This idea is reference of ticket id 01951903 - INPUT VARIABLE EXTENSION RESET TO BLANK OR EMPTY OR DEFAULT VALUE OF VARIABLE AFTER REFRESH.
We have an extension which refresh every minute. We have used input variable extension on one sheet where client enter value(integer) then charts get filtered according the set analysis written on variable attached to input variable extension.
Problem here is let say current time is 12:01:01(hh:mm:ss) and client entered a value suppose 1 into variable extension when app reloads at 12:02:00 the entered value vanishes after refresh and this annoys client because he needs to reenter the value.
Idea or suggestion here is, variable extension should keep value after refresh of app until session expires or user clear the selections.
