Hello, sorry for my english, in the file Providers_model.php in de functions api_decode and api_encode is missing de field language. If you try to create a provider by API, it doesn't take the language field. The bug is in 1.5 alpha 1
FIX
include in api_decode function
if (array_key_exists('language', $provider)) {
$decoded_resource['language'] = $provider['language'];
}
include in api_encode function in $encoded_resource array
'language' => $provider['language']
Great app!! Congratulations!!
