[flexcoders] Poor man's PUSH technology (aka reload data using timer)
I am building a internal app for my company, where we would eventually pursue FDS for it's push capabilities - updating the users view when backend data changes. Until then, I'm thinking about making a function that will get triggered by a timer, e.g. every 60 seconds, it should retrieve data from the server and then compare it to the data currently displayed in the app [Binded]. Then if data has changed, it should update the specific data in the ArrayCollection. Any pointers to how I could accomplish this ? Im thinking a function dataTimer that would call a function getData, that function would then compare each row in the dataset to the data currently in memory in the app. If there's a difference, it would update the data OR completely replace the currently used dataset. (only I guess that would make the app flicker?) Any help is greatly appreciated. Thanks, Mark

Subject: [flexcoders] Returning 'this' from an overridden method?
Please pardon this simple-minded question from an AS3 novice.
My base class often returns 'this' from methods which makes it
convenient to write code like:
camera.move( 10, 12 ).rotateX( 45 ).rotateY( 90 );
The problem comes when code extends the base class and overrides one
of these functions. The compiler insists, correctly, that the return
type of an overriding function must match the one in the base class.
What I want to do is return the 'this' object that is of the type of
the derived class. Is this possible?
The following is a contrived example to demonstrate. It won't
compile because the overridden function in the derived class wants to
return a type of MyCamera rather than Camera:
This is the correct behaviour. The derived class is MyCamera and any
reference to this, either in the derived class or it's parent will be
working with an object of class MyCamera not Camera.
Make the return type Camera, then it will work. You will be returning an
object reference of class Camera, but in fact it is an object reference to
an object of class MyCamera. You can then cast it elsewhere as a 'MyCamera'
in the application.
The problem is that you are trying to change the signature of the method
that you are overriding.
Paul
public class Camera
{
var x:int = 0;
var y:int = 0;
public function move( x:int, y:int ) :Camera
{
this.x += x;
this.y += y;
return( this );
}
}
public class MyCamera extends Camera
{
override public function move( x:int, y:int ) :MyCamera
{
super.move( x, y );
if( x 0 ) x = 0;
if( y 0 ) y = 0;
return( this );
}
}

I think that Adobe should seriously consider revising their licensing to work on multiple platforms. one would think so, yes, especially since what we're talking about is just a plug-in to a cross-platform (and free) IDE. There are plenty of people that own Mac laptops and Windows desktops and would love to have the chance to run Flex Builder on both without having to resort to solutions like Parallels or Boot Camp. not much flamin' good if the Mac is a PPC G4! At any rate, these guys at Adobe have been very helpful in getting to the bottom of our issue. can I ask if there is a resolution? it looks like I'm just about to end up in this situation. thanx
Re: [flexcoders] Poor man's PUSH technology (aka reload data using timer)
Hi Mark, Although I have no experience with this process, the following came to my mind when pondering the same issue as yours. My plan was to keep a history table which tracks all of the updates and additions to data (would be simply recording row ids - not the entire row), and records a timestamp of when it was changed. This functionality would be coded into the server-side code. You would also need a sessions table to track a last synced timestamp for each user, which would be updated with the current timestamp on each sync of the data. Every 60 seconds or so you would poll the server and it would return all of the rows that were either changed, added or deleted since the last synced timestamp. Once that data is delivered back to flex, simply loop through the data on the client side and replace the rows where the id's match, add a row if it's new, and delete the row if it's deleted. You'd probably also want a cron cleaning up the history table periodically, depending on how many users there are and how frequently data is updated. From my perspective, this would be a pretty fast operation all up. You could even optimise the SQL query so that it joins the history table id's to the data table. As long as all steps go smoothly, the data should always be current (within 60 sec window of course). The only real hurdle I see is that your app needs to know which id's are updated. This might not be a problem if you update and delete items based on id's, but if you do something like [delete from mydata where name = 'fred'], you will need to know the id's before deleting them. I hope that gives an insight to how I would tackle the problem. Any others want to give feedback on this method?

It is a pain to specify all of the jar files and keep that up to date in my case since the jars change a lot (though I have gotten that to work too...). Unfortunately the exact way is dependent on the app server and I am still using jrun (yeah, been meaning to switch for a while!) For Jrun, I add this to the standard java command line args it uses: -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=2005 Then my eclipse debug target is created from the Remote Java Application configuration. I specify localhost and 2005 for server and port. Debug logging on the server is in WEB-INF/flex/services-config.xml. Search for level=, change that to Debug.

[flexcoders] Tree XMLListCollection woes
Hi all, I am trying to dynamically build and display a sorted tree, i.e. create branches/leaves purely in actionscript. I *thought* that using XML would make this easy due to its hierarchical nature and Flex's e4x extensions (which should allow me to easily locate nodes in the tree etc without having to code a load of recursion). An example of the kind of structure I am trying to build looks something like this: group id=1 name=group 1 parent= displayOrder=1 group id=1_1 name=group 1_1 parent=1 displayOrder=1 group id=1_1_1 name=group 1_1_1 parent=1_1 displayOrder=1 / /group group id=1_2 name=group 1_2 parent=1 displayOrder=2 / /group group id=2 name=group 2 parent= displayOrder=2 / group id=3 name=group 3 parent= displayOrder=3 group id=3_1 name=group 3_1 parent=3 displayOrder=1 / /group I am using an XMLListCollection as my tree data provider as this provides the sorting capabilities I need to retain the sort order as I add new nodes. As new group objects come in the plan is to turn them into XML and add them to the tree in the appropriate location (based on their parent attribute). The groups may come in in any order so I make use of the sort ability of the XMLListCollection. After going round in circles for a couple of days trying to get it to work, I found the following article on Peter Ent's blog: http://weblogs.macromedia.com/pent/archives/2006/10/tree_control_da.cf m This has proven invaluable (thanks Peter!). However I am still having problems. In Peter's example he adds top-level nodes via the XMLListCollection's addItem method but child nodes via the appendChild method of the underlying XML/XMLList object. Now, while this allows me to build a tree, the child nodes added directly to the XML are not sorted according to the XMLListCollection's sort order - only the top-level nodes are sorted. Does anyone know how I can build this tree whilst maintaining the sort order? I do not want to hard-code any particular sort function as I want the sort field and direction etc. to remain configurable. Alternatively, is there any way to add child nodes directly through the XMLListCollection object? It surprises me that a collection designed for hierarchical XML data doesn't seem to support this (or e4x for that matter). Why should it be necessary to access the underlying XML data directly to add child nodes (causing the sort order to break)? Somebody please help - this is driving me nuts! Nick.

I believe most of Ely's examples he includes a license or says on his blog that it's Creative Commons.

Re: [flexcoders] Returning 'this' from an overridden method?
Hi David,
I to am an AS3 novice. Wrote my first(trivial) action script file about
an hour ago. :)
A couple of ideas. Not sure if they will be of much help to you, but
incase you hadnt considered them already..
. you could return the value returned by the call to super.
ie)
Camera c = super.move;
//// some local x,y stuff
return c;
. you could use an interface as the return value. eg) interface ICamera
would define the move and rotate methods and return an ICamera and your
Camera classes would implement ICamera.
I realise that these options do not do what you asked for, but you might
find one of these is an acceptable alternative.

Please pardon this simple-minded question from an AS3 novice.
My base class often returns 'this' from methods which makes it
convenient to write code like:
camera.move( 10, 12 ).rotateX( 45 ).rotateY( 90 );
The problem comes when code extends the base class and overrides one
of these functions. The compiler insists, correctly, that the return
type of an overriding function must match the one in the base class.
What I want to do is return the 'this' object that is of the type of
the derived class. Is this possible?
The following is a contrived example to demonstrate. It won't
compile because the overridden function in the derived class wants to
return a type of MyCamera rather than Camera:
public class Camera
{
var x:int = 0;
var y:int = 0;
public function move( x:int, y:int ) :Camera
{
this.x += x;
this.y += y;
return( this );
}
}
public class MyCamera extends Camera
{
override public function move( x:int, y:int ) :MyCamera
{
super.move( x, y );
if( x 0 ) x = 0;
if( y 0 ) y = 0;
return( this );

Re: [flexcoders] Re: Poor man's PUSH technology (aka reload data using timer)
This is some code I have written for a similar project... It simply runs
through the dataProvider searching for a matched id. If it finds the id, then
it replaces the row, otherwise it adds a new row at the end of the
dataProvider. Since you want to track add, update and delete, you'll probably
need to specify another field that is returned with the data, such as
_row_status (0=new,1=updated,2=deleted), and modify the script likewise.
public var dataProvider:ArrayCollection = new ArrayCollection();
public function onUpdateData(result:Array):void
{
var i:Number, j:Number, row:Object, item:Object, id:Number, found:Boolean;
for (i=0;iresult.length;i++){
row = result[i];
id = row.id;
found = false;
for (j=0;jdataProvider.length;j++){
item = dataProvider.getItemAt(j);
if (item.id == id){
dataProvider.setItemAt(row,j);
found = true;
break;
}
}
if (!found){
dataProvider.addItem(row);
}
}
dataProvider.refresh();
}

Hi Adam.
Thanks for your reply - I like your idea about keeping the pushed
data to a minimum. My original idea was to get the entire dataset and

I'm really in need of some examples of a timer function, and perhaps

That's usually the point of the singleton pattern, that it provides a global access point for a variable (as well as enforcing a single instance of a class).

Re: [flexcoders] is there a way to run Applet in Flash
The only way is to fake it by having the surrounding HTML webpage float an IFRAME over your Flash applet.

I believe the Flash player allows for a transparent background (I guess that's how all of those annoying integrated page ads work), so you could probably float your Flash app over your Java applet as well!

[flexcoders] Resources to Flex Application Architecture articles?
Hi everybody, we are looking for (online) resources related to how to best structure (larger) Flex applications. Most of the great training and tutorial material available tends to focus on how to construct more complex controls, how to implement special effects or how to solve DataGrid/Binding related issues, however, what we are seeking is material as to potential best practices about how to structure an Flex app best. Should AS code be used inline primarily? Or is a code-behind pattern a better choice? Should we ultimately keep the primary MXML application file small and work with complex custom controls, or should we keep custom controls usage low? Are there any good technical articles out there? Any links? Any hints? Thanks for your support.

You can make as many calls to addEventListener as you want. So you can add 2 or more event listeners that get triggered for the same event. So something like: myButton.addEventListener(MouseEvent.CLICK, myFunction1); myButton.addEventListener(MouseEvent.CLICK, myFunction2); myButton.addEventListener(MouseEvent.CLICK, myFunction3); All three of the above functions would get called when the event triggers. You can remove each of these separately as well by using removeEventListener and specifying the particular function you want removed.

[flexcoders] Re: Returning 'this' from an overridden method?
Just from first glance I'd suggest not following the design pattern of
returning the object from the function like you're doing. It seems
like the only reason you're doing it is to make it so you can write a
bunch of statements all on one line. In terms of someone else reading
your code, I think it would make a lot more sense if they saw this:
camera.move(10, 12);
camera.rotateX(45);
camera.rotateY(90);
It turns 1 line into 3 lines, but I think it's far less confusing and
this follows the same design pattern that most other Actionscript
classes follow. Methods like move, rotate, etc are used often in
various classes and usually they do what they're supposed to do and
return void. In my experience I've never really seen an OOP class that
returns itself very much.
So that's not a direct answer to your question, merely a coding
suggestion.
Doug

Please pardon this simple-minded question from an AS3 novice.
My base class often returns 'this' from methods which makes it
convenient to write code like:

The problem comes when code extends the base class and overrides one
of these functions. The compiler insists, correctly, that the return
type of an overriding function must match the one in the base class.
What I want to do is return the 'this' object that is of the type of
the derived class. Is this possible?
The following is a contrived example to demonstrate. It won't
compile because the overridden function in the derived class wants to
return a type of MyCamera rather than Camera:
public class Camera
{
var x:int = 0;
var y:int = 0;
public function move( x:int, y:int ) :Camera

this.x += x;

Re: [flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML
Object.addEventListener( click, [funct1, funct2, funct3] ); No, 1. as3 is strongly typed which means the method expects a function when it is getting an array. 2. addEventListener wouldn't even know what to do with an array. You could, if you had your own subclass override addEventListener to do that but, you could also just create a stack of functions in an array if they were all going to the same event and loop through them to save code lines.

Re: [flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML
Nope, I think the second parameter must be a function, trying to pass an array of functions should fail. Also, just a note: it's better practice to not use the string of the event listener like click but rather the variable like MouseEvent.CLICK. They really do the exact same thing in practice, but it's possible that within MouseEvent the click event could be renamed in a future release to something like mouseClick and then your code wouldn't work.

The other, and more common reason is that more than one module is using the DragManager, but the main application does not.. Modules operate in their own application domain, and thus cannot share singletons unless that singleton is loaded by the parent application domain. The simple solution is to link the DragManager into the main application by putting something like this in a script block import mx.managers.DragManager; var dm:DragManager; This fattens your application a little. More complex solutions involve loading the DragManager into the main application's application domain.

[flexcoders] 2nd datagrid - no headers, wrong size
I've been spending a lot of time trying to overcome this issue without any success. Hopefully someone out there has a suggestion. I have datagrid within a vbox in a component. The grid takes up as much space as is available (height='100%'). There is another state which does the following: 1) reduces the height of the 1st datagrid to a fixed value (344) 2) adds a 2nd datagrid (height='124') into the vbox as the lastchild. The problem is when the state gets switched and the 2nd datagrid gets added.. 1) the headers are missing 2) the requested size is not honored When looking at the state in design mode, the headers are present and the size of the 2nd grid is correct. Has anyone run into issues similar to this? Any resolutions? The code is rather long, but I will post it if anyone is interested. Thanks
RE: [flexcoders] Returning 'this' from an overridden method?
The short answer is that there is no way to do what you want for the
time being.
What you are looking for is a language feature called covariant return
types. In certain languages (C++, Java) you can have your subclass
redefine the type that is returned by a method.
This would be a great thing to get into the AS language, but it is not
there now. There are further wrinkles when you consider how you would
extend properties in a similar way (I wrote about the issues at
http://kuwamoto.org/2007/01/22/covariant-property-types/).

Please pardon this simple-minded question from an AS3 novice.
My base class often returns 'this' from methods which makes it
convenient to write code like:
camera.move( 10, 12 ).rotateX( 45 ).rotateY( 90 );
The problem comes when code extends the base class and overrides
one
of these functions. The compiler insists, correctly, that the
return
type of an overriding function must match the one in the base
class.
What I want to do is return the 'this' object that is of the
type of
the derived class. Is this possible?
The following is a contrived example to demonstrate. It won't
compile because the overridden function in the derived class
wants to
return a type of MyCamera rather than Camera:
public class Camera
{
var x:int = 0;
var y:int = 0;
public function move( x:int, y:int ) :Camera
{
this.x += x;
this.y += y;
return( this );
}

[flexcoders] RemoteObject over HTTPS / SSL
I have been working on this for a few days and I am stuck. I have an
application that is using the Cairngorm Framework and I create 2
RemoteObjects. I got these RemoteObjects to work by relying on the
default services-config.xml file on the server (which I don't have
access to) and by simply creating a Basic Project in Flex Builder 2 with
no compiler options and defining the endpoint
(http://SERVER/flex2gateway), destination (ColdFusion), and source (dot
path to cfc).
Now here is my problem. One of my RemoteObjects needs to be over SSL
since it is handling the authentication for the application while the
other one does not and we would like to access the application by just
going to the standard http address (I was using dummy data when logging
in before since it wasn't over HTTPS). We achieved this in the Past in
Flex 1.5 by creating the RemoteObject with the Protocol attribute set to
https and it was working in 1.5. Since Flex 2 no longer supports the
protocol attribute, I tried changing the endpoint to
https://SERVER/flex2gateway. I build the project and then open the HTML
file (in IE) the compiler creates in the bin folder and I get an error
Send Failed, Channel.Connect.Failed error NetConnection.Call.Failed:
HTTP: Status 500. I get this error when trying to load the html or SWF
directly over HTTP and HTTPS and also in Firefox.
So, a co-worker sent me this link
(http://www.simb.net/client/index.cfm/2007/2/2/How-I-create-a-Flex-Proje
ct-with-ColdFusion) where it says to use a local services-config.xml
file and add the compiler option. So I got one of the server admins to
send me the file and I created libs/services-config.xml in my project
and added -services libs\services-config.xml to my compiler arguments.
I first tried the normal http remoteobject method and it works just like
before, then I changed the endpoint to https like I did before using the
server's config file and I get the same behavior as before.
Next, I read that I probably have to create a channel definition for the
SecureAMFChannel. So edited the current AMF channel definition to read:
channel-definition id=cf-secure-amf
class=mx.messaging.channels.SecureAMFChannel
endpoint
uri=https://{server.name}:{server.port}{context.root}/flex2gateway/;
class=flex.messaging.endpoints.SecureAMFEndpoint/
properties
add-no-cache-headersfalse/add-no-cache-headers
polling-enabledfalse/polling-enabled
serialization
instantiate-typesfalse/instantiate-types
/serialization
/properties
/channel-definition
I also made sure to change the name in the channels tag in the
destination declaration of the xml file. Then I changed the endpoint in
my remoteObject declaration to https://SERVER/flex2gateway and I still
get the NetConnection error when loading the app over both http and
https and in both IE and FF. Again ideally, we want to have 2 channels
one over SSL and one standard, but I can't even get SSL only to work.
So at this point I am thinking there must be something on the Server
that needs to be changed but I am not sure what to tell the admins to do
and no one else at my work is ready to publish a Flex 2 so I am the
first person to attempt to solve the SSL problem.
Any thoughts and thanks,
John

[flexcoders] basic exception handling
All,
When I am catching exceptions the catch seems to be ignored and the
actionscript error window pops up. For example if I have a simple
service like this:
mx:HTTPService
id=simpleService
url=http://example.com/someservice/;
useProxy=false
method=GET
And I have a try catch block like this with one statement inside. If I
comment out this statement no errors...so I know this statement is
causing the error:
try {
simpleService.send();
}
catch(errObject:Error) {
trace(Error +errObject.message);
}
The scenarios that throw errors (for example TypeError: Error #1034)
opens the actionscript error window and the trace does not appear.
What do I need to be doing so the exception is consumed in the catch
and no error window? Thanks,
Dan

What you are looking for is a language feature called covariant return

redefine the type that is returned by a method.
This would be a great thing to get into the AS language, but it is not
there now. There are further wrinkles when you consider how you would

Subject: [flexcoders] Returning 'this' from an overridden
method?
Please pardon this simple-minded question from an AS3 novice.
My base class often returns 'this' from methods which makes it
convenient to write code like:
camera.move( 10, 12 ).rotateX( 45 ).rotateY( 90 );
The problem comes when code extends the base class and overrides
one
of these functions. The compiler insists, correctly, that the
return
type of an overriding function must match the one in the base
class.
What I want to do is return the 'this' object that is of the
type of
the derived class. Is this possible?
The following is a contrived example to demonstrate. It won't
compile because the overridden function in the derived class
wants to
return a type of MyCamera rather than Camera:
public class Camera
{
var x:int = 0;
var y:int = 0;
public function move( x:int, y:int ) :Camera
{
this.x += x;
this.y += y;
return( this );
}
}
public class MyCamera extends Camera
{
override public function move( x:int, y:int ) :MyCamera
{
super.move( x, y );
if( x 0 ) x = 0;
if( y 0 ) y = 0;
return( this );
}

RE: [flexcoders] basic exception handling
Right, the requests made by HTTPService are asynchronous... so you have
to wait for events to be dispatched some time later. Any errors that
occur prior to actually sending the request are typically caught and
dispatched as fault events too so there shouldn't be a need for a
try/catch.

[flexcoders] How do i determine when all rendering is complete for added objects in for loop
I'm parsing an xml document and adding child objects to a VBox. The child components all have a text component which receives text that is set to the htmlText property. So depending on the text the height of the control varies. However, i need to know the height of each control i'm adding (for printing reason) but i have no idea how to get it right away, at least when it's added to the VBox, ideally at least. I've tried listening to the updateComplete and creationComplete listeners to each control added, then in theory when I handle the event i know the object is done and i can finally use the object.height property to get it's height in pixels. If you attempt to the the object.height proprety to early you get zero or something that is not reflective of the final height. However, listening to the updateComplete, you get multiples calls because it's dispatched several times throughout the creation of the child object... how do you know which one is the last one? this may not even be the best way to do it. The creationComplete is only sent once but it's sent before it finishes rendering the text box which controls the height. So without intentionally waiting a few seconds for the components to load, how or when can i be sure all the child components have finished sizing themselves from which I can get a true height value from them? Hopefully this makes sense, i'm not quite even sure what to search on. I'm a newbie to flex and love it so far, main expierience in asp.net.

[flexcoders] any interest in an alternative to QTP to automate Flex apps?
Automating functional tests is critical to the way we develop software at my company. And there are two big things that stop us from using QTP. 1) It's record and playback - we want to write test scripts 2) It costs a lot of money - we want a tool that is free and community driven At my company we are writing several applications in Flex2 and are building out an as3 library that allows us to write test scripts in as3 to drive the Flex ui as if the user was interacting with it. If you are familiar with the Java Swing testing tool called Jemmy, it's very similar in design. Is there any interest out there for a tool like this? I am about to create a sourceforge project, but first wanted to get a feel for the need. Thanks, Brian

Have you determined that model.treeData contains valid xml?
(trace(treeData.toXMLString())) If it does, then the tree should work
like you have it. You will need to set the labelField property for
the label, or use a labelFunction if the data you want for the label
is
not a top-level porperty/attribute of the item node.
Also, I am not familiar with RemoteObject, so this may not apply, but
you may need to set resultFormat=e4x. Also, if the data service was
HTTPService, I would do the result handler like this:
public function result( event:ResultEvent ):void {
var xmlResult:XML = XML(event.result);
trace(xmlResult.toXMLString());
model.treeData = xmlResult;
}
if you see good xml but are still having difficulty, take the model
class out of the picture and assign the dataProvider directly:
acTree.dataProvider = xmlResult;

Subject: [flexcoders] Re: Populate Tree with data from a query?
Hi,
That helps a bit, in my tree I am seeing the actual xml when I run my
application in flex. I have CFC function returning a string, I tried
having return xml and same thing.
***
After I make my remote object call in my result handler I have this:
public function result( data:Object ):void {
var event:ResultEvent = data as ResultEvent
model.treeData = event.result as XML;
}
It seems I have to cast it as XML otherwise in my model I get a
'type'
error
**
In my model which is a [Bindable] class I have:
public var treeData:XML;
**
And in the view I have
mx:Tree id=acTree
width=50%
height=100%
showRoot=false
dataProvider={model.treeData}
change=treeChanged(event)
/
Any help appreciated as I am getting the actual xml in the tree. How
do
you get the label to work also?

Hi Malik,
I have never exactly populated a tree with straight query data, i
usually convert it to xml first within the cfc that i'm calling, and
i
return a string from that cfc... it took some playing with but i
eventually got it...
google the following:
using cfxml returning it to flex? or something along those
lines...
that will teach you how to convert your query to xml... but the
thing
is, flex doesn't want the actual xml doc from coldfusion, it wants
the
valid string format...
here is my example
http://axel.cfwebtools.com/index.cfm/2007/2/6/Returning-a-query-to-flex-

as-xml#more
http://axel.cfwebtools.com/index.cfm/2007/2/6/Returning-a-query-to-flex
-as-xml#more
once you get it into flex, it will be declared as xml, and then in
your mx:Tree your going to declare a showRoot=false
the blog might be a little hard to follow, but I hope it helps.

RE: [flexcoders] WARNING: css type selectors are not supported in components?
Is your mx:Style src=style.css tag inside an mx:Application tag or
inside something like mx:ApplicationShell?
If it is the latter, I think the MXML compiler thinks
mx:ApplicationShell is a component rather than an application.

OK, that'll work, but I'll have to add new components I make to the

I don't think there's a good answer to this question. There's no way
to figure out via AS whether a component MIGHT dispatch a given event.
I did a search on livedocs to try to find all classes that dispatch a
change event. This only seems to include base classes, so subclasses
of any of these controls won't show up, so you'd hve to figure those
out. Also note that this doesn't mean that some classes might dispatch
other events that signify change that aren't specifically the same
change event. And these change events don't necessarily mean user
input either. All it means is that the component dispatches an event
called change.
Here's the livedocs search:
http://livedocs.macromedia.com/cfusion/search/index.cfm?loc=en_usterm=site%3Alivedocs.macromedia.com%2Fflex%2F201++%22change%3DNo+default%22action=Search
And here are the classes that come up:
mx.controls.RadioButtonGroup
mx.controls.sliderClasses.Slider (which means HSlider and VSlider as
well)
mx.controls.ColorPicker
mx.containers.Accordion
mx.containers.ViewStack
mx.controls.DateChooser
mx.controls.NumericStepper
mx.controls.Button
mx.controls.DateField
mx.controls.PopUpMenuButton
mx.controls.ComboBox
mx.controls.TextInput
mx.controls.TextArea
mx.controls.Tree
mx.controls.listClasses.ListBase (so that would mean all list controls
like List, TileList, DataGrid, etc)
So your best bet is probably to put together a more complete list of
each component you want to define as having user input and then just
check against that list using the is test as already mentioned. But
I think the basic answer to your question is no, there's no good way
to do this.

Is there a reliable way of detecting a user editable control?

Hopefully someone out there has a suggestion. I have datagrid within a vbox in a component. The grid takes up as much space as is available (height='100%'). There is another state which does the following: 1) reduces the height of the 1st datagrid to a fixed value (344) 2) adds a 2nd datagrid (height='124') into the vbox as the lastchild. The problem is when the state gets switched and the 2nd datagrid gets added.. 1) the headers are missing 2) the requested size is not honored When looking at the state in design mode, the headers are present and the size of the 2nd grid is correct. Has anyone run into issues similar to this? Any resolutions? The code is rather long, but I will post it if anyone is interested. Thanks Well, to answer my own question (and for the sake of anyone else who see symptoms like this) - the problem was the use of a transition. When the new state was displayed a Resize transition moved from a height of 0 to a more normal size height (170). For some reason, the headers of the datagrid got lost in that transition. Once I removed the transition, it behaved as expected. I suppose there is a way to still use the resize transition without losing the headers however that's for another day.

Oh yeah one more thing. I know why they did this. At least a perspective. If you have version 2.0 linking in ManagerA and they change the implementation to ManagerB in 2.5, ManagerA will not be linked in unless ManagerA is linked, other wise ManagerB is linked in, in 2.5 and the string decouples the dependency of ManagerA in the last version. may be wrong here but it makes sense to me.

I've posted on here before about this topic. I think this is something that lacks in the Flex community. Just curious if you or your company have looked at a product called imacros.

Re: [flexcoders] any interest in an alternative to QTP to automate Flex apps?
I am pretty sure there is and will be a lot of interest in opensource automation tools for Flex. QTP works great with the plugin setup for flex and everything, but the price paid for the same is a weaking factor for the product. Its like needing to have FDS for QTP, which albeit having a lot of capabilities, is not really something i would want to pay for just the functionality of QTP. I hope and guess that there are already steps in place from Adobe to look into the issue where in QTP could be used without having to pay for FDS. As for getting the functionality of QTP without having to pay the cost, who wouldnt be ready to try it? I would. -RM On 2/7/07, Allen Riddle [EMAIL PROTECTED] wrote: I've posted on here before about this topic. I think this is something that lacks in the Flex community. Just curious if you or your company have looked at a product called imacros. I downloaded the demo and it was pretty decent. It's a lot cheaper than QTP. It also lets you script out tests. I've also wondered if it was possible to get Ruby's Watir tool to work with Flex, that would be my first choice if so. Cool suggestion, we'd use it. -- *From:* flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] *On Behalf Of *Simeon Bateman *Sent:* Wednesday, February 07, 2007 3:56 PM *To:* flexcoders@yahoogroups.com *Subject:* Re: [flexcoders] any interest in an alternative to QTP to automate Flex apps? I am interested in this. I had been playing with the thought of using the FA Bridge to allow you to use Selenium to test your applications. Then you could use the Firefox plugin to record our actions and test the movie. Not sure how feasible it is but even that would start with having a testing framework in flex to tie into. simeon On 2/7/07, *brian.knorr* [EMAIL PROTECTED] wrote: Automating functional tests is critical to the way we develop software at my company. And there are two big things that stop us from using QTP. 1) It's record and playback - we want to write test scripts 2) It costs a lot of money - we want a tool that is free and community driven At my company we are writing several applications in Flex2 and are building out an as3 library that allows us to write test scripts in as3 to drive the Flex ui as if the user was interacting with it. If you are familiar with the Java Swing testing tool called Jemmy, it's very similar in design. Is there any interest out there for a tool like this? I am about to create a sourceforge project, but first wanted to get a feel for the need. Thanks, Brian
[flexcoders] Re: navigateToURL bind to datagrid selecteditem
I would do this in a function rather than in mxml.
function doNavigate( ) : void {
navigateToURL(new
URLRequest(http://www.mydomain.com/synapse/data/7117/documents/; +
drivergrid.selectedItem.uploadedfile, Download));
}
...
mx:LinkButton label=Download click=doNavigate() ... /

I have a linkbutton called Download
The downloaded filename is in a datagrid column called uploadedfile.
This uploaded filename varies, but the path stays the same
www.mydomain.com/synapse/data/7117/documents/#uploadedfile#
When the user selects a row in drivergrid, the driver details appear
below the grid with a Download linkbutton.
When the user clicks the download button, I want the driver file to
begin to download.
I don't know how to write the url below so that it binds the
uploadedfile to the end of the url.
This doesn't work.
mx:LinkButton label=Download click=navigateToURL(new URLRequest
('http://www.mydomain.com/synapse/data/7117/documents/
{drivergrid.selectedItem.uploadedfile}'), 'Download')/
Will anyone help with the correct syntax?
Also, how would you do a url parameter in a similar way?
Thanks,
Don
