wizard in JSF using savestate or keepalive
Hello everyone,
I want to implement wizard in my application. In that on one page i have a datatable, this datatable has one column as checkbox. I go to this page using next button and i select some checkboxes then i go back or to next page. After that if i come back to this page using prev/next button i should see all the selected and unselected checkboxes as the were.
I tried using savestate but its not working properly. Please help me to get through this.
Thanks.

You want to store values in session (save state), but you can't use session?
Please think about it twice ;) Well, here are some suggestions:
1) Split the backing beans in one request scoped bean for page actions and one session scoped bean for session data (the checkbox list for example).
2) Use FacesContext.getCurrentInstance().getExternalContext().getSessionMap() to retrieve and store the checkbox list in, instead of a bean property.
public class MyBean {
public List getCheckboxList() {
return ext.getSessionMap().get("MyBeanCheckboxList");
}
public void setCheckboxList(List checkboxList) {
ext.getSessionMap().put("MyBeanCheckboxList", checkboxList);
}
}
