Rules are as follows:
* If multiple is true, then the empty_value is ignored
* If not, and if the field is not required, the empty_value is set to the empty string by default and displayed
* If the field is required, and if the user explicitely set the empty_value, then it is displayed
* kriswallsmith/form/collection-proto:
added script[type="text/html"] collection prototype to form themes
[Form] removed collection prototype from form tree
The current implementation is not ready for inclusion in 2.0. It has several
known problems (security, not possible to disable it, not "cloud-compatible",
...) and it's not a must have feature anyway.
Some references:
* Security issue in FileType: https://github.com/symfony/symfony/issues/1001
* Validation fails on file, still stored in TemporaryStorage: https://github.com/symfony/symfony/issues/908
* Add a size argument & ability to configure TemporaryStorage: https://github.com/symfony/symfony/pull/748
This feature should be reworked and discussed for inclusion in 2.1.
