graspit_simulator database planner cannot load grasps from household-objects database

Hi all,

I am using the graspit simulator downloaded from https://code.ros.org/svn/wg-ros-pkg/stacks/graspit_simulator/trunk with household-objects database.

When I was using the database planner, I couldn't load the grasps for the corresponding model. image description

I noticed that, in the household database(I am using householdobjects-0.4diamondbackprerelease2.backup), grasps were computed for WILLOWGRIPPER2010 and SHADOWHAND. But when I tried to "import Robot" in Graspit, it gave error when loading these two hand models. It was only successful on the original pr2gripper(pr2gripper.xml in the 'models/robots/pr2gripper' directory)

Any idea? thank you.
