[Chameleon] Trying to get Chameleon Installed - round 2

[woodbri@swoodbridge.com]

Hi all,

I'm trying to get Chameleon installed and grabbed the latest tar 
files from maptools.org. Running RH8.0, PHP-4.3.2-rc2, MS 4.0 
(probably pre-release).

I have narrowed down my problems with the sample applications to the 
following two:

1) I get a Server 500 error that is being caused by the Scalebar 
widget. If i change the cwc2 tag to cwc3 on the scalebar widget the 
page loads fine without the scalebar, but leave it as cwc2 and it 
dies.

2) I can not get the key map to display. I thought it might be a path 
problem so I set the IMAGE= tag to the absolute web path (not file 
system path), but that didn't work. and when I look at the page 
source it is calling drawmap.php to generate the image which seems 
strange if you are passing an image location.

A couple of other comments on installing the chameleon that are 
probably just the fact that I didn't read all of the docs on 
installing it, but I think you should clean these up anyway to make 
it more user friendly:

1) you have a lot of hard coded paths in the code and the sample app, 
just grep for ms4w. I think I found occurrences in the map file, 
index.phtml, session.php

2) you also have assumptions that the sample images are located at 
/chameleon_demo/images but the sample untar's into 
chameleon_sample/htdocs/images which does not have to be at the users 
web root as is my case.

I would recommend moving these definitions into one file that you can 
tell the user to edit as part of the install process.

So I got farther than last time, and any suggestions on debugging the 
Scalebar issue would be appreciated.

Thanks for providing a very cool product,
