How2 implement back button

Hi Everyone!
I have a static webpage with a link to an htmldb application (no authentication, just a report).
I would like to create a browser back button in htmldb, that does just this:
onClick="history.back()"
But all created buttons demanded a page (in htmldb - or url) to branch to.
What would be the best way to implement such an back button?
Thanks,
Michael

Hi Michael,
i think your HTMLDB-page is a report. So do the following steps:
1. Create a button
2. Select the region for the button
3. Select "Create a button in a region position"
4. Give the button a name and a label and - that's important - select as action "Redirect to URL without submitting page"
5. On the wizard page for branching select as target "URL" and enter the URL (at the bottom of the page) "javascript:history.back()"
6. Click "Create button"
That's all.

Implementing a "back button" in a JSC project.

I would like to give my use a "back button" that acts like the back button on most browsers.
In other words, add a button to a page and when the user clicks that button, the user will be sent back to the previous page just like if they clicked the back button on the browser.
I assume that this can be done using the onClick Javascript event for the button, but what exactly needs to be done in that method?
I searched the Internet and it looks like something like this might work:
Go back
But how to convert that to JavaScript inside the JSC app I do not know.
Does anyone know how this is done?

Note that I tried adding:
history.back()to the onClick event, but that didn't do anything.
My full page code looks like this:

Back buttons and required fields...how to implement?

Hello
I would like some thoughts on the best approach to the following problem please.
-You have a wizard, lets say made up of 2 pages.
-Page 2 has some required fields.
-User goes from page 1 to page 2 then wants to return to page 1 for whatever reason.
-(Assuming they havent filled in the required components), what is the best way to let the user navigate back to page 1, without the system kicking in its required fields warnings etc..
One option I have thought of is populating the fields myself, but this feels like a hack.
Second option could be to edit the required=#{} of the required components when the back button is pressed?
Any thoughts?
JC.

Good tip.
ok, back to the main thread. immediate = true will result in any data the user entered being forgotten. The solution does by-pass the required rules, so its a mini result.
Tomahawk does have a stateSave component.
<t:saveState id="save" value="#{bean.xxx}" />
And a JavaScipt listener component.. I'm thinking both or one of these could be used to remember/store the state..
If anyone has any other solutions then please post.

Is it possible to invalidate session when I click my browsers back button

Hai
I have a question.
I am building a jsp page with multiple forms.As of now,
no login system has been implemented.
I need my session to time out when the client click on the back
button on the browser to prevent data corruption.
Is there a possible way to do this in Java/ Script
I know the use of session.invalidate() but how to tie it up to the
browser's back button
A second problem
If I use session.invalidate() on Tomcat 3.2
I find that it is not invalidated.But this same function on tomcat 4
doesn't have any problem
Could anyone help on these issues
Thanks

You don't mean you want to invalidate session every time you move to a new page, do you? If you do, after implementation of login system the users will be asked for passwords at each page. If you don't, it's better to use headers for your response.
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Expires", "-1");

Reporting Services add (browser) back button

Dear all,
I have a client that has 4 reports; 1 main, and 3 that are rendered when the user clicks the report data on the main report (which passes parameters to generate the other 3).
They would like to have a back button in the report header of the 3 reports (they don't want to use the browser back button).
Is this possible using a text box, then editing the navigation properties and does anyone have an example? Or am I missing something quite obvious?
Any help would be gratefully received!!
Dan

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!

How to resubmit the form when back button pressed

Hi,
In my application, iam implementing searching,
when i submitting the form, i got some records and i navigated all the results through next and previous buttons.
Problem occurs when i clicked on back button, it is showing "page expires and asking for resubmit the data".
How can i show the previous page, when user clicked on back button.
Iam using struts 1.0 and ibatis
Please help me out.
Thanks in advance,
Mohan

Hi mohan,
try to store your search indices in a vector and put that vector in the session scope. at page first loading you get the first index from your vector and pass it in the request scope in your action class, due to the page you have to find a way to understand the passed index in request scope and translate it to the searched word location.really I have not a code sample, but it is just an idea.
feel free to ask me.
Thanks.

How can I "expire" a web page (prevent BACK button access)

How can I "expire" a web page ?
I know some sites will display the following message if we click on the
BACK button in your browser.
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 this Web page, click the Refresh
button.
How do I implement this feature??

U want to disable back button click
if yes i think
javascript:window.history.forward(1);

    <h:selectManyCheckbox value="#{home.value}">
         <f:selectItems value="#{brandItems}"/>
    </h:selectManyCheckbox>
    <h:commandButton action="#{home.display}" value="Submit" />
    <s:link value="view newxt page" action="#{temp.getAll}" view="/table.xhtml" />
</h:form>2. This is my session bean code
@Stateful
@Name("home")
public class TempAction implements Temp,Serializable
     private static final long serialVersionUID = 1L;
     String []value;
    @Out(required=false)
    List<SelectItem> brandItems;
     @Begin(join=true)
     public void getAll() {
          brandItems=new ArrayList<SelectItem>();
          brandItems.add(new SelectItem("First","First"));
          brandItems.add(new SelectItem("Second","Second"));
     public String[] getValue() {
          return value;
     public void setValue(String[] value) {
          this.value = value;
     public void display() {
          for(String a:value)
               System.out.println("________________"+a);
    @End
    public void reset() {}
    @Destroy
    @Remove
    public void destroy() {}
}3. I invoke getAll method by using following code in my pages.xml
After visiting the second page by clicking the s:link , I go back to the first page by using browser BACK button . Then when I hit the SUBMIT button, I get the following error message in my jboss console and also the check boxs are deselected.

Did you ever find a solution? I'm having this issue also.

How to set a back button to the caller page

Hello,
An application have a page that can be called by several other pages, for instance, an "addContact.faces" can be called by several other forms, when the user adds the contact or press a back button, the application should go back to the caller page.
How can I implent this?
Thanks in advance,
Juan

As an alternative, you could Ajax the stuff and put it in a popup div, which is a common technique nowadays. Then the user doesn't even navigate away from the page he/she was on, plus it is relatively easy to implement in a generic way so multiple pages can use it.
Search for "css popup div" on google if you want to see this in action.

How to call custom BSP application on click of BACK button for SC in EBP.

Hi All,
We are implementing OCI using custom BSP applications.In EBP SC screen ,in step1 (Select Goods/Services), the links for these BSP applications are displayed.
The user can create a shopping cart using these applications , after the items are transfered from BSP to SC on standard EBP screen , in step2
there are four buttons ,
1)Refresh
2)Check
3)Back
4)Continue.
We need to call one of our custom BSP applications on click of this BACK button
How can i acchieve the same?
Do i need to make changes in the standard ITS application or thers some other way?
Thanks,
Anubhav.

To call a wd abap application from BSP use the method CL_WD_UTILITIES=>CONSTRUCT_WD_URL then just create a link in bsp with the url returned like this:
<a href="url">Link</a>
To pass data from wd abap to bsp or vice versa that a look at this blog: /people/koen.labie2/blog/2006/11/29/eating-cookies-with-webdynpro-and-bsp

IPhone: NavigationController Back Button

The back button on a navigationController is supposed to be automatic, right? I have a table view hierarchy with a navigation controller that has two table views. I can click on a cell in the root view and it does the transition to the next view. However, when I click on the "back" button on the navigationController, the navigationController does a transition and displays the title of the root view, but the table view does not change back to the root view. I checked, and the stack still contains two objects after this half-transition. I can call popViewControllerAnimated myself from the second view, but I didn't think this was necessary. Also, I wouldn't know where to Is there some sort of flag I need to set if I want popViewControllerAnimated to be called automatically?
Thank You,
Bridger Maxwell

I have looked through a few examples which use the UINavigationBar, and I can not find any differences between their code and mine. I even used a lot of code directly from one example. It is quite puzzling.
Just so I can check, is there a way to prevent the back button from working by catching a message or something? I found
- (BOOL)navigationBar:(UINavigationBar *)navigationBar shouldPopItem:(UINavigationItem *)item
in the docs as a method you can implement for a UINavigationBarDelegate protocol, but I can't even set the delegate for the UINavigationBar because I am using a UINavigationBarController, and the docs say I should never access the UINavigationBar inside the UINavigationBarController. I am really quite puzzled on this.
Thank You,

Cannot click back button on Internet Explorer,

Dear Sir,
In content Management of EP6 SP14, KM content we cannot click "back button" in IE menu. if we click back , it will show the error.
How to solve this problem.
Thank you and best regards,
Vimol

Hi Vimol,
you can not solve this problem. The browser functions 'back', 'forward' and 'refresh' do not work properly on SAP EP 6. That's why you find the navigation links and the portal history in the portal header.
There is a feature called 'External facing portal' or 'EFP' that solves your issue by rendering one HTML file for every portal page. But you'll have some restrictions concerning business packages, KM and collaboration when using EFP.
There are a lot of threads in SDN about EFP, but here is an entry point:
<a href="http://help.sap.com/saphelp_nw04s/helpdata/en/43/13fd52a5732ba9e10000000a1553f6/frameset.htm">Implementing an external facing portal</a>
Please be aware that EFP comes with NW2004s SPS6
HTH,
Carsten
