The mapping of property paths to arrays has changed.

• The mapping of property paths to arrays has changed.

  Previously, a property path "street" mapped to both a field $street of a class (or its accessors getStreet() and setStreet()) and an index ['street'] of an array or an object implementing \ArrayAccess.

  Now, the property path "street" only maps to a class field (or accessors), while the property path "[street]" only maps to indices.

  If you defined property paths manually in the "property_path" option, you should revise them and adjust them if necessary.

  Before:

  $builder->add('name', 'text', array(
    'property_path' => 'address.street',
  ));

  After (if the address object is an array):

  $builder->add('name', 'text', array(
    'property_path' => 'address[street]',
  ));

  If address is an object in this case, the code given in "Before" works without changes.
