unregister looks for non-existent field

heygambo commented 7 years ago

vue & vue-validator version

2.0.3, 3.0.0-alpha.1

Problem

There is a callback being called when I destroy a the Vue component. That leads the validator's unregister function to be called.

It always leads to an error that I cannot make any sense of so far.

It iterates two times. The first time is correct, but this._validityWatchers changes in the second run so that the watcher cannot be found.

Code

That's the template:

<template>
  <validation name="validation">
    <form novalidate @submit.prevent="submit">
      <validity field="complaint" group="dispute" :validators="{ required: true, minlength: 4 }">
        <input @input="handleValidate" id="complaint" type="text">
      </validity>
      <validity field="body" group="dispute" :validators="{ required: true, minlength: 4 }">
        <textarea @input="handleValidate" id="body"></textarea>
      </validity>
    </form>
  </validation>
</template>
