FormItem中当定义自定义directive时报错

[wd2010]

• I have searched the issues of this repository and believe that this is not a duplicate.

Version

1.3.10

Environment

macOS10.14 chrome75 Vue2.6.10

Reproduction link

Steps to reproduce

// 自定义组件  HelloWorld.vue
<a-form :form="form">
<a-form-item>
<a-input v-decorator="['inputValue']"/>
</a-form-item>
</a-form>

// 父组件 自定义directive
<template>
<a-form :form="form">
<a-form-item>
<hello-world v-clearData></hello-world>
</a-form-item>
</a-form>
</template>

// FormItem.js
function decoratorOption(vnode) {
if (vnode.data && vnode.data.directives) {
var directive = find(vnode.data.directives, ['name', 'decorator']);  // 取到的directive为undefined，因为此时的directives是包含 自定义组件v-clearData的

warning(!directive || directive && Array.isArray(directive.value), 'Invalid directive: type check failed for directive "decorator". Expected Array, got '   _typeof(directive.value)   '. At '   vnode.tag   '.'); // 导致directive.value报错

return directive ? directive.value : null;
} else {
return null;
}
}

What is expected?

warning(!directive || directive && Array.isArray(directive.value), 'Invalid directive: type check failed for directive "decorator". Expected Array, got '   _typeof(directive.value)   '. At '   vnode.tag   '.');

期望当directive为undefined时，_typeof(directive.value) 做兼容

What is actually happening?

TypeError: Cannot read property 'value' of undefined at VueComponent.decoratorOption

在全局定义了自定义directive时
