Problem with CFX_API_DOC_GEN_OBJECT_CHANGE

Hi,

i try to use the function module CFX_API_DOC_GEN_OBJECT_CHANGE. I have created an generic object (with bsp ui). I can read it with CFX_API_DOC_GEN_OBJECT_READ but when i try to change funtion it return FAULTCODE cFolders:Client.ObjectNotExisting.Is there any presuppositions to use this funtion module?

Kind regards,

Boguslaw
