Understanding Flex/Flex Builder

I'm very new to the Flex environment and I have a few broad questions I am hoping to get help understanding:
1) How does Flex work with ActionScript? Is there an ActionScript editor inside the Flex Builder app?
2) I want to import projects I developed from Flash into Flex Builder but they have timeline and ActionScript components - is this even possible?
3) Will objects I have layed out in Flash also be editable in Flex Builder?
4) Finally, should I just re-do the entire app in Flex?
The reason I am even considering using Flex is because of the ability to import text/xml data once and then compile a swf that doesn't call on the text/xml data at runtime.

1) How does Flex work with ActionScript? Is there an ActionScript editor inside the Flex Builder app?
When working with Flex, you use MXML and ActionScript, but after compilation it all gets compiled into ActionScript.
Flex Builder has an ActionScript editor, but it really just a text editor. Open an .as file and edit it.
2) I want to import projects I developed from Flash into Flex Builder but they have timeline and ActionScript components - is this even possible?
You cannot just import stuff you've done in Flash into Flex, and certainly not as a Flex project. But you can work in Flash and use what you have created in Flex. The Flex SWFLoader component allows you to load a SWF created in Flash and click its buttons, etc. access its data etc. Watch out though as there can be issues with versioning and security.
And then there is always Flex Component Kit for Flash.
3) Will objects I have layed out in Flash also be editable in Flex Builder?
No, you can access them and their data, but you can't edit them. You might be able to add components to containers in a Flash generated SWF, but it is not seamless by any means.
4) Finally, should I just re-do the entire app in Flex?
Hard to say. It is probably just a good idea to rebuild it in Flex, because if you are using snippets of ActionScript throughout the timeline, well that's why Flex came to be, Flash creates timeline based application nightmares, Flex is event based, which is what you want when creating real applications.

Problem with Flex Builder 3

Hey Experts,
I tried creating Flex Library Project in Flex Builder 3. No issues so far. Everything works fine. When the day ends, I close Flex Builder (without closing the project as it restores them during next launch). I had to close it...I can't keep the system running. Global warming you know...Next day when I launched Flex Builder, I could see my project there. However, when I open Project Properties dialog box, I get some errors while trying to open Flex Library Build Path or Flex Library Compiler pages. The error says "The currently displayed page contains invalid values."
C'mon man you gotta be kidding me. Yesterday you didn't say anything. What's the matter with you today. By the way, I didn't change anything in properties. How could I? I am unable to open it...
Does anyone understands Flex Builder's logic here?

Mate the first thing I tried was this...
If you want to see the problem, try crating a Flex Library Project in Flex Builder 3. Create couple of classes and close Flex Builder without closing the project. Re-launch Flex Builder and try to open Project -> Properties -> Flex Build Path or Project -> Properties -> Flex Compiler. You should be able to see the problem.

Can I re-install Flex Builder trial after 60 days again?

As far as I understand Flex Builder trial version stops working after 60 days.
Can I after the 60 days uninstall Flex Builder and re-install it again with 60 more days or does Flex Builder somewhere
(e.g. in Registry ) set a flag that Flex Builder was already installed?
In other words do the 60 days count per installation or per computer?
Peter

No.
But if you are a student you can receive Flex Builder for free (google it).
And of course you can use Flex SDK absolutely free with Eclipse (except Flex Data Visualisation components - AdvancedDataGrid, Charts).

Getting started with Flex Builder, BlazeDS and Eclipse

Hi,
I'm a java developer looking at RIA for the first time. I'm really excited about BlazeDS and object remoting, but I can't get a working dev environment together. I'm assuming I should use Flex Builder for the client code, Eclipse Europa for the java webapp code, and deploy from both IDEs into the BlazeDS-equipped turnkey-Tomcat. I haven't found a tutorial explaining how to deploy a new webapp with this setup.
The turnkey-Tomcat sample app works fine. Trouble starts when I try to create a new project in Flex Builder. I don't understand the 'debug' deployment that Flex Builder does. Why are there 2 versions of my app, the regular and the debug versions? What is exactly the project structure that I'm supposed to have in Tomcat?
The specific error I encounter when trying to deploy a new Flex project is this:
[MessagingError message='Destination 'productService' either does not exist or the destination has no channels defined (and the application does not define any default channels.)']
I do have a default channel configured for my environment in services-config:
And I do have a valid destination configured in remoting-config (I'm mostly interested in object remoting):
test.ProductService
Here's the client code:
What am I doing wrong? Where can I get help on these specific topics? Also, does anyone have an Ant build file that would automate this sort of deployment?
Thanks!

Hi Peter, I don't have problems passing JavaBeans to Flex. For collections, I used DataGrid, it displayed my collection seamlessly, except I don't get column headers, just a column index number. For receiving a single JavaBean, I had a little more trouble, until I tried to display it with a DataGrid: it displayed a single row that represented my data, with each java property name used as a column header, and object attributes were displayed as 'object'. These 2 experiences led me to these conclusions: - for the collection, Flex converted each element into an ordered list of attributes - for the single bean, Flex converted it into a hierarchy of Maps of attributes I didn't create a Flex value object. Flex is doing it automatically,very much like in JavaScript/JSON: dynamic objects. Here's the remote object markup:  <mx:RemoteObject id="myRemoteObject" destination="productService" fault="Alert.show(event.fault.faultString, 'Error');"> <mx:method name="getProductsCount" result="setProductsCount(event)"> <mx:arguments> <arg1>{productSC}</arg1> </mx:arguments> </mx:method> <mx:method name="getProducts">  <mx:arguments> <arg1>{productSC}</arg1>  <arg2>{pager.pageSize}</arg2> <arg3>{pager.currentPage}</arg3> </mx:arguments> </mx:method> <mx:method name="getProduct" result="goToView()">  <mx:arguments> <arg1>{selectedRecordId}</arg1> </mx:arguments> </mx:method> </mx:RemoteObject> And here's the dataGrid that displays the bean collection: <mx:DataGrid id="myDataGrid" dataProvider="{myRemoteObject.getProducts.lastResult}" change="selectRecord();" width="100%" height="100%" > </mx:DataGrid> Let me know how it goes, I'd be glad to assist if I can.

Flex builder 3 build release version error

Hi am a developer in flex for not too long. I am in a project that we use Flex 3 as our development tool in which we use external Actionscript classes and flash CS5 components (.swc) as well. Just recently the graphic team upgraded from CS5.0 to CS 5.5 and for some reason after they export the swc file from the flash source, I was not able to compile the flex project anymore throwing this error:
" Encountered errors or warnings while building project gTechLearning.as.
gTechLearning.as: unable to load SWC C:\Documents and Settings\rhampton\My Documents\Flex Builder 3\learning\libs\_assets.swc ".
So my question is simple, can anyone help me understand what is the cause of this error? Does it have anything to do with the version upgrade of the Adobe Creative Suite?
Thanks,
Ray H

Ok, solved the problem. Found answer from here:
http://forum.fluorinefx.com/viewtopic.php?f=9&t=3
I installed LCDS Express and then added fds.swc to my project
from LCDS-folder.

Flex Builder 3 under Eclipse - project .settings problem

I've been experiencing some odd problems with a project using FlexBuilder 3 plug-in with Eclipse.
The first problem I've noticed is that a file under the .settings dir has a red 'x' beside it. The offending
file is org.eclipse.jst.common.project.facet.core.prefs. I've left the file as is until I understand how it became corrupt.
The second problem is that .as and .mxml files are no longer being opened in the Flex Builder editor -
the are being opened in TextPad, which it the default editor outside of Flex Builder. I've tried all of the available
editors and none of them work under Flex Builder.
The third problem is that when I try to create a new Flex Builder project from New->Project-> there is no
option for a FlexBuilder project.
The Flex Development perspective is visible in the top right hand corner as usual. When I select Open Perspective
there is no Flex perspective.
Should I just reinstall the FlexBuilder plugin?
Thanks!

Hi Peter,
It has not been fully tested yet but a few of us are using
it. If you see any issues in Eclipse 3.3RC4 with FB3 Plugin, please
file a bug in our new public bug system:

Flex Builder 2 corrupting Eclipse 3.2.1

Flex Builder 2 has some issues with Eclipse 3.2.1. I was
working with the trial version, so maybe the full version does not
exhibit these same problems, but if that is the case, then it is
disappointing that adobe is trying to support two separate products
instead of trying to resolve issues.
The largest issue with the Flex Builder 2 plugin for eclipse
is that if you have a flex project in the same workspace as other
projects (like dynamic Java projects) the flex builder 2 will try
to incorporate those projects in to the flex project when you do a
build or a clean only on that specific flex project. As a result,
eclipse consumes enormous amounts of memory that even with 2 gigs
allocated to the heap, it runs in to out of memory exceptions
frequently and the stability of eclipse has degraded significantly
since I installed this product! The flex projects that I had loaded
were some of the examples dealing with SpringGraph so I would not
consider them as being large or complex. When there is a build
occuring on just a Flex Project, it SHOULD HAVE NO BUSINESS even
scanning other non-related projects regardless as to if they are in
the same workspace!!!
I am not too impressed with flex's interface with eclipse on
the memory, the instability it introduced to eclipse, or how
SpringGraph handles large graphs, so I did not pursue getting a
license for future development. I also felt that the asking price
for the Flex Builder 2 is steep for what you get and its maturity
level. As such, when the license expired, Adobe had the nerve to
disable core functionality within Eclipse!!! For example, it would
not allow a CSS document to be opened in the CSS Editor! It
Hijacked the basic Eclipse functionality!!!
I am very disappointed in how the Flex Builder 2 plugin for
Eclipse does not play friendly!
But at least it does allow itself to be disabled. I am
grateful for at least that level of accepted behavior.

Cluebcke, thanks for the reply!
I am using a compaq nx7010 laptop with 2 gigs ram, 60 gig hd,
eclipse is set to utilize a minimum of 512 megs and a maximum of
1540 megs for the heap space. Virtual memory is set to a max of
4092 megs. Fairly generous I would assume. I doubt it was a
configuration issue, but hey, I’m open to learning and the
best lessons are through mistakes! ;-)
Sorry, I was being a bit sarcastic when I mentioned that
perhaps the issues were related to the free trial version knowingly
perfectly well that in fact there is no difference between the two
products. But I guess I was also conceding a possible out for Flex
too. Hmm...
To clarify my comment about aggressively compiling against
other projects:
1) I had about 4 demos loaded in to a workspace (269 files,
82 folders, and 7.2 megs including my 1 test project as mentioned
in item 4)
2) I had about 7 large Java projects loaded in to the same
workspace
3) Total workspace size was about 22,000+ files and 1600+
megs, give or take a fair number either way.
4) I was making changes to a simple flex project based upon
a SpringGraph demo
5) I choose to manually build only the small flex project I
was working on so as to replace all the generated files. NOTE:
Might have been a clean, but only on that one flex project and NOT
the whole work space. It takes too long to rebuild all of my other
Java projects so that option has been unchecked for quite a while.
6) What I saw in the Eclipse progress window was a list of
files within my flex project getting reconstructed, and then it
started to scan through the other projects too. All of their names
and resources were flashed within that window.
7) When finished with the build of the ONE flex project, the
Java heap was basically gone. Starting a TomCat server would cause
an out of memory exception. Recall I have allocated 1.5 gigs for
the heap.
8) Checking the other Java projects and Flex projects, the
timestamps on the objects did not reflect that they were just
rebuilt. They were untouched. Proof that I did not perform a build
or a clean over the whole workspace.
I agree with you whole heartedly that unless I explicitly
select “build all” or “clean all” it should
not touch other projects in anyway. But it did.
As far as the issue with the CSS editor, I understand and
accept your point. Perhaps as a friendly suggestion, when the trial
expires, the plugin should uninstall itself. This may be very
doable, and still have the functionality of a reminder and
reactivation upon registration if Flex Builder actually had a
second plugin called something like "FlexBuilder Registration"
which would "intercept" attempts to edit and utilize the
FlexBuilder only functionality so an informative message could be
displayed. The benefit would be that normal functionality for
non-flex resources such as CSS would return to normal.
Anyway, as I stated before, I was not too impressed with
performance of large graphs. What I consider to be large would be
on the magnitude of 20,000 to 100,000+. It would need to display
just about all nodes, or at lease an abstract relationship of those
nodes rolled up to a higher level. I realize that SpringGraph is
not ideal for those situations to begin with, but I was exploring
the idea of writing other plugins to deal with other graphing
formats.
I guess to be fair to Flex in general, I should probably ask
a general question of how well does Flex deal with large data sets
that need to be resident and the manipulations of those data sets?
Thanks for your time,
Scott Tabar

Code Collapse/Folding in Flex Builder?

Hi,
I am using Flex Builder. Is there a way to keep my code collapsed/folded? If I open up a file with a ".as" extension I can collapse my functions but they don't stay collapsed when I re-open the file.
1. Is there a way to keep the code folded so it stays that way until I unfold it?
2. Is there a way to somehow have code folding in .mxml files?
Thanks,
-Westside

Yes, I understand how to do that. Cold Folding is already enabled. The problem is if you close/collapse a function then close/re-open the file the functions revert back to open. So if you have a lot of functions in a Class its nice to be able to collapse the other code when your not working in it. It also makes scrolling in the file much quicker when everything is collapsed and stays collapsed.
-Westside

Best practice. Flex Builder / Form Guides

Hi,
We have a quite complex form which requires functionality not present in Form Guide Builder.
My question is what would be the best way to go about this.
Create the entire layout in flex builder and later bind the form fields to it?
or
Create the layout in Form Guide Builder, bind the fields and then use Flex Builder to make final adjustments?
Kind regards
Lars

I am not sure that you are understanding how form guides works. Form Guides leverage the XFA template design in Designer to allow you to have an alternate interface for collecting data. The structure of the guide is built in Guide Builder but the underlying definition for the template is in the XFA template in Designer. The only time that Flex Builder would be required is if you wanted to modify individual components or layout styles. So to answer your question build the form in Designer then use Guide Builder to bind the individual fields and objects to the appropriate panels.

Design Flex with Fireworks CS4 or Flex Builder?

I need help in making a process decision on how to build Flex
Apps going forward.
In the past, we have built the concept for our Flex app in
Photoshop and sent it over to our development team in India to
build. The process has been difficult because our engineers are not
designers and our designers are not engineers. Invariably we spend
alot of time bridging the gap between whats possible and what we
want to see in our Apps.
I want to bring our Design and Dev much closer together and
essentially take the GUI out of the hands of my Indian Developers
who choose to work in raw XML rather than Builder today.
To accomplish this goal, I will be training my US Design team
to become either Fireworks Experts or Flex Builder Experts....
(they are already Photoshop experts) This is where I need your
help. If you were starting from scratch with a talented design team
that could learn either tool, which one would you choose to
accomplish the goal? Does the Fireworks to Flex export create
crappy code like Dreamweaver thats tough to modify manually? Does a
"true" Flex developer despise Fireworks-generated code?
I have read up on the Fireworks>Flash Catalyst>Flex
Builder Path and dont understand the additional step... is Catalyst
part of Fireworks and thats how Flex code is developed or is it a
new code generation engine that does code better than Fireworks
CS4?
Thanks in advance.

Here's my recommendation:
I would suggest Fireworks for your Design team/ Flexbuilder
for your dev team.
Essentially, what Fireworks already has in terms of Flex UI
components (though a short list) is identical in theme (default
halo) AND output (mxml code) as you would expect from creating in
Flexbuilder alone.
You can then easily extend your designs with custom
components using the Fw Commands Export Flex Skins and they can be
imported to your Flex project using the CSS Designer.
As for Catalyst, this is a separate beast altogether. It's
merely meant to bridge designs (from design applications Ps, Ill,
Fw) and create usable components for complete animations.
A full tutorial/ video overview was just released a few days
ago here
http://blog.digitalbackcountry.com/2009/01/getting-started-with-flash-catalyst-tutorial/
As for how Fw fits into the Catalyst scheme of things,
designs you create can be exported to the FXG format that Catalyst
will use, if you want to use Flex and work with this format you
have to have the latest Flex SDK plugged into FlexBuilder 3 or Flex
4 will have full support for it.
Here is an older referebce to this scenerio (reference to
Thermo = Flash Catalyst and Gumbo = Flex 4)

Flex builder 4.0 ( mx:Script )

Hello Gurus,
We downloaded Flex builder 4.0 trial version for 60 days to learn Flash Island on webdynpro.
Now, we are facing a small problem that <mx:Script> tag is not working. Could be a missing library file...
Please help to resolve my problem.
Regards,
Abhishek.

Hi Abhishek,
It's may not be the case of any missing file.
Flex 3 Application codes may not be getting compiled as there are some differences in tag declarations and classes.
You can test any sample application which you can easily get from Tour de Flex examples to test Flash island in WD.
Note that you also need WDIslandLibrary 'SWC' file for same version compatibility.
If you want to use your own application then refer following links which will help you to understand the transition of Flex 3 applications into Flex 4.

Flex Builder 4 == Flash Builder 4

I've seen a ton of blogs discussing Adobe's decision to rename Flex Builder to "Flash Builder" for version 4.0, and wanted to see what you all think.
Personally I agree with many of the blog comments that it is a bad move.
Flex apps are not Flash apps (thankfully), they just happen to run in the same runtime (Flash Player). AIR apps are not Flash apps as well.
I still think Flex will succeed, but are you all looking forward to working in Flash Builder 4?
I for one hope Flex continues to succeed despite this move.

Just recently re-infuriated by this terrible decision on Adobe's part so I located this thread.
On Adobe labs they use this as the reasoning:
If you are new to the Flash Builder beta, the first thing that you’ve already noticed is that we are renaming Flex Builder to Flash Builder. This name change will create a clear distinction between the free open-source Flex framework and the commercial IDE.
So instead of developers (most of which have already learned the distinction by now after TWO versions) having to know the difference between an SDK and an IDE (what kind of idiot developers can't understand this???), now Flash designers (many more of those) and programmers also need to understand the difference between Flash Builder and Flash Professional. They aren't the same product in the least and are barely related, but Flash "newbies" won't know that from the names. Meanwhile Flex newbies will still be confused by the Flex SDK/Flash Builder mismatch.
You would think that Flex devs (many of which come from the Java world which has exactly the same concept of SDK/IDE) who are familiar with software engineering (unlike your typical Flash developer), would be able to overcome this "confusion" more easily than the much larger number of Flash devs.
So now this change is needed, to add even more confusion for everybody involved:
When Flash Builder 4 is released for purchase, the current plan is to name the full-featured edition Flash Builder 4 Premium edition. This change is being made to reduce any risk of confusion between Adobe Flash Professional and Adobe Flash Builder.
If it's already realized that you're just replacing the confusion of Flex newbies with the confusion of both Flex AND Flash newbies... why do it?
Was this some over-paid executive's knee jerk solution to an almost insignificant problem? Given that it seems almost nobody thinks this change is a good idea, perhaps they should have asked (here or elsewhere) their customers what they thought of such a change before simply announcing it and passing it off as a big marketing improvement?
But more importantly: Is it too late to reconsider this idiocy? (I can't wait till Google searches start mixing up Flash Pro and Flash Builder information making it just that much harder to find relevant links!)
If you really want to eliminate the confusion of "Flex Builder" vs "Flex SDK" for the mentally challenged, why not simply rename Flex Builder to a more creative and unique name similar to what Java has in Eclipse/JDK? Heck even calling it FX Builder would have been better than Flash Builder! The marketing dept here needs a serious wake up call IMO.

Bug in the flex builder installer

I found a bug in the Flex builder installer, while someone
tried to install Flex on top of our EasyEclipse eclipse distro.
I am making a post here since I could not find a way to
report a bug anywhere on the Adobe web site :-\
So the bug is that the installer is looking for an eclipse
installation that is packaged exactly like the Eclipse platform,
but also specifically checks for the presence of features named
org.eclipse.rcp and org.eclipse.platform.
Yet the flex features themselves do not care about other
features only about the platform plugins to be present, as it
shoudl be.
It is considered a bad practice by the Eclipse platform team
to have a dependecy on features, and it is recommended to use
instead plugin depdencies.
See
http://wiki.eclipse.org/index.php/Version_Numbering#Versioning_features
As a result, Flex cannot be installed anywhere but on a vanilla
Eclipse.
EasyEclipse does not ship the base features of the Eclipse
platform, yet all the Flex plugins dependencies are statisfied.
See our forum for more details:
http://sourceforge.net/forum/message.php?msg_id=3982548

Getting back to the original message in this thread, I want
to post an update about what I learned on digging deeper. The Flex
Builder 2.0.1 Plug-in version does not require a vanilla eclipse to
install into, but it does impose some minimal constraints. Before
release, we installed FB 2.0.1 Plug-in successfully with several
customized Eclipse configurations, including RSA7 and BEA, each of
which uses a different folder configuration for its product
extension point.
I took a close look at the dependency list for our FB 2.0.1
features, and these have been plugin-based dependencies all along,
not feature dependencies. I understand why it might appear as if
they're feature-based though, because our installer requires that
the feature named org.eclipse.platform be present.
We have the installer look for that feature, because that's
the way Eclipse's update manager reports what's already installed
and available. Eclipse's commandline API for updates only provides
Feature info, not Plugin info:
http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse.platform.doc.isv/reference/mis c/update_standalone.html
The FB Plug-in installer checks for the existence of
org.eclipse.platform so that we have some assurance that the
version of eclipse proposed is at least version 3.1.2 or higher. In
our next release, we'll explore alternate way of gleaning this same
information, with the intention of allowing plug-in installs into
products such as EasyEclipse that don't include any Eclipse
features in their products.

Difficulties using Flex Builder plugin version

The strangest thing just happened. I want to look into Zend, so after reading a bit on the web I decided to uninstall Flex Builder 3 standalone version and install Eclipse 3.4 and then install the plugin version of Flex Builder 3.
But after I installed when I click on the Run button I get an error message:
'Launching cmd' has encountered a problem.
Variable references non-existant resource :
${workspace_loc:/Misc/src}
I assume this is because users need prior experience with using Eclipse, but I don't understand why the Adobe plugin version of Flex Builder cannot be such that it just works out of the box.
I have to say I am blown away by this and will immediately uninstall the plug-in version and re-install the standalone.
Any hints on what went wrong? I may try this again sometime but I want to get some work done tonight and I don't have time for this. Really amazed.

Hi Greg,
I am using the Flex Builder plug-in and I don't remember ever running over this. You said that you have uninstalled Flex Builder before installing Eclipse. I'm not sure ( this is only a guess ) but what if certain setting that you had in Flex Builder remained on your system ( like the path to your workspace that I think got deleted when you uninstalled it ) and when you installed Eclipse, then it was trying to access the information previously stored by Flex Builder.
I'm not sure if that's what the Error says but you might want to check if you workspace still exists and if it does, then does it contain a folder called "Misk/src". I really don't remember running over this error, the Plug-in worked just fine for me.
With best regards,
Barna Biro
