CheckboxGroup 在使用Form的getFieldProps 会引起 Cannot read property 'indexOf' of undefined

[GitNiko]

版本: "1.0.0-beta.3"
如下例子

// in render()
const useTypeProps = getFieldProps('useType', {
            rules: [
                {  type: 'array',
                   required: true,
                   validator: this.checkUseType
                },
            ]
        });
return (
<Form form={this.props.form}>
<FormItem
             id="useType"
             label="用途："
             labelCol={{ span: 6 }}
             wrapperCol={{ span: 18 }}
             required
             >
             <CheckboxGroup options={[{value:1, label: '农机'},
               {value:2, label: '农资'}, {value:3, label: '土地租金'}, {value:9, label: '其他'}]}
               {...useTypeProps}
              />
</FormItem>
</Form>
)

看了源码实现

constructor(props) {
    super(props);
    let value;
     // 在getFieldProps后 这里value会undefined
    // 可以加一个check
    //   if (props.value === undefined || props.value === null) {
    //       value = '';
    //   } else {
    //       value = props.value;
    //   }
    if ('value' in props) {
      value = props.value;
    } else if ('defaultValue' in props) {
      value = props.defaultValue;
    }
    this.state = { value };
  }
render() {
    const options = this.getOptions();
    return (
      <div className="ant-checkbox-group">
        {
          options.map(option =>
            <Checkbox disabled={'disabled' in option ? option.disabled : this.props.disabled}
              // 这里会抛出 'indexOf' of undefined
              checked={this.state.value.indexOf(option.value) !== -1}
              onChange={() => this.toggleOption(option)}
              className="ant-checkbox-group-item" key={option.value}>
              {option.label}
            </Checkbox>
          )
        }
      </div>
    );
  }

感谢反馈，可以先用 Form 的 initialValue: [] 来临时修复。
