Upgrading a model from 24.0 to 24.2 beta changes the A* grid size

Open the attached model astar-240.fsm in 24.0. This is how the A* grid grid looks like:

Open the same model in 24.2 beta. This is how the A* grid grid looks like:

Upgrading a model from 24.0 to 24.2 should not change the grid size.

Could you please fix it before the final release ?

Thanks for the bug report. It looks like this issue has been fixed, and should not be a problem in the final release.

Hi @Jordan Johnson , could you please check if this bug has been fully fixed ?

I have a weird behaviour with the attached model astar-242.fsm.

When you open the model in 24.2, the grid bounds are around the source and the sink:

But when you hit reset the grid bounds change:

I notice the same behaviour in 25.0.0: astar-250.fsm

This is a variable binding issue with the grid forgetting that the user had customized its size. The grid is automatically resizing itself to fit its members. We can fix the binding issue for an upcoming bugfix release.

To work around the issue in the meantime, you could add members (the source and sink objects in this example, or barriers beyond them) to grow the grid's size automatically on reset rather than manually resizing it.

Hmm, this seems like a different issue. I see the same behavior with the given model. I'll add this to the dev list to investigate further.
