#136 More than one of the same device in stage doesn't work

[Michael Janssen]

Using more than one of the same device on the same
model doesn't work at all - the second and subsequent
devices are not instantiated.

blobtest.cfg:
driver
(
name "stage"
provides ["simulation:0"]
plugin "libstageplugin.so"
worldfile "blobtest.world"
)

# robot 0
driver(
name "stage"
provides ["6665:position:0" "6665:blobfinder:0"
"6665:blobfinder:1"]
model "p0"
)

blobtest.world:
# Desc: Stage demo with lots of models. Works with
everything.cfg.
# CVS: $Id: everything.world,v 1.36 2005/05/16 06:05:11

Thanks for the exemplary bug report, Michael. Patch tested and applied to
CVS HEAD. You're a bold man working out of CVS right now. It should
stabilize this weekend, with only cleaning up, fixes, and possibly grippers
and pucks, until release 2.0.0.
