[Chameleon] Re: Chameleon 2.0 LayerManager widget

[Paul Spencer]

Steven,

a couple of things could be going wrong here:

1. it looks like a path concatenation error may be occurring.  It should 
probably be putting a / between data and http.  Try adding a trailing / 
to your data path, or setting an absolute path.

2. the code may be trying to use the php-based XML parser to parse the 
capabilities document.  This parser is no longer supported and likely 
broken.  If you haven't already, you need to run 'make' in the 
chameleon/htdocs/common/wmsparse directory and make sure that your 
chameleon.xml contains the right path to the resulting executable in the 
appropriate element (wmsparse_path or something like that).

Let me know if this doesn't work (or if you have already tried this).

Cheers,

Paul
