A* doesn't want to work

[mrchickenova]

Hi, I have a simple probability grid which I want to use as an occupancy grid with the Astar.m file.

Here is how I proceed
occupancy_grid = double(this.grid > 0.1);
as = Astar(occupancy_grid);
as.plan(goal);
as.query(start, 'animate');

But the animation doesnt work. When I replace Astar by Dstar, everything works fine. I also tried to use as.path(start) as suggested in the help but this doesn't work. I get an error that says that Navigation doesn't have any member function 'path'.
Is it a bug or am I doing something the wrong way?
