This worked in beta1 but not in beta2 [seems to be a theme today :
( ] This was Berhard's nifty solution to my AJAX city/state
problem.
I print_r()'d the array ($realtor_search_params) and it is indeed
populated with data (an associative array), but I get the following
exception when I run it:
"Warning: array_key_exists() expects parameter 2 to be array, null
given ..."
Did something change in the event (or form) system?
>From Controller:
$realtor_search_form = $this->get('form.factory')->create(new
RealtorSearchType(), $realtor_search_params);
>From RealtorSearchType:
$builder->addEventListener(Events::preSetData, function
(DataEvent $event) use ($refreshCity) {
$data = $event->getData();
if(array_key_exists('state', $data)) // ERROR IS HERE,
$data is null
$refreshCity($event->getForm(), $data['state']);
});
