I have a filter which maps just before the Faces Servlet and populate some Attributes in the HttpSession before it proceeds with the request
if (_clientUser != null && !_clientUser.isEmpty()) {
session.setAttribute(CLIENT_USER_URI_PARAM_NAME, _clientUser);
filterChain.doFilter(servletRequest, servletResponse);
return;
}
Within the URI there are some informations for which Task-flow should be addressed
faces/adf.task-flow?adf.tfId=task-flow-definition-id&adf.tfDoc=/WEB-INF/task-flow-definition-id.xml
After I proceed the request there is a method-call within the bounded task flow which is called before the view (lets call the view MainPage), by making it default activity
<default-activity>doStuff</default-activity>
The Method itself is within a PageFlowScoped Managed Bean, which is added to the task-flow-definition-id.xml
Here is the doStuff Method which is called before the "MainPage"-View
public class Controller{
public void doStuff {
FacesContext ctx = FacesContext.getCurrentInstance();
Map sessionMap = ctx.getExternalContext().getSessionMap();
String clientUser = (String) sessionMap.get(CLIENT_USER_URI_PARAM_NAME);
AppModImpl am = getApplicationModule();
DBTransaction transaction = am.getDBTransaction();
//do more stuff
}
}
public AppModImpl getApplicationModule() {
FacesContext fc = FacesContext.getCurrentInstance();
Application app = fc.getApplication();
ExpressionFactory elFactory = app.getExpressionFactory();
ELContext elContext = fc.getELContext();
ValueExpression valueExp =
elFactory.createValueExpression(elContext, "#{data.AppModDataControl.dataProvider}", Object.class);
AppModImpl am = (AppModImpl) valueExp.getValue(elContext);
return am;
}
Everything works fine till here. But if I try to get the Application Module. There is non. This application normally doesn't have any DataControl, because is just a root Application which holds different components which have been added by ADFLibrarys, but I added an DataControl to the DataBindings.cpx and a iterator to the MainPagePageDef (just to include a DataControl in the bindings) but still no result.
Do you have any advice for me how I can access the Application Module? FacesServlet should have been already created the necessary FacesContext by the time the Managed Bean is called or does it only create a new FacesContext the Time an actual Page (jspx/jsf) loads?
