SLD PIXMAP Error With How-To Example

[Jennifer Zeisloft]

Hello-

I have an update for this problem with using external graphics for SLD 
requests.

I attempted to use the SLD file at 
http://www2.dmsolutions.ca/msapps/world_testdata/tests/sld_tests/sld_polygon_fill_symbol_external.xml

with the ms4w-Chameleon OGC sample application (which contains the proper 
layer - WorldGen- for the SLD) and received the same error messages that 
I've been receiving with my own application:

*Warning*: [MapServer Error]: loadSymbol(): Symbol of type PIXMAP has no 
image data. in *C:\ms4w\apps\chameleon\htdocs\common\wrapper\map_session.php
* on line *215*

*Warning*: Failed to open map file /ms4w/tmp/sess_43264a06bd7bc/1126582974-
2202.map in *C:\ms4w\apps\chameleon\htdocs\common\wrapper\map_session.php*on
line
*215*

*Fatal error*: Call to a member function on a non-object in *
C:\ms4w\apps\chameleon\htdocs\widgets\KeyMapDHTML\KeyMapDHTML.widget.php* on 
line *150*


Could this be a bug?? Could there be a problem with the way ms4w is set up 
on our server (although we did nothing different this time...)? Is there a 
copy of this same sample application available through the MapServer website 
so that I could test the same application on a different server (if so, I 
haven't been able to find it)? This is a problem I just haven't made any 
headway on and any suggestions would be greatly appreciated!
