[maplab-users] symbol picker

[Jean-Baptiste RICHARD]

hello,
i'm a new user with maplab and when i want to change a symbol for a
class layer, i've got this message:

Fatal error: Property 'symbol' does not exist in this object. in
c:\appserv\www\maplab\htdocs\common\picker\symbol_picker.php on line 174

The fonction overlay symbol is ok and i don't understant what's wrong
with my configuration.

Thanks for help,

RICHARD Jean-baptiste
