[flexcoders] reading arrays from Java into a chart

[netdeep]

Does anyone know the best practice for transferring data from a database to 
generate a 
flex chart?

I have a Java class Axis with these variables:

        String ID;
        Date start;
        Date end;
        int min;
        int max;
        int incr;
        String title;
        String signal;
        String type;
        List data;

And the List is an array of points defined in a class called DataPoint:

        public Date point1;
        public long point2;

I pass an array of Axis objects to the Flex app and try to convert it to an 
actionscript 
object:

package factory.data {
    [Bindable]
    [RemoteClass(alias="factory.data.Axis")]
    public class AxisObject {
        
        public var ID:String;
        public var start:Date;
        public var end:Date;
        public var min:int;
        public var max:int;
        public var incr:int;
        public var title:String;
        public var signal:String;   
        public var type:String;
        public var data:Array;
}

and I can access the title for example, but cannot get the DataPoint array into 
the chart.  
Furthermore, when I debug it gives me the following errors:

ReferenceError: Error #1056: Cannot create property endDate on 
factory.data.AxisObject.
ReferenceError: Error #1056: Cannot create property dataList on 
factory.data.AxisObject.

Thanks for any help you can offer.
