjectProxy, should be ArrayCollection) GapAnswer (ArrayCollection, does not exist in the original object and should not be here) - [0] - [1] As you can see there is an Answers property in the second item of the Components ArrayCollection. This should be an ArrayCollection instead of an ObjectProxy and the GapAnswer property in it should not even exist. (GapAnswer is the type of the .Net Answers array - GapAnswer[] Answers) Has anyone run into this before? Could this be a bug in the deserialization of the objects? regards, Christophe

[flexcoders] ComboBox ItemEditor
I'm using combobox as a dropin item editor in a datagrid. I don't like how many steps it takes to edit a cell... 1: click the cell (renderer turns into editor) 2: click the editor (combobox drops down) 3: click the desired selection (combobox closes) 4: click outside or tab-out to convert the editor back to the renderer and dispatch the itemEditEnd event. When you make a selection in the combobox, I'd prefer it to close up, switch back to the renderer, and then dispatch the itemEditEnd event right away. I've noticed that making a selection in the combobox editor does not dispatch any of the itemEdit events, so I figured I would need to dispatch a combobox change event (from the combobox) and then hopefully use a listener to programmatically destroy the editor and dispatch the itemEditEvent or something. Not sure if this is even possible, but in any case, I can't seem to find anything that can listen to a dispatched event from the editor. I've tried listening for the event on the datagrid, the datagrid column, and the component containing the datagrid... all giving errors. Is this not possible? Or is there a better way to approach this?
[flexcoders] Need primer on Events, from the List Gurus -
Hello All, This thread, directly relates to all the other ones I've posted recently - as I think one of my root problems, is truly understanding on how Events get propagated within an application. They say the Event model is so great, due to all the components being so loosely coupled. So either I am missing something really rudimentary here, or the Event model doesn't work the way I thought it did. In every example I've seen, for an Event Listener and Broadcaster setup to work properly, there must be a common link (like a container) between the 2 components - and then, there are the 3 key things which must be in place: The Event Listener, the Broadcaster, and the Function that gets run whenever the Event gets triggered. But what about the times, where I won't know for sure beforehand, which component I will be using at the time? Especially in a Cairngorm Application, where the Commands (which is where I desperately need to broadcast my Custom Events from) literally NEVER know where their Result Events are going to be sent. Of course, this is where the true power of Cairngorm-based Applications comes into play. All the Commands do really, is update the ModelLocater with their updated results - and because of Data Binding, the Components in the Application show the updated results. For me unfortunately, there is always much more that needs to be done, after a Result is brought back - and I need to find a way to tell my Application Components, to perform their next task (based on a Custom Event, that I broadcast). Can anybody show me how to Broadcast Events in such a manner, that they get disseminated Application-wide??? This way, I don't need to know beforehand, which Components will be Receiving the Events. This is the final thing on my plate that I must figure out, then I can FINALLY finish my app and find some peace in my life Thanks in advance, Mike

RE: [flexcoders] PIVOT CHART (table) .
I've been building some Pivot / OLAP experiments on the side, and gotten pretty far without doing any custom modifications to the default charting components. The result isn't _exactly_ what you're looking for...in my example, each label along the X axis was a multi-line label with each line representing a value from one of the N dimensions (columns) stacked along the X axis. With an added labelFunction, I was able to eliminate the redundant labels and only show them when they're different from the previous label. So it looked something like this: Product: Electronics Clothing ProduceElectronics Clothing Produce Electronics Clothing Produce ... Quarter:Q1 Q2 Q3 ... It's not the prettiest axis in the world, but it get the info across. To do something really well tuned for Pivot/OLAP, you'll need to write a custom axis renderer But that may be all you need to write. Ely. p.s. oo man, not sure I love the name Chartman ;) Charts are really only my night job...

HI All, (Especially hi to Chartman Ely ahem. :)) We have a current project which requires a datagrid to have filter and pivot table capabilities on top of the sort capability. Using that custom datagrid's pivot table functionality will be based on using MS Excel's pivot table. OUr problem however is not on the table but on the chart that is supposedly generated from the pivot table. A pivot chart can have multi-level horizontal labels and tick marks (for those not familiar with pivot table chart, if you have say, a chain of 3 row categories with 3 non-numeric values for each, the x-axis will be divided primarily by the 3 values from the first category - then each of those values will be subvidivided by the number of values the second category have and so on - sort of a fractal/recursive/pyramiding behavior). So with all that said and knowing that we are to use stacked bar chart mean time (although we will probably be required to support the other chart types as well) what is the best way to go about this? Should we play around with the horizontal axis renderer alone? OR should we sublass the whole chart? Or is the data drawing canvas (with custom components inside) the best way to do this?

I'm using a combobox as a drop-in itemeditor in a datagrid. Whenever they make a selection, I don't like how the user has to click outside or tab-out to get the renderer to replace the editor and dispatch the itemEditEnd event. I'd prefer that once they make a selection in the combobox, it closes up, goes away, label renderer reappears with new value, and itemEditEnd event dispatches. I've noticed taht making a selection in the combobox does not dispatch any of the itemEdit events, so I figure I need to dispatch a change event from the combo editor. And then I'm hoping I can have a change listener programatically update the cell, destory the editor, and dispatch the itemEditEnd event. However, I can't find anything that can listen to an event broadcasted from an itemEditor.

[flexcoders] relative paths in the Source paths of Flex Builder
Does anybody know how to create a relative path in the Additional source folders section of Flex Builder? These are for paths outside of the main project path. I would be fine with a way which involves changing the project files directly, which I tried to do. I also tried adding the source paths as source-path parameters in the Additional compiler arguments, but then auto-complete breaks. Without relative paths, I can't create projects files that can be used by a team without changes. It's not that a big deal for me, but a bit annoying. -Brian
Re: [flexcoders] Adding a row at bottom in datagrid with total of all other rows
I just tried to make same thing yesterday.
Collecting values is not a problem, and there is no problem with adding that
row to dataProvider.
Though I ran in huge problems while trying to keep that line on bottom of
dataGrid when user is rearanging data in table.
Code looked something like this:
private function onSorting(event:DataGridEvent):void {
setTimeout(function ():void {
for(var i:uint = 0; idisplayTable.dataProvider.length;
i++){
if(displayTable.dataProvider[i].num == ) {
var totals:Object =
displayTable.dataProvider.removeItemAt(i);
displayTable.dataProvider.addItem(totals);
displayTable.invalidateList();
return;
}
}
}, 10);
}
setTimeout is needed because DataGridEvent.HEADER_RELEASE is broadcasted
before actual rearranging of data.
This code actually never worked as I wanted to. I cought some strange tihngs
during testing like
displayTable.dataProvider.addItemAt(totals, 3);
trace(displayTable.dataProvider.getItemIndex(totals)); wont trace 3, but
last value, so theres maybe a bug in ArrayCollection class, or thats only me
who is doing something wrong.
Anyways, if someone has ideas how to keep one row constantly at bottom, I
preciate that.

Re: [flexcoders] Anyone Using a Remote CF Server with Flex 2, Remoting?
You got it doug. Thats why i copy the services-config.xml file to a local directory in my project and use the -services to tell flex builder how to find it. When I create a new project I tell flex builder its a normal project then I add the -services as a compiler argument. This allows me to develop different applications for different servers without having to manage them all in my main cf services-config file. simeon On 1/11/07, Douglas Knudsen [EMAIL PROTECTED] wrote: no way!

[flexcoders] Re: Filters with DataGrid - Excel
Sanjay,
Did you have any luck converting the DG Header Filter cell renderer to
Flex 2.0? These are the cons that were posted with the code snippet:
CONS
1) you must maintain the same dataProvider.
2) sorting is no good. you might want to re-sort after a filter is
done (but providing events and what not are still something I need to
provide, probable a modelChanged event utilizing the eventName 'filter'
There is still a lot to do for this renderer to make it more usable,
but I figure I've gotten everyone to a dropping off point it shouldn't
be too hard. As I progress with this I'll post more to this thread
#
I'm not sure exactly what you are trying to do. Do you just simply
want a combo-box that you select a field in the list and have it sort
the datagrid? If so I believe you need to use an ArrayList collection
for your dataprovider.
The link that I gave you earlier seems like it would be the best for
filtering a datagrid as you would be able to filter on each
field/column by clicking on the header and selecting an item - which
is exactly what Excel does.
If you were able to convert that datagrid header filter cell renderer
to Flex 2.0 can you please post the source up here?

Re: [flexcoders] Dispatching an Event from a Class
Hey Mike,
If I've understood the previous mails correctly you wish to implement
IEventDispatcher in a class that already derives from another? (i.e. your
ModelLocator).
If this is the case, then in your class that implement IEventDispatcher you
want to create an instance of EventDispatcher, for example:
package com.dts_workshop.flexcoders.eventDispatcher
{
import flash.events.Event;
import flash.events.IEventDispatcher;
import flash.events.EventDispatcher;
public class CustomEventDispatcher extends SomeOtherClass implements
IEventDispatcher
{
private var _dispatcher : EventDispatcher;
public function CustomEventDispatcher() {
_dispatcher = new EventDispatcher(this);
}
public function dispatchEvent(event:Event):Boolean
{
return _dispatcher.dispatchEvent(event);
}
// Rest of implementation
}
EventDispatcher allows you to create an instance of it, passing in the class
that implements IEventDispatcher but cannot derive from EventDispatcher. Any
events raised will have the correct target.
For more information, take a look at the info for EventDispatcher in the
Flex 2 help.
Regards,
Oliver Tupman.
I hope that's what you're after.

They say the Event model is so great, due to all the components being so loosely coupled. So either I am missing something really rudimentary here, or the Event model doesn't work the way I thought it did. In every example I've seen, for an Event Listener and Broadcaster setup to work properly, there must be a common link (like a container) between the 2 components - and then, there are the 3 key things which must be in place: The Event Listener, the Broadcaster, and the Function that gets run whenever the Event gets triggered. But what about the times, where I won't know for sure beforehand, which component I will be using at the time? Especially in a Cairngorm Application, where the Commands (which is where I desperately need to broadcast my Custom Events from) literally NEVER know where their Result Events are going to be sent. Of course, this is where the true power of Cairngorm-based Applications comes into play. All the Commands do really, is update the ModelLocater with their updated results - and because of Data Binding, the Components in the Application show the updated results. For me unfortunately, there is always much more that needs to be done, after a Result is brought back - and I need to find a way to tell my Application Components, to perform their next task (based on a Custom Event, that I broadcast). Can anybody show me how to Broadcast Events in such a manner, that they get disseminated Application-wide??? This way, I don't need to know beforehand, which Components will be Receiving the Events. This is the final thing on my plate that I must figure out, then I can FINALLY finish my app and find some peace in my life Thanks in advance, Mike -- WARNING --- This electronic message and its attachments may contain confidential, proprietary or legally privileged information, which is solely for the use of the intended recipient.

[flexcoders] Cairngorm 2.1 temporary 'stuff'
Hi all, I've just finished re-coding an application so that it uses Cairngorm 2.1, and was wondering what other people did in a few situations that I came across. In Cairngorm the general idea is for the view to be bound to the model, or for some code that watches for changes to the model and then updates the view. The commands update the model, the stuff watching the model updates the view. That's great, but what does everyone do for transitory parts of their workflow, for something that comes and goes quite quickly? For example, I have an initialisation routine that needs to set various bits and pieces up in the application. I display a small window to the user informing them of this process (I don't want to use the preloader). To me, the Cairngorm methodology says to put some sort of initialisation status data in the model, perhaps an array of tasks that need to be completed before the application is ready to roll. My initialisation window should then watch these items in the model. To me it seems a tad wrong to put data that is required on a one-off basis into the model, though I can't quite put my finger on what's bad about it. Perhaps the fear that the model will become a dumping ground for every piece of data, regardless of the lifetime of that data. Has anyone got another way of doing this sort of thing or any thoughts on the matter? Another similar area that I'm curious about is the subject of presenting alerts to the user. A simple example is warning the user about deleting something on the server that will result in other items being deleted too. Let's say that the user decides to delete something from within the Flex app, the app queries the server asking whether it's possible OK to delete it, the server says not quite and so the app must ask the user what to do. I think that a command in there is going to have to present the user with an message of some description. I'd rather not tie a command to the Alert class because I may want to use some sort of custom class to display the message at a later date. Anyone any ideas on that? The thought that pops into my head is to have some sort of factory class that the command accesses to get some sort of alerter, one of which could wrap/extend Alert, another could be a custom alerter class. Or perhaps it would be better to make use of the ViewLocator? Cheers, Oliver Tupman.

[flexcoders] datagrid row moves up to the header when scrolled?
Hi All, I am facing lot of problem with datagrid. In my datagrid i have area chart in each cell. When i scroll the datagrid down, then first row moves upto the header instead of disappearing and extra comes from down, so if you have rowcount as 3 you will see 4 rows with one row on the header. Is this a performance issue or a flex bug ? Have a burning question? Go to www.Answers.yahoo.com and get answers from real people who know.
[flexcoders] Getting height of dynamically-adjusted component?
Here is what I am attempting to do: I have a series of canvases that have a specified width. Each canvas also has a different text string in it. The height of the canvas will change based on the length of the text string. I would like to place these in an HBox and have their heights equal to the tallest canvas. All of this is being done programatically. When I try something like: (hbox.getChildAt(0) as Canvas).height I always get a return of 0. I know the height can't be zero, but there it is. I would like to know the height, because I could then loop and set the height of each canvas to the tallest. An example I am working off of can be found here: http://pastebin.com/857934 I appreciate any and all feedback!
[flexcoders] MDI, Cairngorm TitleWindow
Context: I am trying to simulate a MDI application with TitleWindow containers (poor's man MDI :P ) loading diferent forms compiled into modules (flex 2.0.1)...

[flexcoders] Patterns for managing large collections of data model objects in ActionScript
Greetings,
I've been working the past few months on building a fairly complex
application using a Rails back-end and Flex front-end. It's just about
ready for release to our client, but I'm having trouble with one area
of the applications.
The application itself is a workflow tracking/automation and
softproofing application. The main sturcture of the app is such that
(at a high-level view) a user can select a set of filters based on
production data, apply those filter to get a result set that
consisting of View objects that are displayed in a datagrid, drag
certain Views from the result set into a lightbox, and then open one
of those Views in the softproofing screen.
The result set data grid, lightbox and softproofing screen all use
seperate data providers, so that -- for instance -- you can place a
View in the lightbox and then apply a different set of filters while
still keeping that view in the lightbox.
I'm using REST webservices to communicate between the Flex client and
the server (Ruby on Rails), and all results are returned in XML. When
a model object (on the Flex side) is hydrated from the XML, I place it
in a master collection that is independent of any display object's
data provider. When the object is placed in a display object's data
provider, it is referencing the object from this master collection.
This is to ensure that if the data for the object is updated by either
an action within the client or an update form the server, it is
updated everywhere that it is displayed.
I'm using (perhaps abusing, even ;-) ) Cairngorm for this project. The
master collections are stored as ArrayCollections on the
ModelLocator instance, and the model classes themselves refer to these
collections to keep track of the instances. So my ModelLocator might
be defined as:
## BEGIN Locator.as ##
[Bindable]
public class Locator implements ModelLocator
{
private static var modelLocator:Locator;
public static function getInstance():Locator {
if (modelLocator == null) {
modelLocator = new Locator();
}
return modelLocator;
}
public function Locator() {
if (modelLocator != null) {
throw new Error('Only one Locator should be instantiated!');
}
modelLocator = this;
}
public var views:ArrayCollection = new ArrayCollection();
public var filteredViews:ArrayCollection = new ArrayCollection();
}
## END Locator.as ##
and the View class defined as:
## BEGIN View.as ##
[Bindable]
public class View
{
public var id:Number;
public var code:String;
// more attributes defined as needed
private static var model:Locator = Locator.getInstance();
public function View(data:XML = null) {
if (data) {
update(data);
}
}
public function update(data:XML):void {
this.id = Number(data.id);
this.code = data.code
// more attributes pulled from XML data s needed
}
public static function find(id:Number):View {
var cursor:IViewCursor = model.views.createCursor();
var view:View;
while (!cursor.afterLast) {
var item:View = View(cursor.current);
if (item.id == id) {
view = item;
break;
}
cursor.moveNext();
}
return view;
}
public static function addOrUpdate(data:XML):View {
var view:View = find(Number(data.id));
if (view) {
view.update(data);
} else {
view = new View(data);
model.views.addItem(view);
}
return view;
}
}
## END View.as ##
When a user applies a filter set to query for a set of views, the
following occurs:
1. a FiltersEvent is dispatched with type APPLY
2. the FrontController associates this event with an ApplyFiltersCommand
instance and calls the execute method on it.
3. the execute method call a ViewDelegate to invoke the service
asynchronously.
4. the service returns an XML dataset and the result method is called
on the
ApplyFiltersCommand instance
The result method is defined as:
## BEGIN ApplyFiltersCommand.as result method ##
public class ApplyFiltersCommand implements Command, IResponder
{
private var model:Locator = Locator.getInstance();
// execute and fault methods excluded for brevity
public function result(data:Object):void
{
var result:XMLListCollection = new
XMLListCollection(XML(data.result).children());
var cursor:IViewCursor = result.createCursor();
var views:Array = new Array();
while (!cursor.afterLast) {
views.push(View.addOrUpdate(XML(cursor.current)));
cursor.moveNext();
}
model.filteredViews.source = views;
}
}
## END ApplyFiltersCommand.as result method ##
The result method sets up the data provider for the results data grid
as an ArrayCollection containing View objects. Rather than just
creating new View objects, it uses the View.addOrUpdate method to make
sure that, if a View object with the same id attribute is being used
elsewhere (in the lightbox, for instance), it's properties are updated
with whatever the server returns.
This approach works

RE: [flexcoders] Export FLEX page to PDF
It is possible, I searched a while back for a similar solution and found some .NET components that would do it (not from Flex/Flash, but from data inputs - you would send your app data to a script like c# which would send the required data to the .NET component which would spit out the PDF). You should be able to find some solutions with some Googling.

[flexcoders] Re: Should I be using States to switch between views?
I have found that using states is the best solution for me. Remember you can add OR remove items from your view and if you are using components, just by removing 1 or 2 of them, the view can drastically change. Also, states lets you base a state on a previous one so there is very little code required: Also, since you can have a function called when the state has been instantiated, I have found that a great place to call any startup function (which can be a problem since everything in flex is Async.

[flexcoders] Modules Example and Tutorial
Peter Ent has posted an excellent example of how to use modules, including how to communicate with modules and handle module events. See: http://weblogs.macromedia.com/pent/archives/2007/01/building_module.cfm His example and explanations answer many of the questions I've seen lately about Modules. He includes a complete code download.

Re: [flexcoders] Export FLEX page to PDF

[flexcoders] Dispatch and Listen for events?
Hi,
I am not using Cairngorm or anything yet, but trying to learn to build
some of this on my own through tutorials, books, etc.
I am trying to build a basic login and I created a custom component
called LoginPanel.mxml, and created a LoginEvent.as. I call
LoginPanel.mxml in my Main application file by doing:
comps:LoginPanel / My goal is to let the user click the login button,
create a loginEvent then dispatch the event, finally have some event
listener on the other end receive notification then make a call to my
Remote Object in my Services.mxml file. I think once I get to the
remote Object call I can fiddle my way from there.
I am confused on how and where to tie my event listener in and once
the listener receives notification, the code that follows.
I have a private function in LoginPanel.mxml (my login form) called
doLogin(). Code is shown below:
private function doLogin():void {
var loginEvent:LoginEvent = new
LoginEvent(username.text, password.text);
this.dispatchEvent(loginEvent);
}
}
My LoginEvent.as code is here:
package com.adobe.events {
import flash.events.Event;
import flash.events.EventDispatcher;
public class LoginEvent extends Event{
public var username : String;
public var password : String;
// constructor function
public function LoginEvent( username:String, password:String ) {
this.username = username;
this.password = password;
}
}
}
Is this correct?
Thanks in advance for any assistance...
[flexcoders] Webservices request serialization issues.
Hi, I am using Flex 2.0.1 based application to communicate with web services written in Java (JAXWS). System should send requests using complex objects with nested structure and it does it ok. The problem appears when I have inheritance in the object graph. I have base class X , two derived classes, Y and Z, and two more YA and ZA. x - y - ya x - z - za X contains common fields such as ID and NAME. Object that I send contains reference to the base class X, but the instance of the objects is YA or ZA. When the request is being sent, I can see only the common properties taken from X, and none of the impl specific fields, although wsdl/schema defines those. When I change the reference type to Y or Z I get the same behavior, so the only way is to define reference to YA and ZA directly, which is not a nice way to go. Now the funny part that the situation is being solved if I move the common fields from x to y and z (duplicate the fields), and leave the X class empty !!! But this approach stops working if I use array of objects, and not only one. Can anyone shed some light of the serialization logic in case of inheritance? One more thing, what is the way Flex deals with inheritance when reference is not the final impl, but to the base class ??? Other WS entities would use techniques such as xsi:type definitions in the dispatched XML ... For now I am solving it by adding field to each derived class, with the actual class name, catch it on the server side, and add xsi:type manually, but this way is not the one I would like to stick with Thanks in advance.

getting the expected result.
I've got some simple code where i wish to execute a function when a

== null
2. The callbackHandler is not getting called when the value does get
set.

RE: [flexcoders] Need primer on Events, from the List Gurus -
Hello Dimitrios, I was trying to keep my post as generic as possible - which is why I didn't post specifics. In this particular instance however, I want to broadcast a Custom Event to a DataGrid residing on a Panel Control - to Scroll to the very top, whenever I add a new record to an ArrayCollection (residing in the ModelLocater). This can happen ONLY when I add a new record - and this is why I want to create a Custom Event for this. I am pushing for a Custom Event, because I don't think there is a built-in Event native to the DataGrid, that I can count on 100% of the time, to fire off ONLY when New Records are being added. The catch is, I can't dispatch the Event until I get my onResult response from the ColdFusion Server - indicating that the Database Insert was in fact successful, and that it's now okay to update the Model's ArrayCollection with the new ValueObject. Since the onResult logic resides in a Cairngorm Command Class, this is where I need to dispatch the Event from. Or at least initiate the command to dispatch the Event, which can reside in the ModelLocater - and dispatch it from there. Since all of my primary Views containing the Model-bound Controls, have a reference to the ModelLocater, I am thinking that there must be a way to dispatch these Events from the Model - and have a way for these Views to respond accordingly. If you could help me out in this regard, I really would be truly grateful. My application development, has literally come to a screeching HALT, because of me not knowing how to handle all these issues. I am tracking down every Event Broadcaster and Listener Tutorial I can get my hands on, so that I can learn more about how all this works. But in all of the examples I download and dissect, they ALL have a common View, that centralizes the code - in which it's quite easy to tie everything together. In my case, I have Views and Controls scattered all over the place - and they can be instantiated (or not be for that matter) at any given moment. I just don't know how to write code to broadcast Events in such a manner, so that each component has no prior knowledge of any other component. I hope I'm explaining all this properly...

Re: [flexcoders] Need primer on Events, from the List Gurus -
Maybe the following will help.
Data Binding is really just a short hand version of an event broadcast, and
listener and function to be executed.
Take the example:
[Bindable]
private var lastname:String;
mx:Text text={lastname}/
mx:Button click=lastname='My last Name'/
--
When the button is click the variable lastname value is updated to 'my last
name'.
Since lastname is Bindable, it dispatches an event (broadcaster) that the value
has changed. Any control listening to the change event, receives the event and
runs a function to updates the property text to the new value. This of course,
invalidates the display which then the display gets updated.
The Bindable metatag creates a dispatch change event (Broadcaster)
The {lastname} creates a listener for the text control to listen to the
lastname change event
A function is created that updates the property, text in this case, to the new
value of last name.
I am sure it is more complicated than this (A function can also be Bindable,
how does the function know when it changes value?).
You can implement data binding using the event model. It might be a good
exercise, but you would not want to do it this way in an application.
I know the above helped me greatly in understanding the events model. I hope it
helps.
To answer your question
But what about the times, where I won't know for sure beforehand, which
component I will be using at the time?
Using the above data binding example, data binding has no knowledge of what
component will be using data binding. Data binding can be used on just about
any component property. Again, data binding is a short hand of an event model
and each component doesn't care what component will be used.
The event model loosely couples the components, but both components must know
about the event model. Any component that creates an event listener and the
function that should be executed when that event is triggered. The component
must know about the event structure. The component that dispatches the event
must also know the event structure. The event becomes an API, so to speak. Any
component can listen or dispatch to that api. In other words, the event itself
is communication between the two components and both components must know how
to speak and listen to the event.

RE: [flexcoders] Need primer on Events, from the List Gurus -
With what you said, it pretty much backs up what I already knew to be
true.
When it comes to the basics, I am pretty well-versed with Data Binding -
and of course, writing some pretty extensive Cairngorm-based RIA, I have
a pretty good handle on the flow of things.
I guess what is making me second guess what I know about Events, is the
fact that I can't get this damn thing to work. I am scratching my head
on this, and can't figure out what I am missing.
Take this simple example:
Main Application
View1
View2
In View1, I have a basic Panel with a DataGrid. I have a Bindable
public var (myArrayCollection), and assigned it as the dataSource for my
Grid. In my AS Code, I created a var referencing my ModelLocater. Then
I set local myArrayCollection var equal to model.myArrayCollection.
This takes care of all the var declarations, as well as properly
dataBinding it to the Model.
Everything is great - data updates perfect, yada yada yada...
Now I want to add 1 more piece of functionality - broadcast an event, to
make my Grid scroll to the top, after a new record is added. Sounds
easy enough...
Here is what I added to make this happen:
1) Added an eventListener to View1, that listens for scrollGrid -
which gets attached to the appropriate function (scrolling the Grid to
the very top).
2) Added extra logic to my Cairngorm getDataCommand Command - which I
put in the onResult Event Function. The code to call the function
(because the function resides in my ModelLocater) is
model.fireOffScrollEvent. The function simply dispatches a generic
Event (with the Event String being scrollGrid).
Now here is where I get confused:
Other than the simple variable reference in View1 to ModelLocater, there
is nothing else tying these 2 Classes together. I say Classes, because
Controls in essence are simply Classes, in addition to the fact that
ModelLocater really doesn't extend anything.
So now, when I dispatch the scrollGrid Event from inside of
ModelLocater, nothing happens on View1. See, this is where my
understanding of Events, falls terribly short.
See, in the times like this, I am not sure how the Application
propagates these Events. When an Event gets dispatched, does Flex
systematically broadcast it to each and every component??
What confuses me too, is all the scoping stuff - which was a really big
deal in Flash. In Flex, you don't use any dot-notation to specify
where the Event should go (like
Application.application.View1.myDataGrid) - it just goes somewhere out
there - like a black hole some place. When they mention bubbling, I
thought this meant just that -
Since this isn't working for me, I am obviously doing something wrong.
So the question is, what extra code must I add, to make the ModelLocater
aware of View1 and vice versa?
Thanks in advance for your time on this -
Mike

Maybe the following will help.
Data Binding is really just a short hand version of an event broadcast,
and listener and function to be executed.
Take the example:
[Bindable]
private var lastname:String;
mx:Text text={lastname}/
mx:Button click=lastname='My last Name'/
--
When the button is click the variable lastname value is updated to 'my
last name'.
Since lastname is Bindable, it dispatches an event (broadcaster) that
the value has changed. Any control listening to the change event,
receives the event and runs a function to updates the property text to
the new value. This of course, invalidates the display which then the
display gets updated.
The Bindable metatag creates a dispatch change event (Broadcaster)
The {lastname} creates a listener for the text control to listen to the
lastname change event
A function is created that updates the property, text in this case, to
the new value of last name.
I am sure it is more complicated than this (A function can also be
Bindable, how does the function know when it changes value?).
You can implement data binding using the event model. It might be a
good exercise, but you would not want to do it this way in an
application.
I know the above helped me greatly in understanding the events model. I
hope it helps.
To answer your question
But what about the times, where I won't know for sure beforehand, which
component I will be using at the time?
Using the above data binding example, data binding has no knowledge of
what component will be using data binding. Data binding can be used on
just about any component property. Again, data binding is a short hand
of an event model and each component doesn't care what component will be
used.
The event model loosely couples the components, but both components must
know about the event model. Any component that creates an event
listener and the function that should
