Hi, I've got a problem when closing Cinema. My tag plugin has to write some data when it is shut down. The folowing method is called inside the free()-method:

> \> \> void MoCap::SetBackIDs (){ \> \> BaseDocument \*doc = GetActiveDocument(); \> GePrint ("doc"); \> if (!doc->GetFirstObject()){ \> GePrint ("if"); \> return; \> } \> BaseObject \*op = doc->GetFirstObject(); \> GePrint ("op"); \> BaseObject \*current; \> GePrint ("current"); \> BaseContainer \*opContainer = op->GetDataInstance(); \> GePrint ("opContainer"); \> \> GePrint("MoCap::Free"); \> \> while (op!= NULL){ \> GePrint ("while"); \> opContainer = op->GetDataInstance(); \> opContainer->SetBool (DESC_USED, FALSE); \> opContainer->SetLong (DESC_JOINT_ID, 0); \> current = op->GetDown(); \> if (current == NULL) \> current = op->GetNext(); \> if (current == NULL) \> current = op->GetUp()->GetNext(); \> op = current; \> } \> \> GePrint ("End Free()"); \> } \> \>

This works fine. The problem is, when closing Cinema the document already seems empty when calling this free-method. The console prints out "doc", but doesn't get any further. Does someone have an idea?

Thanks

You shouldn't use GetActiveDocument() within a tag. You should use the document the node (tag) is attached to.

node->GetDocument()

The node is passed to the classes' methods

Free(GeListNode *node)

cheers,
Matthias
