Tree picker is not working in reference fieldSummaryThe tree picker is not working in the reference field. It is showing a blank record, it is not highlighting and showing the Hierarchy of Parent-Child.Instructions*The tree picker is not working as expected because of the large amount of data fetched after clicking on the "Parent" reference magnifier. *The only practical thing you can do to improve tree picker performance is to use a reference qualifier to reduce the number of queried records to a number where performance is acceptable, and make sure the system glide.ui.group_heirarchy.max_nodes property is not set too high. There are no hard numbers regarding what values are optimal, it may require experimentation.*If that's not feasible for a specific use case, then the tree picker is not the best option for a reference field lookup and the normal lookup should be used instead.Related LinksPlease refer to the Now Platform user interface documentation for more information about the tree picker.
