Grails find Domain and then Save it

What I want to do is find a domain and then either create a new one or save the pre-existing one. Here is the code that I am currently working with (in this project, skeleton is the package name):

    def save() {
        Class lob = grailsApplication.getDomainClass('skeleton.'+params.lob.name)
        def instance = lob.get(params.lob.id)
        if (instance){
            params.data.each { name, value ->
                if (instance.metaClass.hasProperty(name)){
                    instance[name] = value
                }
            }
        }else{
            instance = new lob()
            params.data.each { name, value ->
                if (instance.metaClass.hasProperty(name)){
                    instance[name] = value
                }
            }
        }
    }

This doesn't seem to be working. Can anyone help me with the solution?

The object returned by getDomainClass is an instance of GrailsDomainClass. To get the actual domain class on which you can call get, first call getClazz on it. For example:

Class lob = grailsApplication.getDomainClass('skeleton.'+params.lob.name).clazz

In addition, you'll have to call newInstance on the class object rather than using the new keyword to create a new instance.
