Hi again,
when Read(GeListNode* node, HyperFile* hf, LONG level){}
is called I load my plugin params, then I try to get a reference to my polygon object like this:

  
{  
          BaseObject *op = (BaseObject* )node;  
          BaseContainer *data = op->GetDataInstance();  
          if ( BaseObject* linkOp = data->GetObjectLink(INSTANCEOBJECT_LINK, op->GetDocument()) ) {  
               polygonObjectRef = (PolygonObject* ) linkOp;  
          }  
     }  

that works fine when I receive message MSG_MENUPREPARE or message type 1001090 which I have no idea what it is.

so the question is which message type should I check for to get my references after I open the file?
Is there any message sent to ObjectData after I read the file?

thanks

The problem with doing this type of thing in Read() is that it is possible (probable even) that the reference has not been resolved as the file is still being read (the linked object may not exist yet).

For this, listen for MSG_MULTI_DOCUMENTIMPORTED in ObjectData::Message(). This signals that the document has been loaded - completely.
