Flex 4.5 (Hero) Login Example for Mobile

[masuland]

Hi there,

I am trying to create a Flex 4.5 (Hero) Login Example for Mobile devices, see:

http://code.google.com/p/masuland/wiki/LoginExample or
http://code.google.com/p/masuland/wi...MVCpshCtl_PInj

When running the application I am getting this error:

VerifyError: Error #1014: Class mx.modules::Module could not be found.

The source code can be found in the SVN of Google Code:

Any ideas?

The FlexXMLApplicationCOntext has a dependency on the Flex mx.modules.Module class which isn't available in the mobile SDK. We're planning to remove this dependency in future version of SpringAS.
For now the only workaround is to use the XMLApplicationContext.

Hope that helps,

cheers,

Roland

Thanks Roland,

just tried your quick fix ... I have switched FlexXMLApplicationContext to XMLApplicationContext:

        public var applicationContext:XMLApplicationContext; 

... and added the FlexStageDefaultObjectSelector class because it was needed:

        // Force inclusion of classes not referenced elsewhere in the code
        {
            AppController, 
            AppMockDelegate, 
            FlexStageDefaultObjectSelector,
            EventHandlerMetadataProcessor, 
            DefaultAutowiringStageProcessor, 
            RouteEventsMetaDataProcessor
        } 

Now I am getting another error:

Error: Can't autowire property by name: Unsatisfied dependency in object [settingsBoxCP] for property [currentLocale]

For some reason the property injection seems to be broken now:

        [Inject(name='appModel', property='currentLocale')]
        [Bindable]
        public function get currentLocale():LocaleVO
        {
            return _currentLocale;
        }
        
        public function set currentLocale(value:LocaleVO):void
        {
            _currentLocale = value;
            
            _isCurrentLocaleDirty = true;
            invalidateProperties();
        } 

... see SettingsBoxCP.as file in the SVN:
http://masuland.googlecode.com/svn/t...ttingsBoxCP.as

Any ideas how to fix that?

Hey there,

there is a known issue with external property files and metadata based injections, are you using multiple property files perhaps?
There is a forum post here somewhere that describes the same problem.
Normal injections will work fine, but injecting external properties sometimes fail. I'll try and look up the post.

cheers,

Roland

Hey Roland,

Maybe you mean that post "Context does not autowire external properties anymore" ... see:

http://forum.springsource.org/showth...bject+property

Not sure how this could help us!? Thanks for your help!

[masuland]

Hey there,

Flash Builder 4.5 has been released yesterday:

http://www.adobe.com/products/flash-builder.html

... which means we could use Spring AS for Mobile development. When do you think there will be an update of Spring AS available so that we can continue working with common Spring AS features like property injection ... see code:

[Autowired(name='ModelLocator', property='products')]
 public var products:ArrayCollection; 

[Inject(name='ModelLocator', property='productManager.products')]
 public var products:ArrayCollection; 

... and the Spring AS documentation section "2.1.2.17. Binding an object property to a property of an object in the container":

http://www.springactionscript.org/do..._the_container

Thanks and sorry for the rush,
masu

Hi there,

a version 1.2 is in the making, it might even be released as a v1.5, we're not sure yet. We are also in the process of preparing for v2.0 development.

Unfortunately all of our opensource activities are being done in our spare time, therefore it virtually impossible for us to give any kind of timeline on when things will be ready and released. We can't predict when family, work and life in general gets in the way of OS development.

I'm sorry I don't have a definitive answer for you.

cheers,

Roland

currently in version 1.1 with Flex 4.5 SDK,when you got the error "mx.modules::Module could not be found", please replace "import mx.modules.Module" to "import spark.modules.Module", then rebuild the lib, and be fine.

[masuland]

Hi there,

I have filed a bug for this issue:
https://jira.springsource.org/browse...ONSCRIPTAS-140

Thanks @NeoGuo ... I will give it a try!

I had the same issue, but it is not too hard to remove the mx.Module dependency from Spring AS, the compiled workaround can be found at http://www.igindo.com/springASMob.zip, you can then use SparkXMLApplicationContext.

Alternatively, there's no harm to include the mx package manually to your mobile project
