Back Button Breaks My Layout

Hi All,
I am having a problem with the browse back button, from searching the forums I gather that this is a common problem but I can't find any references to my particular problem?
Anyway, my problem is that when a user clicks the back button the layout of my page is broken. everything seems to operate correctly but table widths are changed and images are shifted. The results are pretty consistent in that it behave the same way for every back button press, ie. the same tables and iamges get shifted?
Any thoughts?
I am using Jdeveloper 10.1.3.4, Oracle ADF Faces components and mostly <afh:tableLayout> for my layout which is a pain by the way, why can't I just have a simple <div>...
Thanks
Jeremy

I am using Jdeveloper 10.1.3.4, Oracle ADF Faces componentsSorry, no experience with it. All I know is that Oracle also has its own forum. Consider reposting this question over there if you don´t get much more response here. At least I haven´t seen any Oracle guys walking around here lately.
and mostly <afh:tableLayout> for my layout which is a pain by the way, why can't I just have a simple <div>...You can just use HTML in a JSF page? Or are you still sticking into JSF 1.1 or older?
Since 2006 there was JSF 1.2 which has a changed view state management and just allows plain vanilla HTML in the JSF page. Before in JSF 1.1 or older you had to nest plain vanilla HTML in a <f:verbatim> tag to let it been taken in the JSF component tree. Besides, since JSF 1.2 the h:panelGroup got a new 'layout' attribute which you can set to "block" to let it render a <div> instead of a <span>.

Using "back" button breaks sample "play" buttons

In iTunes 10.2.2 Mac, the sample "play" buttons in the iTunes Store stop working if you hit the "back" button to return to previous pages (unless you force them to reload).
Is there a simple way to submit a minor bug report like this, when I otherwise do not really need specific help or a response?

It seems that in IE9 if you switch to compatibility mode, the problem goes away. Switch back it reappears.
I have a website about to be released that has this problem throughout. Please let me know if there is a solution.
Thanks,

Browser 'back' button breaks flash file (firefox)

Hey!
I've run into a frustrating problem. I've created a web app for a customer (link here), but whenever I leave the page using one of the map pins and try to return using the back button - the map pins become unresponsive and the hover-state freezes. If I reload the page it works again.
I've only encountered this problem in Firefox, and I believe that it's got something to do with the firefox focus. If I click outside the flash movie, deselecting the flash selection box - the buttons become responsive again.
I've tried looking through the FAQ and it seems as if I've got the exact same problem as these users;

There's a messy workaround using jquery to select another object on page reload but that doesn't look very professional, my customer's also supposed to integrate the .swf with a cms and I'm not sure if I can get it to work.
I use Firefox 15.0.1 and Flash Player 11.4
Any pointers would be very appreciated

FF 15.0.1 with the latest FP installed and my back button works perfectly fine. The pins do not require me to reload the page to work.
It's not uncommon for a browser to require a plugin like flash to be "activated" for focus. Click doesn't typically suffer from this (and isn't for me). Keyboard however, well that makes sense. The ability to auto-activate and steal keyboard focus would introduce usability and security issues.

I hate the update of the bar. It has totally done away with being able to skip back several places in the browser; now I can only click the back button and go back one page at a time. I otherwise hate the new layout, too. How do I undo this?

I can't choose a specific page to skip back to but must click the back button over and over to get back to where I want to skip to. The little headings "most visited," "getting started," "Youtube," etc. have changed. They look more colorful, but I hate how the home button is clear over to the right side of the page, etc. What was wrong with the way everything was before? I HATE this new update, and I didn't even want it.

You can get the drop down list by either right-clicking on the back/forward buttons, or holding down the left button until the list appears.
If you want the drop-down arrow you can add it with the Back/forward dropmarker add-on - https://addons.mozilla.org/firefox/addon/backforward-dropmarker

How can i create forward and back buttons for a dreamweaver slideshow?

Hi
I am an illustrator attempting to create a website in dreamweaver (basically it will be an online portfolio). I would like to have a box/slideshow with images of my work that someone can browse through by clicking 'next' and 'back' buttons. Does anyone know how to do this? I have been trying to find out how to do this for ages - i dont want to use flash if possible as i am worried about making the site too complicated. I know how to make swap image thumbnails, but i think my site would be more user friendly (and look more professional) if i could have next and back buttons. Would this involve complicated css code (which scares the life out of me!) or is there a relatively easy way to do it? I have got two 'dreamweaver for idiots' books, but neither of them cover this topic. Can anyone help?

If you are using CS4, there is a Command to create a Web Album... this does it automatically for you.
Otherwise, you can create this manually. Say you have 3 pages,
page1.html (is the index page of the album)
page2.html
page3.html
Therefore, using ordinary text links
Home would link to page1.html
Previous would link to page3.html
Next would link to page2.html
You would need to make adjustments naturally to each page as you move along with the gallery pages, changing the previous and the next links as needed. Below is a a basic example of setting up the links in a simple table structure. You would also then style the table layout as you see fit - yes, using css preferably :-)
<table>
<tr>
<td><h2>MY GALLERY OF PHOTOS</h2>
<a href="page3.html">Previous</a> | <a href="index.html">Home</a> | <a href="page2.html">Next</a>
</td>
</tr>
<tr>
<td>
<br>
<a href="../images/img_2401_jpg.jpg"><img src="../images/img_2401_jpg.jpg" border=0></a><br>
</td>
</tr>
</table>
Here's an article on creating an album using the DW Command I mentioned earlier. You could create the album and then copy and paste the code into a current page if you've already designed on.,... not too difficult, I just tested it. You do however, need to have Fireworks to process the images.
http://livedocs.adobe.com/en_US/Dreamweaver/9.0/help.html?content=WSc78c5058ca073340dcda91 10b1f693f21-7ad1.html
You could also check out the Lightbox effect which is very popular:
http://www.lokeshdhakar.com/projects/lightbox2/
Or do a google search for 'jquery'. There are different album effects using that framework as well.
Hope some of this helps :-)

In the new Firefox, I have no back button, no "most frequently visited" and there is no longer an option to save tabs when I close.

Many features have disappeared. There is no back button to go to the previous page. There is no "most frequently visited" icon on the toolbar. I am not asked if I want to save all my tabs when I close firefox. There is no recently bookmarked tab on the toolbar. Everything takes longer to get to. The tabs don't automatically stay open.

Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session.<br />
You can use "Firefox > History > Restore Previous Session" to get the previous session at any time.<br />
There is also a "Restore Previous Session" button on the default <b>about:home</b> Home page.
Another possibility is to use:
* [http://kb.mozillazine.org/Menu_differences Firefox (Tools) > Options] > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"
Do you still have the Bookmarks Toolbar visible?
* [[Restore the default Smart Bookmarks Folders]]
Check that you still have the "Bookmarks Toolbar items" placed on the Bookmarks Toolbar
If the menu bar is hidden then press F10 or hold down the Alt key, that should make the "Menu Bar" appear
Make sure that you have the Bookmarks Toolbar and the Navigation Toolbar visible: "View > Toolbars"
Open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout"
* Check in "View > Toolbars > Customize" that the "Bookmarks Toolbar items" is on the Bookmarks Toolbar
* If the "Bookmarks Toolbar items" is not on the Bookmarks Toolbar then drag it back from the Customize window onto the Bookmarks Toolbar
* If you do not see the "Bookmarks Toolbar items" or other items that are missing in the toolbar palette or on a toolbar then click the "Restore Default Set" button

Back Button Doesn't Work on Some Websites

How come my Back Button Doesn't Work on Some Websites? It just keeps redisplaying the same page over and over. Example:
http://abclocal.go.com/wabc/front

Back button behaviour can be pretty wierd. I usually use the keyboard combination, but for some reason it doesn't work on PDF's and I have to end up using the graphical back button.
There are some websites out there that for some reason or another break the Back button's behaviour. Sometimes I have to hold down the mouse button to get the back button menu in order to work around that problem.
In another case there was this page in Amazon that wouldn't allow me to go back to. Everytime I went to that page the browser to automatically kick me to the next page. I had to disable javascript to work around that problem.

Report S_PL0_86000030 - G/L Account Balance - Back button Issue

Hi
We are on ECC 5.0 and when we click on the BACK button, from the report display it straight way goes back to SAP standard screen (both when we save or do not). It does not go back to the selection screen of the report.
I searched OSS and could not find any possible resolution.
Could anybody know how this can be fixed? Any patch?
Thanks,
Surajit

This can be achieved by clicking on Characterstic Key & Name - both option under Settings --> Characterstic Display (you can get these options if you run the report under Classical Drilldown mode)
Also if you can just change the same thing in the report layout - it will be permanent - Transaction FGI0.
Thanks,
Surajit

Having issues with longMessage and back button usage

Hello,
I have part of an app that consists of 2 pages. The first page is a set of checkboxes and an Analyze (submit) button. when the user hits Analyze, I commit the transaction and forward to the second page which displays the checkboxes they checked and some other information regarding those choices. If a user wants to change their answers, they use the browser's back button and change their choices, then click Analyze again. This is working fine.
I now want to add a longMessage to each checkbox above with some additional information about each choice. I've setup these up and they work fine; the dialog box launches just fine when they click the little (i) icon.
So that's the status quo; here's my problem:
Scenario
1. User clicks one of the longMessage icons
2. clears that box by clicking OK
3. then hits Analyze to progress to the second page
4. now user hits browser's Back button to go back to questions
5. PROBLEM
At this point, all my checkboxes are blank. If I try to re-check one and hit Analyze, I get an error stating "No current row for View (XXXLProcNavVO1)"
If I don't ever click a longMessage icon, everything works fine. I can only replicate this if I follow the exact steps in the scenario.
So what is wrong? Why am I losing my current row in my VO when I use the longMessage?
I've included my CO from page 1 for reference below.
Thanks!

Back button doesn't work in https google search

Google search seems to have made https mandatory when logged in. This breaks history and the behaviour of the back button from the results page back to the google search results page. I think that this is because google, upon clicking on a result link, redirects to the results page via an intermediary, obfuscated url, which causes the back button to also redirect back to the result page. This is exactly the same problem as described here: https://support.mozilla.org/en-US/questions/892406?e=es&as=aaq for which there is no solution, as google doesn't allow us to disable https anymore. BTW, this behaviour is not replicted on chrome, i.e., back button works correctly in spite of the intermediate redirecting page.

Hi,

How do I go back to the previous page if the app dosen't have a back button?

In iOS we can go to the previous activity of an app by swiping from left to right of the screen. In FireFox OS is there any way to go to the previous page of an app?

Hello,
Depending on the app it should have its own back button. Could you let me know which app you are having trouble with?
I've attached a screenshot of the Settings app in Firefox OS. The screen shows the Sound settings page. If you wanted to go back to the main screen of the Settings app you would click on the back button in the top left hand corner. It looks like this: <
Some apps (e.g. from the adaptive app search screen) may not have a back button built into the app itself. In that case you can access a back button from the navigation bar at the bottom.
I've attached another screenshot from the IMDB app. Here I have accessed the 'Breaking Bad' page. If I want to return to the previous screen I can swipe up from off the screen over the orange button in the bottom right hand corner. It looks like this: ᶺ
Then the navigation bar will appear (see my 3rd screenshot). The back button is on the far left side of the navigation bar. It looks like this: ←
I hope this helps. Let me know if not.
