title: Vue model that doesn't exist on creation
body: <p>This is my code:</p>
  <pre><code>      &lt;lm-contact-type-select
            v-model=&quot;value.dimensions[0]&quot;
        /&gt;
  </code></pre>
  <p>and the problem is that sometimes value doesn't have dimensions, which cause an error. What can I do to prevent it?</p>
