RE: [flexcoders] modelChanged event
I think it stems from the use of an array in databinding. One way to fix this is to reassign your dataprovider. Also you could broadcast a model change event upon completion of the changes. This would hopefully then trigger the sum to change.

[flexcoders] Confusion with mx:Repeater
I get the basic concepts of Repeaters and have successfully gotten one to
show me one via a dataprovider. I am now having a bit of trouble
understanding how to manipulate items in the Repeater. I know that I have
to be careful with data in Arrays because they will not fire ChangeEvents
but that doesn't seem to be a problem so far.
Below is a test screen that I wrote. If I remove the last item first, and
then the remaining item it works. If I remove the first item and then try
to remove the remaining item, the remaining item is not removed. I am sure
this is probably a limited understanding of the calls and use of the
Repeater but the documentation seems a bit sketchy on them beyond just for
display.

Ok. Now I get it. Thanks Steven, Allen, and Alex. I was missing the
binding that Alex pointed out and was not entirely clear on the data binding
which is coming into focus. (looking at individual entries in the book and
missed the chapter headings bashful grin). So what ends up happening is
that we can avoid firing a change event and that overhead by putting the
shopping cart into an object. As the object changes it causes the
dataProvider binding to be updated automagically. Very slick. I guess I
need to read chapters 15 - 18 closely and play with them. Some of this
stuff is great on paper but doesn't sink in until you are actually trying to
do this sort of manipulation.

Hi Kent,
we decided to make 5 components of Cairngormstore more modular and
abstracted the ModelLocator. The ShoppingCart.mxml component was one of
those components. If you look into Main.mxml you'll see the inisialisation
of ShoppingCart.mxml
cart:ShoppingCart id=shoppingCartComp width=100% height=100%
shoppingCart={ModelLocator.shoppingCart}
selectedItem={ModelLocator.selectedItem}
select=ModelLocator.selectedItem = event.target.selectedItem
currencyFormatter={ModelLocator.currencyFormatter} /
ShoppingCart.mxml accepts a shoppingCart instance of type
org.nevis.cairngorm.samples.store.business.ShoppingCart. In our case this
comes from ModelLocator. The dataProvider property of the DataGrid in
ShoppingCart.mxml is bound to the elements property of
org.nevis.cairngorm.samples.store.business.ShoppingCart. This ShoppingCart
class is also in the as2docs. Basically, the elements property is a
collection of ShoppingCartElement objects that represent one element. The
ShoppingCart class itself represents all elements and some additional
connected information concerning all elements like the totalProductPrice or
shippingCost.
hope that helps,
Alex

RE: [flexcoders] Modifying Panel and Text Input
Ok. Now I feel a bit sheepish. It states in the Action Script Docs for FormItem that 'required' property just shows or hides the asterix(star) in the UI. Nothing more. I got myself totally confused by looking at the Flex Store example that sneaks in their own validator, RequiredFieldValidator. I assumed that this was part of either the StringValidator, if you applied it to a field, or it was tied into the 'required' field. Could somebody at Macromedia please make a simple addition of a required field to the StringValidator or just make it so that if you apply it to a field it becomes a required field. This would be similar to how the EmailValidator behaves. (you input a character, remove the character, the move to another field, the email field will be marked as required.)

mx:title{ModelLocator.title}/mx:title
/mx:Panel
I did find something that looks like a problem, the icon property of Container

it would put the icon next to the title. Maybe there is another way to put an

RE: [flexcoders] Flash + Cairngorm Example With Source Code
Thanks Robin and Steven. That makes total sense. I have been approaching my current implementation with a background in Java and JSPs not in Cold Fusion or even thinking about it by doing what I would call a poor mans version of web services (xml sans SOAP). I have been lucky enough to be using the AMF gateway for this. In the end I am left with the following network architecture: Flex Side Network J2EE Server - -- || - --- -- | Command | = | Delegate | = || = | Command | = | Business Delegate | = | EJBs | - -- || - --- -- By doing this I allow Struts to be a Command on the server side and can keep my Business Delegate clean of any HTTPRequest or AMF processing knowledge. I guess the only open question is would you still pass different Command objects to the Delegate on the Flex side and have more then one function in the delegate that does processing or would you keep it as a one to one relationship between Commands and Delegates to avoid accidental calls of the wrong onResult handler? BTW Once I finally got a grasp on the basics of Cairngorm and Flex my development has been able to movie very fast.

Another similar example is a Flex application we're working on that communicates in xml request/response strings with the server. All the creation of the xml request string and the parsing of the response are handled in the delegates - if we swap to a non-xml format later then the Commands will be none the wiser, they work exclusively with VOs. Finally, in the same application we have a few commands that trigger off a string of four or more server calls via delegates in a row, so the mapping of commands to delegates is 1:many (I've written a little state-machine logic in my commands onResult using (gasp) a case statement - unfortunately I haven't seen Steven's solution for this in 0.99 at this point, will have a look soon but it may take a bit to tear me from my state machines, which work rather nicely). smime.p7s Description: S/MIME cryptographic signature

[flexcoders] Cairngorm, why use delegates?
Now that I have a pretty good understanding of Cairngorm and its structure I want to put out a question about why to build commands and delegates in the way presented in the store example. The Command/Responder object always talks to a single delegate object. This delegate object uses the Services.mxml file to determine where to go on the server side. Because of the structure of the delegate you have to be very careful if you want to pass it different command objects to be responders so that you don't have inappropriate behavior in the UI. You could always do a one to one relationship between commands and delegates but you end up with an explosion of different objects. Why not simply bind in what the delegate is currently doing into the command object and have a duplicate command POJO on the server? This way you could have special handling for Flex calls on the server that pull items from the HTTPSession, if needed, and then call a delegate that has multiple methods on it. This way you isolate the Flex pieces from your delegates and can always put another framework like Struts on top of your delegates to provide another user interface. Struts Actions are effectively the Command pattern with a different name. Maybe it is a future expansion point that I am not thinking about.

It is more of a document-scope issue. Each MXML file is its own

document with one radio button in the group.
You might have better luck using an ASComponent subclass of
RadioButton as the cellRenderer. Create a .as file that looks sort

In a Struts/JSP application you can put severlet filters in as a way to cross cut your system and provide validation of login/session on a user. If it fails, you redirect the user to a login page.

If so what will be sent back to the Flex Client that I can grab so that the user will get redirected to a login (and eventually resend their data if valid)?

Hi, Stephen, et al
I have implemented your business delegate scenario as outlined in the
book in chapter 20. It works very well, except for when java throws an
exception, the onFault never catches it. In network Monitor, I can see
that an onStatus, probably System.onStatus, is invoked. I coded my
delegate classe exactly as you have on page 479, and the onResult
works fine. Can you give me any pointers to make the onFault catch
the exception so I can handle it?
Thanks,

RE: [flexcoders] Re: Application flow best practices?
Thanks Andrew and r0main. That was a perfect description of what I needed.
Now to do a bit of thinking in the flow aspect to get a feel for that
method. Andrew, you described the exact problem I am trying to solve. I
have a view stack for the Login versus main application, and then was
thinking of doing a view stack for each of the screens within the flow. I
still have not been able to determine how I might be able to use the
TitleWindow correctly in my own application.
Thanks for the description of the view data member in Cairngorm .99 This
should probably be added to the AS Docs on ViewHelper so that people know
what it references in their sub classes as they go through the store or
login example. Maybe that description is coming with the eagerly awaited
PDF on the framework and store.(Happy to help edit and comment on that doc
if somebody form iterationtwo wants to send it my way)
Regars,
-Kent

I do agree with Andrew on the view helpers states in a ModelLocator
and using bindings.
Just remember you can have many ModelLocators in an application, so
one may be dedicated at holding application-states, and another one
may be the classic one, which holds your data.

Hi Kent,
If you are using Cairngorm 0.99 there is no need to set the view like
this:
view:IndexViewHelper name=indexView view={this} /
The above syntax is no longer necessary, and has been replaced by a
much simpler use of the id attribute, making it simpler to call a
function on the viewHelper within that view.
view:IndexViewHelper id=indexView /
Regarding the view data member, it is a part of the ViewHelper which
extends MXMLObject. It has an initialized method which is called by
the Flex component framework after a component has been initialized.
This method takes 2 parameters, first being the parent document (the
view object) and the second is the id of the view helper. In here the
view attribute is set.
To provide an idea of how I manage multiple screen views is that I
have multiple workFlowState attributes in the ModelLocator, which my
view stacks are bound to. For instance I have an
applicationWorkflowState which switches views between the login screen
and the main application (being another view stack). And then for each
sub application (or section) I maintain a separate workflow state.
Hope this makes sense. But I'd be interested to hear how others
approach this issue.
Best,
Andrew Spaulding

Kent,
The view member variable is passed in from the calling MXML file
as a
parameter of the tag. In the case of IndexViewHelper you might call
it as
as:IndexViewHelper name=indexView view={ this } /
assuming your name space for that tag is 'as'.

RE: [flexcoders] Panel hearder-colors restriction or bug
Thanks Manish. I can safely say that there are two bugs. One in the StyleExplorer, which makes some sense, and one in FlexBuilder itself.

[flexcoders] Panel hearder-colors restriction or bug
I started playing with the Style Explorer (very cool!!!) and was trying to
mess with the head-colors and making a nice gradient. I tried some hex colors
and it came out wrong. So I made a quick example in FlexBuilder only to find
that Flex/Flash is not behaving how I would expect it.
If I specify a single color for the header I get that color no matter the
value. If I specify a second color, for the gradient I assume, I get black.
See example code below.
I know that I am not using colors from the color picker in the Style Explorer
so I am guessing there is some restriction on the colors I can choose. Can
somebody confirm or deny this? If there are restrictions what are they?
Thanks,

RE: [flexcoders] Remoting Examples for Flex?
Checkout the FlexExplorer samples. http://localhost:8700/samples/explorer/explorer.mxml with the integrated JRun server. If you look under Dynamic Data Services you will see how to do RemoteObject and Web Services. You will probably want to look at the Java files on the server side also.

Hello All, I just joined this list recently -as I came over from the FlashCoders list. I am sure most of you on this list, are also from FlashCoders, since Flex isso closely related to Flash. I've been searching the Docs best I can - and I haven't found any examples or instructions on how to perform Remoting Calls from inside of Flex. I've found the RemoteObject mentioned - but am not entirely sure how touse this. I have this down to a science in MX2004 using all the Remoting AS files, etc. but I've done very little with Remoting using Components. I am a coding guy - so this is all a little awkward, going back into a Drag and Drop environment - and setting all my parameters using a Property Inspectors, etc. Well, if any of you could point me in the right direction, I'd greatly appreciate it.

[flexcoders] Session Access in Delegates
I have been digging around in the remoting example code to try to figure out ways to handle the system I am working with that stuff certain attributes into the session upon login rather then retrieving each time. The first question I have is Where can I find the JavaDocs for flashgateway and calls like flashgateway.Gateway.getHttpRequest()? Second I am looking at the example login that comes with Cairngorm and wondering what the scope of the CustomerDelegate object is. I would think that the object should have nothing but static calls but It acts as an instantiated object. Maybe it is just a mater of reading up on Flash Remoting. If so just point me in the right direction. TIA, -Kent smime.p7s Description: S/MIME cryptographic signature
[flexcoders] Internationalization?
I did some digging through prior posts to see if there were some comments on internationalization best practices but haven't found much.

How are others currently solving the problem of internationalizing their Flex applications? Has there been any commentary from MM on when they will roll this into Flex?
