For tests, I think mixed is allowed. For callbacks, there are types in BaseModel, if you've forgotten or simplified it on purpose.

And what about the other methods with arrays? afterFindMethod beforeDeleteMethod...

[samsonasik]

it use mixed item already, with string key.

This PR only change when there is an array dim fetch $param[key] in the method.
