Rexster + OrientDB + BulbFlow - 500 error on get_all after delete

[unovongalixor]

I have a model (menu) and i'm using get_all to retreive a list of all of my menus from rexster. this works fine until I use the delete method to remove one of the nodes.

after the delete, get_all begins returning a 500 error. I dug into Rexster to see what's happening and it's giving me a NullPointerException:
