Jazz and Flex Builder 3

(I've also posted this in the forums over at
jazz.net)
I'm trying to get Flex Builder 3 to work with Rational
TeamCentral (the beta client for the Rational Jazz system). Jazz is
an IBM Rational project to build a scalable, extensible team
collaboration platform for integrating work across the phases of
the development lifecycle. Alas, I'm running into some problems
under Windows. I'm doing all this with TeamCentral Beta2a, BTW.
My first approach was to unzip the Beta2a client on my
Windows laptop and install the Flex Builder 3 plugins. In this
configuration I was able to get Jazz to work, but whenever I try to
build anything using Flex I get what looks like a Xerces versioning
problem. Here's a part of the exception I get whenever Flex tries
to build anything in this configuration:
ENTRY com.adobe.flexbuilder.project 4 43 2008-03-02
09:31:11.062
!MESSAGE Uncaught exception in compiler

Source)
My next attempt was to use my Macbook and install the
TeamCentral client with the Flex Builder 3 plugins (same
configuration that I had just tried on Windows). This worked
perfectly - both Jazz and Flex were very happy, and I could be
productive here. Unfortunately, most of my team members are Windows
developers, so this is not a viable solution for them.
Now back to Windows. I installed the Flex Builder 3
standalone eclipse instance and noticed that it uses Sun JDK 1.5,
so I wondered if the JDK was the culprit. I replaced the JDK to use
the IBM 1.5 JDK (same as TeamCentral Beta2a). The standalone Flex
Builder 3 worked.
My next experiment was to use the Sun 1.5 JDK on TeamCentral
with the Flex Builder plugins. The performance seemed very
sluggish, but Flex seemed happy. Jazz was a different matter. I
could connect to a repository and connect to a project area, but I
couldn't do anything after that. I couldn't see any workspaces that
I had, nor could I look at streams, work items, etc.
I'm out of things to try at this point. My ideal solution
would be to figure out how to resolve the Xerces incompatibility,
but I'm open to any other ideas that people might have. We've
discussed the idea of having separate Jazz and Flex instances
running to get the Jazz features, but running both Eclipse
instances is quite expensive resource-wise, so an integrated
solution is the best.
Thanks in advance!

Apollo and Flex Builder?

Hello,
I am wondering what the difference is between AIR (Apollo)
and Flex Builder 2/3. Also, is the Flex Builder application worth
the money, or is it fine to just use the SDK (I have programmed
with ActionScript, Python, and Java before, so I think I will
understand it).
Thanks,
Dylan

Both are same. I am simultaneously using them. For Flex 3.0 separate installations are coming but same license key.

ColdFusion RDS and Flex Builder 2

Hello everyone.
I try for 3 days to get this running but I keep getting the
same error:
"The RDS server was successfully contacted, but your security
credentials were invalid."
The documentation says that if you are using ColdFusion MX
7.0 or earlier, you would get this message.
But I am using the ColdFusion MX 7.0.2 Developer Edition,
Running under IIS6 on a Windows 2003 server Standard.
Please note that the ColdFusion and Flex Builder 2 are not on
the same computer and it is not possible for me to install CF on
the local computer.
If I try the Dreamweaver RDS it works fine. So I know there
is nothing wrong with the password, the Host Name or port 80.
Can someone please help me?
Thanks.
Sam

anyone??

Need Info NativeProcess and Flex Builder

Hi Guys,
I am currently using Flex builder 3.0 and wanted to develop a project with the new Air 2.0 features
I have done following process for Air 2.0
·         Downloaded Flex 3.3 sdk.
·         Downloaded Air 2.0 sdk
·         Updated Air sdk of 3.3 to 2.0
·         Changed the namespace to 2.0
·         Added “supportedProfiles” tag to –app.xml file
Now when I try to import NativeProcess I am unable to find in package flash.desktop , is there is need to update my Flex Builder, also if not what am I doing wrong please suggest.
Thanks & Regards,
Mahesh

HI ,
For importing class of native process ,
Download sdk 3.4
Download AIR2.0 SDK
Now update air library of 3.4 with AIR 2.0 SDK - for that just copy of AIR2.0's sdk content and past this into SDK 3.4's content.
Now your library is able to handle native process.
Now you can import native process class.
When u want to call native process at that time u need to add
<supportedProfiles>extendedDesktop desktop</supportedProfiles>
into your project app.xml
Now you can use nativeProcess class of AIR 2.0

Debugging with External Browser and Flex Builder

Hi
I have Flex application that requires you login first in IE
before you can have access to it (ouside the application)
I would like to debug this application but when I start the
application from Flex Builder , it is always opening new IE window
How to attach Flex builder debug session to an existing IE
session (that was authenticated already)
I tried going to Window/Preferences/Web Browser and tell it
to use 'External IE Browser' but that did not work
any help is appreciated
Thanks
Kasem

Hi Kasem,
If you go to the launch configuration dialog for your
project, you can set the launch URL to any URL you want -- you can
set it to point to your login page.
The quickest way to get to the launch config dialog is to
click the Run or Debug toolbar button, and then CONTROL-click on
the launch configuration you want to edit, But you can also get to
it from the Run menu.

Flash Player 10 and Flex Builder 2

I need to have flash player 10 installed on my local machine for my time tracking software. With that I am no longer able to run my flex builder in debug mode. I am no longer able to see any of my trace() statements executed.
Is there any way to have Flex Bulder 2 run with Flash Player 10 in debug mode?

Try targetting the flash player 10 in your project setting.
Sincerely,
Michael

You may need to install Flash Player 9.0 or reinstall Flex Builder.
Do you want to try to run your application with the current version?

I googled the crap out of this and all i got was to reinstall flex

Flex builder and snow leopard problems

Since upgrading to Mac OS X 10.6, Flex Builder is functioning extremely poorly. The worst issue is that I am experiencing extreme slowness when typing code. I type a few letters and then have to wait a few seconds for my text to fully appear. The is happening in both Flash Builder beta and Flex Builder 3. There are also some other quirks--the column down the left side of the editor, where line numbers appear, periodically stops updating so that error and debug markers never disappear until I restart Eclipse.
Does anyone have any suggestions as to how I can at least fix the text issue?

Wow, you're completely right. I hadn't noticed the second monitor issue until just now because Flex/Flash Builder is almost always on the second. Line numbers scroll just fine on my primary monitor.
Also, has anyone noticed a crazy amount of CPU usage when Flex/Flash Builder is Building the workspace or launching the application? When I look at the processes in Activity Monitor, a process called "fontd" uses ~95%. I've done some searching and all I can find is it has something to do with system fonts. Most people recommend clearing your font caches by booting into Safe Mode and/or using Font Book to resolve any duplicate fonts. I've tried both multiple times, yet the problem is still there. Any ideas?

Eclipse 3.2 / Flex builder and Leopard

Anyone know if Eclipse 3.2 (not the latest one since it
doesnt support flex builder 2) and Flex builder 2 will work on
Leopard?

Can you ensure that the SWF your are debugging is a release SWF?
I've recently fixed a bug (which is not publicly available) where the same stacktrace was visible:
A release SWF loads a debug SWF via SWFLoader/ModuleLoader, etc.
Making sure the main container SWF is a debug one. That should fix this problem.
(You can check whether a SWF is debug or not by opening it in nemo440 (google for that) and looking for debugfile / debugline opcodes.)
Let me know how it works out.
Cheers,
Anirudh

Flash builder 4 and flex 3 sdk - co-existence?

Can I install Flash Builder 4 Premium on the same XP machine with Flex 3 SDK without conflicts?
Thanks.

Yes.
Perhaps you meant to ask about Flash Builder 4 and Flex Builder 3 co-existing? If so, then yes, you can also have Flash Builder 4 and Flex Builder 3 on the same machine without any conflicts; although I would not recommend installing them in the same eclipse instance.
You can also have as many Flex SDKs installed on your machine at a time and have Flex Builder 3 or Flash Builder 4 setup to use all the SDKs. Although, I don't thikn it is possible to use use more than one SDK as part of a single project. it'd be impractical, if not impossible.
I think that covers all bases.

Flex Builder 3 Error: Unable to load SWC

Hi,
I am trying to use the YahooMaps component (YahooMaps.swc) in
my application. I have included it in the build path of my
application.
Steps followed:
1. Right-click on the project and choose Properties or open
the Project menu and choose Properties.
2. In the project properties dialog, choose Flex Build Path.
3. Select the Library path tab, and press the Add SWC...
button.
4. Selected the YahooMap.swc
I still get "Unable to load SWC: YahooMap.swc". It is an AS
3.0 component. Any help will be appreciated.
Thanks
Sumit

Hi Peter,
Thank you for your reply.
I have followed the documentation on the site you provided.
All I have done so far is:
1. Create a new flex project in Flex Builder 3
2. Once the project is created, I try to add the YahooMap.swc
to my Flex build path.
3. Once I add the YahooMap.swc, it fails with the error
"Unable to load YahooMap.swc" in Flex Builder 3.
4. FB3 does not recognize YahooMap when I try to import it in
AS3.
import com.yahoo.maps.api.YahooMap;
I am not sure what I am doing wrong. Does it have to do
something with the version Y! has used to build the YahooMap.swc
and Flex Builder 3?
Thanks
Sumit

Flex Builder 3....Not launching?

Whenever I press F11 to launch my flex/air project it does not launch. The red square shows up in flex builder and flex builder seems to think it is open but there is nothing there. Also if I check my system processes, it says that adl is running, and it also says that javaw.exe is running at 50%. (I believe javaw.exe is flex builder as flex builder closes if I end that process.)
Any ideas?
Thanks.

Hi Michael,
Thanks so much for all your help!
I just installed FB 3 again, but still no love, yikes! I
don't get it FB 2 was painless,...
I have the same issues, and safari does not handle any flex
apps, just a blank(grey page). Can I ask a favor? Can you check
this link, a flex charting app. It can view it perfectly in Camino,
but just a blank page in safari. Could you check this link in
safari?
http://cfhawaii.com/Charts/DrillDownWithEffects.html
I also still get the can't find the debugger player.
Maybe I need to take a on-line course(bring that I am in
hawaii) to learn how to get everything set up.
I send a bug report to adobe, and I am hoping that somebody
gets back to me, and can help me fix the problems, as I couldn't
even registrar FB3, I want to start learning flex, not dealing with
this.
Thanks so much for all your help`-`

Flex Builder 3 Backwards Compatibility

Hello,
I was wondering which versions of Flash are Flex 3 and Flex
Builder 3 compatible with. The clients I'm building the Flex app
for are still on 9.0.16.0, on an isolated network, and may be
awhile till they upgrade. Is FB3 compatible with that version, or
is there a compiler option to make it so? I noticed for instance
that a simple ComboBox wouldn't work in that version - it caused
the Flash page not to completely load. It did work with a later
version of flash, so I suspected it is a compatibility issue.
Thanks,
Dan

Flex 3 requires player 9.0.115. But, in FB3 you can set the
compatibility version so you can compile against the Flex 2 SDK
which can be run by earlier versions of the player.
To do this select Project > Properties > Flex Compiler.
Select "Use a Specific SDK" and then select Flex 2.0.1 Hotfix
from the drop down.

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 vs. Flash Builder 3 or 4 Differences ?

I have poked around a little for this answer, but i dont want to spend all day doing so as Flex / Flash is not my full time job i am not hip to all the proper places to go to find the correct answers.
Today i bumped into adobe labs, where i saw that there is Flash Builder 4 Beta out. I downloaded it and it looks much like Flash Builder 3 which i own.
What i would like to know is 2 things.
#1) what is the difference between Adobe Main site (which does not even show Flash Builder for their products) and this Adobe Labs site which does show it.
#2) what is the differences between Flash Builder and Flex Builder ?
Thanks

It figures, that as soon as i posed this i found the answer to my questions.
FWIW, here is the answer.
http://labs.adobe.com/technologies/flashbuilder4/?tabID=details#FAQ
Please feel free to corect me if i am wrong, but the way i read it and interpret it is that Flash Builder 4 will replace Flex Builder.

Flex Builder 2 OutOfMemory Exception

I am having a memory problem with both Flex Builder 2
standalone and Flex Builder 2 eclipse plugin.
I've developed a flex component library that is approximately
1.8MB (as far as the size of the project folder). Whenever I start
flex builder I get the following error message found in the
.metadata/.og file:
ENTRY org.eclipse.osgi 2007-07-31 09:56:53.343

at java.security.AccessController.doPrivileged(Native
Method)
at java.net.URLClassLoader.findResource(Unknown Source)
etc. etc. etc.
The only way I am able to work around this problem is to
remove the entire project folder from my workbench, start flex
builder 2, then copy the project folder back into eclipse. I then
have to follow a few more steps (re-adding .swc files,
re-establishing dependencies between projects) before I can begin
work.
I have tried modifying my flexbuilder.ini file and this does
not make a difference.
Current contents of flexbuilder.ini file (as suggested in
another, similar thread):
-vmargs
-Xms512M
-Xmx512M
-XX:MinHeapFreeRatio=20
-XX:MaxPermSize=128m
-XX:PermSize=128m
My computer has 2GB of RAM.
Any suggestions?
