Upgrade from Flex Builder 3.1 to Flash Builder 4.5

I have several project in Flex Builder 3.1 now.
What is the best way to move them in Flash Builder 4.5? Can I just use the workspace from Flex Builder 3.1 in Flash Builder 4.5?
Is Flex 4.5 backward compatible at API level?

You should always have separate workspaces for separate versions of Flash Builder.
Flex 3 and Flex 4 have some large differences. You will probably want to spend some time reading about migrating by searching on Google. Here is a good place to start: http://www.adobe.com/devnet/flex/articles/flex3and4_differences.html

Upgrade from Flex Builder 3 Professional to Flash Builder 4 Standard?

Hi,
I currently own a license to Flex Builder 3 Professional, and I would like to upgrade to Flash Builder 4 Standard. I do not need the extra features included in Flash Builder 4 Premium, and it costs three times as much as the Standard upgrade.
However, none of the upgrade pages say if my particular upgrade path is possible or not. I talked to a sales rep on the phone, and he thought it would be fine, but didn't know for sure. Can anyone give me the official word if it is possible to upgrade from FB3 Pro to FB4 Standard?

Hi,
I don't think that "downgrades" from FB3 Pro to FB4 Standard are officially supported. You might be able to negotiate with a Sales Rep to make an exception for you though, for a discounted price on a non-upgrade version of FB4 Standard.
Alternatively, if you have any interest in CS5 Web Premium (or have any Adobe products qualifying for a CS5 upgrade), FB4 Standard is included with that Suite now.

Issues migrating from Flex Builder 3 to Flash Builder 4.5

Migrating from Flex Builder 3 (SDK 3.5) to Flash Builder 4.5 (SDK 4.5). Using Flex 3 compatibility mode. Flash Player 10.2. MX only components set.
Issue 1. A DataGridColumn error per: Description Resource Path Location Type
Declaration of style 'direction' conflicts with previous declaration in C:\Program Files (x86)\Adobe\Adobe Flash Builder 4.5\sdks\4.5.0\frameworks\libs\mx\mx.swc(mx.controls.dataGridClasses:DataGridColumn). SPT_GUI Unknown Flex Problem
Issue 2. Using Cairngorm 2. Have a class 'Bindable] public class GuiModel implements ModelLocator'. Now getInstance() is not defined per: private var model : GuiModel = GuiModel .getInstance(). Does Cairngorm 3 have to be used with Flash Builder 4.5?
What has to be done to resolve these issues?

Issue 2: Have you defined the static variable to hold the instance of the model locator? Also, have you defined a static method to return the model locator's instance?

Design view not working after importing project from Flex Builder

After importing a project from Flex Builder to Flash Builder I am no longer able to see anything in the design view. I am using the flex 4.5 sdk.
Any idea how I can get this design view working? I heard it could have something to do with the metadata directory but am slightly lost here?...
Adam

Could you please provide more information as to what exactly are you importing. Also does Design View not lauch at all or does it give errors. Would it be possible for you to share the logs.
Meanwhile you can try cleaning the workspace and importing again to see if that solves the issue.

Building from flex builder vs ant task

I have a flex application written using flex builder. When I
build it and run it using flex builder, or create an air file from
flex builder and run that, then my application works just fine.
However, I would like people without copies of flexBuilder
installed to be able to build my application, so I am using the
flex ant task (flex-mxmlc) to build my application. As far as I can
tell I have the same configuration, and the same libraries included
in the ant task. However, when I run the air file generated by the
ant task nothing happens. If you look in the task manager, you can
see that the application is running, but the main window for the
application never appears.
I tried running the swf through a debug version of flash to
get some log output, and I am getting a bunch of exceptions, the
first of which is:
VerifyError: Error #1014: Class flash.display::NativeWindow
could not be found.
at flash.display::MovieClip/nextFrame()
at mx.managers::SystemManager/deferredNextFrame()
at
mx.managers::SystemManager/preloader_initProgressHandler()
at flash.events::EventDispatcher/dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at mx.preloaders::Preloader/timerHandler()
at flash.utils::Timer/_timerDispatch()
at flash.utils::Timer/tick()
It seems like it might not be finding the main flex library
(flexlib.swc), is that where that class would be? In my ant task I
have an include-libraries tag that points to that file.
Anyone have any ideas?

I experienced a similar problem (although the class that
could not be found was different for me). Googling around I found
someone who had a similar problem and claimed that using the
flexlib.swc library was the culprit.
The root of the problem is that the Flex SDK that comes
bundled with the Flex Builder has libraries (under frameworks/libs)
that are NOT included in plain free Flex SDK that you and I are
presumably using on our build machines.
When flexlib.swc is linked in, it causes certain classes to
be required at runtime. Apparently when you compile these classes
are linked in if available, but when they are not the compilation
still succeeds. Only you get a VerifyError when you run the thing.
What worked for me was to copy all the additional .swc files
found in my Flex Builder SDK's frameworks/libs directory to the
same directory on my build machine. Also you will need to copy the
additional files under frameworks/locale/en_US.
Rebuild and clear your browser's cache and it should then
work.

Flash builder 4 upgrade from Flex 3 Standard

Hiya.
I would like to know from Adobe if the upgrade options available a wrong or not? I've just bought an upgrade from FB3 Standard to FB4 Preminum (from Eligibility chart is SEEMS possible). The installer when I entered my FB3 Standard serial says it's wrong. At this point the possible answers are two for me: the upgrade processes on the site is wrong or there's something wrong with the installer. A would like a clarification as soon as possible.
Thanks.

I run into the same problem.
For me it was the only option available at the adobe online store (upgrade Flex3 -> FlashBuilder4 Premium)
so the registration number didn't work, saying that i have the wong product to upgrade (Flex3 standard)
I had to open a case for software destruction to get a refund for what i've allready payed and if i want the FlashBuilder4 serial i have to re-buy it at the online store
Custumer support told that this is the only solution.
It's a little bit annoying.
That is not a critic to the support team (was very friendly) it's just annoying that i can't get a standad serial for my purchase and that i have to wait some weeks to get the refund...
So be carefully while purchasing the upgrade and look twice to choose the right option at the store.
(Hopfully the right option is now available...)

Install Flash Builder 4.5.x Upgrade without Flex Builder 3.x installed?

Edit: Is the lack of replies because no one knows the answer or because this was a ridiculously dumb question?
Also, if I must have a prior version physically installed to do the upgrade, can I install Flex Builder 3 on a temp Windows machine, upgrade that to Flash Builder 4.5.x and then transfer the license to the MacBook? Seems like a very convoluted way of doing things but if that's the only way then I suppose I can go scrounge up a spare computer to do so. End Edit
Hi,
I just got a brand new MacBook Air which has Lion on it.
I have an unused boxed copy of Flex Builder 3.0 standard edition.
I tried to install 3.0 and of course I got an error along the lines of not compatible.
What I would like to do is upgrade to Flash Builder 4.5.
So the question is,
Can I buy the upgrade edition of Flash Builder 4.5 standard for Mac, then install that on my MacBook even if I don't have 3.0 installed to upgrade from?
Is it as simple of just supplying the seriel number from 3.0 when upgrading?
Thanks.
Message was edited by: Cindered Monkey
Changed the title to better reflect the situation.
Also added a blurb to the top.

Well, thought I should update just in case someone else has a similar thought.
I ran out of time to wait and it seemed I wasn't going to get a response so took the chance and bought the upgrade.
The install couldn't find any prior versions so just asked for the serial for Flex Builder 3.0.
After entering that in, it thankfully installed just fine.
Would have totally sucked if it didn't work and was forced to then buy the full version.
Anyhow, relieved it worked.
Regards.

How to migrate a flex app from Flex Builder 3 to Flash Builder 4.7

Hello,
I have written an extensive application using Flex Builder 3. I have maintained the app for several years using FB3. In the mean time I have created several mobile apps using Flash Builder 4.7. So I am very familiar with the the new framework. However, my client has requested some big changes to the app. I figured this would be a great opportunity to migrate the app to FB4.7. I would like to keep the mx structure for the time being. So, are there any good documents concerning this migration path? What SDK should I use. Should I start using the Apache Flex SDK?
Thanks,
--randu

Hello Raja,
Thanks. Your reply has been very helpful.
For deploying the Flex app, as a web on NW 04S, I did the following:
- Created a web project and included the following files as web-content. These files were created using the Flex builder or in the Flex development perspective of NWDI - CE, you can find them in the "bin" folder of your Flex project.
   - AC_OETags.js
   - your-app.html
   - your-app.swf
   - history.htm
   - history.js
   - history.swf
   - playerProductInstall.swf
   - crossdomain.xml - This file is important, if our Flex app wants data from the server.
    ( I made the simplest possible crossdomain.xml containing
       <allow-access-from domain="*" secure = "false"/>
- Declare "your-app.htm" as the welcome file in web.xml
- Package, this .war after building this web project in an Enterprise application project and build it.
Now, you have the .ear made, which is deployable on your NW Web AS.
Apart from this, another thing which is important to be included in your Flex mxml code is the following:
( Thanks to Abesh for this........ )
- You have to tell the Flex app, in the action script, as to from where should the Flash engine pick the crossdomain.xml ( in case you are accessing the server for data from your app)
You might have noticed, we packaged the crossdomain.xml along with our other web content in the .war.
So mention, something like this in your action script.
Security.loadPolicyFile("http://<hostname>:<http-port>/<context-root fo your web app>/crossdomain.xml");
The code will work like a charm.
Hope this helps everyone.
Thanks guys.
Best Regards, Gagan.

License migration from Flex Builder 3 to Flex Builder 4

I am ready to purchase a license for Flex Builder but am hesitant to do so. It appears that Flex Builder 3 is available now with Flex Builder 4 coming within some time period. If I buy a Flex Builder 3 license now will I be entitled to Flex Builder 4? If not, should I wait for FB 4 to become available? What is the anticipated ship date of that product?
Neil

From our FAQ
Q: If I purchase Flex Builder 3, am I eligible for an upgrade to Flash Builder 4?
A: Adobe has not yet announced the ship date of Flash Builder 4. To be eligible for a free of charge upgrade to Flash Builder 4, you will need to purchase maintenance along with your purchase of Flex Builder. You can purchase maintenance with your Flex Builder 3 Standard purchase for an additional $99 US which makes you eligible for a free-of-charge copy of Flash Builder 4 Standard edition when it ships. You can purchase maintenance with your Flex Builder 3 Pro purchase for an additional $299 US. To purchase maintenance, you will need to buy through an Adobe reseller. In the US, please contact CDW at 800-800-4239.

Execute batch command from flex builder

When I click the "Run" button in Flex builder 3, I would like to execute a batch file. It seems like in the Run settings, it only likes html and flash files. Other file types open in a flash environment Anyone know of a workaround?

Have a look at External Tools and see if that does what you want.
On the main menu bar in Flex Builder there's an "External Tools" icon, click its arrow and select -> Open External Tools Dialog..
Or from the menu, select "Run" -> "External Tools" -> "Open External Tools Dialog..."
You can add a new configuration there and do all kinds of stuff (like creating docs using ASDoc, etc..)

AIR apps won't launch from flex builder

Hi,
I am currently working on my first AIR app inside of Flex
Builder 3. For some reason, when I try to launch, profile, or debug
the app, it does it's normal "Loading.." message in the
bottom-right corner, but will never launch. The loading message
just disappears and the app never shows up. I do have the AIR
runtime installed. I receive this message when trying to profile
the application:
Process terminated without establishing connection to
debugger.
Command:
"C:\Program Files\Adobe\Flex Builder
3\sdks\3.0.0\bin\adl.exe" "C:\Personal\Freelance
Projects\MyBoatData_Prototype\bin-debug\MyBoatData-app.xml"
"C:\Personal\Freelance Projects\MyBoatData_Prototype\bin-debug"
Output from command:
invocation forwarded to primary instance
Can anyone help?

If you are using mx:Application, you need to set visible as
true in the app.xml file.
Also make sure that no instance of adl is already running. If
so kill that instance via task manager.
Thanks,
Gaurav

Upgrade From CS5 To CS6 Problems With Flash Graphics?

Hi People.
I upgraded from Adobe CS5 to CS6. I originally built a printable book and developed an interactive version in InDesign CS5, which I finally exported to Flash. For the printed version I used Adobe illustrator to create the book images and for the interactive version I converted the images into SWF.
The upgrade from Adobe CS5 to CS6 went well for the InDesign printed version of the book and I exported the new CS6 version of the printed book to PDF. However when I opened the old InDesign CS5 interactive version of the book in InDesign CS6 I was missing the links for the images.
When I tried to relink the images I was told `Cannot place this file. No filter found for requested operation:.
Please please help me because I am 2000 images in the new CS6 interactive version and short of going back and replacing each one individually, I am at a loss.
Thanks.

Steve,
Thanks...
Yes I can place the old SWF file into a new CS6 document and that works well, but I`m talking about 3 books of a total of nearly 10,00 images, which is a lot of time of replacing old for new,
Maybe I`ll stick with the interactive books staying in CS5 because I can`t see any material benefit of upgrading them to CS6, unless they were to be EPuped from their present CD Rom format?
However I do think it is a dreadfull oversight of Adobe not to stop me be penalized in a large slice of my profession, interactive second language book production, for the good intent of upgrading my CS Master Suite,
Take Care.

Upgrade from Flex 1 to 2

Hello.
I have an 'old' Flex 1.0 / 1.5 app that I want to upgrade to
2.0 and keep maintaining.
1) Is there an upgrade utility / script from Flex 1.0 / 1.5
to 2.x ?
2) What is the parallel of this entry:
mx:Image height="45"
source="@Embed('resources/login_appname.png')"
backgroundImage="@Embed('resources/gui/top_bg.gif')" width="450"
(emphasis on the 'bacjkgroundImage' attribute that seens to
have disappeared)
Thanks!

We don't have a tool to automatically modify an app to move
it to Flex 2.0. Check the Flex Support Center; we might still have
a tech note on things to look out for.
The Image component doesn't support a background image. Put
the Image inside of a Container, like Canvas, which does support
that.

You might have the ADL open already and had a bug, so it's
not going to show the new application.
You need to manually close ADL first before you try debugging
another time. If you're on a PC, use Task Manager ->
Processes... and end ADL.EXE
Then try running the app again... it should sort it
out.
