Hi all,

           I am using my custom model with trinidad table as shown below. I want to instantiate my custom model only once regardless of backing bean. Is it possible?

Model Class:
          
public MyModel extends CollectionModel {

    // logic
}


Backing Bean:

public MyBackingBean {

        private MyModel  model;

         public MyBackingBean() {
             model = new Model(/*some collection */);
         }

          public MyModel  getModel() {
                return model;
           }
           
}

JSP page:

<tr:table value="#{myBean.model}" .....>


The backing bean is in request scope.


Problem:

Since the backing bean is in request scope, for every request new instance of model is created. I don't want to create new instance of my custom model since i am storing some state in it. Is there any way to create only one instance of  custom model regardless of backing bean scope, like trinidad creates only one instance of SortableModel.
