@mrcmorales can you add documentation for this please

[mrcmorales]

@phiamo I can, but this feature is from symfony, then this doc would be in symfony doc.

This doc are done in symfony doc but not merge yet.

Will we need an and label_format is defined? as well for previous versions of Symfony since this variable won't be defined?

[phiamo]

Not sure if the is empty does the trick, but yes thats what i mesnt too. Can smbd confirm this?

[mrcmorales]

@phiamo to be secure, I can add label_format is defined condition.

[mrcmorales]

@phiamo I tested with sf 2.3 and is necessary control if var is defined, I updated PR.
