[maplab-users] PROCESSING directive produces parsing errors in Mapbrowser (Maplab 2.1-RC1)

[Jeff Hamm]

 For a given map file, using PROCESSING "BANDS=5,4,3" directive causes
the following error:

        Warning: [MapServer Error]: getString(): Parsing error near
(END):(line 192) in
        /maplab21/htdocs/common/wrapper/map_session.php on line 215

Under Maplab/MapBrowser, no map output is generated (just the error).
Under Chameleon 1.1, the waitimage remains active indefinitely (no image
produced). Commenting out the PROCESSING directive allows the map to be
rendered (under Mapbrowser, or Chameleon).

Incidentally, GMapFactory will produce the correct multiband image when
using the PROCESSING "BANDS=5,4,3" directive (using the same map file).
So I know that my mapfile/mapserver configuration is capable of
producing the desired output. The Maplab(MapEdit) XML template is
maplab_40.xml.

I've checked logs etc. for more detail, but to no avail. The parsed
mapfile created in the /tmp directory DOES contain the PROCESSING
Directive string (when not commented out in the source mapfile), but
there is an extra 'END' inserted after 'PROCESSING' , which effectively
truncates the mapfile. I'm not certain that the problem lies in the
parsing, but somewhere along the line, this directive gets lost.

Can anyone tell me if this is a GDAL version/multicopy problem, or a PNG
driver problem (possibly related to Mapserver bug 397 - Color problems
when using raster symbols and 8 bits PNG) ??

TIA for any help.
