failed to lazily initialize a collection of role In Grails

I got struck here. There is a parent Table like below.

     class Parent{
        static hasMany = [child: Child];
        static Parent findByParent(Parent parent){
        def c = Parent.createCriteria()
        def result = c.get {
        child{
             idEq(parent.id)
        }
       }
      }
     }

    class Child {

    }

Below is controller action.

    def save(Child child){
      def orderList;
      if(parent){
        orderList = parent?.child(); // here i am getting exception. failed to lazily initialize 
                                      //  a collection of role: Parent.child, no session or session  
                                        //was closed. Stacktrace follows:
      }
    }

So how to handle this situation.Or is there any Annotations to Eager initialization.

For eager fetching you can explicitly set lazy as false in your Parent domain .Try something like this 

static mapping = {
    child lazy: false
}

Hope it helps...
