[flexcoders] String Data Type Maximum Size
What is the maximum size of the String data type? Thanks, JB
Re: [flexcoders] Re: Rich Text Editor
And let's not forget that we need a way in Flex to work with simple HTML content that does not use Flash's antiquated set of HTML formatting. We already know the challenges of implementing a full browser in Flash/Flex (at least outside of AIR.) At least allow us to represent and edit simple HTML content that's compatible with the rest of the browser world. Again, no full HTML implementation is needed, just something along an HTML editor like FCKEditor.

[flexcoders] Looking for an HTMLEditor Component
We are building a CMS in Flex and one of the biggest challenges at the moment is the fact that Flex (Flash) doesn't have good support for HTML tags. We are currently using the RichTextEditor component and convert the HTML output to valid HTML tags. However, this leaves us with some serious challenges. So, here is the question: Has anyone created a Flex HTML editor component they are willing to sell? I have looked at several solutions, including working with IFrames or div tags and using HTML components such as FCKEditor. None of them really fit the model we need, as they all have some significant drawbacks. Please note that this is for a component that allows WYSIWYG editing of HTML content, not just a component that displays HTML content. Thanks, Jurgen
[flexcoders] Re: Traverse List of All Children
Thanks, Adam. I should have added more details to my post.
The 'complexity' is introduced by the fact that I am having to find
all Validator components, which are not DisplayObjectContainers.
Using Object (implemented by each validator subclass) in the
recursive function does not work either, since it catches components
such as flash.display.Shape, which doesn't have any children.

[flexcoders] List Component: Working with Collapsed and Expanded ItemRenderer
I am experiencing something mildly strange with the List component when using a custom item renderer that has two states, a collapsed state and an expanded state. When I have one or more item renderers in the expanded state, the List component eventually will display the vertical scrollbar. Here is the strange part: When using the scrollbar to scroll through the list, the original expanded item renderers that would normally disappear with their expanded state from the visual range of the list get collapsed and new list items that have not been expanded do so in their place. As I am not forcing this behavior my thinking is that the List component is either missing a property setting to prevent this behavior, or this may be either a bug, or simply by design.

RE: [flexcoders] List Component: Working with Collapsed and Expanded ItemRenderer - Solution
I'm documenting this here for others who may be struggling with this:
It has been suggested to use a VBox and simply just add children to
it based on items in the dataprovider. That's a great approach and
would have been my workaround. However, Alex was giving enough
pointers to implement the solution based on storing the expanded and
collapsed state in the data object.
This can be easily done by overriding the data property of the item
renderer and using a 'collapsed' property to restore the state of the
item renderer.
So, here is an example:
override public function set data(value:Object):void {
super.data = value;
if (value.collapsed) {
currentState = Closed;
} else {
currentState = Open;
}
// Dispatch the dataChange event.
dispatchEvent(new FlexEvent(FlexEvent.DATA_CHANGE));
}
Use the following to switch the state:
private function switchOpenState():void {
if (currentState == Closed) {
currentState = Open;
data.collapsed = false;
} else {
currentState = Closed;
data.collapsed = true;
}
}
I'm working with states and transitions, but this can be used in
other ways as well. The other piece would be to use a function to
switch the collapsed state and then setting the data.collapsed
property. Changing the state causes a sequence of events that will
eventually evaluate the data.collapsed property of each item renderer
and restore it to its proper state should the user scroll through the
list or interact with it in any other way.
Hope this helps,
Jurgen

Re: [flexcoders] Dynamic Scaling of a Flex Application
Thanks Alex and Yaagoub. Both work well, with some minor issues to get around: ScaleX and ScaleY: We have to set some metrics and listen for the resize event to keep things dynamic enough. Without setting starting metrics we don't really know what we should scale to when we resize. stage.scaleMode: There seems to be some funky behavior as to the application container itself. It's a bit difficult to get exact results. For example, setting the width and height of a canvas to 100% will scale the canvas and all containing children to the top left quarter of the canvas, depending on the aspect ratio of the browser or standalone Flash Player. Other issues seem to have to do with how Flex calculates the scaled ratios in relationship to the application container size. Nothing that we can't address with a bit of RD, but as I said, it's a bit funky. Again, thanks to both of you!

Re: [flexcoders] Flex Builder 2.0.1: Change Browser for Debugging
Hey Mike, Thanks for the response! This is happening on Mac OS X with Flex Builder 2.0.1. The system's default browser is set to Firefox. For the Flex debugging I'd like to use Safari though. I've been running into some caching issues with Firefox that I have documented in another post, thus the reason to use Safari. Safari is at version 3.0.3. Firefox and Safari are installed in their default locations (Applications folder). I've done a little bit more testing with the External Web Browser settings in Preferences and it seems to me that Flex Builder is having difficulties locating the Safari browser instance and is defaulting to the system default browser for debugging, which in my case is Firefox. This, even though the help documentation starts up in Safari when the selection is set to use Safari as the external browser. So, the question then would be what to specify for the Location and Parameters settings in Edit External Web Browser when setting up the Safari entry. Jurgen Mike Morearty wrote: Hi Jurgen, Carlos was correct -- changing the value in Window Preferences General Web Browser is how you change what browser Flex Builder uses to debug. If that doesn't work for you, then something is going wrong, but I am not aware of any bugs in that area. There is no per-project setting that is in any way related to this. The only per-project setting is, what URL is used when launching; but this has no effect at all on our choice of which browser to use. Just curious: What operating system are you on? What is your system default browser, and what browser are you trying to force Flex Builder to use? Is there anything nonstandard about how you installed any of your browsers -- e.g. did you install Firefox into a nonstandard location, or anything like that? I can't really think of much that would be going wrong here, but with more info, I might be able to take a guess. - Mike Morearty Adobe Flex Builder team http://www.morearty.com/blog http://www.morearty.com/blog --- In flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com, Jurgen Beck [EMAIL PROTECTED] wrote: Thanks, but that doesn't seem to have an effect on the browser that the debugger uses.

[flexcoders] Flex Builder 2.0.1 and Firefox Cache Issues
This is happening on a Mac OSX environment: I'm discovering that from time to time the cache in Firefox causes the debugger in Flex Builder to behave abnormally. It seems that Firefox retrieves a copy of the debug output SWF from its internal cache rather than loading it fresh from the output folder. This behavior causes issues when a new debug build is being debugged and is most visible when breakpoints in Flex Builder all of a sudden state that there is no code at that location. I've run into this issue now a few times and most recently couldn't figure out why my code wasn't returning the correct data type for a service call. Turned out that the Flex debugger was working with an outdated (pulled from Firefox cache) version of the application and therefore was returning the wrong data type based on old code. Once the cache was cleared, everything operated normally and as expected. Has this problem been documented and other than not allowing Firefox to cache the content, has anyone found a resolution to this? Thanks, Jurgen

Re: [flexcoders] WebServices and ObjectProxy
Let's back up for a minute. What exactly are you returning from your web
service? If you are returning an object that can be mapped to a Flex
value object, then you would do that in the result handler of the remote
object in Flex. That is where you would be using the line specified.
Now, in a data grid you typically use an array collection or a normal
array as the dataprovider. That array or array collection would contain
a collection of the mapped VOs you are returning from your web service.
The key here is to properly map the returned data to your VO. You can
then reference the data field properly by going for the VO object element.
The question of what you are returning from the web service is
important. The format may look different based on the back-end
technology you are using (PHP, .NET, etc.)
We may need a bit more information on the environment you are running
this on.

[flexcoders] creationPolicy Issues?
I'm running into a strange problem with the Accordion container. Setting creationPolicy to 'all' on the Accordion container will not force the controls in all the views to be created. It behaves as if it is still set to the default (auto). Anyone run into the same problem? Jurgen
[flexcoders] Re: creationPolicy Issues? - Issue solved
Well, this goes into the category of 'Where does Flex create the project files?' quirks: Quick answer: The debugger was pointing to a location where Flex essentially wasn't building the latest compiles. Long answer: If you ever run into really strange issues where you are convinced that it should be working, but ti doesn't, check that the build path and the output folder URL point to the same location. Explanation: I'm running Flex on a Mac, but am working on a .NET based server end solution, so I have to essentially build the Flex app against the IIS server location on a network Win2003 drive. Problem with the Mac is that it doesn't play well with the Windows network (at least so far), so it always looses the shared drives when I put it to sleep. Waking it up and reconnecting the networked shares messes up Flex when the shared name all of a sudden changes (because the Mac assigns a different name to it dynamically). So, all this to say that creationPolicy works as expected and this is something external to Flex, but still the source of some frustration if you don't pay attention to it. Hope this helps someone else! :-) Jurgen Jurgen Beck wrote: I'm running into a strange problem with the Accordion container.

[flexcoders] Events in AS3 Classes

The interesting thing is that code assist picks it up, but it shows up with an altered signature: myClass.addEventListener(Event.MY_EVENT,myEventHandler); I wasn't able to find any documentation on it. So I am wondering if this would actually work. At the moment I'm not able to fully test it, as the compiler throws an error with my static class (defined as a singleton) stating: Error 1119: Access of possibly undefined property MY_EVENT through a reference with static type Class.

Re: {Disarmed} [flexcoders] Re: Events in AS3 Classes
I sent the response off a bit too quick. Here is more: I was actually positively surprised to see it show up. I am a big advocate of strong typing, as it make programming that much more straight forward and helps reduce bugs and errors. What I wish we would have in Flex/AS3 is a way to have simple 'custom' events (those that don't require additional objects or arguments packaged with it) to self-register through a new class.

Re: {Disarmed} [flexcoders] Just getting started, hitting walls...
Welcome to the community, Dave, good to have you! Essentially, the key to what you are trying to do is split up your application into individual modules.

Re: {Disarmed} Re: {Disarmed} [flexcoders] Just getting started, hitting walls...
Code is code. Not wanting to sound rude, but as with any other application that requires visual elements, you'll have to eventually create them somehow. The huge difference Flex makes is how you go about it. Essentially you will need to work with display containers, such as canvases, panels and the likes. However, Flex lets you break all this up into smaller pieces. Look for information on creating your own custom components, which sounds way harder than it actually is. On a higher level you can package components you have created (what you may call 'screens') and put them into separate modules. The key is to divide and conquer. Flex helps you quite a bit with it by using MXML components and modules. Jurgen Dave @ VitalPodcasts.com wrote: I feel like its back to the Old QBasic ways... Make one super long file that does everything, thats kind of nuts. You mean there isn't a Load NextScreen type of thing? Where a whole new set of objects live? and I don't have to worry about hiding everything? So far it feels to me, so far, I need to create lots canvases for the different screens the application uses, and then create a funciton that hides all but the one in focus... Can anyone describe how they setup their code? As far as logic, Im not too worried abotu that as most the logic will be in CF webservices, im more worried about having an insane amount of visual code in the MXML.
Re: {Disarmed} Re: {Disarmed} [flexcoders] Just getting started, hitting walls...
I'll address your first question: I'm doing this all the time. I'm working on my fourth huge Flex application. I've been developing enterprise type distributed applications for over 15 years and I can tell you that Flex is one of my favorite tools in terms of creating large RIA type apps. With Flex you now have the ability to bring to the web what previously has been mostly the domain of applications developed for the desktop/workstation world.

Re: {Disarmed} RE: {Disarmed} [flexcoders] SWF Size gets bigger (and bigger... but why??)
I'm on the Mac, so some of this you may to look and see what the Windows
equivalent is. But here are two things that you can do/use to make your
coding life easier:
Use the Command key (I think it's ALT in Windows) to hold down over a
definition (function call, class, property) and Flex Builder will
underline the word, which is an indication of a hyper link to the actual
definition of the class, function, or property. VERY handy to quickly
jump to your declarations.
The other would be to use the Outline window in Flex Builder, which
shows your properties and methods that you can jump to by
double-clicking on them.
Also, the Key Assist window shows the shortcuts in Flex Builder. You can
find it on the Help menu, or use the associated keyboard shortcut (the
Help menu should tell you what it is).
David Zuckerman did a presentation at 360Flex where he showed a number
of really useful tips and tricks. You can read up on it and view the
presentation here:

Re: {Disarmed} RE: {Disarmed} RE: [flexcoders] Flickr - Issue with LoaderContext
All true. Seeing that there really is no alternative other than using a
proxy server, I implemented a solution that seems to be working for this
specific application.
I ended up using at32.com ReverseProxy (http://www.at32.com), which is
for Windows. As long as the reverse proxy is bound to the IP address
that the Flex application is running on not even a crossdomain.xml is
needed.
Hope this helps someone else.

Roughly speaking:
AppDom/SecDom are for ActionScript code/classes.
crossdomain.xml allows you to import code/classes into the same
SecDom/AppDom so you can use the classes, otherwise you end up in a

All instances of things in a separate sandbox are off-limits, and
cannot access you either.
crossdomain.xml also allows you to access the display area of
displayobjects and image data because it effectively imports that
thing into your sandbox
AllowDomain permits code in another sandbox to touch things in your
sandbox
There is a security white paper on adobe.com that tries to explain
all of this. The idea is that you cannot use Flash as a screenscraper
of other flash content or image data w/o permission of the server
owner for both spoofing and server load reasons. And, of course, you
don't want to accidentally load bad code and have it steal stuff from you.
Flickr used to have crossdomain.xml files in the correct places, but
pulled them for some reason. I think if you google around you'll find
out why. So suddenly, they've made flash apps harder and proxy
servers are needed.

Re: {Disarmed} Re: {Disarmed} [flexcoders] Possible to send object to POST data?
No, neither AMFPHP nor WebORB require FDS, well, at least not the server technology. You have to set up the Flex project as an FDS project type and you may need to make sure that the FDS SDK is installed on your development box. However, the rest is handled by the server components (AMFPHP/WebORB for PHP). AMFPHP and WebORB each handle things a bit different. FDS goes beyond what either of them currently offer, with WebORB coming closer to the FDS feature set. WebORB for .NET is a different story and you should check it out too. However, that would be a .NET implementation. Mark Piller at Midnight Coders would need to chime in here, but I believe there are plans to expand WebORB for PHP quite a bit. So definitely keep that in mind. If you look at the feature set of WebORB for .NET, especially for the Enterprise version, there is a good chance that a number of them will end up in the PHP version too, at least that's what was stated by Mark in the past. If you require the full feature set of FDS now, you'll need to consider it instead.

Jurgen,
Thanks for the tip. I checked them out, but unfortunately, those
implementations don't address my main issue: getting the data from
the
server in a paged fashion. They simply allow you to view an
arraycollection in chunks, where Matt's goes back to the server as
needed to get chunks of the data.
With 150k records, I need the on demand paging.

Re: {Disarmed} RE: {Disarmed} [flexcoders] Data Paging a la Matt Chotin for Flex 2.1
Additionally, if you're doing this in .NET you could let your class
library handle the paging and simply just move the current recordset to
Flex as a List Of objects collection. All you would need to do then is
to tell your remote object where you are at in the list and if you are
resorting any of the columns. You should be able to do any resorting and
grabbing of sets of records completely on the .NET side.

passed through (which may mean subclassing LCV or writing your own

Aww, what about us non-FDS guys, Matt? :-( Protecting the FDS

unfortunately this app requires a .NET backend and doesn't have the

Re: {Disarmed} Re: {Disarmed} RE: {Disarmed} [flexcoders] Data Paging a la Matt Chotin for Flex
Flex in this case strictly acts as a pure presentation layer. In other
words, the data that is viewable in Flex is prepared and provided by the
.NET end. More specifically, it is a remote object with a set number of
records in the form of a list. Without the more powerful data mangement
features of FDS or WebORB .NET Enterprise, you'd have to handle a number
of things manually.
You'd have several facts to consider, for example, whether you allow the
user to sort or not. If that's the case you'd have to make sure that you
are keeping track of it on the server side too (which column you are
sorting on and from what record you are starting the sort, etc.)
Other factors include the data source you are dealing with. .NET has
some nifty ways of working with paged datasets, so the only thing that
you really need to concentrate on is the data pages you are feeding back
to the presentation layer.
No need to cache. For most part you are dealing with a disconnected
recordset of a limited set of records anyhow. It wouldn't make sense to
keep the 150k+ records in memory.
Instead what you would be doing is passing record pointers back and
forth between Flex and the remote object (class library object) so that
the class method knows where to start to get the next set of records.
It sounds way more complicated explaining it all. Again, concentrate on
using Flex purely to manage the limited number of objects (records) that
were passed on the last call and then pass the record id or whatever you
want to identify the starting point back to the class method to get you
the next set.
If you're doing this with WebORB it actually gets fairly easy to deal
with. Here is what your remote object declaration looks like in Flex:
private var service:RemoteObject = new
RemoteObject(GenericDestination);
public function getAlbums():void {
service.source = Services.dao.Album.AlbumDAO;
service.addEventListener(FaultEvent.FAULT,faultHandler);
service.GetAlbums.addEventListener(ResultEvent.RESULT,getAlbumsHandler);
service.GetAlbums(startID, numberOfRecordsToReturn);
}
Your DTO class in Flex would have a declaration such as the following:
[Bindable]
[RemoteClass(alias=Services.dao.Album.Album)]
public class AlbumInfo
{
static private var _instance:AlbumInfo;
public var ID:Number;
public var albumName:String;
public var artFullPath:String;
public var artThumbPath:String;
public var yearReleased:String;
public var itemName:String;
public var description:String;
public var storeDescription:String;
...
}
That's not the complete class, but you get the picture. The key is the
mapping of the remote class through the alias.
Here is the method on the server in your class library:
Namespace dao.Album
Public Class AlbumDAO
Private ConnectString As String
Private SqlConnection As SqlConnection
Public Function GetAlbums(byval startID as Integer, byval
numberOfRecordsToReturn as Integer) As List(Of Album)
Dim myDT As New DataTable
Dim myObjects As New List(Of Album)
' Build the list of Album objects based on what is returned
from the data store.
...
Again, it's not a complete class, but shows you what we are returning.
We return a list of Album objects, which Flex will then map properly to
the DTO class object.
Inside the GetAlbums function on the server you'd take the startID and
use it to get the next set of records, along with how many records to
return.
Hope this makes sense. It's not the only way to approach the issue and
you'd still have to work around some other issues such as getting the
total number of records in the table so you can set your paged navigation.
All Flex would be doing with this scenario is take the list of objects
(records) that are returned and put them into an ArrayCollection, which
you then can use as a DataProvider for a DataGrid or other component.
public function getAlbumsHandler(event:ResultEvent):void {
if (event.result.length 0) {
albums = new ArrayCollection(event.result as Array);
albums.filterFunction = albumsFilterFunc;
albums.refresh();
}
}
The above even includes a filter function, if you need it.

please forgive me for asking, could you clarify what's going on at the
.NET end and what the SWF would need to do to get the next page of data?
would the 150k+ records be held in a dataset (or whatever) in memory
(cache, session, etc) on the server? (flex would need to send a call
back for next N records to cursor thru them, I assume). A handle to
the cache would need to be sent too?
Re: {Disarmed} RE: [flexcoders] Re: Am I using the right technology?
Hi Mark, Seeing that you want to use ASP.NET, WebORB would be the way to go. It is pricey and Midnightcoders would make a killing if they would reduce the pricing for it as more firms would jump on the boat. I've been working with WebORB and must say that the tools that come with it beat everything else out there in terms of rapid application development. You get a fully implemented code generation module with it, which is irreplaceable. All that you really need to concentrate on is writing your class libraries in .NET and create the services and DTO objects on the Flex side and you're done. Can't get easier than that.

Re: {Disarmed} RE: [flexcoders] Re: Am I using the right technology?
I'll let Mark Piller chime in on the data management aspect. They've
implemented a FDS equivalent that is very nifty.
On the workflow:
To pull data from a data store, the flow goes like this:
Flex - WebORB - .NET Library - Data Store - .NET Library - WebORB
- Flex
WebORB serializes the data/object and maps the remote class so that by
the time the data arrives in Flex you have immediate access to the
object elements. For example, if I want to return the contents of a data
table that I pulled in my .NET class, I return it as a List Of object.
WebORB serializes the data/objects in the list so that I can build an
ArrayCollection with the results in Flex.
Here is what it looks like practically:
I have a service manager class in Flex that has a public method:
public function getShippingRateTable():void {
serviceStore.source =
Services.dao.ShippingRate.ShippingRateDAO;
serviceStore.addEventListener(FaultEvent.FAULT, faultHandler);
serviceStore.GetShippingRates.addEventListener(ResultEvent.RESULT,
getShippingRatesHandler);
serviceStore.GetShippingRates();
}
serviceStore is defined as a remote object:
private var serviceStore:RemoteObject = new
RemoteObject(GenericDestination);
The result handler looks as follows:
private function getShippingRatesHandler(event:ResultEvent):void {
if (event.result.length 0) {
shippingRateTable = new ArrayCollection(event.result as
Array);
}
}
My service manager class is defined as a singleton so that my returned
data is immediately available throughout the application.
The mapped Flex class for the ArrayCollection items is:
import mx.collections.ArrayCollection;
[Bindable]
[RemoteClass(alias=Services.dao.ShippingRate.ShippingRate)]
public class ShippingRateVO
{
static private var _instance:ShippingRateVO;
public var ID:int;
public var pounds:Number;
public var rate:Number;
public function ShippingRateVO() {};
}
On the server side, my .NET class ShippingRateDAO has a public method:
Public Function GetShippingRates() As List(Of ShippingRate)
...
Return rates
End Function
In it I am connecting to my data store, pull the data from a data table
and compile my list of objects into a List(Of ShippingRate), which I
then return.
That's all there is to it! WebORB does the rest.
About the examples:
I just checked on them and they were working fine. You may want to get
with Mark Piller if you continue to run into issues.
Mark also has a Yahoo newsgroup for WebORB that you can post questions to.

[flexcoders] ListCollectionView.addItemAt Bug?
It seems that there is a problem with the ListCollectionView class when
using it with an ArrayCollection. Using the addItemAt method produces an
index out of bounds error when an item is added with an index that is
beyond the length of the collection.
However, the Flex Reference states that:
If the list is shorter than the specified index, it will grow to
accommodate the new item.
Is this a confirmed bug, or am I overlooking something?
Here is some test code to check it out:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
creationComplete=initApp()
layout=vertical

collection.addItem(newObject);
newObject = new Object();
newObject.test1 = test3;
newObject.test2 = test4;
collection.addItemAt(newObject, 3);
}
]]

Jurgen
Re: {Disarmed} [flexcoders] ListCollectionView.addItemAt Bug?
Well, it looks like either the documentation is wrong, or the code. The
ListCollectionView class has the following method defined:
public function addItemAt(item:Object, index:int):void
{
if (index 0 || !list || index length)
throw new
RangeError(StringUtil.substitute(resourceOutOfBounds, index));
var listIndex:int = index;
//if we're sorted addItemAt is meaningless, just add to the end
if (localIndex sort)
{
listIndex = list.length;
}
list.addItemAt(item, listIndex);
}
Makes it very clear that the list isn't grown when the index exceeds the
length of the list. :-)
Anyone concur? If so, I'll submit a report to Adobe.

Would you care to share how you get those windows to show up on the second monitor? Thanks, Jurgen Paul J DeCoursey wrote: What are you talking about...

[flexcoders] Fade Effect on Labels
It seems that fade effects (fade in or fade out) do not fully work on labels, at least not the way I have implemented the fading. I have created MXML components containing labels that use embedded fonts configured through a style sheet. The fonts look fine, except that during a fade transition on the whole component, the labels maintain their visibility until the fade transition is fully done and then just simply disappear. The same font used in a TextArea component within the custom MXML component works as expected, so it has to be something related to labels controls. What would be the reason for that behavior and how can I get around it? Thanks, Jurgen
Re: {Disarmed} [flexcoders] Re: Fade Effect on Labels
Hi Brian, Well, that may be the reason indeed. That's where Flex is getting a bit funky. I've embedded the fonts into the application, but for some reason Flex is not taking them. I've had mixed results embedding system/native fonts in Flex. Some of them take fine, others won't. I'll dig a bit deeper and see what's going on with the fonts that won't show up properly... Thanks for the hint! Jurgen Brian Morearty wrote: Hi Jurgen, It seems that fade effects (fade in or fade out) do not fully work on labels, at least not the way I have implemented the fading. That's because you're using device fonts instead of embedded fonts. If you use native fonts, certain effects like fade and rotate do not work.

[flexcoders] Strange Error with Embed Statement
I've been working on this big project for the last 5 weeks and all of a
sudden today started getting errors on all my Embed statements in my
style sheet.
The following lines are an example of what Flex Builder now thinks are
invalid statements:
.trashButton
{
up-skin:Embed(source=/assets/ApplicationResources.swf#TrashCanClosed);
over-skin:Embed(source=/assets/ApplicationResources.swf#TrashCan);
disabled-skin:Embed(source=/assets/ApplicationResources.swf#TrashCanClosed);
down-skin:Embed(source=/assets/ApplicationResources.swf#TrashCan);
}
The resources are compiled into the application just fine, as they show
up in the application. However, the IDE sees these lines as errors and
will report them with:
Invalid Embed directive in stylesheet - can't resolve source
'Embed(source = /assets/ApplicationResources.swf#TrashCan)
I created a new test application with the same statement in it and
everything works as it should.
Cleaning the project won't resolve the issue.
Anyone run into this?
Thanks,
Jurgen

Re: {Disarmed} [flexcoders] Flex SWF running slow
Came up really snappy for me. No performance issues at all. You may need to check and see what else is going on with your Flash player and the browser you are testing this with. If you are running this on Windows, check with the Task Manager to see what processes are consuming a lot of CPU cycles. Running this on the Mac you can do the same with the Activity Monitor. This may start giving you a clue as to what may be happening on your system.

Re: {Disarmed} [flexcoders] Flex SWF running slow
Correction! On second and subsequent loads I could see what you exeperience. Here's what I first saw: When the application first loaded, I saw all the UI components on the form. Didn't take long to load the application. I then started playing around by clicking on checkboxes and noticed that you have the wait cursor enabled, indicating that you are communicating with AMFPHP. From that point on subsequent application loads (i.e. page refresh) would cause the delay you indicated. I haven't looked at your code, but I would start checking into what you are doing when the application communicates with the server. Are you loading any large datasets? Using AMFPHP you should be able to use the service browser to check how your classes return data. All this is of course stab in the dark, but I thought it was a bit strange that none of the delay issues started happening until after I had checked one of the checkboxes.

Re: {Disarmed} Re: {Disarmed} [flexcoders] Flex SWF running slow
Frame rate is still very much part of Flex, which by default uses 24 frames per second. You can change that during compile time. Here is a good write-up on frame rates: http://ajax.sys-con.com/read/303778.htm Question: Are the 300 plus UI elements the checkboxes, labels, etc.that you have in the application? They seem to be showing up almost right away, at least for the first tab. If you are writing your application code logically you can employ a lazy loading scheme whereby data is not loaded (including data binding) until it is really needed. Again, I haven't looked at your code, so I'm not sure how much data you are pulling in. One thing you could do is temporarily comment out any code that actually loads data and then see how your application behaves. If this eliminates the delay, you can start enabling the data loading mechanism one by one to see where the delay is introduced. Jurgen alex steel wrote: thank for looking It happens to me without any interaction I know for service browser and everything is ok, I still think it have problem with adding 300 ui elements with my flash experience I would break it in smaller chunks, for example 40 frames per second, break it in 8 per frame, it would slide through it how can I do such a thing in Flex ? if that isn't problem I would still have good ad to my Flex experience and future issues I didn't looked about how Flex execute larger chunks of code does it try to do it in one frame, or it's truly frame=free ?
[flexcoders] Convert Non-server Flex Project to Server Project
Is there a way to convert a non-server Flex project to a server project? When setting up a Flex project I can of course select the type. However, I need to convert a Basic Flex Project to a Flex Data Services project. Seems like the in the Flex properties for the project the Flex Server items are disabled when not creating the project as a FDS project from the start. I could import all the files to a newly created FDS project, but that seems a bit unintuitive. Thanks, Jurgen
Re: {Disarmed} RE: [flexcoders] Convert Non-server Flex Project to Server Project
Yeah, thought about that too. However, running this in Flex Builder on the Mac, it seems that those features are disabled on the context menu, even on another FDS project I have going.

[flexcoders] Flickr and Flex Implementation
I am working on a photo gallery app that is supposed to access private images from a Flickr account. While it's pretty straight forward accessing publicly viewable images from a Flickr user or account, there seems to be a big problem with accessing private images AND keep everything user friendly. Here is what I am finding: When using the Flex Flickr API, I get stuck with displaying a separate window to authorize the Flex application to access the private images. That's not the fault of the API, but rather a way Flickr is implementing their authorization scheme. From a user's perspective, this of course is silly for two reasons: Number one, why having a RIA that keeps everything integrated and then going outside of the web application to authorize access, and secondly, this exposes the Flickr account in the secondary browser window, which I definitely don't want. I thought I had found a workaround by simply just calling the authorization URL in a URLLoader like this: var auth_url:String = flickrService.getLoginURL( frob, AuthPerm.READ ); var loginLoader:URLLoader = new URLLoader(); var loginRequest:URLRequest = new URLRequest(auth_url); loginLoader.addEventListener(Event.COMPLETE,loginRequestComplete); loginLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR,loginSecurityError); In the loginRequestComplete method I then proceed to getting the frob. This works PERFECT on my local machine. I don't have to pop up a separate browser window to authorize the application with Flickr and everything proceeds to load the private images in the Flex application. However, moving this to the web site, I get the dreaded security error that states that the application cannot access data from the Flickr URL. I looked at the URLs. Here is what I find: auth_url in the above code snippet will start with http://api.flickr.com/services/auth/?api_key=..., targeting the api.flickr.com, for which Flickr has set up a crossdomain.xml file. However, to check what's happening with the authorization process I use the auth_url n a browser window and find that there is a redirect that happens back to a URL of http://www.flickr.com/services/auth/?api_key=... This means that my security error is triggered, because we are getting a response back from the flickr.com domain and not the api.flickr.com domain, at least that's what I assume is happening. So, long write up and short question: Has anyone made this work? What I am essentially after is a way to get to the private images through the Flex Flickr API without having to display the Flickr authorization window. Thanks for any suggestions! Jurgen
[flexcoders] Fade Effect and StartDelay Issue/Bug?
Seems like I'm having an issue with the Fade effect and using startDelay.
I have the following Fade effect defined:
mx:Fade id=fadeIn duration=200 alphaFrom=0.0 alphaTo=1.0
startDelay=1000/
This is used by a canvas component:
mx:Canvas id=myCanvas
width=400 height=400
visible={cb1.selected}
showEffect={fadeIn}
hideEffect={fadeOut}
mx:Button label=test/
/mx:Canvas
cb1 is a checkbox to play around with the fading in and out of the
canvas. I'm starting out with the Canvas supposed to be invisible
(checkbox unchecked).
Here is the problem:
When the visible property for the canvas is turned to true, Flex makes
the canvas visible instantaneously and then after 1 second does the fade
in effect. What should be happening is that the canvas is staying
invisible and then doing the fade in.
Anyone run into this problem? Seems like a bug in Flex to me, but then
again, I could be overlooking something.
Thanks,
Jurgen

[flexcoders] Scaling Fonts in Flex
This may be an odd one and I know that you guys are going to respond that you shouldn't really do this in Flex considering that Flex applications are something different than Flash movies. :-) So here it goes: Has anyone figured out a way to scale fonts (text, either with embedded fonts or system fonts) in Flex? Can it be done, and if so, what's best practice? Rather than resizing the label, text, or text area containers, I need to actually scale the font size in the objects. Thanks, Jurgen
RE: [flexcoders] Data synchronisation tip and tricks?
Very good topic! I'm working on a RIA using Flex that
deals with a similar situation for an online ticketing system. Imagine two or
more folks selecting the same seat and wanting to purchase a ticket for it.
Essentially this is collision bound, unless it is being handled
carefully.
I see two solutions:
a) Use Flex Data Services and it's real-time features
of updating clients with the latest status on a specific room (in your
scenario). This will not completely eliminate the possibility that both
customers want to book the room at the exact same time. However, it will cut it
down quite significantly. Of course, there is some additional stuff going on
that we would have to take into consideration.
b) Use flags in the database records for each room as
to its availability and return a response to a customer when the booking is
committed. If someone else has beat them to it, then an error would be returned,
eventually halting the rest of the transaction based on the fact that the room
now is no longer available.
This is a very birds-eye view of what would need to
happen, at least in my mind. There may be other approaches and solutions to this
problem and I would be interested to hear them!

Most of the traffic conversation here seems to revolve around

synchronisation of data in amulti-user application involving a
database.For example (since hotel booking is a prominent example in the
RIA world),lets suppose I have two customers (Customer A and Cust B) trying
to book thesame hotel room on the same day. Both see it as free in the RIA,
Cust Abooks it and now the other must know about it too, so effectively
thenthat's a straight refresh of Cust B display and the aborting of the
bookingin progress.Lets suppose my application allows Cust B to mark
several days of roombookings and (s)he has to hit 'book now' to commit to
the booking. Whilethis is going on 'Cust A' has booked one of those days, so
now I must mergethe updated database with the on-screen representation, so
it's no longer astraight replacement of the application display from the

database locking and handling that in aRIA.Get the idea? I

[flexcoders] Background Image Alignment using SWF as Background
I am using a CSS style to set the background of a mx:Box. The embedded image is a movie clip object from an asset SWF. Everything works fine, the SWF resource shows up in my application.
