merged branch bschussek/issue3288 (PR #3290)
Commits ------- 22c8f80 [Form] Fixed issues mentioned in the PR comments 3b1b570 [Form] Fixed: The "date", "time" and "datetime" types can be initialized with \DateTime objects 88ef52d [Form] Improved FormType::getDefaultOptions() to see default options defined in parent types b9facfc [Form] Removed undefined variables in exception constructor Discussion ---------- [Form] Fixed: "date", "time" and "datetime" fields can be initialized with \DateTime objects Bug fix: yes Feature addi 8000 tion: yes Backwards compatibility break: **yes** Symfony2 tests pass: yes Fixes the following tickets: #3288 Todo: - ![Travis Build Status](https://secure.travis-ci.org/bschussek/symfony.png?branch=issue3288) Fixed exception that was thrown when doing: $builder->add('createdAt', 'date', array('data' => new \DateTime())); On a side note, the options passed to `FieldType::getDefaultOptions` now always also contain the default options of any parent types. This is necessary if you want to be independent of how `getDefaultOptions` is implemented in the parent type and still rely on the already defined values. As a result, `FieldType::getParent` doesn't see default options anymore. This shouldn't be a big problem, because this method only relies on options in few cases. If it does, options now need to be checked for existence with `isset` before being used (BC break). --------------------------------------------------------------------------- by bschussek at 2012-02-09T16:14:46Z @fabpot Ready to merge. --------------------------------------------------------------------------- by bschussek at 2012-02-10T12:15:04Z @fabpot Ready to merge
