Pass current component to validation rule?

[achingbrain]

I have a form with a variable number of pairs of input fields. If one item in a pair has a value, the other needs to have a value too.

The form looks something like this:

<Form>
  <Input type='text' name='input1' data-paired-with='input2' validations={['paired']} />
  <Input type='text' name='input2' data-paired-with='input1' validations={['paired']} />
  <Input type='text' name='input3' data-paired-with='input4' validations={['paired']} />
  <Input type='text' name='input4' data-paired-with='input3' validations={['paired']} />
  <!-- other stuff here -->
</Form>

The code that invokes a rule only passes the value and the set of components in, so you don't know what the current component being validated is, only it's value:

if (!rules[validations[i]].rule(component.state.value, this.components)) {

If it passed the current component in too:

if (!rules[validations[i]].rule(component.state.value, this.components, component)) {

I could perform this sort of validation:

{
  paired: {
    rule: (value, components, component) => {
      // find paired component
      const other = components[component.props['data-paired-with']]

      if (!value && other.state.value) {
        return false
      }

      return true
    },
    hint: value => {
      // return error message
    }
  }
}

Is there any chance of passing the current component to the validation rule?

Hi! When I look at const password = (value, props, components) from the example in the readme, it seems to me that props now serves this purpose. Is that correct (and this ticket is done) or am I misunderstanding the function of props? Thanks!
