Hi Tom

When you refer "back button" are you talking about browser back button, or is it a link in your web application?

I think the back button form browser, preserves the last fetched list. In the case of an application link, you can add a boolean input parameter to your scren, that is filled with true, when you click in back link.

I have the same question as Tom.

For clarity:

I have a page https://www.temples.co.uk/ if you type some numbers in the min and max price and press Search you will go to the next page as expected. If on this page you alter the values the search is executed as expected (onChange).... but if you press the browser back button the old min and max values are presented - not the new session variables.... how can I force this screen to refresh to display the session vars?

Thanks

Gary

What I ultimately ended up doing, though I don't recall where I found it to add a link to it, was the following:

1. Add a textbox in a container with Display = false, tied to a text variable on the screen
   1. The variable is defaulted to "No"
2. Added an onload extended property to the screen, with the following javascript

   1. "$('#" + Refresh.Id +"').val() == 'yes' ? location.reload(true) : $('#" + Refresh.Id +"').val('yes'); return false;"

3. This will cause the screen to reload if the back button is pushed, by setting reload to yes on the initial load, and then if the back button is used, when the screen is reached again, will trigger the reload
   1. This does have the drawback of causing the screen to reload.  For what I was doing, it wasn't an issue.

I think Thomas solution is roughly the same as :
