MapWshowLayer function not defined when using JAPI

I using the JavaScript API testing framework developed by Assefa and Bill.  I
migrated the CWC2 version to Chameleon 1.1  The testing framework is into the
cvs under "chameleon/test_suite/js_testing/predefined_tests".

I'm using the chameleon demo in which I modified the "index.phtml" file to be
able to take a map file and a template as argument.  There is a copy of this
"index.phtml" file into the cvs under
chameleon/test_suite/unit_tests/php_tests/templates.

I added two lines into the "sample.html" to load the JavaScript API. I got the
JSAPI testing framework accessible through the web by creating a symbolic link.

Steps to reproduce:

1. Access the "main.phtml" file into the browser.
2. Set the application path to   
   /path/to/chameleon_sample/htdocs/index.phtml
3. Set the template path to /path/to/chameleon_sample/htdocs/sample.html
4. Set the map file path to /path/to/chameleon_sample/map/chameleon.map
5. Select the "layerSetStatus" predefined test
6. Click on "execute"
7. The error appears into the JavaScript console.

I'm working on Redhat 7.2, chameleon-1.1_20031110 from the cvs, MapServer 4.0

Here is the JavaScript consol error message:
