[Form] allowed no type guesser to be registered
Discussion
----------
[Form] made the factory builder pass null when no type guesser registered
reopened #5422 against 2.1 as it's a bug fix

@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.
---------------------------------------------------------------------------
by bamarni at 2012-11-08T18:52:13Z
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.
