Re: Save objects in the session

hi,

You can create your own statefull page by

public class StatefulPage implements Stateful

use this page wherever required.

Hi,
I have a page similar to the Search Table Pattern example 
(http://click.avoka.com/click-examples/table/search-table.htm).
However, my search is more complex than in the example since you can add and 
remove filters to narrow-down your search.
To make this work I must save an object that contains the active filters for 
the search.

With statefull pages this worked automagically, since my object was a field of 
the class and so was saved automatically.
In click 2.3 stateful pages are deprecated, so what is the best way to achieve 
the same result?

As of now i have solved this issue by creating a fake control to hold my 
object, that is persisted as other stateful controls:

public class FakeControl<T extends Serializable>  implements Stateful {
     private String name;
     private T object;

     public FakeControl(String name) {
         this.name = name;
     }
     @Override
     public Object getState() {
         return object;
     }
     @SuppressWarnings("unchecked")
     @Override
     public void setState(Object state) {
         this.object = (T) state;
     }
     public T getObject() {
         return object;
     }
     public void setObject(T object) {
         this.object = object;
     }
     public void removeState(Context context) {
         ClickUtils.removeState(this, getName(), context);
     }
     public void restoreState(Context context) {
         ClickUtils.restoreState(this, getName(), context);
     }
     public void saveState(Context context) {
         ClickUtils.saveState(this, getName(), context);
     }
     public String getName() {
         return name;
     }
}
