[flexcoders] Re: One custom component referring to another
Jason,
In an ideal world, component A would throw events up. Those events
would be caught in the application (in this case) and call
corresponding methods in component B.
You really, really don't want to start coupling these components
together by calling the internals of one from the other in this way.
Especially when they really are peers in your application.
Just my 2 cents,
Mike

How do you handle this? I know this probably isn't ideal
architecture, but would there have to be scripts that listen for
events in one component in the main app and then modify the other
component? I guess I could do that if it is best practice. I need
the two components to be separated because they are two different
parts of the UI, but need to interact. One has controls that change
the view and data in the other. Does it have to modify the other
component from actionscript on the main app or can I just pass a
reference into one component like I have tried?
Thanks.

[flexcoders] Re: New to flex, wonder why one works and the other doesn't...
Close, but no. In Flex, parents are responsible for sizing their children. Flex Containers (which are just UIComponents with more code) do size their children, but you can also create UIComponents that know how to size their children. Neither a container, nor a component that implements a container interface needs to be involved in any way to handle this. That is the fallacy I am addressing. Look at the example I provided and you will not see a Container or implementor of that interface. In other words: * UIComponents can contain other UIComponents. * Containers are UIComponents which know how to automatically size their children through the component lifecycle Does this make sense? Mike --- In flexcoders@yahoogroups.com, Joseph Balderson [EMAIL PROTECTED] wrote: In other words, UIComponents /can/ natively contain other UIComponents, only the child UIComponent will by default have a 0 width and height. Which it means it won't show up on the stage. Which means, by default, you cannot get a native (non-extended) UIComponent to show up when you add it to another UIComponent. Which means you cannot (successfully) add a native UIComponent to another UIComponent. Thanks for catching the technicality, as a writer I love that kind of precision. But basically what Charlie was saying is correct: UIComponent's can't contain other UIComponents without being a subclass of Container or implementing the IContainer interface. -- only he forgot to add 'and have them successfully show up on stage'.

As per my knowledge after completion of teardown() of testcase1
then it
should go for 2nd test setup() and this works fine. But what is

that UIComponent maintains list of function to be called.
UIComponent is not calling individual functions. So login is called
perfectly but logout is not being called. So 1st testcase it is
working but
for 2nd testcase it's giving error. This error is due to logout

[flexcoders] Re: Defining a dynamic UI
To add to what Tracy was saying.. Let's say you have a component in the comps directory called MyComp. It could be in MXML or in Actionscript, it doesn't matter. First you would need to import that component definition by saying import comps.MyComp; Then, at anytime, for instance in response to a button click, you can say: var someVar:MyComp = new MyComp(); someVar.property1 = 3; someVar.property2 = 7; this.addChild( someVar ); or myViewStack.addChild( someVar ); You could make a series of functions which create these components and set them, calling the appropriate function when needed. Or you could dig a little further and learn about factories... is this basically what you were trying to do or are we missing your point?

I don't know if the mx:Component tag can be used anywhere other than in an item renderer(state?), but you might check. And you can instantiate controls at will using container.addChild().

I will decide whether or not to add them based on runtime criteria. I know that I can use states to add and remove components. If I use states, is there a way to define a component only once in MXML and then add it in 3-4 different states? I do not wish to define my component over and over inside of AddChild tags, and my components are not really specialized enough to warrant their own MXML files since there are many of them and the only real differences are their properties, events, etc. I've also thought that I could manually define my components in AS and keep them in memory until needed, but would rather define them in MXML if possible. I would also like to create the components just-in'time instead of creating them up front when they may never be needed. Anyway, thanks for any thoughts on this topic!

Hi all,
I'm trying to install fds as service on Win2003.. i've read that it was
possible with jrunsvc but it doesn't work with the following command
line :
jrunsvc.exe -install jrun-server Flex data service Flex Data Service
(I find the jrunsvc from Coldfusion installation directory)
Is it something wrong ?

[flexcoders] Re: Tree not updating with correct XML
Aaron,
Need to clarify something:
When you say : The XML is changes, do you mean that the XML data
retrieved from http://Path/To/XML.aspx changes or that you change the
XMl after loading at the client?
I don't want to answer the wrong question, but the
mx:XML tag includes data at compile time, not runtime. So, the
application is going to grab a copy of this data when it compiles and
build it in.
If you are looking to grab data at runtime, you need to look at
something like an HTTP service tag to go and grab the data on command.
Let me know if this answers your question,

Hi all,
I'm at a loss here. I've got a tree set up to retrieve XML data.
It works fine until the data in the XML changes. Then the tree
won't reflect the new data until my flex application is recompiled.
I believe when the application is being recomplied it's grabbing the
XML and setting it somehow. Here is some code.
CODE***
mx:Script
![CDATA[
import mx.events.ListEvent;
import mx.controls.Alert;
import mx.collections.*;
[Bindable]
public var myXLC:XMLListCollection;
public function afterComp():void
{
myXLC = new XMLListCollection(TreeXML.children());
tvwProjects.invalidateList();
}
]]
/mx:Script
mx:XML source=http://Path/To/XML.aspx; id=TreeXML/
mx:Tree id=tvwProjects width=100% height=100%
dataProvider={myXLC} labelField=@label itemClick=treeClickEvent
(event); y=10
/mx:Tree
END OF CODE***
I've also tried the above without the XMLListCollection and just
putting the TreeXML straight into the Tree object dataProvider. The
afterComp function is called in the application createCompletion
event. I've also tried with and without invalidateList.
Basically, How can I get the Tree control to grab the latest and
greatest from the XML?
Thanks,
Aaron

[flexcoders] Re: using a linkbar with a viewstack... how can you indicate current selection
Hank, If you are setting the dataProvider of the linkBar to the viewStack, the LinkBar will indicate the selectedChild of the viewStack as a disabled button on the bar. The linkbar responds to the viewStack. When you say you are setting the selectedIndex to 0, do you mean you are setting it on the viewStack and the linkbar is not responding? As far as the styles, the linkbar has a fair amount of style customization all defined in the LinkBar help docs.

I know I could use a tabBar, but I like the simple blocks of text without the tabby look and feel.

As an aside, please take a look at the refresh method of the

[flexcoders] Re: Custom datagridcolumns
Rick,
Just one more comment on your labelFunction versus subclass of
DataGridColumn. There are times to subclass, but, what you are doing
here really seems like a good argument for a labelFunction.
You don't have to build a function for every column, so, if you
rewrote your labelFunction like this:
mx:CurrencyFormatter id=currency precision=2 rounding=nearest/
mx:DataGridColumn width=80 headerText=Legal Credit
labelFunction=formatLegalCredit dataField=LEGCRAMT/
public function formatLegalCredit(data:Object, column:DataGridColumn
):String {
return currency.format(data[ column.dataField ]);
}
You would now have one function that would format any dataGrid column
because it uses the dataField to know where to grab the data. Does
this make sense?

currency.rounding = nearest;

Can I build a datagridcolumn that automatically has a

[flexcoders] Re: Training from the Source - Can't find my error
Glad you are enjoying it.
We have occasionally seen the same thing. The flex compiler seems to
get confused with the inline renderer and the valueObject.
This line is the cause:
outerDocument.removeItem(valueObjects.ShoppingCartItem(data));
You can literally go an modify this line by adding a space before the
word valueObject. Then remove the space and all will work next time
your compile.
It doesn't happen everytime on every computer. If it becomes
problematic, just remove the entire click event from the delete in the
shopping cart. My guess is that by this point in the book, you
understand how that is supposed to work.

[flexcoders] Re: Use a Popup as itemEditor in Datagrids
My first thought: I would probably write a simple component that serves as an itemRenderer. From within that component I would be to launch a modal popup window from the itemEditBeginning event. Ensure that you pass the row and the dataGridColumn (much like a labelFunction) to the new popup. Have it do whatever it is that needs to be done. Then listen for the popup to close and manually handle the update to the collection through the renderer by listening to itemEditEnd. This is just a high level thought. There are some other details, but the concept would probably work with a bit of tweaking. --mike --- In flexcoders@yahoogroups.com, fritzdimmel [EMAIL PROTECTED] wrote: Hi!

[flexcoders] Re: Accordion initialization problem
In flex, children are generally not created until they are actually
needed, which generally translates to: when they are displayed on the
screen. This keeps startup time and memory use down as, on average,
most users do not navigate to every corner of an app.
As suggested, you could set the creationPolicy to all, which would
cause all of the children to be created in that container on startup,
altough your app will startup slightly slower.
Understanding the creation order, combined with some testing, for example:
if ( foo ) {
Alert.show(foo.text, 'test', Alert.OK);
}
will get you through without changing the creationPolicy.

When you click any of the buttons, you get the following error:
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
at testProject/::toggleAccordion()
at testProject/___Button1_click()
ONLY AFTER VIEWING the second accordion pane does this go away.
It's as if the children of the accordion pane aren't initialized
until
they are displayed.
What's up with that?
Here's the sample code:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
layout=absolute
mx:Script
![CDATA[

Thank you. Thank you. Thank you. --- In flexcoders@yahoogroups.com, Gordon Smith [EMAIL PROTECTED] wrote: rant Several times a week someone complains that they can't seem to set data into controls on the second, third, etc. pane of a ViewStack, Accordion, or TabNavigator because these controls don't get created until the user navigates to the pane they're on. Inevitably there are multiple replies solving this problem by setting creationPolicy=all. Inevitably I reply that Adobe doesn't recommend doing this because it defeats the entire purpose of the deferred instantiation feature, which is to minimize startup time by not creating visual components until they need to be seen. A much better technique is to use event handlers to get the appropriate data into the controls after they get created. For example, you can use the 'initialize' event on each pane, which won't get dispatched until after that pane's controls exist. mx:Accordion mx:VBox initialize=textInput1.text='Hello' mx:TextInput id=textInput1/ /mx:VBox mx:VBox initialize=textInput2.text='World' mx:TextInput id=textInput2/ /mx:VBox /mx:Accordion Using databinding is another good technique. The bindings will occur after the controls get created. I've never seen a case where it is necessary to push data into the controls before they exist. If you must put the data somewhere in the meantime, store it in data vars, which have none of the startup cost of a visual component, and then move it into the controls after they get created. /rant - Gordon, the Flex framework engineer who designed and implemented the deferred instantiation feature, so listen to me on this one! -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

[flexcoders] Re: A web survey based on Flex
Okay, so a few things. A Shared Object can store things that are more complicated than name value pairs. In fact, it can store complex data structures, but not things like methods or typed value objects. That said: You could store your data in a value object in the application. That value object could be written to disk in a shared object. Then you could load that shared object later and convert it back to a value object using something like : http://www.darronschall.com/weblog/archives/000247.cfm - by Darron Schall If this doesn't make sense, email me off the list and I will be glad to help walk you through it. --Mike --- In flexcoders@yahoogroups.com, advantexllc [EMAIL PROTECTED] wrote: --- In flexcoders@yahoogroups.com, Michael Labriola labriola@ wrote: Overall it is not a bad way to proceed.

[flexcoders] Re: filterFunction between ViewStack MXML components
If I understand your question correctly (and I am not sure that I do),
I would personally put your filter function in the file that currently
calls the HTTPService and gets the result. Unless you are using one of
the, or your own, common frameworks, most people seem to put this in
their main application file.
Depending a lot on how your code is constructed, you can probably
apply this filter function in the result handler for your HTTPService.
If I am missing the point, or your setup is more complex, let me know.
As an aside, please take a look at the refresh method of the
ListCollectionView. If you are not actually replacing the whole
collection, you could use this to simply apply the filter.

[flexcoders] Re: e4x expression passed as string
Diego,
Here is a starting point. There are probably bugs, it is bloated,
and it is not completely tested, however, it is a starting point.
A final version of this, along with some actual example code, error
handling and other dynamic tools will eventually be available in a
devnet article.
Used as follows:
import net.digitalprimates.utils.E4XParser;
var parser:E4XParser;
parser = new E4XParser();
var returnXML:XMLList;
//Use parser.evaluate( data:XML, expression:String );
returnXML = parser.evaluate( myXML, '..item.(@id==2)..price' );
If you find a bug, let me know off list.
BTW, thanks on this and future releases also go to Alex Harui who
started this pet project before I. (Although none of the blame for
the bad code that currently permeates it)

[flexcoders] Re: Data in ViewStack Component
Okay,
So, a few things:
#1) your TvView component must have either a property or a
getter/setter method to hold the data from the collection. So, for
example, you might have a bindable public property inside of TvView
called
[Bindable]
var myDataProvider:ArrayCollection;
Then inside of the TvView component, your horizontal list would use
this variable as its dataprovider.
So
mx:HorizontalList dataProvider={myDataProvider}/
Then, inside of the MXML file that you posted, your TvView component
would be called like this:
mx:ViewStack width=100% height=80% creationPolicy=all
TvView id=tvView label=TV myDataProvider={epCollection}/
/mx:ViewStack
Does that make sense?

Essentially, it allows you to convert any plain old object into a class

import com.darronschall.serialization.ObjectTranslator;
// Define an object with properties that mimic the variable names

// Convert the generic object into an instance of the Book class
var book:Book = ObjectTranslator.objectToInstance( bookObj, Book )

Originally it was written so that JSON behaved more like RemoteObject
(returning class instances from the server instead of just plain
objects), but the method is generic enough to be useful in a lot of
situations.
Hope that helps...

I am a newbie to flex... using flex 2 builder and cfmx 7.0.2. I have my first project to be done in flex -- a fairly large web survey. So far I've built the UI using a ViewStack... each canvas has one or more related questions. There's a previous/next button row at the bottom, and I eventually need it to work in such a way as to not allow NEXT to be clicked unless all fields on the canvas are filled in. My MXML file is huge, but one design goal I had was to have the entire survey be loaded by the user, and not communicate with the server again until the user has made choices on all fields and is ready to submit. This way, I'm hoping I can try to capture the data in the event that the user has an internet problem and let them try again or save their choices to an XML file and either email it or upload it later when they are back online. This is a nice thing to do for the user, since the survey is so long. I just want to prevent the survey from being interrupted, since it's so long. If the entire survey is loaded when the person loads the swf, and I can just attempt to send one survey object back to the server at the end, I can trap errors and provide another route to go. I was going to use mx:Form to build the forms on each ViewStack Canvas... one form for each canvas, but still all bound to a single Survey object, as follows... So then I created a Survey.xml file that I was going to use with mx:Model, and try to simply create an xml tree representing a Survey object, it's metadata (startDateTime, endDateTime, IP address, etc.), and it's questions and answers. My thought was that I could populate this Survey object as the user progressed through the ViewStack, and then send the entire object to the server when complete, and if that failed, ask them to try again or offer to save the XML file to their system for later upload or emailing.

[flexcoders] Re: Convert Object to a Value Object
2 more things to consider. Not sure of your particular setup, but, you may want to look at the [Managed] metadata tag. Setup dependent, it may be what you are looking for. Second, and more generally, casts fail when the system cannot convert one type to another. So, take a look at your objects. You mentioned setting the params one by one, a common technique is to build a static method which accepts an Object and returns (by internally assigning the properties) your value object.

Luis,
I agree it would be a good feature. Just as an FYI, I submitted it

On a side note, next week I will be back at the office, and I will

[flexcoders] Re: TextInput control (displaying CurrencyFormatted data) question
Mike, There are a bunch of ways you can approach this some more elegant than others. Let me give you a few hints: #1) There is a method of the NumberBase class called parseNumberString which will parse apart a formatted number string and give you back something you could work with...It is used within the CurrencyFormatter to convert what the user enter into a number so that it can be formatted. So, one approach, you could format on a focus out and populate your value object by parsing the number first... This might be the route of least resistance #2) You could create an extension of the TextInput called, let's say CurrencyInput. You could add a property to that class for an unformatted version of the text property. So, on valueCommit or focusOut you could convert the string to a number and save it in the new property. This property could then be configured as bindable and used instead of the text property in your databinding. The latter is the approach I would prefer, as it makes the setup reusable. However, your mileage will vary depending on type/size of project. There might be another way that I am not familiar with, however, this should work.

[flexcoders] Re: does FLEX2 support text direction right to left?
Unfortunately, no. This is an area where I have spent countless hours trying to work around. Flash player has absolutely no support for right to left natively. Further, while you can manually do *some* things to fix this, ultimately none of the text components (input, area, etc) allow editing in RTL. So, you can *display* RTL text, however, you can not actually edit it. Adobe has some suggestions for workarounds. However, they all require a significant amount of work and none can be accomplished directly in flash player in a real-time environment. Sorry. This is an issue which has been the subject of countless debates and is really limiting the ability to use Flash as a serious development platform for true international solutions.

I do encourage you to spend a little time reading about Object

tutorial. It will help you immensly.

Hello,

I've created a file CommonFunctions.as in the root of my application

package {
public class CommonFunctions {
public function String2Date(doString:String):Date {
var doYear:int = Number(doString.substr(0,4));
var doMonth:int = Number(doString.substr(5,2));

var myDate:Date = new Date(doYear, doMonth, doDay,

doSec);
// showErrorDialog(doString + + + doYear + + +
doMonth + + +
doDay + + + doHour + + + doMin + + + doSec);
return myDate;
}
}
}
Now, how do I use in it on an other mxml-file in that application ?
This does not work:
dfShipping.selectedDate =
String2Date(x.result[0].shipdatum[0].toString());
Thanks a lot,

[flexcoders] Re: Binding a List to an Array
Steve,
Do me a favor and test something out. Make the items Array an
ArrayCollection on your own.
Here is the gist: When you pass an Array to either ComboBox or List it
makes an ArrayCollection out of it for the purposes of binding. List
does something slightly different in that it stops listening to the
existing collection first. This may mean nothing at all.
However, I am concerned that you are getting lucky on the timing of
the ComboBox. This is just a guess, but try it and post back some code
if it does not work, I will be glad to look at it.
Mike

I have a binding problem that seems simple, but I can't figure it out.
Here's the deal:
I have a class that I'm using as my model. It looks like this:
[Bindable]
public class MyModel
{
public var items:Array = new Array();
}
I have a class whose objects populate the array:
[Bindable]
public class MyItem
{
public var name:String;
}
I declare an appModel variable in the MXML (with the appropriate
xmlns:local=* to make it work):
local:ChoreAppModel id=appModel/
When the app starts up I put a few test items in the array:
var anItem:MyItem = new MyItem();
anItem.name = Test 1;
appModel.items.push(anItem);
anItem:MyItem = new MyItem();
anItem.name = Test 2;
appModel.items.push(anItem);
Now, if I create a ComboBox and bind it thusly:
mx:ComboBox labelField=name
dataProvider={appModel.items}/
It works: I see Test 1 and Test 2 in my ComboBox. But if I bind it
to a List:
mx:List dataProvider={appModel.items} labelField=name/
I see nothing. Funny thing is, if I create a global array and bind
the list to that, it works. So it seems to have something to do with
the fact that the array is a property of appModel.
What am I missing?
Thanks.

[flexcoders] Re: Multiline ComboBox
Michael,
Problem is that ComboBase uses a textInput control to display the
currently selected item. The TextInput is limited to displaying a
single line of text.
You could certianly change this, but, it seems as though it will
require extending ComboBox, not just making an itemRenderer.

In your result handler, function that is called once the read is

Frank, The problem is that the dateField is looking for a Flex Date object. Guessing from the conversion to XML, the x.result[0].arrivaldate[0] is an XML node which contains a String.

It really didn't hit me, to oversimplify my original design like that...
Since I am a pretty experienced programmer, I immediately jumped into
the more advanced methods of performing this type of task -
I had written custom classes, one for the itemRenderer and one for the
itemEditor - and I had lots of code/listeners setup to react to the
proper events. Specifically, the DataGrid_ItemEditEnd event - which is
used extensively for this type of thing.
My guess, is that I got things so over complicated, that I was unable to
track down what the true problem was.
I will use your example though, and then re-write all my Classes, so it
performs the exact same functions. Hopefully, I will then get it to
work MY way.
There is absolutely nothing wrong with your methods - in fact, I
