Problems running custom components with Flex

[Loso]

Hi,

I'm trying to follow the tutorial in this PDF document (Chapter 2:Creating
Basic Components in Flash MX 2004):

[url]http://download.macromedia.com/pub/documentation/en/flex/15/flex_components_them[/url]
es.pdf


I'm using Flex 1.5 and Flash 8 IDE

For some reason and although I followed the authors instructions Flex fails
recognizing my new component:

The following code:

<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml" xmlns="*">
<greensquare/>
</mx:Application>

Returns:

1 Error found.

Error /main.mxml:3
Don't know how to parse element "*:greensquare". It is not a known type or a
property of mx.core.Application.

I followed the author's troubleshooting comments regarding this error message:

This means that the compiler could not find the SWC file, or the contents of
the SWC file did not list the component. The MXML tag must match the symbolName
for the component. Also, ensure that the SWC file is in a directory that Flex
searches, and ensure that your xmlns property is pointing to the right place.
Try moving the SWC file to the same directory as the MXML file and setting the
namespace to "*" as the following example shows: <mx:Application
xmlns:mx="http://www.macromedia.com/2003/mxml" xmlns="*">

Checked and rechecked but could not find the problem.

Any ideas?

Thanks in advance,
Loso.

I found the problem; I'd like to post it here because I think other developers
might equator this?

The first tutorial in this article did not work for me (F8 and Flex1.5), the
sample did work when I placed the component class in a package.
