Page Refresh in JSF

When I clicked Refreshed button or pressed F5 Button.Page Refresh is not happening in xhtml.Instead it call the same action method.
can u provide me the solution for page refresh in xhtml
Edited by: 814412 on 22-Nov-2010 05:41

Hitting on F5 actually means repeating last submission.
So when you clicked on query button, and then F5, the F5 will result in as if you click on the query button again.
If you would like to be able to manually refresh a data grid for example, i think you should provide a refresh button, or a query button.

Page Refresh Issue in JSF

Hi All,
Kindly treat this on high priority.
Here's the "setup" :-
Page Refresh in JSF Application
When a user hits refresh, the behavior is different depending on if the current page was loaded via GET(outputLink) or POST(commandLink/commandButton).
If a GET, the browser simply re-asks for the page re-using the current URL.
But If a POST, the user is asked, usually, if they want to re-submit their data to the server.
The resubmitting of data happens for the last request generated by the POST method (correct me if i am wrong here)
How can one avoid doing this?
Heres "the performance" :-
I googled out, only to come across words like "jsf redirect tag"
I tried putting it in my navigational rule, only to get the error "Page could not be found. Internal Server Error 500"
Could i get my hands on "the prestige" ?
Thanks & Regards,
Darshan Shroff

Thanks for the reply.
I could not understand the logs.
Can you make any sense of this ?

Animated gif and page refresh problem

Animated gif and page refresh problem
Hi There,
I'm trying to build a simple "Please wait......" screen using jsp and javascript.
So far all is going well except that my animatate gif keeps refreshing everything the page is refresh.
Is there a way the i can prevent the body of the page from refreshing?
below is my sample code:

<jsp:useBean id="StatusBean" class="com1.CandidateRelease" scope="session"/>

Partial page refresh in REQUEST scope

Hi,
I was going through the various example of partialTrigger.
But in I am unable to find the example in where we can use the partialTrigger with having our backing bean into request scope. means Can we do partial page refresh without keeping our backing bean into session scope?
Can we do partial page refresh across different fragments (different jsf fragment - jsff ) with having the our backing bean in a request scope?
Is there any way that we can achieve this?
Please can any one provide some input or help on this?
Thank you in advance.

Hi,
Can we do partial page refresh without keeping our backing bean into session scope?
Yes, don't know how you get to this idea that you couldn't. You can use ADFFacesContext.getCurrentInstance().addPartialTarget(component)
Can we do partial page refresh across different fragments (different jsf fragment - jsff ) with having the our backing bean in a request scope?
You are posting a JDeveloper 11 question without saying it first. Also note that there is a JDeveloper 11 forum here on OTN. To answer the question, I don't think that you can do this and that instead you would use a region and contextual events to refresh the area

Store data in R/3 without page refresh

Dear BSP-Masterminds,
we need to store data in R/3 without a recurrent page refresh. The problem is that our engineers are using PDA's and the page refresh is taking too much time. The engineers are changing equipment data on the PDA's. Every time they click on save button, the data get send to the R/3 system and the checking, if the data are correct, takes up to 30 sec. Additional the new page refresh on PDA takes another 20 sec. It would be great to find a solution which stores the data somewhere and by hitting the 'final save-button' the data get checked and saved.
The worst case scenario would be a table of around 600 equipment data, so it might be a huge table that has to be stored somewhere. I thought of a client side cookie but I have no experience if it is possible to store such a big internal table and by the way I don't know if this would be possible on a PDA.
Every little hint is welcome!
Regards
Nicola

Hi,
Javascript as such can't do it without refreshing the page. You need to use the AJAX function. But you don't need to be scared about it. Just look at the web logs I've mentioned and you'll understand it quickly.
Here's an additional AJAX tutorial

How do I pass input values from a html page to a jsf page

hi,
In my project,for front view we have used html pages.how can I get input values from that html page into my jsf page.for back end purpose we have used EJB3.0
how can I write jsf managed bean for accessing these entities.we have used session facade design pattern and the IDE is netbeans5.5.
pls,help me,very urgent
thanx in advance

Simplest way is to rewrite html page into jsf page.
You can use session bean in your managed bean like this:
import javax.naming.Context;
import javax.naming.InitialContext;
public class ManagedBean {
private Context ctx;
private Object res;
// session bean interface
private Service service;
          public ManagedBean() {
            try{
                 ctx = new InitialContext();
                 res = ctx.lookup("Service");
                 service = (Service) res;
           catch(Exeption e){

Hi All,
I fixed this issue.
I used Skillbuilders modal popup plugin, to open the form page as popup when i edit the record.To implement this plugin i have already created dynamic action for edit ,create and autoclose the popup.
In the dynamic action i changed the EVENT SCOPE from BINT To LIVE and tested the application.Now its working fine.
I can able to edit the record after i hit the next/previous pagination link .
Thanks ,

Is it possible to intitate total page refresh from plugin code

In 11.1.1.4 EMAIGC we are facing following issue: Target status is not getting refreshed after dependent components status change (Which will be done through through EM Plugin UI actions). This will status will be reflected only after manual refresh.
From our plugin code , after the dependent component start/stop operations we wanted to call total page refresh, is there any way to handle this?
Thanks ,
Ramadevi

(Classic) Report losing pagination on partial page refresh - APEX feature request

I have a page with both an Interactive Report and some classic Report regions.
Based on user updates, there are many occasions where I need to do a partial page refresh.
Thanks to plugin http://www.apex-plugin.com/oracle-apex-plugins/dynamic-action-plugin/refresh-interactive-report-1.0_361.html
I'm able to refresh my IR, but not my classic report (unless I do a submit of the whole page) without losing pagination.
Request: Will a Dynamic action 'Refresh without losing pagination' be part of future apex versions?
Now, in apex 4.2, is there another work around available for classic reports?
(I use 'submit page' now as action, but it's at least a second slower as a partial refresh, and because I need it on every user update, this second becomes a big addition to user frustration).
Thanks, JP

Update report dynamically? (without page refresh)

I have a page with several regions, and only one region is visible at a time. Each region contains a report as well as a drop-down to alter the data displayed in the report. Currently each time a drop-down value is changed it submits the page, which causes the "main region" to become visible since it is set by default to display first.
Is there a basic tutorial I can follow on how to dynamically update the report output without a page refresh?
Thanks,
Steve

Is there a basic tutorial I can follow on how to dynamically update the report output without a page refresh?The easiest way to do this is using dynamic actions. Create a Refresh dynamic action for each region that executes when the associated select list is changed:
h4. When
Event: Change
Selection Type: Item(s)
Item(s): <select list associated with region>
h4. True Action
Action: Refresh
Fire On Page Load: Yes or No depending on the requirements of your application
Region: <region to be refreshed>
Ensure that the value of the associated select list is submitted into session state before the refresh by specifying it in Page Items to Submit in the Source section of the report region definition.
There are some dynamic action tutorials on the Oracle Learning Library. Doesn't specifically mention Refresh in the abstract, so it may not cover this specifically, but it is an introduction to dynamic actions in general.
(It's probably possible to create a single dynamic action to handle refreshing all of the regions: we'd need more comprehensive details of your application, preferably reproducing it or a simplified version on apex.oracle.com.)

How to retain value in LoV item in Tabular Form, after Page Refresh

Hi,
I have a tabular form, which contains 2 items(columns), of type "Select List - named LoV".
Now, 2nd item(column) in tabular form, that LoV should get populated based on user's selection value in first item LoV.
1. So how do I refer to the value, that user selected in first item's LoV? I will have to use this value as reference in LoV query of my 2nd item ( on this tabular form)
2. Everytime I select value in first item LoV, page gets refreshed, as my requirement is to calculate 2nd item's LoV based on selected value in first item. So after this page refresh, first item LoV loses its value that was selected before the page refresh happened. So how do i retain this value in first item LoV? I have an unconditional process, that on every submit(refresh) of page, I set all my items with their corresponding values. But problem is what do i mention there to refer to this first item ( of type LoV) of tabular form?
I looked in view source of my page, this item is referred as f03.
So i used "apex_application.g_f03", to set this item to its value, in my uncoditional submit process. But it did not work. I tried to refer this item as "f03" in this unconditional submit process. But still it did not help, the selected item loses its value after page refresh(submit).
Please help.
Thanks and Regards,
Ravi.

Hi Rave,
You will have to use Javascript and Ajax to change the values as ApEx submissions will lose your results unless they are saved into the database.
Remember, that as you are using a tabular form there will be lots of items called f01, fo2, fo3 etc on the page (one per row).

Why does a box that says "uninstal set" keep popping up when i go to a new page, refresh the page, or ever open up the browser ever i upgraded to the new firefox?

I upgraded to the newer version of firefox, and ever since then every time i go to a new page, refresh the page, or open it the interned a box pops up and says "uninstal set" and won't let me continue until i click "ok" why is this happening, and how can i fix it?

go to Tools, add-ons, then only disable java 6.0.22 ONLY, then you have to click on restart. That solved my problem.

Event handler when using partial page refresh ?

Hi
I have a calendar, which uses partial page refresh. The problem is how to make javascript wait until the calendar has loaded and then do some updates on the calendar (after the user has pressed the next button that runs apex.widget.calendar.ajax_calendar('S','next');, for example ). I thought I could add "onreadystatechange" (or onload) event handler to the calendar like this: onreadystatechange="checkState()", where the function would check the state and if ready then do the updates. This doesn't work. Could somebody please tell me why not ?
Tiina

Hi,
It seems that ajax calendar missing event apexafterrefresh.
I do not know is this "bug" or just feature.
That event would be useful to your case , if I understand correct what you looking for.
For workaround , you can over write original function by placing this to calendar region footer
<script>
apex.widget.calendar.ajax_calendar=function(p_calendar_type, p_calendar_action, p_calendar_date, p_calendar_end_date){
var l_cal_type_field = $v('p_cal_type_field_id');
var l_cal_date_field = $v('p_cal_date_field_id');
var l_cal_end_date_field = $v('p_cal_end_date_field_id');
var l_cal_id = $v('p_calendar_id');
var l_calendar_region = 'calendar' + l_cal_id;
if ( p_calendar_type != 'C' ){
$s(l_cal_date_field,$v('p_calendar_date'));
}else{
if ( $v(l_cal_date_field) == '' ) {
   $s(l_cal_date_field,$v('p_calendar_date'));
if ( $v(l_cal_end_date_field) == '' ) {
   $s(l_cal_end_date_field,$v('p_calendar_end_date'));
// create and apex.ajax.widget object
var a = new apex.ajax.widget('calendar',function(){
/* start the return function */
if(p.readyState == 1){
   document.body.style.cursor = "wait";
}else if(p.readyState == 2){
}else if(p.readyState == 3){
}else if(p.readyState == 4){
   $x(l_calendar_region).innerHTML = p.responseText ;
   $s(l_cal_date_field,$v('p_calendar_date'));
   if (p_calendar_type == 'C') $s(l_cal_end_date_field,$v('p_calendar_end_date'));
   document.body.style.cursor = "";
/* DO HERE THINGS AFTER CALENDAR REFRESH */
}else{return false;}
// code for next,previous and today
if (p_calendar_type == 'S'){
p_calendar_type = $v('p_calendar_type');
}else{
$s(l_cal_type_field,p_calendar_type);
a.ajax.addParam('p_widget_mod',p_calendar_type);
a.ajax.addParam('p_widget_action',p_calendar_action);
a.ajax.addParam('x01',l_cal_id);
var lDate = (!!p_calendar_date && p_calendar_date !== '')?p_calendar_date:$v(l_cal_date_field);
if (p_calendar_type == 'C') {
var lendDate = (!!p_calendar_end_date && p_calendar_end_date !== '')?p_calendar_end_date:$v(l_cal_end_date_field);
a.ajax.add(l_cal_date_field,lDate);
if (p_calendar_type == 'C') a.ajax.add(l_cal_end_date_field,lendDate);
a.ajax.addParam('x02',lDate);
if (p_calendar_type == 'C') a.ajax.addParam('x05',lendDate);
a.ajax.add(l_cal_type_field,p_calendar_type);
a._get();
</script>Where I have comment *"do here things after calendar refresh"*, you can hook own scripts.
Of course this is not best way, but might help you till ajax calendar support dynamic actions fully

Oracle Apex partial page refresh problem in IE

Hi All,
I'm using a button to refresh a region by enabling ppr .
On click of the button , m redirecting to url and the url target is as follows
javascript:jQuery('#VH_SCROLL_EMP88').trigger('apexrefresh');
Its working fine in firefox and chrome but not in internet explorer. When I click the button in IE I just get the following
[object Object] in the page
When I click back button of browser I'm getting the original page
Please help me to understand and rectify this
Regards
Sasidharan

a) What version of IE are you using, this probably factors greatly in this question
b) If you want to partially page refresh a region, it looks like you're using a sledgehammer when all you need is your clicking finger
- can you create a dynamic action for your button that applies a 'refresh' action to your selected region

Automatic Page Refresh Not Working Correctly

This is Apex 3.2 with no jquery (Theme 15)
I have a background job which is started from an apex page.
Once the job is started the user can view this job via an interactive report.
This report has highlighting and one updateable column.
APEX_ITEM.SELECT_LIST_FROM_LOV(4,a.status,'JOB_STATUS',null,'YES',null,'-Select-') status
I have an application item that the user can set via a select list.
This application item is used to set the page refresh (html page header)
<meta http-equiv="refresh" content="&F270_REFRESH_INTERVAL.">
Once they have set this item, the the page is supposed to be refreshed after so many seconds.
The page seems to be refreshing, as the report highlighting changes and report values change,
but the updateable column value (select list) does not change.
Any ideas much appreciated
Gus

If I use a button to refresh the page, ie submit and branch back to itself, then the report
reflects the changes.
If I put <meta http-equiv="refresh" content="&F270_REFRESH_INTERVAL."> into the page header (to automatically refresh),
then the page refreshes, but the updateable column does not update.
If I look at the page source it says
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
and not
<meta http-equiv="refresh" content="5">
