With this, I am able to populate the sportName enum values correctly in drop down for example when I select product group = 'A' , I see A1, A2 , A3 in sport name drop down. but when I select a different value in product group for ex. 'B' it gives the following error:
Value 'A2' is not valid for enumeration 'sportNameB (nms:operation:sportNameB)'.
I also tried using "If" expression in the form but unable to get rid of the error.
