这个默认值怎么设置？

ssht968 · 发表于 2014-3-14 16:02:18

我修改了DictSelectTag.java 增加了为空判断就好了

Boolean checked = false;
if(!"".equals(this.defaultVal)&&null!=this.defaultVal){
String[] values = this.defaultVal.split(",");

for (int i = 0; i < values.length; i++) {
String value = values[i];
if (code.equals(value)) {
checked = true;
break;
}
checked = false;
}
}

if(StringUtil.isNotEmpty(this.defaultVal)){
  String[] values = this.defaultVal.split(",");

                     for (int i = 0; i < values.length; i++) {
                              String value = values[i];
                              if (code.equals(value)) {
                                    checked = true;
                                    break;
                              }
                              checked = false;
               }
            }

是不是因为字典表里面用于编码显示文本显示的数据字段是空的
