gridselect 组件无法清空

southpine

很少苦恼，搞了好长时间，也没搞定。

jishuang

之前的版本可以输入，V3.2.1版本中不能输入，直接选择，选择后要清除数据，可以给下拉添加一个空值
如下：

southpine

按照你的做法：
Model.prototype.unitDataAfterRefresh = function(event){
    this.comp('unitData').newData({
         'index': 0,
               'defaultValues': [{
                     fUnit: ''
                }]
         });
    };


报错如下：

"concept":"fUnit"
你的概念是fUnit？

southpine

概念是 BA_items， fUnit是一个关系，我想获取概念中的唯一值（商品单位）。

jishuang

从保存的地方看应该是queryAction中设置的不对
rowsConfig":{"concept":"fUnit","sequence":"fUnit"}

southpine

queryAction设置截图：

southpine

系统生成的ksql源码

应该是设置了distinct后新增的问题，设置了列的distinct就不能新增

要清空gridSelect选择的数据，可以在后面放一个按钮，清除数据，然后调用data的setValue
如下： var mainData = this.comp("mainData");
       mainData.setValue("fName", "");




现在的V3.2.1版本可以不用写代码。gridSelect上有个clearButton属性设置为true，在gridSelect中就会显示一个小红叉可以清除数据

southpine

我这种情况只能使用distinct，取得物品单位，应该怎么办。必须能输入新值。
