Hibernate问题

[大明哥_]

做的SSH项目，开始的时候毫无问题，但是今天在进行Compass整合的时候，重新运行该段代码的时候就出现异常错误。
2012-11-12 19:32:20 an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session)
org.hibernate.AssertionFailure: collection [com.paixie.domain.Brand.goods] was not processed by flush()
我主要是执行上面数量的修改：

public String finishedAdd(){
		//获取商品编号
		HttpServletRequest request = (HttpServletRequest) ActionContext.getContext().get(ServletActionContext.HTTP_REQUEST);
		String goodsId = request.getParameter("goodsId");
		//根据商品编号获取商品实例
		GoodsListing goodsListing = goodsService.getGoodsById(goodsId);
		//获取该商品编号的所有详细信息
		List<GoodsDetail> goodsDetails = goodsDetailService.getAllGoodsDetailByGoodsId(goodsId);
		int goodsNumber = 0;
		for (int i = 0; i < goodsDetails.size(); i++) {
			GoodsDetail goodsDetail = goodsDetails.get(i);
			goodsNumber = goodsNumber+goodsDetail.getGoodsNumber();;
		}
		goodsListing.setGoodsExitNumber(goodsNumber);
		goodsService.updateGoods(goodsListing);
		ActionContext.getContext().put("message", "添加商品信息成功...");
		ActionContext.getContext().put("type", "goodsAddSuc");
		return "finishedAdd";
	}

求解.......

在执行updateGoods之前确保你的goodsListing被保存到数据库中！

肯定是已经保存在数据库里面的啦
