Painful Problems of JSF: Back Button

(copy fom theserverside.com)
1. Take guessNumber example
2. Set javax.faces.STATE_SAVING_METHOD=server (default value, BTW)
3. Launch example
4. Click Submit
5. Click Browser Back Button
So far, so good.
6. Click Submit
No action (page is refreshed)
7. Click Submit again
Now, "Sorry" page is shown
8. Click Browser Back Button
No action (page is refreshed)
9. Click Browser Back Button again
We are back!
P.S. Internet Explorer 6.0 has been used for this test.
P.P.S. STATE_SAVING_METHOD=client forces to send several KB to the client each time. I disbelieve that developers will be happy to use this method.

For webapp with tens of thousands of simultaneous users, STATE_SAVING_METHOD=client is converted to dramatically traffic increase. According to specification, the FacesContext is Serialized. What will be a usual size of FacesContext for real application? Not just a 4Kb, I guess. So, we can say about extra tens or hundreds Kb per client and several GBytes per server. Probably, network hardware salesmen will be happy, but I am not so sure about dialup users.
Actually, this option causes some other problems than just a traffic size.
For HTML browsers, there is only one way exists to store and than send the saved data back to the server with the next request. It is an HTML form (if we speak about 4Kb and above). So, it forces developers to use only form to make a request to server. Just a hyperlink is not suitable.
JSF-RI provides two major ways to submit the form - command button and command link. How we can see, h:command_link is rendering to construction .... It causes another problem - browser with turned off Javascript is not supported from this point.
For non-HTML clients (For example, mobile devices). They might not accept to store several Kb. Memory size is a critical issue for some of them.
Of course, it is up to developers to use client as a method to saving View or not. I just guess, that this method will not be so popular as it seems.
Actually, the primary problem means that back button does not work equal for both method. It is not OK.

Problem with the back button in the Alv ouput

i have refresh button in output of my alv report when i click on this it is getting refreshed ,now the problem is with the back button after refresh whn i click on back button it is not going to selection screen , i have to click the back button thrice to come out to the selection screen ,if have refreshed the ouput screen twice .
if i dont refresh the back button is working fine , So i have used "call to selection screen 1000" it coming to selection screen without any problem but in selection screen on clicking on back button it is again going back to output screen ,So please suggest what has to be done here .

Hi Brahmananda,
Please try to understand the flow of program and the screen navigation
the click of BACK button triggers PAI and (to the best of my knowledge) you might have called the ALV screen number without any checks ( may be) so it is again taking to the ALV.
try using
in PAI
module exit at exit-command
in program
module exit
case ok_code
when 'BACK'.
LEAVE PROGRAM ( or any thing that you want it to be )
endcase
endmodule

Problem with Back button in Top Level Navigation

Hi all,
We are facing a minor problem with the Back button in the Top Level Navigation in Portal. This button is present under the Roles and Worksets menu along with the History, Forward, and Add to Portal Favorites links.
The problem is faced when we have some worksets under a single role. While browsing accross these worksets by randomly clicking on them, we wish to use the Back button as well to go back to the previous workset. But when we use the Back button, the Detailed Navigation panel in the last workset is not retrieved.
I will explain with the System Administration Role. I open the worksets under this role in the following manner:
First I open Transport;
Next I open Portal Display;
Next I open System Configuration;
Now I wish to go back to Portal Display workset by clicking on the Back button. But when I do this, although the Portal Display workset opens up, but I cannot see the Detailed Navigation Panel. See the screenshot below:
http://img399.imageshack.us/my.php?image=backbuttonkg6.jpg
Please help me in solving this issue.
Regards,
Ankur

I think I have found a resolution, although not very pleasant:

Back Button not working in FireFox 4

Is anyone else having trouble with the back and forward buttons not working in FireFox 4? I installed 4 on an XP desktop and a Vista 64 laptop, and the forward and back buttons don't work on either installation. Does anyone know a fix for this? I tried deleting the "places" files in the profile and that does not help.

I am having a problem with the back button also in Firefox 4. Firefox forgets the 1st page in any new session or tab. If I open a tab to say bbc.com and navigate to guardian.com I can't click the back button to get back to bbc.com.

Ff22 has two top bars, both of which act simultaneously in the identical way. Furthermore, the BACK button doesn't light up on many web pages. That means I cann

Problem #1.
The first top bar has a firefox logo at upper left corner and the words "Ask a Question/Mozilla Support-Mozilla Firefox" are on the logo's right side. The first top bar has minimize, overlap and close buttons at the upper right corner. When I click on the logo, a short menu drops from it, which has choices like "restore"..."close".
The second top bar has the word "Firefox" at the upper left corner with a downward arrow beside it. They look like white letters contrast to the orange background of a huge button. When I click on it, a double paned menu shows up. It has many choices such as new tab, new private window...bookmarks, history, download...exit. The second top bar also has minimize, overlap and close buttons at the upper right corner, too. There are 7 word titles "file, edit, view, history, bookmarks, tools and help" below that huge orange button at the upper left corner. The logos and the address bar are below the 7 words.
I don't need 2 top bars. They occupy too much screen property.
Problem #2
The BACK button doesn't light up and cannot work on many web pages.
Thank you

It sounds like there is either an application or an extension of Firefox that is causing this problem.
You can launch Firefox in Safe mode to try and identify problems: http://mzl.la/MwuO4X

Additionally, you can try and do a soft reset of Firefox if you are not able to solve this problem: http://mzl.la/MnSTZB

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.

No back button function in Metalink?

Hi.
Does anyone have a problem with the back button on the (Flash) Metalink?
Any work-arounds for this please, other than going to the non-flash html site instead.

Sometimes my back button is greyed out and does not show the previous page i was just looking at!?

This randomly happens and i can not tell exactly what i do or why.
All i know is that every time you visit a page,site, picture etc... the back button remembers every page you have just been too in that session.
However some times the back button goes grey and i can not click on it and it loses all the previous pages i have been to.
I can reopen the last pages by going to my history but it's really annoying as it takes time and as i surf and look at a lot of things, the back button is crucial for me.

I am experiencing the same problem with the back button randomly being greyed out and not functional. If I navigate to the same page a second time, the back button is usually functional again... have not been able to associate this behavior with any particular site

AppBuilder - Back button

Hi guys, Hi Pavel, Hi Midhun,
I'm having a problem with the "Back" button.
It's there because on each page I've activated the "showNavButton" option.But the thing is ... it doesn't work, nothing happens.
I didn't modify the default function "backBtnTap: function() ":
backBtnTap: function() {
var bus = sap.ui.getCore().getEventBus();
bus.publish("nav", "back");
Anyone has a clue?
Thanks,
Marius.

Yeah Pavel,
the only thing I had to add to my page.view.html was in the "Events" tab, there is the "navButtonPress" or "navButtonTap". I had to assign the function that already exists "backBtnTap" to one of those declarations, and everything worked just fine.
Thanks,
Marius

ITunes Store Back Button

When shopping in the iTunes Store, I'm having a problem with the back button or back swipe on my mouse.
It seems only to happen when I've done a search.
For example, If I search for "Horror" it brings me to "Showing Results," which includes Apps, Books, Movies, etc. I then scroll down to "Books" and select "See All." if I select a specific title to read the description, and then try to go back, it brings me all the way back to the "Showing Results" list, rather than the "See All" list. This can become extremely annoying after shopping for a while.
Is there any way to go back to the "See All" list instead? Perhaps a combination of keys?
Thanks for any help.

I agree and just sent this as feedback. iTunes 10 would not only go back to the See All, but would take you to the row of your last selection. This curent version is driving me crazy when looking for apps.
