Hi,

Suppose you have a ColumnChart with some ColumnSeries defined in MXML
like this:

<mx:ColumnChart>
  <mx:series>
    <mx:ColumnSeries xField="@cl" yField="@cmu">
      <mx:fill>
        <mx:SolidColor color="#e48701"/>
      </mx:fill>
    </mx:ColumnSeries>
  </mx:series>
</mx:ColumnChart>

This works perfectly fine. Now I want to change the ColumSeries to my
own MXML-component based on ColumSeries, lets call it MyColumSeries.
The new ColumnChart becomes like this:

<mx:ColumnChart>
  <mx:series>
    <bla:MyColumnSeries xField="@cl" yField="@cmu">
      <mx:fill>
        <mx:SolidColor color="#e48701"/>
      </mx:fill>
    </bla:MyColumnSeries>
  </mx:series>
</mx:ColumnChart>

Now I get the following compile error:
Could not resolve <mx:fill> to a component implementation.

Now I was under the impression that when you define an MXML component
it publicly derives from it's base-component, and therefor it should
work just like it's base-component plus anything you add/change.

Why do I get the error then?

Cheers,
