If you do a save("TestBis.xml") in the script, AFTER Sphere.dynamic=True you will observe (l.88 of the .xml normally) that, indeed, the body is saved as non-dynamic
Whether first load/save lines were commented.

So :
- if you create your sphere as non-dynamic
- then update it as dynamic (without any load/save at the moment)
- the sphere will indeed behave as dynamic, even if .xml saves done after will pretend the contrary...

b.dynamic and b->isDynamic() out of synchro in case of save/load

Status in Yet Another Dynamic Engine: New

Bug description:
The attached script will illustrate the title.

It is about a sphere which is created as dynamic=False, then updated to dynamic=True, in order to let rotate it with NewtonIntegrator. 

Directly with the script as it is joined, you will observe that the orientation of the sphere is unfortunately not at all modified.

But, "hokus pokus", (magic expression) comment l.27-28 about the save/load, re-run and you will have the orientation which evolves...

The reason is in b->isDynamic() (in C++). In the first case (with save/load), you will have b->isDynamic()=0 (in C++), even if b.dynamic=True (in python)
Whereas, in the second case, things are as they should : b->isDynamic() = b.dynamic = True

You can easily check this with logs from NewtonIntegrator.cpp (I could not attach the file with cout typed I used : no more than one attachment it seems)
