Back Button Functionality

Dear All,
I have developed a Block List ALV Report . In it I have made a Hyperlink on each column of cells. The Requirement for it is to view more details if any value is clicked. So I have called a Classical Output. Till here it is working fine.
Now when I click BACK Button then it is navigating to Selection Screen but it should go to Block List ALV.
I have tried all the methods like by creating PF Status and capturing SY-UCOMM for BACK button.
Please guide me.
Regards,
Bharti Jain

Hi,
How do you call your CLASSICAL OUTPUT? If you used CALL TRANSACTION command,
better used it with SKIP FIRST SCREEN. See the sample below.
SET PARAMETER ID 'AUN' FIELD gt_vbak-vbeln.
CALL TRANSACTION 'VA03' AND SKIP FIRST SCREEN.
Let me know if this work with your requirements.
Thanks,

Re: [iPlanet-JATO] Back Button functionality

Hi Mike,
Our test environment does not include proxy server.

Guys,
Please clarify something for me, the JATO code is commented as follows
protected void addResponseHeaders(RequestContext requestContext)
// These values should make any proxy between the client and
// server avoid caching, and ensure that pages from one user
// can never be seen by another user (if they're cached anyway)
requestContext.getResponse().addHeader("Pragma","no-cache");
requestContext.getResponse().addHeader
("Cache-Control","private");Yet you make no mention of whether your test environment includes a Proxy
Server, or does your browser
go directly to the Application Server's web server?
Can you clarify, please?

Hi,
We observed the following difference in behaviour between JATO pages
and NetD served pages.
We have the following scenario. User will login to the
site. After login he will get a frame set. This frame set has threeframes.
Top and bottom frames are used for navigation (to switch between various
sections on the site.) .The middle frame(main frame) shows the actual
content. When the the frame set gets loaded main frame shows page1. User
will click on a link on page1. Page 2 will be loaded in main frame. Atthis
point if the user clicks on back button , with migrated application(JATO
pages) the following message appears in the main frame.
In Netscape Communicator 4.61 the following message appears in the main
frame :
Data Missing
This document resulted from a POST operation and has expired fromcache.If
you wish you can repost the form data to recreate the document by
presenting the reload button.
In IE 4.72/5.5 the following message appears in the main frame:
Warning : Page has Expired
The page you requested was created using information you submitted in a
form.This page is no longer available.As a security precaution, Internet
Explorer does not automatically resubmit your information for you. To
resubmit your information and view the web page click teh refresh button.
However, in the NetD site page1 will appear in main frame.
How do we mimic the NetD behaviour with the migrated
applications ?
We think the above behaviour with migrated Apps, is due to the
headers that are get set in Application ServletBase , see the following
code snippet :
protected void addResponseHeaders(RequestContext requestContext)
// These values should make any proxy between the client and
// server avoid caching, and ensure that pages from one user
// can never be seen by another user (if they're cached anyway)
requestContext.getResponse().addHeader("Pragma","no-cache");
requestContext.getResponse().addHeader
("Cache-Control","private");
If we comment the above code , we were able to mimic theNetD
behaviour. Are there any alternatives/thoughts on how to mimic the NetD
behaviour ?
Thanks in Advance,
syam&ravi.

OK, here's what I'm trying to do: We have, like you said, a menu
page. The pages that it goes to and the number of links are all
variable and read from the database. In NetD we were able to create
URLs in the form
pgXYZ?SPIDERSESSION=abcd
so this is what I'm trying to replicate here. So the URL that works
is
pgContactUs?GXHC_GX_jst=fc7b7e61662d6164&GXHC_gx_session_id_=cc9c6dfa5
601afa7
which I interpreted to be the equivalent of the old Netd way. Our
javascript also loads other frames of the page in the same manner.
And I believe the URL-rewritten frame sources of a frameset look like
this too.
This all worked except for the timeout problem. In theory we could
rewrite all URLs to go to a handler, but that would be...
inconvenient.

Hi,
You can define your own PF-STATUS and in that assign the function code for BACK button anything except 'BACK'.
The code would somewhat look like this:
SET PF-STATUS 'TEST'.
write : itab-col1,
itab-col2.
in the PF-STATUS 'TEST', assign the function code to BACK button as 'BCK'.
Now in your program you can use the event AT USER-COMMAND.
In this you can handle the functionality of BACK button.
Hope this helps.

Himanshu

BACK button functionality to be changed for custom report in ITS screen

Hi all,
I am working on SRM 5.0 with INTERNAL ITS.I have created a custom report and a transaction code for the same.Now in the SRM Web menu,I have provided a link for this report.
Now i can see all the std menu options like BACK SYSTEM CANCEL as buttons in the web screen.However when i click on the BACK button,it takes me to the SAP EASY ACCESS MENU screen as we see in SAPGUI.
My reqt is that on click of the BACK button,i need to show the HOMEPAGE of the SRM.Is this possible?If so,how?
All inputs will be highly appreciated and rewarded.

Hello!
There are several possibilities how to call transaction:
- You can call it as service (that is what you do when you test it from SICF)
- You can call it through service (or alias) WEBGUI (not using service for the specific transaction to call it)
If you are calling it through WEBGUI then parameter ~SINGLETRANSACTION should be added to service (or alias) of WEBGUI. And there should be added also Log Off URL (in SICF). At this case it should navigate back to the URL which is specified in SICF.
Hope this helps!

Question about back button and Onload function in a jsp

Hi All,
I am having two jsp pages, say a.jsp and b.jsp. I had a javascript onload function which refreshes all the fields in a.jsp. When i enter some values in a.jsp, based on those values i will be getting the results in b.jsp. Now when i click the back button in b.jsp, it will go to a.jsp again. The problem i am facing is when i click this back button, because of the onload function in a.jsp all the fields in a.jsp are getting refreshed but i want the values which i entered previously in that page. Is there a way that i can do this such that the onload function will not run when i come to that jsp by clicking the back button.
Also i would like to know why a.jsp is reloading when we click the back button in b.jsp and coming to a.jsp. Is this way how back button will function. I am not sure of it. Plz clarify my doubts..
Thx.....

Normally it is not advisable to use the browser back button rather if there is a need we should
implement the back button functionality.
For e.g
In b.jsp
<head>
</head>
<script language="Javascript">
function fnBack()
document.frmHeader.action = "a.jsp";
document.frmHeader.submit();
</script>
<form name="frmHeader" method= "post">
<input type="hidden" name="hdCheckFromB" value="Y">
<p>
<input type="button" name="btnBack" value="Back" onClick="javascript:fnBack();">
</p>
</form>
</body>---------------------------------------
Now , in a.jsp
<%
String strBackParameter = requst.getParameter("hdCheckFromB");
%>
// Now if strBackParameter is carrying a value "Y" , then we know its from B else body onLoad refresh-------------------------------------
Hope this helps.
Thanks

Safari 7.0.4 Back button often greyed out.

Since updating to Mavericks and getting Safari 7.0.4 with that, often my Safari back button is greyed out when clicking on a link in a page. When a link opens a new window, of course there will be no back button function for that new window until you click on to another page. That is not the problem. My back button is greyed out often when I click on a link that changes the current window to the new page without giving me a new window. Normal surfing stuff. I have had to use my History dropdown to go back to the previous page.

Delete the cache and troubleshoot Safari extensions and plug-ins...
pen a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Quit and relaunch Safari to test.
If that didn't help, try troubleshooting extensions.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test.
If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.
If it's not an extensions issue, try troubleshooting third party plug-ins.
Back to Safari > Preferences. This time select the Security tab. Deselect: Allow plug-ins. Quit and relaunch Safari to test.
If that made a difference, instructions for troubleshooting plugins here.

Disabling of back button in Oaf

How to diasble the functionality of back button present in Internet explorer?
Thanks in advance

You cannot disable the back button functionality, but can handle the back button clicks on your page.
Please check pageContext.isBackNavigationFired() method. Accordingly there is a class called TransactionUnitHelper which can be used to identify the sequencing of the back button and a decision made accordingly whether you want to continue with the page functionality or show a Stale data page.

I found some articles to solve this. If you see the banking sites like icicibank.com(after loggin in), they followed this concept. Their if the user clicks back button then, it''l say like u've clicked back button or your session is expired. Then it'll ask to relogin again.
please refer this link for further information.

Safari Back Button - Broken Again!!!

In a previous post, http://discussions.apple.com/thread.jspa?messageID=9724856 I was able to restore the back button functionality by doing a complete reset on my 1G iPod after the Safari Back Button became permanently disabled. This happened shortly after upgrading to OS 3.0.
It has now happened again, and this time I know the step that caused it. I was on Wikipedia and clicked a hyperlink to another wiki page. The link generated a 502 Bad Gateway error. At this point, the Safari Back Button became permanently disabled.
I guess I have another full reset to do again.
Marty

After doing another full reset, the Back Button on Safari was activated again. BUT!!! Now after using it for a day, it's gone again!!! Arrrrrrrggggggggggggghhhhhhhhhh!!!!!!
Is there any way of going back to OS 2.x? This never happened over the last 1.5 years of using OS 1.x or 2.x on my 1G iPod Touch.

Back button is premanently greyed-out and non-functional

I have tried all of the suggested fixes: disabling add-ons and extensions, deleting and re-installing the program, etc... but the back button remains non-functional, even on safe mode and after the last few updates. I cannot use the browser until this problem is fixed, and will continue to use Chrome until it is (even though I hate it and really miss Firefox). Funny thing is, it only happens on my Macbook Pro, running the latest version of Snow Leopard... it doesn't happen on my i7 iMac, running the same version of Snow Leopard.
Any help would be greatly appreciated.
Thanks, and have a great day,
-Jim

Hi,
Check the Font AppleGothic.ttf is active and validates using the Font Book app.
if you have to change anything restart the Mac.
If this is not the issue go to ~/Library/Preferences and find com.apple.ichat.plist and Drag it to the Trash and then restart Messages.
The above reply in another thread solved my issue! Namely that my apple gothic font was disabled, breaking the entire Messages app.

Disable Default function of "Back" button for Android.

Hi there!
I have tried SO MANY methods to PREVENT the default function of Back button in Android but no success
This is one of the codes I have used with no success:
stage.addEventListener(KeyboardEvent.KEY_UP, optionsKey, false, 0, true);
function optionsKey(ke:KeyboardEvent):void
      if (ke.keyCode == Keyboard.BACK)
            ke.preventDefault();
            ke.stopImmediatePropagation();
          //Do my own code below...
I am using Flash Cs6 , Air 3.2 for Android , Testing it on LG Google nexus 4.
When I use the flash simulator, it works fine! Means the Back Button, let the App go back to previous step (as I expect it to do)
But after I publish the apk (Aspect ratio: Auto , Auto orientation , Render mode: GPU), as soon as I press BACK, it minimize my app!
(means when i press the Back button on my phone, the App minimize down (not close!). when I re-activate it/click on it, I see the app has actually gone one step BACK (as I programmed and expected), but I just CANT STOP the default action of MINIMIZING/De-activating my app after pressing Back button.
Anyone have any "Fla" file that I can see it in ACTION please?!
Because I have used many-many codes and no success yet
thanks and looking forward for your any kind of hlep...
