[Form] Document that "collection" type is buggy before 2.1

[webmozart]

The title says it all. I'm not sure whether the "collection" type is really usable in 2.0. In 2.1, it has been fixed, but requires Doctrine 2.1.?/2.2.3 due to

Hey!

Actually, if this is entirely about deleting, I think we have this covered already. It's quite a bit of work, but see the "Doctrine: Ensuring the database persistence" sidebar below this: http://symfony.com/doc/current/cookbook/form/form_collections.html#allowing-tags-to-be-removed

But, we have not yet updated this doc for the additions in 2.1. For 2.1, are the changes you're talking about the addXxx and removeXxx functionality with by_reference false? Or are there even more features to help out?

Unless there's something missing for 2.0, I think we should close this issue and open a new one for the 2.1 changes to collection.

Thanks Bernhard!

Thanks!
