HI i have a ExtJS code on the front end. the drop downs on this page are loaded dynamically thru web-service call to 3rd party service. i have navigated from this page to the results page.

Now in results page i have a button which allows the user to go back to previous page. but all the data in the drop down should be retained.

i tried window.history.go(-1) and history.back()

Guys please help me.
