Problems: Change Flex 3 Project to Flex 4

[juwu]

Hi

I try to change my old Flex 3.5 Project to a Flex 4 Project.

Infos to my Project:
Backend: Java Based
Frontend: Flex Project
Spring Source includes the Flex Builder Licence

I changed the sdk in spring source:
Window > Preferences > Installed Flex SDKs

I changed the flex sdk reference in the file:
project.properties >> FLEX_HOME

I changed in all mxml files the flex libs to followings:
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"

I removed all old css styles.


problems:

Spring Source has problems to identify the fx tags.

e.g. the code within <fx:Script></fx:Script> is just only black no highlights.

when I try to bind a variable, which is defined in the script area, will not detect in the Label.

also Error message in Spring Source:
Description Resource Path Location Type
„C:\Program Files\springsource\flex_sdk_4.1.0.16032\frameworks \libs\player\9.0\playerglobal.swc“ konnte nicht geöffnet werden GraphicalETL Unknown Flex Problem


while runtime my project has also problems to fill the Labels:
ERROR:
ReferenceError: Error #1069: Property languageLocator not found on GraphicalETL.view.mainscreens.LoginScreen and there is no default value.

Source:

<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:fx="http://ns.adobe.com/mxml/2009"

private var languageLocator:LanguageLocator;

/**

...}

</fx:Script>

<s:Panel verticalCenter="0" horizontalCenter="0"

<mx:Form>
<mx:FormItem width="100%" label="{languageLocator.currentLanguageXML.loginSc reen.user.text().toString()}" required="true" tabIndex="1">

I've done this a couple of times without a problem (other than the IDE not being totally stable) on Snow Leopard.

Did you start from an STS version of the IDE? Do you have the Flash Builder 4 plugin in your dropins folder? What O/S are you on?

You should be able to change the sdk version directly from within the IDE. You also have the <![CDATA[ ] block within <fx:Script>, yes?

If all else fails, you might also want to try creating a new Flash Builder project and copying the files from your old project into it.

Hi

thank you for your reply!!

SpringSource is running on Win XP installed in a virtual machine (vmware fusion) and this is running on the current version of OSX.

"Did you start from an STS version of the IDE? "
What does STS mean??

"Do you have the Flash Builder 4 plugin in your dropins folder? "
Hmmm no I´m using the old Flex Builder version.
How could I deinstall the flex builder version and install the new flash builder 4 version?
that will be the first thing I have to change now....

"You should be able to change the sdk version directly from within the IDE. "
You mean that I have to change just only the sdk in the preference panel??
Window > Preferences > Installed Flex SDKs
And not also in the properties file??
project.properties >> FLEX_HOME

"You also have the <![CDATA[ ] block within <fx:Script>, yes?"
YES.

"If all else fails, you might also want to try creating a new Flash Builder project and copying the files from your old project into it."
I created an new dummy project and the application class look like this:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
</mx:Application>

nothing changed!!

also when I create new mxml components it creates a component with the old style and libriaries.

Hi Julia,

STS is SpringsourceToolSuite. Since I also do java development on the back end, I find it more convenient than trying to mod Flash Builder.

I think you will probably need Flash Builder or the Flash Builder plugin in order to use the Flex 4 features.

Hi Slidewayz

I managed the change from Flex 3 to Flex 4.
thanks for your advices, which gave me the points I had to look for.
the main point was to change the flex builder 3 licence to flash builder 4 licence.

Now I have other problems....

for the change from Flex 3 to Flex 4 I changed a lot of classes, cause the flash builder showed me a lot off errors and warnings.

Flash Builder want me to change also the package names.
And after that I have problems to compile my project.

Problem:

Spring Source Toolkit/Flash Builder 4 shows a lot of errors, e.g.:
<views:MyComponent> Couldn´t solved as component implementation (translated from german).

Ant Build (Backend >> build.xml):
Compiling Successfull!!!

Problem:

Spring Source Toolkit/Flash Builder 4:
Without errors

Ant Build (Backend >> build.xml) shows a lot of errors, e.g.:
<views:MyComponent> Couldn´t solved as component implementation (translated from german).
Compiling FAILED!!!
