Is it really just on 2.8, or does 2.7 have the same issue? |

It seems to be the most convenient way to do it, but don't we lose the property path information for this violation ? And by doing so we can't customize the error message easily (as it won't be bound to a constraint anymore). |

I'm closing because the PR is old and another approach is needed per the discussion. Feel free to resubmit of course. Thanks for the proposal. |

This PR aims to solve a problem (might be considered a bug) we encountered when validating some API input.
As stated in the related issue, when validating a value that is not an array-like type against a composite constraint (either All or Collection), we get an exception.
This obviously does not cause much harm when used with the Form component where you control the data structure but is quite an issue when you must validate freely formatted content.
One of the obvious solution would have been to add a Type Constraint together with the Composite constraint but the constraints not being lazy executed, the exception is thrown anyway.
