* The "data_class" option now *must* be set if a form maps to an object. If
|
||||
you leave it empty, the form will expect an array or a scalar value and
|
||||
fail with a corresponding exception.
|
||||
|
||||
Likewise, if a form maps to an array, the option *must* be left empty now.
|
||||
|
||||
* 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.
