There was a problem hiding this comment.
No typo. It's bound empty (without data) while the form has no (empty) data. It's slightly confusing, I agree.

I see. The other test names also confused me. I think it would be more clear with on preposition.
So testBindEmptyDataOnEmptyDataCreatesNoObjectIfNotRequired and testBindOnEmptyDataCreatesObjectIfClassAvailable.

…ata handling of collections (peterrehm) This PR was squashed before being merged into the 2.5-dev branch (closes #9773). Discussion ---------- [Form] Added delete_empty option to allow proper emptyData handling of collections | Q | A | ------------- | --- | Bug fix? | yes | New feature? | yes/no? | BC breaks? | no | Deprecations? | no | Tests pass? | yes | Fixed tickets | #9375 | License | MIT | Doc PR | symfony/symfony-docs#3338 This PR adresses the issue that if you have a form collection with the option required => false and you submit an empty collection so you will get a ArrayCollection that contains en element with the value null. This behaviour was introduced with the following changes from #3257 In addition to the above mentioned ticket there is also a description about the same issue here: http://stackoverflow.com/questions/19474872/symfony2-form-collection-allow-add-and-allow-delete-null-error-silex With the changes of this PR the new option empty_data is introduced. With this option you will be able to ignore/delete such empty collections, so they will neither be validated nor appear as empty field in the result. The option will remove/ignore such empty collections if you add them newly and if allow_add is enabled and removes such empty collections only if allow_delete is enabled. With setting required and empty_data accordingly it will be now flexible to customize to the outcome you want to achieve. Thanks to @bschussek for the great work together - We have to discuss how to name this option so if delete or ignore is the appropriate name.
