Using back button to correct form mistakes?

I have a form for people to update their contact information
on a site. It has client side form validation but in some cases I
generate a message after the fact that something is wrong (for
example when the image verification key is wrong). I have a message
that says to click the back button on your browser to correct your
mistake. Is this an acceptable solution or could something
potentially go wrong? I've tried it on a few computers and browsers
with no problems.

I also do that from time to time. If you want to be thorough,
on Windows machines, alt-left arrow does the same thing.

Active Focal Point Not Shown in Software Using Back Button Focus

I use Back Button Focus (BBF) and set the focus point (using center spot).
In the software (DPP, ZoomBrowser or EOS Utility) the point I selected is not highlighted in the view window.
All points are shown, but none highlighted.
If I take the same shot using default focus method (shutter button AF), the point is highlighted .
Why is this?
Not too technical, please

Thanks.
I did just download and install the updates (DPP, EOS, Picture Style Editor and Zoom Browser).
Still no red focus point(s) shown with Back-button Focusing.
I searched on the web for this "symptom" and found, that I'm not alone.
It seems in Back-Button Focusing, the focus point won't be displayed unless you hold the back button down (* button in my case) while pressing the shutter button.
I tried holding the * button while taking a shot and yes the red box shows up.
This seems like defeating the usefulness of back button focusing. (???).
What do I know? I'm just a newbie.

Struts : checkbox status is unchanged if i use back button and uncheck it.

hi
I have a couple of checkboxes in a jsp page used in struts framework. I am using DynaValidatorForm as form bean with session scope, so it means the properties are mapped only in the struts-config.xml. the checkboxes' property names are checkbox1 and checkbox2.
now the in the action class, i do:
public ActionForward execute(ActionMapping mapping,
            ActionForm form,
            HttpServletRequest request,
            HttpServletResponse response)
     throws Exception {
          DynaValidatorForm dynaform = (DynaValidatorForm)form;
                                          System.out.println("1st checkbox value:"+ dynaform.get("checkbox1") );
                                          System.out.println("2nd checkbox value:"+ dynaform.get("checkbox2") );
}Now if I check the first checkbox and press on submit button, the action class prints out:
1st checkbox value: on
2nd checkbox value: off
this is as expected
Now I click on the back button, then i uncheck the first checkbox and click on submit.
the output is same as before, i.e.:
1st checkbox value: on //wrong
2nd checkbox value: off
I expected it to be
1st checkbox value: off
2nd checkbox value: off
That means if in a session if i check on checkbox 'on', and i go back and uncheck it, the uncheck is never stored, i.e. the property is never set to 'off' .
Now if i check the second one, and click on submit, output is :
1st checkbox value: on //expected off
2nd checkbox value: on //correct
now i go back and uncheck the 2nd checkbox (the first checkbox is already unchecked before), click submit and i get this output:
1st checkbox value: on //expected off
2nd checkbox value: on //expected off
Please let me know what is happening. I expect the values of uncheck boxes to be 'off'
thanks

The String[] thing is only useful when you have multiple checkboxes of the same name.
What is the scope of the form bean? Request or session? If it's request, then that makes no sense. If it's session, then it does make sense because the same bean is being used, and as a result, the values are not really reset. And since HTML forms work by not submitting anything for unchecked checkboxes, then the server doesn't get anything in the request form data to know to change the checkbox to any other value.
If you are using session scope, then make sure you have a good reason to. Otherwise, use request.

Using Back Button after Display Report

Hi,
Need an advice, i need to customize the standard BACK button after report had been displayed, trying to use AT USER-COMMAND, but still not avail..
anyone can come with example will help me a lot.
Thanks

Hi badz lee,
Just change the function code 'BACK' to 'ZBACK' in your custom GUI staus.
Then write your own logic for the custmer needs.
Hope this code helps.

Text Click box not working when using back button on playbar

I have an interstesting situation.
I have a slide that has 2 text clickboxes (Slide B)
Each text click box has an advanced action associated that controls what is displayed on the next slide (Slide C) . The click boxes and the advanced actions work just fine except for the following situation:
The learner is on Slide C and uses the 'back button' on the playbar to return to the slide where the two text click boxes are (Slide B), then the click boxes don't seem to work.
However if the learner goes back one additional slide, the slide before slide B (let's call that one slide A) and the continues from Slide A to Slide B, then the click boxes on Slide B work again.
Can't figure out why that is?
has anyone come across this issue before?

Not for native Captivate interactive objects that suffer with this limitation. There are interactive widgets such as the Infosemantics Event Handler that have preference options to Reset Success/Fail Criteria After Action.
You could download a trial version and give that a go:

You can attach this widget to any kind of screen object to make that object interactive.

Using back button to clear data

I have a several JSP pages that help create a report. The first page you choose some options using check boxes. The second page you put those options in a certain order. The last page you choose the data you want to search for and it runs the report. The second and the last pages have a back button. The problem is when you use the back button and change some of your choices the old choices don't always go away. What I need to do is erase the previous choice (which are contained in an array) when the back button is clicked.
One problem is that the array is declared in a different method than the one that determines what happens when the back button is pressed.

You can use reset funcyion to clear data on back button.

Making sure you can't use back button to go back to a secure page

I am wondering how I can go about ensuring that the user of my application can not use the back button to go back to a secure page after leaving it.
What is the easiest way to implement this added security?
Thank you.

I think the easiest way would be to put in a javascript that opens a page of your choice (such as the home page of a site, for example) and another javascript that closes the browser window. You can get the new window script by clicking here. I'm not sure about the close browser window javascript, but I know that there is a close browser (kills the whole browser, and all the open windows) available here, but that may be a bit overkill. I think you could redo the javascript on the first one so it says something like close_window , but I'm new to javascript and wouldn't know for sure...
Hope this helps!

Can't navigate using back button from web gallery linked to iweb page

I have a web gallery that I enabled as a hyperlink to my iweb site. When I go to the gallery from a web page, I don't have any problem navigating to the gallery to view photos, but I am unable to navigate back to the web page using the "back" button. Instead I have to relaunch my web page in Safari; otherwise I would be "stuck" on the gallery unable to navigate to other web pages.
Does anyone know how to fix this problem?

Load the gallery in your browser and copy the URL.
Create a text or image link and in the "Link" inspector select it as an eternal link.
Paste the gallery URL into the box and check "Open link in new window".
This way, the gallery window can be opened and closed but your original webpage will remain.

Calling a query ( using a Button or Link) form a WAD application in BW3.5

Hi,
I have build a web application using charts, graphs( involving BW3.5 QUERIES, views) using WAD3.5. I however need a Button or a link( probably command URL) in the application screen, TO CALL a perticular query or view in a separate window. Can anybody suggest how it could be done... I am using the Query Designer and web application designer for 3.5 version.
Thanks

This will do what you need
in your html section of your WAD, add this code and make sure you create a separate template to open when you click this button.
<FORM>
<INPUT onclick="window.location.href='http://YOURSERVERINFORMAATION/sap/bw/BEx?sap-language=EN&bsplanguage=EN&CMD=LDOC&TEMPLATE_ID=O2C_KPI_LEAD_TIME_DOC'" type=button value=YOURDEFINTION> </FORM>
Hope that helps.
thanks.

FF always goes back to top of page after using back button. can i disable this?

is there a way to disable FFox going to the top of the site after i use the back button?
If i am on a site and i click on a link then i use the back button, it always goes to the top of the screen or site, then i have to scroll all the way down again every time.

I also have had the same problem for months now. The updates do not fix the problem. Is there anyone out there with an answer?
Sometimes out of the blue I will click somewhere on the itunes store screen and it will stop doing it but, I can't repeat it the next time I open Itunes. It always just wants to stay scrolled all the way to the top on every itunes store page.

Ho to back on selection screen using BACK button

Salute.
I have a program which contains 3 screens:
1st -- selection screen.
2nd -- my screen, I called it 1002, When I press F8 button on I get on it. I am using cl_gui_alv_grid there with my own buttons. So when I press MY OWN the save button I get the 3d screen
3d -- my own screen with some labels (screen name 1001).
So when i press BACK button on the third screen I want to back on selection screen and skip second screen, but I can't, I think the problem is in the cl_gui_alv_grid because I use custom grid handler:
METHOD handle_user_command.
    DATA :
        ls_selected TYPE lvc_s_roid,
        lt_selected TYPE lvc_t_roid.
    CASE e_ucomm.
      WHEN 'QSAVE'.
        PERFORM save_data.
        CALL SCREEN 1001.
      WHEN OTHERS.
    ENDCASE.
ENDMETHOD.                    "handle_user_command
Thank You.

Hi Kernal,
To go back to the First Screen (Selection Scree) use
LEAVE TO SCREEN 0. " This makes the Program to go back from where it had started
or Create a Tcode for your program
CASE e_ucomm.
WHEN 'BACK'.
LEAVE TO TRANSACTION 'YOUR TCODE HERE' . " This will take you back to your Selection Screen
WHEN 'QSAVE'.
PERFORM save_data.
CALL SCREEN 1001.
WHEN OTHERS.
ENDCASE.

Problem Using Back Button in IE When Viewing PDFs with Acrobat Pro

I have an administrative page on my website where I view PDFs of form data submitted by my clients. It has worked fine all along, but suddenly a problem. When I view a PDF, I could always hit the back button and it would take me to the Administrative Interface (of all of my forms). BUT now if I hit the back button it takes me right back to the same form (page) I'm viewing. Below if the Administrative Interface....It may be hard to see but on the left side is a link for the PDFs of available forms. Clicking on the link opens the form...but again when I then click back I'm supposed to return to this administrative page...but instead back viewing the exact same form. HELP!

How do I do the PDF View Previous if the PDF is opening in a browser window in IE?
