If you do the following I am pretty sure it would work, assuming you are
pasing in the id for dataManager.searchStories(id) .
Action class:
================
public class StorySearch extends ActionSupport implements Preparable {
private List<Story> stories = null;
private String id; //add getters and setters for id
...
public void prepare() throws Exception{
if(id != null ){
stories = dataManager.searchStories(id);
}
}
public String execute() throws Exception {
...
for (Story story : stories) {
System.out.println(" "+story.getId());
}
return SUCCESS;
}
public List getStories() {
return stories;
}
Struts.xml
==============
Use the following in interceptor stack in the display action
<interceptor-ref name="paramsPrepareParamsStack"/>
If that doesn't work, I'm really not sure what to tell you. That was how
I ended up getting my list to load.
The interceptor stack will load the id from the request. Then run
Prepare to get your list data before calling the jsp and execute. At
least I believe that is how it works.

Hello Scott.
..but.. the list is a property of the action, and it's populated in
the execute method.. the JSP, should be rendered after
the execute method has returned, and so at that time it
should be safe to get the stories from the action, as
by now it should be set and ready.
Do I miss anyhing?
