@fabpot anything left for this PR ?

@bamarni Can you add some unit tests and also update the FormExtensionInterface interface phpdoc as `getTypeGuesser` can now return `null`? Thanks. ping @bschussek

I've added a few tests covering this.
@fabpot : the phpdoc is already correct, it currently can return null, this only occurs with this convenient class.

This PR breaks FormFactory::createBuilderForProperty(), which expects a guesser to be present. Can you check the component for other uses of the guesser and add a null-check there?

I cannot find other places than the factory (searching for 'getTypeGuesser').

You should also adapt `FormRegistry::getTypeGuesser()` not to build a `FormTypeGuesserChain` if the array of guessers is empty. In that case it will return now `null` (adapt the doc block). We also need a different was of checking if the type guessers have already been parsed in FormRegistry. Otherwise the first if condition in `FormRegistry::getTypeGuesser()` will never become false. You could for example initialize the property `$guesser` to `false` and only set it to `null` after the first run of `getTypeGuesser()`.

good catch I had missed it! I've applied your suggestion in the latest commit. Do you see anything else before I squash?

A test for `FormRegistry::getTypeGuesser()` would of course be awesome.

Then it was already awesome! (see https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Form/Tests/FormRegistryTest.php#L252)
I've also added one for the null case if it's what you meant.
[Validator] Added delimiter escaping to Validator\Constraints\Regex::getNonDelimitedPattern
[Form][Validator] Added htmlPattern option for Regex Validation.
[Validator] Fixed Validator\Constraints\Regex::getNonDelimitedPattern variable declarations
[Validator] Fixed tests for Regex htmlPattern option (instead of html_pattern)
[Validation] tweaked generation of pattern to include .* when not anchors are present. Also removed the exception and made getNonDelimitedPattern private
This demonstrates the issue described in symfony/symfony#3354. FieldType no longer has access to the child type's data_class option, which makes it unable to create the default closure for empty_data.
