i checked few senarios and my findings,
1. this issue not happening at change REST URL action. it happens at Query REST Data Connection action.
2. when form loads, data is pulled from REST URL from data connection and able to show in multi select list box by binding.
3. when user first time changes drop down, page refreshes and new selected value is not beeing in dropdown. when user again changes dropdwon, then this error message occures.
----
if there is no solution or fix for this, i would like to know how to use "Query data on SP List" method that you suggested above for fulfilling my requirement.
thank you very very much for your help.
