[Mapserver-users] Mapserver 4.2.0 Template Weirdness

[Dirk Jesko]

Hi Marcus,

I might have an explanation. It seems to be a bug with the linux version.
The windows binaries work just fine.
 
I had the same problem with [layers] today. If &layers=layer1+layer2+layer3
is passed to mapserver, all layers are displayed, but only the last is
returned (layer3) to the [layers] variable in the template.

The reason seems to be the processLine function in maptemplate.c. The
snprintf function used to replace [layers] with the actual values does not
work the way it should (on linux systems). I replaced snprintf by strcat,
which works perfectly for me.

If you are familiar with C you can probably apply the fixes yourself and
rebuild mapserver. Otherwise, I can send you a modified maptemplate.c
tomorrow.


Regards,
Dirk Jesko
