There are three things that jump out.

If this component is in another SWC file, make sure to reference it in the project settings
Import the namespace or call it directly (com.whatever.namespace.Warning)
Make sure to call new to generate a new object. In your code above, warningMessage is null.

private var warningMessage:Warning = new Warning();

+1. Also, "4. Don't write code in MXML Script section without function - it gets executed as if it was in class constructor, which is too early to manipulate controls - they're not created yet." – alxx May 12 '11 at 05:51

Make sure that you have imported your custom component to the file you are using it.

You will need to reference the other custom component as a mxml namespace.

Check the following article to get an accurate illustration: http://www.roseindia.net/flex/custom-mxml-tags.shtml
