Hi, I'm trying to copy a message tree by changing the namespace, to do this I use a recursive function that works, until I try to go to the next sibling of the father , when the OutputReference loose the syncrony and start creating child in bad places.

This is the code im using for:
Code:

CREATE PROCEDURE navigate (IN root REFERENCE, INOUT Output REFERENCE)
BEGIN
   
   DECLARE cursor REFERENCE TO root;
   DECLARE cursorOut REFERENCE TO Output;

   MOVE cursor FIRSTCHILD;
   IF LASTMOVE(cursor) THEN
      CREATE FIRSTCHILD OF cursorOut NAMESPACE nsT NAME FIELDNAME(cursor) VALUE FIELDVALUE(cursor);
   MOVE cursorOut FIRSTCHILD;
   ELSE
      MOVE cursor NEXTSIBLING;
      
      IF LASTMOVE(cursor) THEN
         CREATE NEXTSIBLING OF cursorOut NAMESPACE nsT NAME FIELDNAME(cursor) VALUE FIELDVALUE(cursor);
      END IF;
      MOVE cursorOut NEXTSIBLING;   
   END IF;

   WHILE LASTMOVE(cursor) DO
   
      CALL navigate(cursor, cursorOut);
      MOVE cursor NEXTSIBLING;
      MOVE cursorOut PARENT;
   END WHILE;
END;


Thanks!
