Hi,
I got start, but ran into a problem. In the code below the line
Object actionBean = context.getActionBean();
always gives DefaultViewActionBean - not my action bean. Can someone help?
Thanks

@Intercepts({LifecycleStage.ActionBeanResolution, LifecycleStage.EventHandling})
public class PageScopeInterceptor implements Interceptor
{
private static final String PAGE_SCOPE_KEY = "_pageScope";
public Resolution intercept(ExecutionContext context) throws Exception
{
Resolution resolution = context.proceed();
// Restores values from session.
if
(LifecycleStage.ActionBeanResolution.equals(context.getLifecycleStage())) {
bindPageScopeFields(context);
}
if
(LifecycleStage.EventHandling.equals(context.getLifecycleStage())) {
serializePageScopeFields(context);
}
return resolution;
}
private void serializePageScopeFields(ExecutionContext context)
throws IllegalArgumentException,
IllegalAccessException, IOException
{
HashMap<String, Object> map = new HashMap<String, Object>(5);
Object actionBean = context.getActionBean();
for (Field field : actionBean.getClass().getDeclaredFields()) {
// check if field has annotation
if (field.getAnnotation(PageScope.class) != null) {
field.setAccessible(true);
map.put(field.getName(), field.get(actionBean));
}
}
String _pageScope = toString(map);
context.getActionBeanContext().getRequest().setAttribute(PAGE_SCOPE_KEY,
_pageScope);
}
private void bindPageScopeFields(ExecutionContext context)
throws IllegalArgumentException,
IllegalAccessException, IOException,
ClassNotFoundException
{
String pageScope =
context.getActionBeanContext().getRequest().getParameter(PAGE_SCOPE_KEY);
if (pageScope == null)
return;
@SuppressWarnings("unchecked")
HashMap<String, Object> map = (HashMap<String, Object>)
fromString(pageScope);
Object actionBean = context.getActionBean();
for (Field field : actionBean.getClass().getDeclaredFields()) {
// check if field has annotation
if (field.getAnnotation(PageScope.class) != null) {
if (map.get(field.getName()) != null) {
field.setAccessible(true);
field.set(actionBean,
map.get(field.getName()));
}
}
}
}
