AutoForm with Meteor – Check validity of entire form? - meteor

Question

I'm trying to make some helpers in the template where my AutoForm form lives to change some elements out side of the form to reflect errors. I've tried using
Template.signUp.helpers
isValid: ->
AutoForm.getValidationContext('signUp').isValid()
But that just returns the following error:
Exception in template helper: TypeError: Cannot read property '_resolvedSchema' of undefined
Here's the template:
<template name="signUp">
{{#if isValid}} do something {{/if}}
{{#autoForm id="signUp" schema="Schemas.SignUp" type="normal"}}
<div class="input {{#if afFieldIsInvalid name='firstName'}}error{{/if}}">
<label for="firstName">{{data.firstName}}</label>
{{> afFieldInput name="firstName" type="text"}}
</div>
<div class="input {{#if afFieldIsInvalid name='lastName'}}error{{/if}}">
<label for="lastName">{{data.lastName}}</label>
{{> afFieldInput name="lastName" type="text"}}
</div>
<div class="input {{#if afFieldIsInvalid name='email'}}error{{/if}}">
<label for="email">{{data.email}}</label>
{{> afFieldInput name="email" type="email"}}
</div>
<div class="input">
{{> afFieldInput name="optIn" type="boolean-checkbox"}}
</div>
<button type="submit" class="btn full" data-analytics='{"eventCategory":"Sign Up","eventAction":"Click","eventLabel":"{{data.submit}}"}'><span>{{data.submit}}</span></button>
{{/autoForm}}
</div>
</div>
Any help is greatly appreciated, thanks!
****UPDATE – Found Solution****
So after lots of playing I discovered that when you're trying to validate an AutoForm outside of the AutoForm context, you should use SimpleSchema to validate.
Here's where I'm defining the schema and saving the named context (coffeescript)
#Schemas = {}
#Schemas.SignUp = new SimpleSchema
firstName:
type: String
optional: false
lastName:
type: String
optional: false
email:
type: String
regEx: SimpleSchema.RegEx.Email
optional: false
optIn:
type: Boolean
label: Localization.signUp.optIn
optional: true
defaultValue: false
#SignUpForm = Schemas.SignUp.namedContext('signUp')
And here is where I'm using SimpleSchema to validate the entire form.
Template.signUp.helpers
isValid: ->
SignUpForm.isValid()
