Combo box not saving last selection in v8.1

Not sure what's going on, but this was the text Ryan was trying to post:

Thanks for the replies. Here's what I've found in my testing. Please let me know if you see the same:

Create:

1. A basic Time Member list Parameter with T#2023.Base in it.
2. A basic Combo Box Referencing the time parameter.
3. A basic uniform dashboard with the combo box component in it from step 2. (let's call it "Nav Combo Boxes Test")

Result: This combo box on the dashboard works just fine and saves the selection as expected. You can close (x) out of the Dashboard and re-run it and it'll still save the selection.

Next Create:

1. A button and make the navigation action "Open Page" with the argument “XFPage=Dashboard:Nav Combo Boxes Test”
2. Add the button to a new dashboard (call this “Button Dashboard”
3. Run the Button Dashboard and click the button that brings you to the Nav Combo Boxes Test dashboard
1. Change the time selection
4. Re- Run the Button Dashboard and click the button that brings you to the Nav Combo Boxes Test dashboard
5. Notice the selection is back to the default, not whatever you changed it to in step 3.a

Result: The combo box breaks when you link to the dashboard from a button. The combo boxes save selections just fine until you navigate to the dashboard via a button.
