In XPages Mobile App, can you clear viewScope variables between page changes?

Question

I'm working on an XPages Mobile app using mobile controls from Extension Library.

My hope page is a menu leading to 4 different mobilePages.

I get this this is 1 XPage and we're dealing with "Virtual Pages". But is there a way to clear viewScope variables and document bindings as you go back and forth between virtual pages?

For instance. In one of my pages I ask the user for some data. 3 Fields stored in viewScope Variables. Using that I then have a button to Create a new document which gets bound to a panel and then I do things with it.

If the user hits "back" from the menu bar, to go to the Home screen and then goes back to the same page I want to clear everything and start all over.

setting resetContent= true doesn't do anything here.

My virtual page is a custom control and I tried to clear everything on beforePageLoad but that wiped it all during a manual refresh.

I tried hooking into the rendered property of the back button but that fired during a full page refresh. Possibly I could live with partial refreshes but someone might still manually refresh it.

Any way to get this ability inside the single page app mobile context?

Thanks!

See the following XSnippet on OpenNTF.org for your answer and a worked example - have fun! BTW: this is something we want to support on the Mobile App Page in an upcoming release - for now you can use the worked example I provide on XSnippets!

Have you tried using requestScope for the virtual page bindings? From your description, it sounds like this would be the correct scope to use.
