Question

I have these entities: - Store and Package
I'd like to build a StoreType form where i add package Id.
I've made a StoreType Form class: (I would expect to get a select box from this, where all package are listed)
I've add the package through one to one, but my problem is when i add package in store form then form is create but in my database store table column package are empty.i don't know why?

I think you forget to do this in your createAction :
$request = $this->getRequest();
$form->setData($request->getPost());
