Hi,

I have a user object which has a set of roles. Roles are displayed on jsp form by way of spring controllers referenceData method are are rendered as checkboxes.

When adding a new user, I get following error on form submit:

Failed to convert property value of type [java.lang.String[]] to required type [java.util.Set] for property roles; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [java.lang.String] to required type [com.sample.domain.Role] for property roles[0]: no matching editors or conversion strategy found
