form.render returning an empty hash

[Bodacious]

I'm seeing strange behaviour in my app.

When I call form.render I get an empty hash {}.

The exact same code loaded in another app works fine - so I'm starting to think it might be a clash with something else in my environment. Are there any known issues?

Here's my Gemfile:

source 'https://rubygems.org'

gem "motion-pixatefreestyle"
gem 'motion-yaml'
gem 'motion-testflight'
gem "motion-cocoapods"
gem "motion-persistable"
gem "bubble-wrap", require: false
gem 'formotion'
gem "motion-i18n"
gem "i18n_tools", :require => "i18n_tools/tasks"
gem 'rake', require: false
gem 'sass', '3.3.7', require: false
gem 'guard-sass', require: false
gem 'rb-fsevent', '~> 0.9', require: false
gem "cocoapods", require: false

group :spec do
  gem 'guard', require: false
  gem 'guard-motion', require: false

  gem 'motion-redgreen'
  gem 'motion-stump'
end

And my Rakefle

# -*- coding: utf-8 -*-
$:.unshift("/Library/RubyMotion/lib")
require 'motion/project/template/ios'
require 'motion-cocoapods'
require File.join(File.dirname(__FILE__), 'version')


begin
  require 'bundler'
  if ARGV.join(' ') =~ /spec/
    Bundler.require :default, :spec
  else
    Bundler.require
  end
rescue LoadError
end

require 'bubble-wrap/core'
require 'bubble-wrap/mail'

Motion::Project::App.setup do |app|
  # Use `rake config' to see complete project settings.
  app.name       = 'MyApp'

  app.device_family = [:ipad]
  app.interface_orientations = [
    :portrait_upside_down, :portrait, :landscape_left, :landscape_right]


  app.frameworks += %w[ Accelerate AudioToolbox Social MessageUI]
  app.weak_frameworks += %w[ AdSupport ]

  app.pixatefreestyle.framework = 'vendor/Pods/PixateFreestyle/PixateFreestyle.framework'

  app.sdk_version          = '7.1'
  app.deployment_target    = '7.0'

  app.fonts = font_paths

  app.pods do
    pod 'Mixpanel', "~> 2.4.0"
    pod 'PixateFreestyle', '~> 2.1.3'
    pod 'TestFlightSDK', '~> 3.0.2'
    pod "ChimpKit"
  end

  if ARGV.join(' ') =~ /spec/
    app.redgreen_style = :full # default: :focused
  end

  app.testflight do
     app.testflight.app_token        = # ...
     app.testflight.api_token        = # ...
     app.testflight.team_token       = # ...
     app.testflight.notify           = true # default is false
     app.testflight.identify_testers = true # default is false
   end

end

Hm no clue - you can copy the render code in your project and add some logging to see where it's going wrong?

[kylebragger]

I can't tell if this is a bug, but if you don't explicitly set a row's key when building the form, then regardless of its value, it's stripped from the final kv array because the key is nil.

So, simply setting row.key in the builder fixes the issue. [I had the same issue. :)]

[Bodacious]

I have no idea what's wrong here - the problem goes away if I copy/paste row.rb into my own application.

I didn't change it in any way, I only copied it over.

Very weird.
