Creating a customized Cancel Button

Question

I have a page with 2 regions.
The 1st region has several text items and 2 buttons that are displayed conditionally.
When the page first renders, Button A is displayed. The user then enters a value in one of the text items and clicks Button A. This displays the 2nd region. Button A then disappears and Button B appears.
But I want the user to be able to start this process from scratch, i.e., have Button A appear on the form once again, with the form ready for him to enter another value in the text item and click Button A This is essentially just a Cancel button that returns the form back to its original state when the app was first entered.
Can somebody please tell me how to do that?

Hi Prohan
You can add a button to a page that clears the cache of any page. What I think you are asking for is a button on page N that redirects to page N and also clears the cache on page N.
To do this create a new button through the wizard and specify the page to re-direct to as the page you are adding the button to. When you've created the button you'll also have a branch created on this page for the button. Select the branch and in the Clear Cache section enter your page number.
Alternatively, if you only want to clear some of the items on the page then create the button as above and leave the Clear Cache field empty. Instead enter the fields you want to clear in the 'Set these items' field and only enter comma's in the 'With these values' field. For example, to only clear fields 1, 2 and 3 enter
Set these values - P1_ITEM1, P1_ITEM2, P1_ITEM3
With these values - ,,
Hope this helps.
