I have 6 multi select lists(Pop Up Lov) to be precise, with parent child relationship.
Let's say, A → B → C → D → E → F, where A is parent of B, B is parent of C and so on.
The parent item is specified in each LOV for cascading.
The issue is, when the user changes value in any of the multi select parent item(let's say, user adds a new value), all the subsequent child items till Item ‘F’ are refreshed and reset to null. Similarly, when the value is removed from a parent item, all the values(even the ones which are valid) are removed as child item is reset to null.
How can I retain the valid values in child items when a change is made in parent items?
