… (issei-m) This PR was merged into the 2.7 branch. Discussion ---------- [Form] ArrayChoiceList can now deal with a null in choices re-create for mistaken #17502 --- | Q | A | ------------- | --- | Bug fix? | yes | New feature? | no | BC breaks? | no | Deprecations? | no | Tests pass? | yes | Fixed tickets | - | License | MIT | Doc PR | - Documentation says, since 2.7, choice value is treated as corresponding item value (if `choices_as_values` option is true). Null as well. ```php $builder->add('attending', 'choice', array( 'choices' => array( 'yes' => true, 'no' => false, 'maybe' => null, ), 'choices_as_values' => true, )); ``` But actually null doesn't work as expected since `ArrayChoiceList::getChoicesForValues()` uses `isset` to check whether given value exists in its choices. It should use `array_key_exists` instead to do so here. Commits ------- 68292bb [Form] ArrayChoiceList can now deal with a null in choices
