Jira issue originally created by user cloun:
I have a custom type EnumDatatype. If I set single parameter for repository's method findBy everything works fine: value converted to database format (method convertToDatabaseValue invoked). But if I specify array of values of such type it will not convert to database format.

Did you implemented canRequireSQLConversion ?
Could you try to add a failing test case ?
Comment created by @beberlei:
This can't be fixed because of architectural reasons. Only strings and integers can be arrays
