Cannot read property 'split' of null

Versions:

• VueJs: 2.1.4
• Vee-Validate: 2.0.0-beta.17

Description:

Getting vue.runtime.common.js?d43f:423 TypeError: Cannot read property 'split' of null(…) error.

Steps To Reproduce:

Template used:

<div>
   <input
        type="text"
        name="email"
        v-model="form.email"
        v-validate data-rules="required|email"
        class="full-width"
        :class="{'has-error': errors.has('email')}"
      >
</div>

All data-* attributes have been prefixed with vv

so you should change data-rules to data-vv-rules.

It seems data-vv-rules is now deprecated. I tried to get the same result with v-validate:myProperty.initial="'required'" but it didn’t work and I got the error mentioned above in the title.
