I am sorry for my english . I do rope as follows:

    for (int i = 0; i <= numRope; i++) {
          auto spRope = Sprite::create("rope.png");
          spRope ->setAnchorPoint(Vec2(1, 0.5f));
          auto _ropePhysicsBody = PhysicsBody::createEdgeBox(spRope->getContentSize(), PHYSICSBODY_MATERIAL_DEFAULT, 3);
          spRope->setPhysicsBody(_ropePhysicsBody);
          std::string name = "Rope"+to_string(i);
          spRope->setName(name);

    if (i == 0) {
        spRope->setPosition(visibleSize.width/2, plankSpriteUp->getPosition().y);
        PhysicsJointDistance* RopeJoint = PhysicsJointDistance::construct(egeBodyUp, spRope->getPhysicsBody(), Vec2(1,1), Point::ZERO);
        sceneWorld->addJoint(RopeJoint);
    }else{
        std::string namePrev = "Rope"+to_string(i-1);
        spRope->setPosition(visibleSize.width / 2, this->getChildByName(namePrev)->getPosition().y- this->getChildByName(namePrev)->getContentSize().height);   
        PhysicsJointDistance* RopeJoint = PhysicsJointDistance::construct(this->getChildByName(namePrev)->getPhysicsBody(), spRope->getPhysicsBody(), Point::ZERO, Point::ZERO);
        sceneWorld->addJoint(RopeJoint);            
    }
    this->addChild(spRope);
    _sprites.push_back(spRope); 
}

when i run debuging, i getting error: Expression rotationZX == rotationZY CCNode.ccp line 293:

float Node::getRotation() const
{
    CCASSERT(_rotationZ_X == _rotationZ_Y, "CCNode#rotation. RotationX != RotationY. Don't know which one to return");
    return _rotationZ_X;
}
