[Chameleon] Upgrade problems to MapServer 4.4.2

[Jason Grimes]

Here is an update on what I have found.  It looks to be a problem in the
PHP sessions.  Chameleon errors out when map_session_mode=1.  If I copy
the URL and change the map_session_mode to 0 it works. If I try and do
anything in the interface, like pan or activate a layer, the page does
not load at all and I get the following errors in the /tmp/php.log file:

[13-May-2005 14:24:37] PHP Warning:  [MapServer Error]:
loadOutputFormat(): Parsing error near (;):(line 13)
 in
/usr/local/chameleon/chameleon-2.1pr1-20050412/htdocs/common/wrapper/map_session.php on line 215
[13-May-2005 14:24:37] PHP Warning:  Failed to open map file

/usr/local/chameleon/chameleon-2.1pr1-20050412/htdocs/common/wrapper/map_session.php on line 215
[13-May-2005 14:24:38] PHP Fatal error:  Call to a member function on a
non-object in
/usr/local/chameleon/chameleon-2.1pr1-20050412/htdocs/widgets/KeyMapDHTML/KeyMapDHTML.widget.php on line 150

Any ideas?  I'm going to poke through the code and track down the
map_session_mode and see if there is a problem there.  I know that 1=R/W
session and 0=Read Only session.  Thanks,

Jason
