NodeData plugins can only be stored in SceneHooks. So you have to write your own SceneHook to save your list of NodeData plugins along with the document.

FYI, I put together a small example of how to store a NodeData plugin within a scene hook.

Please check the code comments for more detailed information.

the NodeData plugin:

  
#include "c4d.h"  
#include "c4d_symbols.h"  
  
  
//just a extremly simple Nodedata plugin :)  
  
class MyNode : public NodeData  
{  
  public:  
      static NodeData *Alloc(void) { return gNew MyNode; }  
};  
  
  
#define ID_MYNODE 1024726  
  
Bool RegisterMyNode(void)  
{  
  return RegisterNodePlugin(ID_MYNODE, "My Node", 0, MyNode::Alloc, NULL, 0, NULL);  
}

the SceneHookData plugin to store the NodeData plugin:

  
#include "c4d.h"  
#include "c4d_symbols.h"  
  
  
class MyNode;  
  
#define ID_MYSCENEHOOK 1025181  
  
  
class MySceneHook : public SceneHookData  
{  
  public:  
      //constructor; initialization and plugin node allocation  
      MySceneHook()  
      {  
          hookname = String("My SceneHook Name");  
          mynode = (BaseList2D* )AllocListNode(1024726);  
      }  
  
      virtual Bool Init(GeListNode *node);  
      virtual Bool Read(GeListNode *node, HyperFile *hf, LONG level);  
      virtual Bool Write(GeListNode *node, HyperFile *hf);  
      virtual LONG GetBranchInfo(GeListNode* node, BranchInfo* info, LONG max, ULONG flags);  
  
      static NodeData *Alloc(void) { return gNew MySceneHook; }  
  
  private:  
      AutoAlloc<GeListHead> head;        //this is the list head were the plugin node will be inserted to  
      String hookname;  
      BaseList2D *mynode;        //pointer to an instance of the plugin node  
};  
  
Bool MySceneHook::Init(GeListNode *node)  
{  
  if (!head || !mynode) return FALSE;  
  
  head->SetParent(node);        //needed to save the node list  
  
  head->Insert(mynode, NULL, NULL);    //insert the plugin node into the list  
  
  return TRUE;  
}  
  
Bool MySceneHook::Read(GeListNode *node, HyperFile *hf, LONG level)  
{  
  return head->ReadObject(hf, TRUE);    //needed to read files  
}  
  
Bool MySceneHook::Write(GeListNode *node, HyperFile *hf)  
{  
  return head->WriteObject(hf);    //needed to save files  
}  
  
LONG MySceneHook::GetBranchInfo(GeListNode *node, BranchInfo *info, LONG max, ULONG flags)  
{  
  //fill the info structure array; only one element is saved in this example  
  
  info[0].head = head;  
  info[0].name = &hookname;  
  info[0].id = ID_MYSCENEHOOK;  
  info[0].flags = 0;  
  
  return 1;    //return the number of filled BranchInfo elements  
}  
  
  
  
Bool RegisterMySceneHook(void)  
{  
  return RegisterSceneHookPlugin(ID_MYSCENEHOOK, "My SceneHook", 0, MySceneHook::Alloc, EXECUTION_EXPRESSION, 0, NULL);  
}

main.cpp

  
...  
Bool RegisterMyNode(void);  
Bool RegisterMySceneHook(void);  
...  
  
Bool PluginStart(void)  
{  
...  
  if (!RegisterMyNode()) return FALSE;  
  if (!RegisterMySceneHook()) return FALSE;  
...  
  return TRUE;  
}

hope this helps

cheers,
Matthias
