State And Properties

BaseForm tracks the original state and the current state of each field.

form.isDirty() // any field modified
form.isDirty('email') // specific field modified

form.touch('email')
form.isTouched('email')

Properties

properties.<field> exposes:

• model (a ComputedRef compatible with v-model)
• errors (array)
• dirty and touched

Example:

<input v-model="form.properties.email.model.value" />
<div v-if="form.properties.email.dirty">This field has been changed</div>
<div v-if="form.properties.email.errors.length">{{ form.properties.email.errors[0] }}</div>

Nested Object Properties

If a field is declared as PropertyAwareObject, its nested keys are also exposed as property-aware fields.

<template>
  <input v-model="form.properties.payload.command.model.value" />
  <div v-if="form.properties.payload.command.dirty">Command changed</div>
  <div v-if="form.properties.payload.command.errors.length">
    {{ form.properties.payload.command.errors[0] }}
  </div>
</template>

This is opt-in. Plain objects do not expose nested property-aware keys.
