Hi Matt,

I send this call to arms to some expert linux people to see if they are
interested or know other linux guys that would be interested as well.

Best,

Re: [flexcoders] Function Error

[Lachlan Cotter]

Your validateForm() function tries to call a method on a variable  
which is null.  I'm not sure exactly where you have gone wrong as  
your example code is incomplete. Set a break point in the validateForm 
() function and run it in the debugger so you can which line throws  
the error.

[flexcoders] List component and state change events

[Lachlan Cotter]

Hi,

I have a List control with custom item renderers. The renders have  
two alternate states and I am using a transition to move between them.

The problem seems to be that when the list is scrolled, state change  
events get fired on the renderers which have just come into view. I  
think I remember reading that the list controls only use enough  
renders to display the items which are actually visible at any point,  
so I am guessing it has something to do with this.

The consequence is that the transition gets fired on those renderers  
even though no actual state change has occurred.

Any ideas?

Lach

[flexcoders] Returning values from objects on another canvas

[michrx7]

How does one go about referencing objects on another canvas? For 
example I have a tab navigator with 4 tabs:
Register
Attendees
Membership
Payment Options

Inside the attendees tab I have a canvas: csAttendee with a datagrid: 
dgselectedOptions

When the user submits the "pay" button on the payment options tab I 
call a function to validate their input and try and reference the 
columns array for the datagrid dgselectedOptions.

Using csAttendee.dgselectedOptions gives me an error when I try to 
compile of "Access of possibly undefined property dgselectedOptions 
through a reference with static type mx.containers:Canvas."

If I try Attendees.csAttendee.dgselectedOptions gives me "Access of 
possibly undefined property csAttendee through a reference with 
static type mx.containers:Canvas."

If I try just dgselectedOptions it compiles, but when I click my 
payment button it gives: "Cannot access a property or method of a 
null object reference." Even though I can click on the Attendees tab 
and the datagrid is there and populated.

RE: [flexcoders] Re: Mercury QT Pro - LoaderRunner + Flex

[Lance Linder]

Matt, Jun,

Thanks for the information/heads up. There seems to be little too no 
information on this subject so it is good news to hear things are on a forward 
track!

This week I am going to be in a web seminar that Mercury is putting on and I am 
sure I will get lots of info about QT Pro. Depending on the out come of that I 
will get in touch about the beta QT Pro/Flex testing framework.

So far Mercury's products seem the best fit at this time given there is work 
towards both functional GUI testing and possible AMF3 support from one vendor.

Since the services we need to load test are rather simple I am going to look at 
down grading them to AMF0 so that I can use LoadRunner with them today. I 
really do like the Flex Stress Testing frame work as well which I took a look 
at this last Friday and Saturday, however I never did get it to fully work but 
the idea looks promissing :) I think my biggest concern with it (besides 
getting it to work) is how many machines I would need to perform a large scale 
load test (7,000 to 10,000 users with 30-40 small AMF requests each over 3-10 
minutes). I am not totally sure if I even have enough machines available to do 
a test of that size with LoadRunner but I figured it would probably be better 
suited for a larger scale test like this than Flex Stress Testing Framework. 
Can anyone from Adobe comment on the performance of the Flex Stress Testing 
Framework and whether it will scale that high on a dual 3.4ghz 3GB ram box as 
the test server with 20-30 client machines running as many instances of the 
test as physically possible? The system it is testing against is a IIS web farm 
with multiple back end load balanced MS SQL 2005 databases. Since the web farm 
doesn't have FDS installed it isn't an option to use a portion of it as the 
Flex Stress Testing server so I will have to rely on other high end workstation 
for this alone.

Thanks!
Lance

textAlign="justify" works on  and , although it

I'm not sure this is the best answer to your question but as far as I

you can use a TextArea instead.

[flexcoders] removeNamespace() and the default namespace in XML

[shagenlo]

Hello,

I realize this topic was covered a bit in a thread titled "Namespace
hell", however I didn't see a resolution to a lingering question.  Is
there any way to use the removeNamespace() method of the XML class to
remove the default namespace (the namespace without a prefix)?

I would like to do this, because i have an object heirarchy which
represents an unstructured XML document (not a recordset).  In
serializing the object structure, the new XML can get littered with
namespace declares, it would be easier to simply remove the original
default namespace and be done with it.  Name collisions are not a
concern for me, but the fact that removeNamespace() doesn't work with
the default namespace is.  Is there an answer other than RegEx on the
xml string?

Cheers,
Steve

Let me see if I can dig something up.  We have a few applications folks
built internally here that use hibernate with managed associations.  It
may take a bit of cleaning up to get it so they can be given out.

Both of those approaches work and so are correct in a certain sense.
Probably most DBAs would prefer the link table which only has the ids
from the linked tables since that extra id column is not strictly
necessary.  Note that FDMS supports Java/Actionscript objects which have
more than one id property but I think hibernate requires that all id
columns are stored in the same property in Java.  I am not sure about
that...

Thanks for the response. I'm having some trouble applying this to my 
particular case and would like to check a bit to make sure that we're on

the same page.


Here's my question:



If I run HibernateTools on a many-to-many table relationship with a link

table - as shown here: 
http://www.brightworks.com/technology/tech_questions/hibernate_lazy_asso
ciations/index.html 
- it creates a Java file like this:



FilmActor.java

package com.brightworks.apps.dvd_store;

import java.util.Date;

public class FilmActor {

private FilmActorId id;
private Film film;
private Actor actor;
private Date lastUpdate;

public FilmActor() {
}

public FilmActor(FilmActorId id, Film film, Actor actor, Date
lastUpdate) {
this.id = id;
this.film = film;
this.actor = actor;
this.lastUpdate = lastUpdate;
}

public FilmActorId getId() {
return this.id;
}

public void setId(FilmActorId id) {
this.id = id;
}

public Film getFilm() {
return this.film;
}

public void setFilm(Film film) {
this.film = film;
}

public Actor getActor() {
return this.actor;
}

public void setActor(Actor actor) {
this.actor = actor;
}

public Date getLastUpdate() {
return this.lastUpdate;
}

public void setLastUpdate(Date lastUpdate) {
this.lastUpdate = lastUpdate;
}

}




The link table uses actor_id and film_id columns to link to the other 
two tables.

But a FilmActor.java instance has:

a) References to the Actor and Film instances that it is linking
b) An instance of FilmActorId.java. This class obviously acts as the 
"ID" for FilmActor.java and contains ActorId and FilmId values. It's 
described in the mapping file like this:













You wrote:

When you say "complex object type" I assume that you're referring
to FilmActorId. Am I correct so far?

But I run into a problem here:

 > public function toString():String
 > {
 > return actorId + ":" + filmId
 > }


My FilmActor.as looks like this:


package com.brightworks.apps.dvd_store.vo
{
[Managed]
[RemoteClass(alias="com.brightworks.apps.dvd_store.FilmActor")]

public class FilmActor
{
public function FilmActor() {}

public var filmActorId:FilmActorId;
public var film:Film;
public var actor:Actor;
public var lastUpdate:Date;
}
}


I wrote it to simply reflect FilmActor.java's structure.

It has no actorId or filmId, so I can't do "return actorId + ":" +
filmId"

I could add these properties, but I don't see how/why they'd get int 
values from FilmActor.java. Would FDMS or Hibernate know enough to pull 
them out of the FilmActor.java's "complex ID"?

Here's my question:

public FilmActor() {
}

public FilmActor(FilmActorId id, Film film, Actor actor, Date lastUpdate) {
this.id = id;
this.film = film;
this.actor = actor;
this.lastUpdate = lastUpdate;
}

public FilmActorId getId() {
return this.id;
}

public void setId(FilmActorId id) {
this.id = id;
}

public Film getFilm() {
return this.film;
}

public void setFilm(Film film) {
this.film = film;
}

public Actor getActor() {
return this.actor;
}

public void setActor(Actor actor) {
this.actor = actor;
}

public Date getLastUpdate() {
return this.lastUpdate;
}

public void setLastUpdate(Date lastUpdate) {
this.lastUpdate = lastUpdate;
}

}




The link table uses actor_id and film_id columns to link to the other 
two tables.

But a FilmActor.java instance has:

a) References to the Actor and Film instances that it is linking
b) An instance of FilmActorId.java. This class obviously acts as the 
"ID" for FilmActor.java and contains ActorId and FilmId values. It's 
described in the mapping file like this:

My FilmActor.as looks like this:


package com.brightworks.apps.dvd_store.vo
{
[Managed]
[RemoteClass(alias="com.brightworks.apps.dvd_store.FilmActor")]

public class FilmActor
{

public var film:Film;
public var actor:Actor;
public var lastUpdate:Date;
}
}


I wrote it to simply reflect FilmActor.java's structure.

It has no actorId or filmId, so I can't do "return actorId + “:” + filmId"

I could add these properties, but I don't see how/why they'd get int 
values from FilmActor.java. Would FDMS or Hibernate know enough to pull 
them out of the FilmActor.java's "complex ID"?

I also have questions about this but I think I'll hold off for now. Best 
to get the other case working first, I think. Frankly, I don't know 
Hibernate very well. My current learning strategy is to assume that 
HibernateTools is generating reasonably correct code, and to focus on 
learning how to implement the FDMS/H8 connection. Later, I'll be 
learning more about Hibernate.

Two more questions:

1. This would be so much easier if I had a working example to work from. 
I haven't found any examples that use the 'managed associations' 
approach - with one-to-many or many-to-many relationships. Jeff, do you 
know of any? Does anyone?

2. Victor Rubba has been kind enough to show me some code that he has 
that implements a many-to-many relationship with a link table. His link 
table has a numeric id column, which allows his code to avoid the whole 
"complex id" issue. Thus his destination config avoids 'composite-id'. 
Everything is much simpler. :-) (!) But we're wondering if this approach 
is "correct", or if it's more correct to have a link table that only 
contains IDs from the linked tables, i.e. a composite ID.


Thanks,

Douglas

of article on how to use Flex 2 SDK in unbuntu distro.

http://www.igorcosta.com/flex2/flex_2sdk_ubuntu.html

We've done some in 3 parts this is the second I sent you the link. the only
problem to the others at the community it's because wroted in portuguese
version.

So anyway, if you could send some information to his e-mail, it's good, I
will alert him about this.

 When you are deploying a web application (.war), you specify the

to specify a single "default web application", i.e. with a context-root of
"/".   For tomcat, this is in the server.xml file I think.




Yes, this is in the server.xml file. You specify a host element and make the
appBase attribute say "webapps/yourWebappName"

The problem is that you cant here say
webapps/youbWebappName/Yourflexappname. This means that you need to put the
welcome index.html file at the root of the webapp, which flexbuilder will
not automatically do.

RE: [flexcoders] Fade from one color to another

[Deepa Subramaniam]

Ah - that is because AnimateProperty is just cycling through all the RGB
values between your fromValue color and your endValue color. What you
may want to do is add an event handler for the tweenUpdate event on the
AnimateProperty effect instance and check to see what the value passed
in the TweenEvent object is. That value is what the backgroundColor is
at that moment in the lifetime of the effect. You can then add in your
own logic that sets the backgroundColor depending on where the effect is
in its lifetime (ie: simulate a progression from dark gray to light
gray). I'm not 100% sure how that will work out but I'd be interested in
finding out what doesn't work about it.

 

Incidentally, you should check out Alex Uhlmann's Animation Package
where I think he has an effect that does exactly what you want. That
will probably be easier :-)

RE: [flexcoders] Adding Labels to the PlotSeries

[Ely Greenfield]

 
 
Hi Denis.  No, the default series types don't support labels by default.
You have a couple of choices:
 
1) write a custom item renderer, that adds a label next to each point.
This shouldn't be too difficult, but you won't have any guarantee that
an automatically generated axis range will be large enough to show the
labels.
 
2) write a custom series/ extension to the plot series.  This will solve
the problem of #1, but requires a bigger investment in learning how the
charts work.
 
3) use the prototype code I just posted
(http://www.quietlyscheming.com/blog/2006/12/04/some-thoughts-and-exampl
es-on-making-custom-flex-charts-simpler/) to 'draw' a label next to each
data point. There's a sample at that link that does exactly that, with a
column series. It would be trivial to adapt that to work with a
PlotSeries.  This is the easiest approach, but least performant.
depending on how much data you're trying to show, it might suit your
needs perfectly. Try it out.
 
Ely.

Feature requests can go to http://www.adobe.com/go/wish.

 

If you know the name of the event generated for [Bindable] you can
simply put multiple bindable statements on the fullName property:

 

[Bindable(event="firstNameChanged")]

[Bindable(event="lastNameChanged")]

Public function get fullName():String {...

 

I don't remember if we document what the event naming pattern will be.

Hi Adobe Team,

 

Is this the right forum to talk about Flex Builder features? I have
often found myself in situations where it would be very handy to say
something like this.

 

[Bindable] public var firstName:String;

[Bindable] public var lastName:String;

 

[Bindable(basedOn='firstName,lastName')]

public function get fullName ():String {

return firstName + ' ' + lastName;

}

 

The idea being that when a binding for firstName or lastName changes,
the dependant binding fullName will also get fired. The only way I know
to do this with the current tools is:

 

private var _firstName:String;

private var _lastName:String;

 

[Bindable] public function get firstName():String {

return _firstName;

}

 

public function set firstName(str:String):void {

_firstName = str;

dispatchEvent(new PropertyChangeEvent('fullNameChanged');

}

 

[Bindable] public function get lastName():String {

return _lastName;

}

 

public function set lastName(str:String):void {

_lastName = str;

dispatchEvent(new PropertyChangeEvent('fullNameChanged');

}

 

[Bindable(event='fullNameChanged')]

public function get fullName ():String {

return firstName + ' ' + lastName;

}

 

Which is obviously less expressive. It would be great to have a kind of
'based on' meta-data for bindings as in my example. Or is there a way to
do this already that I don't know about?

[flexcoders] Re: Mercury QT Pro - LoaderRunner + Flex

[coderjun]

Lance,

>From what I've heard through the grapevine, you can request the Quick
Test Pro Flex plugin from Adobe.  However I'm not exactly sure who to
contact for it. Maybe someone else in the group has this info or has
received the plugin before?

In regard to LoadRunner and AMF3 support, I have been working with a
client that had this same question.  Basically, the answer from Mercury
tech support was that AMF3 encoding was not supported and the workaround
was for them to  downgrade to the AMF0 encoding...which of course is not
an option if your using AMF3-only supported features:

"AMF3 supports sending int and uint  objects as integers and supports
data types that are available only in ActionScript 3.0, such as
ByteArray, XML, and IExternalizable."*

* Taken from:
http://livedocs.macromedia.com/labs/as3preview/langref/flash/net/ObjectE\
ncoding.html

Here's a link if you decide to go the AMF0 route:
http://livedocs.macromedia.com/flex/2/docs/wwhelp/wwhimpl/common/html/ww\
help.htm?context=LiveDocs_Parts&file=1105.html

Also, you can run "AMF" and "object encoding" searches on the Flex 2
livedocs site for more info.

Hope that helps some,

RE: [flexcoders] Fade from one color to another

[Dustin Mercer]

Dorkie, I had done something like this before and I used a fade effect
in combination with the Color change.  Try this and let me know if this
is what you want to see...  It has one problem, it fades the children as
well, but I had gotten around that, I just don't remember exactly how.
I'll dig up the code :-)  Let me know if this is what you wanted to
achieve first.  Also, using an animateProperty to change the background
color of the application in this example is overkill.  I would be much
more efficient to set the style with actionscript in the effectEnd event
on the first alpha fade (or something similar)...

 

Note , this == Application.  I used it on the creationCompleteEffect of
the Application.

[flexcoders] Using Assembler fill approach, an added item comes in as sequence of ADD, UPDATE, REPLACE

[Brian Weisenthal]

We are using the java assembler to fill collections. Sometimes an add  
comes in as a CollectionEvent.ADD with items[0] being the fully  
populated new item. This is good. Then some other times, the item  
comes in as a sequence of ADD, UPDATE, and REPLACE events. The ADD is  
basically a null object, the UPDATE sets the uid, then the REPLACE  
replaces with the fully populated object.

I think this is related to having the item pending at the point of  
addition but am not sure why or if this is something that can be  
avoided. Anyone see this behavior before?

RE: [flexcoders] FDS Environment Challenge Questions!

[Jeff Vroom]

Comments inline:


1) Without using Peter's FDS Plugin, what is the easiest way to deploy
a FDS-enabled project as http://localhost:8080/ 
or
http://localhost:8080/ProjectName/?
  Every example I've been able to
find has it coming out of the flex.war as
http://localhost:8080/Flex/ProjectName/
 



When you are deploying a web application (.war), you specify the
context-root in app-server specific configuration.  Most of them have a
way to specify a single "default web application", i.e. with a
context-root of "/".   For tomcat, this is in the server.xml file I
think.   If you build an "enterprise application archive" (.ear), you
specify the context-root in your application.xml file and so can do it
in a standard way.   The only other thing you need to be sure is that
you configure the context-root in your flex builder project properties
to be "/" and that the paths in any HTTP based endpoints are valid for
your context-root setting.

2) When deploying using FDS compile on server option, how can you
configure your server to acknowledge
http://localhost:8080/HelloWorld/Main.mxml
  when
http://localhost:8080/HelloWorld/ 
is accessed? Default .mxml
parameters? I'd figure to use the index.htm with presentation similar
to the template when using a non-FDS enabled version but unclear where
to point the embed items to.



You can specify "Main.mxml" in the welcome-file-list attribute in your
web.xml file - something like:

Main.mxml

I think it goes right after the servlet-mapping tag.  


3) FDS Plugin Specific - How *should* one break down their content
w.r.t the directory structure provided? I was able to create a simple
sample (one event class, one valueobject, two component .mxml views
called from the Main.mxml. The only way I was able to get any to work
was with everything nested within sub-directories of the WebContent
folder. I'd expect I could use the [source_path]user_classes for .swc
but it didn't seem to play nice with pure .as files.

I am not sure I fully understand this question but the source path ought
to work as long as you put your source files in a directory relative to
the package used by that class.  For example, if you put your classes in
a package called "foo", your source path should contain a directory
called "foo" which should contain the classes in the "foo" package. 


4) Same question as #3 but expand your example answer for a
Cairngorm-ified project.



I don't think Cairngorm will affect this.


5) How to turn all this into a deployable .war or .ear file on a
non-development machine? This is more a general java question but
figured I'd press my luck like that old tv show and make it a 5 pack
o' questions.



There is no real trick to making a .war file other than building the
right directory structure with the files in the right locations and then
zip them up (or use java's "jar" utility).  Note though that there are
special steps you'll need to follow if you want to deploy an FDS based
application as an unexploded .war file.  Specifically this means
disabling the web tier compiler as that requires access to the mxml
files as files, not as entries in as a zip file.

Tracy:
 
I realise that the XML class is a dom, but that doesn't allow me to have TYPED 
entities, does it? Also with classes I can include validation code, etc. in the 
getters/setters.
I can't do this with the XML class, can I?
 
---
 
Lachlan:
 
Yes, I am trying to unmarshal the XML into custom classes as you say.
A bit of background wouldn't hurt ...
 
The XML describes a "document" where each line is EITHER some text, OR (up to 
3) graphics, OR a barcode, or a couple of other entities.
It's all XML, nodes and attributes, but not very regular.
 
A line/node could look like:
 
Name: 
 
OR
 

vicdpi.jpg
sunset.jpg

 
OR
 

 
So that each line needs a different customItemRenderer. Since the document is 
discretely line-based in structure, I thought a 1-column datagrid suited it 
well.
I tried dynamically rendering elements (in form structures) thru AS, but that 
proved to be pretty messy ... I could go back to it, but I'd rather not.
 
Yeah, I figured ICollectionView but I'm not actually sure how to assign it ... 
I've discovered Aral Balkan's notes on "Designing Data Models", that might 
clear it up for me.

Hi John,



Sorry if I missed the point but I'm not entirely clear on what you're trying to 
do here. Do you want to unmarshal your XML into an object graph of custom 
classes? I don't understand how the multiple renderers comes into it. What is 
the XML describing? Is it a result set or something less regular?



With regard to point 2, I think anything can be a dataProvider if it implements 
one of the accepted interfaces. IList, ICollectionView etc.

Each row of the datagrid uses a (state-based) customItemRenderer [don't get me 
started on the problems I've had with ViewStack-based approach].

Anyway, it seems to work fairly well ... but I've now been asked to take a 
slightly different approach. The XML needs to be shoved into an Object Model (a 
custom DOM), so that the same data can have multiple renderers/converters 
created in the future (not just "renderToScreen")... renderToPDF, renderToCSV, 
etc. Now there are notes in the PDF docs on creating a Class-based model ... I 
figure I'm gonna create an array of Objects, each one typed as they need to be, 
you know Bool, Text, Graphics, customSetOfAttribs, whatever ... custom addItem 
and removeItem functions which use templates for each Object type.

1. Any comments on my methodology?

2. How do I assign an ActionScript class as a dataprovider (for a datagrid)?

Thanks.

Cheers
John

Re: [flexcoders] FLV Duration

[John Kirby]

Via onMetaData you should be able to get duration.  Have you tried 
something like this?


private function playStream():void {
  
 
   stream = new NetStream(nc);
  
   stopTimer();
  
  videoHolder = new UIComponent();

  videoHolder.setActualSize(defaultWidth, defaultHeight);
  video = new Video(defaultWidth, defaultHeight);
 
  video.attachNetStream(stream);
 
  stream.play(streamVideoURL);
 
   stream.addEventListener(NetStatusEvent.NET_STATUS, 
streamStatusHandler);

   var client:Object = new Object();
   client.onMetaData = onMetaData;
 
   stream.client = client
  
   }
  
   public function onMetaData(info:Object):void {

   duration = info.duration;
   fRate = info.framerate;
   totalBytes = info.bytesTotal;
   metaWidth = info.width;
   metaHeight = info.height;
}

john_69_11 said the following:


Is there an easy way to figure out the duration of an FLV thati s
being played? I have been looking at the NetStream object and the
onMetaData event, but it seems like the FLV does not always have the
metadata set. The FLVs I want to play are created my other people, so
there is no way to force them to add the metadata. is there any way
to easily get around this?

RE: [flexcoders] Re: Cartesian Charts colum styling different from other chart types

[Ely Greenfield]

That approach will assign  a drop shadow filter to each item renderer.
Sometimes that's the effect you want, and sometimes you want a drop
shadow assigned to _all_ the renderers at once. In that case, you can
assign a dropShadow to the 'filters' property of the columnSeries.

[flexcoders] TitleWindow Component...help!

[qnotemedia]

OK - so I'm using the generic TileWindow example found on the 
Component Explorer.  It basically shows you how to build something 
where:
1) User clicks a button, Window pops up.
2) User types into a text box in the window, clicks Submit.
3) Text typed in appears in the main app.

http://examples.adobe.com/flex2/inproduct/sdk/explorer/explorer.html

But, I'm having a little difficulty understanding the assignment of 
the returned data.  i.e.:

login.loginName=returnedName;

...where login is the instance of the TitleWindow, loginName is a 
public Text variable inside the component, and returnedName is a text 
box in the main app.

My confusion comes up when I try to edit this so that:
1) App has a combobox.  Dataprovider for the combobox is an 
ArrayCollection of data: "data" and "label."  User clicks a button, 
TitleWindow pops up.
2) User types into a text box in the window, clicks Submit.
3) The text is a passed as a label, along with a generated ID 
(generated in the component) and is added to the combobox's 
dataprovider.

The problem appears to be that there is no handler of the Submit 
button click on the main application.  Obviously, I would add to a 
datasource and return an ID from that, but I can't even get this to 
work manually (i.e. for testing purposes, setting a static data and 
label).

Just trying to keep this as simple as possible.  Seems to me that if 
I can pass a string of text, I should also be able to pass an Object 
that is added to a dataProvider in the main app?  Right?

Help!

This is, in my opnion, an incredible error in design that I would hope
that they fix. When building on your development environment, as
opposed to on the server, there is no way to get it to automatically
put the index.html and your swf at the root of your webapp. It will
always be at webappname/flexappname a.k.a  localhost:8080/flexappname.
What I actually do when I am deploying to my server is to copy all the
files from webappname/flexappname to the webappname directory. Its
ugly but several others on the list have said that they have
encountered the same problem and there is no good solution. I *have*
heard that it is possible to do this if you compile on the server, but
since I was never interested in this I have no idea if this is true.

I have been able to use the source path thing but at this point all of
my code is in my project so I cant tell you if there are any tricks to
getting it to work because I cant remember. But at least I can tell
you that it does work.

I dont quite understand this question because the cairngorm directory
structure is pretty clear. Are you asking how you store your cairngorm
files outside what you called your webContent folder? If that is the
question, I would not suggest it. One thing I do though, to modularize
my work is that my project is made up of a collection of smaller
cairngorm based projects that link to one another. The only issue is
that the services.mxml cant be shared. But this allows me to look at
small nuggets of my app rather than a huge common structure. It also
allows me to create swc's that can be shared with other projects. For
example I have created a login system that I can drop into other apps
fairly easily.

I dont use WTP because it just seemed to complicated. I didnt want to
spend the more than a day I guessed it would take to figure out how to
work throught the horrendous documentation. As a result I use the
sysdeo tomcat plugin which works like a charm. I right click on my
project and say "build war" and it does it. I would imagine WTP has
something like this but it was just so ugly I couldnt bear it. But in
any case a WAR is nothing more than a compressed (zip?) of the webapp
directory structure with your app in it. So it shouldnt be too hard to
get that from eclipse to deployment. But if you are committed to WTP I
am sure (hope?) there is some option for this.

[flexcoders] Cartesian Charts colum styling different from other chart types

  I am using different chart types on my app. Some are column charts,

[flexcoders] FDS Environment Challenge Questions!

[Jamie O]

Hello,

After a laborious day of uninstalling, re-installing, washing,
rinsing, repeating, I finally have my eclipse environment setup with
WTP, Java 1.5 and the FDS Plugin Project Peter Martin created. The
directory structure seems to make more sense to me, but have raised a
couple of questions in my brain - some of which are general Flex /
FDS, others are specific to WTP / Tomcat implementation:

1) Without using Peter's FDS Plugin, what is the easiest way to deploy
a FDS-enabled project as http://localhost:8080/ or
http://localhost:8080/ProjectName/? Every example I've been able to
find has it coming out of the flex.war as
http://localhost:8080/Flex/ProjectName/


2) When deploying using FDS compile on server option, how can you
configure your server to acknowledge
http://localhost:8080/HelloWorld/Main.mxml when
http://localhost:8080/HelloWorld/ is accessed? Default .mxml
parameters? I'd figure to use the index.htm with presentation similar
to the template when using a non-FDS enabled version but unclear where
to point the embed items to.


3) FDS Plugin Specific - How *should* one break down their content
w.r.t the directory structure provided? I was able to create a simple
sample (one event class, one valueobject, two component .mxml views
called from the Main.mxml. The only way I was able to get any to work
was with everything nested within sub-directories of the WebContent
folder. I'd expect I could use the [source_path]user_classes for .swc
but it didn't seem to play nice with pure .as files.

4) Same question as #3 but expand your example answer for a
Cairngorm-ified project.

5) How to turn all this into a deployable .war or .ear file on a

  Hi Ralph,

I know this thread is slightly old, but I have been debugging some
garbage collection issues in an app I'm working on right now. I
noticed you said the following when responding to Bjorn:

"You'll have to remove all references to a specfic object to
actually have it removed. We've run into some problems with this;
this was related to states, though, and this is also something which
is by design."

Right now I'm noticing some jumps in memory consumption when
switching between one view state of a component and another. Do you
mind giving a quick tip on what you discovered about garbage
collection and states in your debugging?

Thanks,

[flexcoders] FLV Duration

[john_69_11]

Is there an easy way to figure out the duration of an FLV thati s
being played?  I have been looking at the NetStream object and the
onMetaData event, but it seems like the FLV does not always have the
metadata set.  The FLVs I want to play are created my other people, so
there is no way to force them to add the metadata.  is there any way
to easily get around this?

Hi John,

 

Sorry if I missed the point but I'm not entirely clear on what you're

With regard to point 2, I think anything can be a dataProvider if it

RE: [flexcoders] Re: Styling in Flex is officially ridiculous

[Lance Linder]

Maybe I am wrong but I thought that you can no longer to something like
this:

 

flash.text.TextField.prototype.styleSheet = myStyleSheet;

 

In my tests this doesn't create a compiler error but it doesn't work
either. If I am wrong someone please shed some light on this because I
haven't been able to make it work as it did in AS1/AS2.

 

Thanks!

I guess what really made this easier for us in the past was the
ability to use the 'prototype' chain to override properties and
functions at a global level for all TextField instances. I know
overriding the prototype chain is a thing of the past and for good
reasons but it sure would be nice if ALL textFields in every component
could get a StyleSheet instance from the StyleManager.








I can be wrong, but "prototype" is still "functional", am I wrong?

[flexcoders] cornerRadius and datagrid

[jnewport]

Wondering if anyone else has this issue or if its a bug or if flex
isn't capable?

I am trying to set the the attribute cornerRadius="8" for a dataGrid,
but it appear the a top layer follows the attribute, but a bottom
layer still has pointed corners. So you end up with these pointed
corners sticking out of rounded corners.

Am I missing something?

[flexcoders] Re: DataGrid horizontalScrollPosition and scrollbar out of sync

[coderjun]

Igor,

Thanks for the reply.  I tried responding back on Friday and I was 
having severe issues connecting with yahoo groups.

I appreciate your insight, that is currently what I am doing to 
resolve the issue in the app I am working on.  I was just severly 
bummed when I found out that setting the horizontalScrollPosition 
manually would jack up the state of the scrollbar.

I guess the other workaround would be to fire a manual scroll event 
to get the player to redraw the DataGrid...resulting in the sync of 
the left-most column (horizontalScrollPosition=2) in the view and 
the scrollbar.

Anyone on the Flexcoders group know of a fix that doesn't require a 
hack workaround? :)

Anyway, thanks again Igor!

[flexcoders] Cairngorm’s Anaemic Domain Model

[Lachlan Cotter]

Apologies if this shows up twice, I posted it earlier but apparently  
it was lost.

Something that troubles me about the Cairngorm architecture is the  
apparent lack of any proper domain model. Although it is argued that  
the domain model actually exists on the server and that the Flex  
client is essentially a view, I have always found it necessary to  
construct some kind of object graph of the domain on the client as well.

I have two concerns regarding this.

First, I have never seen examples or discussion of Cairngorm that  
deals with this issue. In most cases the 'model' isn't much more than  
a collection of dumb value objects without complex relationships.

Second, and more importantly, pretty much all the logic of Cairngorm  
apps seems to reside in the Command and Delegate classes with not  
much to speak about in the actual model. It seems to be the Commands  
that end up manipulating the application data directly, and I'm a  
little uncomfortable with this.

I think Cairngorm’s a good method for managing code and iterative  
development, but I'm not sure about how well it does encapsulation  
and MVC.

Anyone care to discuss?

Cheers,
Lach

RE: [flexcoders] Re: flv playback

Hi John,

 

Sorry I see you got the same answer I gave ya at the conference. Had another 
idea but no clue if it'd work ...loading the flv into a movieclip. (movieclip 
has methods for jumping frames) Somehow I don't think the movieclip frames 
correlate to the flv itself but maybe it'll spark an idea from someone else 
more familiar video.

 

Cheers,

Stace

 

import flash.display.MovieClip;

import flash.net.*;

import flash.media.Video;

 

public class VideoTest extends MovieClip

{

private var videoUrl:String = "http://example.com/test.flv";;



public function VideoTest()

{

var connection:NetConnection = new NetConnection();

connection.connect(null);



var stream:NetStream = new NetStream(connection);



var myVideo:Video = new Video(360, 240);

myVideo.attachNetStream(stream);

stream.play(videoUrl);



addChild(myVideo);

}

One of the problems is that I cannot modify the existing flv that I
want to play. You mentioned key frames in this post, I was looking at
the video and netstream objects and I can use those to play an flv,
but they do not seem to have methods to navigate to a specific frame
either. Looking at it again today I noticed the seek method which
says it goes to key frames, are these just the normal frames in a
movie or do you have set those when the video is encoded? Any other
ideas would be welcome

[flexcoders] Mercury QT Pro - LoaderRunner + Flex

[Lance Linder]

Anyone using or had success with trying Quick Test Pro with Flex? This
was something I wanted to evaluate ever since Macromedia/Adobe announced
they were working with Mercury back in October of 2005. Since the beta
release of Flex I really haven't heard anything more about this other
than some info that there might be better support between the two once
Flex 2.1 is released. Can anyone comment on this that has tried to use
Quick Test Pro with Flex 2.0?

 

Also I really really need a good load testing tool and LoadRunner looks
like the ticket especially since I am already interested in Quick Test
Pro. Has anyone used LoadRunner with AMF3 or does LoadRunner even work
with AMF3? Right now I am not so concerned about RTMP but AMF3 is a
must. It seems that SilkTest from Borland supports AMF3 but I would
rather stick with a vendor that has both functional GUI test tools and
load test tools that meet my requirements.

 

Thanks!

I need to fade my application background color from 0xC47D31 to 0x67DEF9
and I have no idea where to start. I've seen AS2 actionscript around
that I can try to convert but what I'm looking for is a already built

[flexcoders] Re: Sand Box Security Error

[drome.dario]

Kumar,
This is a security violation of a basic Flex rule: "you can not 
access to url coming from other domains than those where the swf 
comes from"
That is, your swf comes from "localhost" and you are trying to access 
to "rss.news.yahoo.com"... this is not allowed by default.

You would have to put your swf or a cross-domain file 
under "rss.news.yahoo.com". Most of the time you can not perform none 
of above things and, in that case, you will need a "proxy" on your 
own backend server that access directly to "rss.news.yahoo.com".

I think that FDS 2.0 has such kind of http proxy.

Hope this helps
Regards

[flexcoders] Re: Viewstack.removeChildAt() and Garbage Collection

[coderjun]

Hi Ralph,

I know this thread is slightly old, but I have been debugging some 
garbage collection issues in an app I'm working on right now.  I 
noticed you said the following when responding to Bjorn:

"You'll have to remove all references to a specfic object to 
actually have it removed. We've run into some problems with this; 
this was related to states, though, and this is also something which 
is by design."

Right now I'm noticing some jumps in memory consumption when 
switching between one view state of a component and another.  Do you 
mind giving a quick tip on what you discovered about garbage 
collection and states in your debugging?

Thanks,
Jun

RE: [flexcoders] XMLList/XMLListCollection: sort on attributes

[Deepa Subramaniam]

Assuming the XMLListCollection created from the myData XML object looks
like this:

public var col:XMLListCollection = new
XMLListCollection(myData.children());

Then you would sort on the category name like so:

private function applyMySort():void
{
var s:Sort = new Sort();
s.fields = [new SortField("@name")];
col.sort = s;
col.refresh();
}

As for your second question, we don't support e4x expressions in the
sort field. To get that behavior you'll have to write your own
compareFunction that compares on the values you desire. You'll find that
the mx.utils.ObjectUtil class has all the comparators you'd need to do
this. 

Cheers,
deepa

[flexcoders] Focus in text fields

[dchilcoat]

I have a data grid for which I want to be able to focus on the entire 
text in a field in the grid so the field can be changed by simply 
typing over what is already there.  Currently, when I focus into the 
field, the cursor goes to the end of the text instead of hi-liting all 
the text in the field.  For example, when I use the mouse to select a 
field with text 'ABC' in it, the cursor ends up after the 'C'.  The 
cell has a cell-renderer which is probably complicating the issue.  Is 
there code I can put in the cell-renderer that will result in the 
action I want?  I noticed that cells that do not have cell-renderers 
seem to work correctly.

One of the problems is that I cannot modify the existing flv that I

but they do not seem to have methods to navigate to a specific frame

Depending on the complexity of the ComboBox dataProvider, you could

Re: [flexcoders] Re: Styling in Flex is officially ridiculous

[Derek Vadneau]

You can't extend things like TextField or Object like you could in AS1/AS2,
which was Lance's point. I think that's a different discussion.

I can see Ben's point about Buttons and borders.

When I start a MXML project and drop a button on the stage I can change the
border colour of a button, along with other properties. Why is it so odd
that I would assume that I should be able to disable the border? If the
border isn't actually a border, then why provide a styling options as if
there was a border? That's the flaw.

If you are creating a component that has the look of a border, allows the
user to change the colour of the border, why wouldn't you allow the user to
disable the border? Change the width of the border? Why would the component
support some (relevant) styles and not others?



I can be wrong, but "prototype" is still "functional", am I wrong?

RE: [flexcoders] FDS on the desktop?

[Peter Farland]

SWFs by default can either choose to access the file system or the
remote network (e.g. requests made for data via HTTP), but not both.
Flex compilers produce swfs that elect to use the network by default.
 
Apart from that, there's no reason why you can't run a SWF from the
desktop (the .mxml -> .swf conversion via FDS Webtier compiler is a
development time convenience).
 
Some things to consider though... if you're using Flex Builder or the
mxml command line compiler you'll probably need to provide the command
line argument -services to point to the
/WEB-INF/flex/services-config.xml file so that it can compile in the
channel definitions for you (assuming you are not creating your own
ChannelSets programmatically or you are using the DataService API).
Also, you will need to edit each relevant channel-definition endpoint
defined in services-config.xml file so that a fully qualified URL is
defined - i.e. you can't rely on the {server.name}, {server.port} or
{context.root} tokens for portability.

undefined property prop through a reference with static type Function."

Global.as defines Function as dynamic yet FB produces an error.

If you try this example:

you'll get compiler errors.

Is there a way to add properties to a function or has this been removed in

Re: [flexcoders] Best practices for displaying large texts

[Daniel Freiman]

Justify Full will work in flash if the text is static.  However you normally
do this through the flash IDE, so while it must be possible in Flex, but I
don't know how.  Otherwise, Text or TextArea should be fine.

  Hi Pablo,

I'm not sure this is the best answer to your question but as far as I know
the Text component is the right choice for displaying multi-line,
non-editable text. If you want your users to be able to edit the text, you
can use a TextArea instead.

I'm don't know of a way to do justified text in Flex. Sorry.

Re: [flexcoders] explorer local file

[Daniel Freiman]

Nope.  File ref is it.  This is for security reasons.  Your only other
option is write/use an applet or activeX that can access the file system and
use javascript to communicate between the flash and the applet.  (I've never
tried this, but it should work.)

[flexcoders] Chart dragging help

[Dana Gutride]

Any ideas on how to drag the contents of a chart.  I think the example
here:  http://www.quietlyscheming.com/blog/charts/interactive-bubble-chartis
in the right direction. My needs are slightly different, though, and
I'm
unsure of how to proceed.  The data covers 24 hours, I've added a linkbar up
top and I'd like to show 3, 6, 12 or 24 hours at once but allow the user to
pan left or right through the rest of the data for that day.  Any ideas on
how to set the min/max for the data displayed?  Also how should I change the
chart so the user can't drag beyond 12:00 p.m. or 1:00 A.M (effectively
showing only one day's worth of data)?

RE: [flexcoders] Simple Question - Array to ArrayCollection - Best Practice/CFusion

[Peter Farland]

It depends on what Java type ColdFusion returns to FDS for
serialization. By default, FDS returns java.util.Collection
implementations as mx.collections.ArrayCollection, and native Java
Arrays (i.e Object[]) as ActionScript Arrays. So, if your seeing that
event.result can be successfully coerced into an ArrayCollection, this
would imply that ColdFusion is returing a java.util.Collection
implementation to FDS. Other comments on this thread are correct, you
can't cast/coerce a complex type to another complex type unless it
really is an instance of that complex type (i.e. you can't coerce and
Array to an ArrayCollection... ArrayCollection "has an Array", not "is
an Array").

Hi people,
I am using flex 2..i m creating an application using Drag n Drop
Manager.I have a main Application which has a small library kind of
module similar to Flash Library.This library will contain all the
images in it..Now what i want is to drag images from that library and

that dropped object.
 How to go for this..Can anyone help me out with this..

Re: [flexcoders] Re: Styling in Flex is officially ridiculous

[Rogerio Gonzalez]

I guess what really made this easier for us in the past was the ability to
use the 'prototype' chain to override properties and functions at a global
level for all TextField instances. I know overriding the prototype chain is
a thing of the past and for good reasons but it sure would be nice if ALL
textFields in every component could get a StyleSheet instance from the
StyleManager.









I can be wrong, but "prototype" is still "functional", am I wrong?

Re: [flexcoders] Re: strange CheckBox behavior (as an item renderer in pop up)

[Roman Protsiuk]

Hi.

It should if I set dataProvider once and then just work with it using for
example addItem(...), removeItemAt(...), refresh(), etc.
But what if I set brand new dataProvider to List every time it is popped up.
However, even if i'd set dataProvider once and then just modified instances
of data in it like

for (var index : Number = 0; index < _popUp.dataProvider.length; index++) {
   _popUp.dataProvider[index] = false;
}

or in another way described effect remains the same.

At the moment the only obvious workaround is to
PopUpManager.createPopUpevery time instead of using existing one
through
PopUpManager.addPopUp.
But the solution and the reasons for this behavior still unclear.

[flexcoders] FileReference.download() crashes the browser

[Benoit Hediard]

Hi,
 
We have many users reporting browser crashes when trying to download files
from our Flex2 app.
But we have never been able to reproduce the problem.
 
Apparently, they have the latest Flash Player 9 and the problem occurs on IE
(6 or 7) or Firefox (1.5 o 2.0), on Windows XP SP2.
So I suppose this is linked to some additional software installed on their
machine, may be Norton Internet Security 2005 (I have NIS2006 and cannot
reproduce the pb...).
We are currently trying to get more info on their config.
 
Anyone has encounter a similar issue?

RE: [flexcoders] flv playback

Hi John,

You could use CuePoints for this purpose. Encode your video with navigation
cuepoints (which sit on keyframes) and you can read out the CuePoints after
the FLV is loaded.

RE: [flexcoders] Simple Question - Array to ArrayCollection - Best Practice/CFusion

[Emile Swain]

HI

I've just checked my cf tests and I've found that I've consistently cast
the data in the result method called when I've received the result from
cf.

 

public function getMasterQuery_Result(event:ResultEvent):void

{

projectList.dataProvider = event.result as ArrayCollection

}

 

Where projectList is my datagrid. Of course this could quite easily be
model.workplace.employees where employees is typed as an ArrayCollection

 

 

All of my tests have been based on examples off the adobe site, so I can
only really assume this is the way to do it.

Subject: [flexcoders] Simple Question - Array to ArrayCollection - Best
Practice/CFusion

 

Hi all,

This is a best practice question really.

I use Cairngorm for the larger apps I build. I also use Coldfusion and
the nifty class mapping that it can perform between DTOs (or VOs,
whatever you call them)

Here's the conundrum. A lot of my top level classes have
ArrayCollections of other supporting classes.

For example: Workplace class has a collection called Employees, which
very possibly could have its own set of collections called Vehicles,
all custom VO classes.

So, when i get them back from Coldfusion and they come in as an Array,
I know that in order to use them as a dataProvider, you need to cast
them as ArrayCollection.

So far, so good.

But if I just do this: {model.workplace.employees as ArrayCollection}
in the dataProvider property, sometimes I receive coercion errors if
the returning array is one element.

Bottom Line: In a Cairngorm app, where is the best place to do my
casting or conversion of arrays??

RE: [flexcoders] Re: Drag/Drop - Datagrid. Target is off?

[Steve Cox]

There's a bug in Flex where the application uses an
ApplicationControlBar (possibly other controls, I'm not sure) which
causes the hitarea to be inaccurate.

Several people have also come across this (myself included) however no
work-around has been offered. I'm strongly hoping this will be in the
bug fixes at the start of 07.

I just now had a chance to try that out. That doesn't solve the
