asset_nodeapi submit does not contain node ID

I have implemented asset with cck and views. When a new content type created (files) and then content of type files is created, the associated asset has its asset_node->nid set to 0. When debugging the code, asset_nodeapi is called with submit, and no node->nid exists at this time, so when created, it contains asset_nod->nid=0. Should this not be done on insert instead, when the node->nid actually contains a value?
