Hi Experts,

Issue: Combobox is showing null when reset the options and value variable associated with it

We have a oj-combobox-one with Options set to a variable (optionsLoV) of type Array of Object and Value set to a string variable(valueString). optionsLoV will be fetched from Rest EndPoint(custom - not BusinessObject) on page load

We also have a reset button which on click, performs Reset of both variables linked to this combobox (optionsLoV & valueString). I'm using Reset variables option of action chain.
