Browser caching of page content has negative security implications when your application runs on shared terminals (like the public library). You can turn it off with this simple phase listener. Well, maybe. As some of the comments indicate, browsers are finicky, and of course, we never trust the browser, anyway, so using this technique is certainly not a security guarantee of any kind. import javax.faces.context.FacesContext; import javax.faces.event.PhaseEvent; import javax.faces.event.PhaseId; import javax.faces.event.PhaseListener; import javax.servlet.http.HttpServletResponse; public class CacheControlPhaseListener implements PhaseListener {      public PhaseId getPhaseId()      {          return PhaseId.RENDER_RESPONSE;      }      public void afterPhase(PhaseEvent event)      {   ...

I you want to make a dynamic navigation Pane like this when you click on the tree node on the right side, the page fragment on the left side is populated dynamically at runtime with a navigationPane.The commandNavigationItems are rendered at runtime. To do this , follow theses steps: 1- you must have a database table that stores the data of the commandNavigationItem like this CREATE TABLE SMM_SYS_OBJECTS (   ID                NUMBER(10)                  NOT NULL,   OBJECT_REASON     VARCHAR2(3 BYTE)            DEFAULT 'REP'                 NOT NULL,   OBJ_SEQ           NUMBER(3),   FILE_TYPE         VARCHAR2(1 BYTE)            DEFAULT 'M'                   NOT ...

Hi This error happens when you make a nested a pplication module. to solve this error go to the page definition of your page or fragments and search for " Binds=" as follow   <iterator RangeSize="25" DataControl="HrmsAppModuleDataControl"               id="EmpVacationsViewIterator" Binds="Root.VacAppModule.EmpVacationsView" />   </executables> then open the property pallet  and remove the value of "binds" property then click edit and select your view object from the iterator, for example see this picture

In Jdeveloper 12 c , there is a bug  when you create a lov switcher. The Bug is the display list is disabled. You cannot add or delete any display attribute in the display list as show in this image To solve this problem , you have to edit the source of the view object by adding  this tag  <AttrArray Name="ListDisplayAttrNames"/> inside the list binding tag Example      <AttrArray Name="ListDisplayAttrNames">       <Item Value="Description"/>       <Item Value="RefNum"/>     </AttrArray> see the image below
