PDK SimObject Manager failes to load a simobject with a category ID

[redouane_bpw]

Hello all
i made a DLL that loads a dummy object
my sim.cfg contains the GUID of the simobjectV400 class and i succeed registring the Factory, however when i create the object using the Simobject manager->createObject(ID, "TITLE"); it fails

i tried to create an object that doesn't have a category ID (no DLL controller) to test, and it succeeded, but with my Class it doesn't

Any thoughts? thnx in advance
