DataService with Flex

[Rafael_Viana]

Hello,

I'm testing the DataService with LCDS and I'm experiencing some problems.

I built an AIR application and it works fine.I used this same code to built a Flex application but when I compile the Flex app the player throws me an error:

ReferenceError: Error #1065: Variable mx.data::LocalStoreFactory is not defined.
    at mx.data::DataStore()[C:\depot\DataServices\trunk\frameworks\projects\data\src\mx\data\DataStore.as:219]

I didn't find in the Google some problem like this.Someone can help me?

How can I use the DataService with the Flex without errors?

Can you copy your code?

It looks as if your managed array is not actually created?

Are the classes which are defined in your app public, if not set the classes declaration to public and see if this resolves the issue.

Sounds like you are missing some library entries. Are you compiling using Flash Builder or mxmlc?

If you are using mxmlc, a good tip is to view the .actionScriptProperties file in the Flash Builder (Eclipse) project directory to see the compiler settings that FlashBuilder is using.

I'm using Ant to compile my combined Java/Flex LCDS app. The portion of the ant script to do the compilation is reproduced below - note the library-path settings (make sure all these are included to avoid the problem you are describing).

Hope this helps!
