Answer 1

After lots of research and tries i found the solution of it. For Grails domain we can fix this problem by adding the sqlType as "float" for validation mode.

In Result.groovy

class Result{
    Double discount

    static mapping = {
        discount column: "discount", sqlType: "float"
    }

    static constraints = {
        discount(nullable: true)
    }
}

So it will remove the error in validation mode.
