In our application, we call these "loop" pages. Here's how we implemented it:
public abstract class LoopLink extends SubmitLink
{
public LoopLink(String id)
{
super(id);
setDefaultFormProcessing(false);
}
protected abstract Page getLoopPage();
@Override
public final void onSubmit()
{
setResponsePage(getLoopPage());
setRedirect(true);
}
}
public class LoopPage extends WebPage
{
protected final Breadcrumb breadcrumb;
public LoopPage()
{
this.breadcrumb = new Breadcrumb();
}
protected void redirectToDestination()
{
breadcrumb.redirectToDestination();
}
protected Page getDestinationPage()
{
return breadcrumb.getDestinationPage();
}
}
public class Breadcrumb implements Serializable
{
private final PageReference destination;
public Breadcrumb()
{
this.destination = PageReference.forRequestedPage();
}
public Link createCancelLink(String id)
{
return new CancelLink(id);
}
private class CancelLink extends Link
{
private static final long serialVersionUID = 1L;
public CancelLink(String id)
{
super(id);
}
public void onClick()
{
redirectToDestination();
}
}
public void redirectToDestination()
{
RequestCycle.get().setResponsePage(destination.getPage());
RequestCycle.get().setRedirect(true);
}
public Page getDestinationPage()
{
return destination.getPage();
}
}
So, to initiate going through the "loop", you just set up a LoopLink.
The LoopPage subclass will do something to select some information and
then go back to the page from whence the loop began:
protected void onCreate(Foo foo)
{
fooRepostiory.add(foo);
final Page page = getDestinationPage();
if (page instanceof FooSelectionListener)
{
((FooSelectionListener) page).fooSelected(foo);
}
info("New foo created successfully!");
redirectToDestination();
}
This seems to work for us just fine.
