Strange Behavior of KeplerianOrbit

[MaximeJ]

Hi @Echulion,

Your problem looks similar to the one in this post.
You may be missing an explicit cast to KeplerianOrbit here.

Quoting Petrus:

@petrus.hyvonen

Sometimes one needs to cast types in the python version of orekit, in this case it can be be done by:
orbit = KeplerianOrbit.cast_(orbit)

Does that solve your issue ?
