以下是代码码，哪里有问题
public static Table createInv_trans_head(Table table,String concept,Map<String, String> defaultValues,String k){
                System.out.println(BizUtils.createNextSequenceString(k,"000"));
                String a=BizUtils.createNextSequenceString(k,"000");
                defaultValues.put("bill", a);
                return BizData.create(table,concept, defaultValues, k);
        }

Caused by: java.lang.NullPointerException
        at Kcgl.createInv_trans_head(Kcgl.java:15)
java调试看一下，报的是空指针异常

是这样，我的需求是：
根据前端送的参数决定新建字段“bill”(单号)的流水号前缀，k是前端参数，现在不知道后端怎么赋给“bill” 默认值

jishuang

这样的应该是在保存的时候做的吧，新增的时候前端怎么传的参数？

Model.prototype.bizData1NewCreateParam = function(event){
          
          var k='cg'+ justep.Date.toString(new Date(), 'yyMMdd');
          alert(k);
          //var param = new biz.Request.ActionParam();
      
      event.param.setString("k", k);
        };

因为要根据出入库类型的不同，决定前缀不同

没有新增怎么就保存，好奇怪

jishuang

那应该自己定义一个action，在action中判断传的参数，然后设置
在data的新增前事件中去调用action
