How to adjust constraints / DB mapping for Map within grails domain class

Question

Following grails domain class:

class MyClass {
  Map myMap
}

Now for myMap, grails automatically creates a new table for the elements in th

Answer 1

An alternative approach I used successfully was to push the map out into a collection of a collaborator domain class.

class DynaProperty {
    String name
    String value

    static belongsTo = MyClass
    static constraints = {
        value(maxSize:4000)  //Or whatever number is appropriate
    }
}

And then in MyClass:

class MyClass {
    static hasMany = [dynaProperties:DynaProperty]
}

This is almost a map, and it gives you the ability to use dynamic finders to pull up an individual entry.
