Problem with child tag - Could not resolve x to a component implementation.

Question

Hello.
I am writing some chart component and got a problem setting property via child tag. Property is a custom class.
My directory structure:
Makefile  oxcharts  Session.vim  stats.as  stats.mxml  stats.swf
./oxcharts:
ColumnChart.as MyTest.as
stats.mxml:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:oxcharts="oxcharts.*">
    <oxcharts:ColumnChart id="myChart" showDataTips="true" width="600" height="310">
        <oxcharts:test x="5"></oxcharts:test>
     </oxcharts:ColumnChart>
</mx:Application>
ColumnChart.as:
package oxcharts {
    public class ColumnChart extends UIComponent {
        public var test:MyTest;
MyTest.as:
package oxcharts {
    public class MyTest {
        public var x:Number;
I got this error:
Error: Could not resolve <oxcharts:test> to a component implementation.
I guess something wrong with imports. Setting Number property via child tag works just fine.

I'm gonna give a clerear example, I hope it'll help you better understand what I mean let's say I have a custom class named Login:
package ec
         [Bindable]
     public class Login
          public var ID:int;
          public var Role:String;         
          public function Login()
And I need to use this class within MyAmazingCanvas, so my main app will be like this:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:oxcharts="ec.*">
     <mx:Script>
          <![CDATA[
               import ec.Login;
               [Bindable]
               private var myLoginStatus:Login=new Login();
               private function setLoginData():void{
                    myLoginStatus.ID=myID.text
                    myLoginStatus.Role=myRole.text;
          ]]>
     </mx:Script>
     <oxcharts:MyAmazingCanvas id="myCustomComp" myPublicNumber="323" LoginStatus="{myLoginStatus}" />
     <mx:TextInput id="myID" />
     <mx:TextInput id="myRole" />
     <mx:Button id="setData" label="Set Data" click="setLoginData()" />
</mx:Application>
When I said at the top level I meant outside the scope of any function, altough is not a requierement, you can as well set it at a function level.
