It sounds like you don't have the SWC with the comc.adobe.flex.extras.controls.* classes (which are not part of a standard Flex installation) or it isn't on your library-path.

I'm aware of package notation but I'm not sure how this works in this example and what is going wrong. In the code, I have within the Application tag, a namespace definition. So, the Application tag opens like this: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" xmlns:ec="com.adobe.flex.extras.controls.*"> I'm cutting out what is not relevant to the problem. The problem is that this tag is not recognized by Flex 3, it gives a compile time error: <ec:AutoComplete id="nameField" labelField="name" lookAhead="true" /> I guess I need to figure out what is inside the controls package that is named above in the Application. The error I get on that line is 1046: Type was not found or was not a Compile time constant: AutoComplete. How might I figure this out? The text where I found this does not elaborate on this particular code. It is an example of coding that is a little different then what I am familiar with. Can anyone help me make sense of this, please? Bruce
