Most Used codes

1. FOR FACES MESSAGE POPUP -To show warning/error/info messages on view page

 

1. FacesContext fctx = FacesContext.getCurrentInstance();
2. FacesMessage msg=new FacesMessage(Severity,String Summary, String Message);
3. fctx.addMessage(inputText.getId(), msg);

For Eg:

1. FacesContext fc=FacesContext.getCurrentInstance();
2. FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_WARN, "Save It" ,"Before Navigating to details Click Save..");
3. fc.addMessage(null,msg);

2.TO GET OPERATION BINDING:

2. BindingContext.getCurrent().getCurrentBindingsEntry().getOperationBinding
3. ("CreateInsert2").execute();
     OR
6. BindingContainer bindings = getBindings();
7. OperationBinding glOP = bindings.getOperationBinding("Commit");
8. glOP.execute();
10. if (!glOP.getErrors().isEmpty()) { //in case operation binding returns error
11. } else{
12. }

3.TO GET CURRENT ROW FROM ITERATOR BINDING:

2. BindingContext btx = BindingContext.getCurrent();
3. DCBindingContainer dcbct = (DCBindingContainer)btx.getCurrentBindingsEntry();
5. DCIteratorBinding binding = dcbct.findIteratorBinding("EmployeeIterator");
6. Row currentRow = binding.getCurrentRow();
     OR
9. DCIteratorBinding iterBind= (DCIteratorBinding)dcbct .get("testIterator");
10. String attribute = (String)iterBind.getCurrentRow().getAttribute("empName");
     OR
14. FacesContext ctx = FacesContext.getCurrentInstance();
15. ExpressionFactory exf = ctx.getApplication().getExpressionFactory();
16. ValueExpression vale = exf.createValueExpression(ctx.getELContext(), "#{bindings.EmployeeIterator.currentRow.dataProvider}", Emp.class);
17. Emp name= (Emp)vale.getValue(ctx.getELContext());

4.TO REFRESH THE PAGE:

1. protected void refreshPage() {
2. FacesContext fctx = FacesContext.getCurrentInstance();
3. String refreshpage = fctx.getViewRoot().getViewId();
4. ViewHandler ViewH = fctx.getApplication().getViewHandler();
5. UIViewRoot UIV = ViewH.createView(fctxc, refreshpage);
6. UIV.setViewId(refreshpage);
7. fctx.setViewRoot(UIV);
8. }

5.TO REFRESH (PPR) ANY UI COMPONENT:

1. AdfFacesContext.getCurrentInstance().addPartialTarget(UIComponent);

6.TO OPEN A POPUP

1. private void showPopup(RichPopup pop, boolean visible) {
2. try {
3. FacesContext context = FacesContext.getCurrentInstance();
4. if (context != null && pop != null) {
5. String popupId = pop.getClientId(context);
6. if (popupId != null) {
7. StringBuilder script = new StringBuilder();
8. script.append("var popup = AdfPage.PAGE.findComponent('").append(popupId).append("'); ");
9. if (visible) {
10. script.append("if (!popup.isPopupVisible()) { ").append("popup.show();}");
11. } else {
12. script.append("if (popup.isPopupVisible()) { ").append("popup.hide();}");
13. }
14. ExtendedRenderKitService erks =
15. Service.getService(context.getRenderKit(), ExtendedRenderKitService.class);
16. erks.addScript(context, script.toString());
17. }
18. }
19. } catch (Exception e) {
20. throw new RuntimeException(e);
21. }
22. }
