Named Query binding not working

Named query update binding not working. Select binding is working. Manually, named query update binding working but bind to component then not working.

Is Load_Num really a string column? If not, change the Named Query’s data type for the :LoadNumber parameter.

Load_Num is string.

I observed that same named query is working on property change event
(Named query changed slightly to add column name in query)

Hence thought that the “Text Field” value change event is not trigger the Update Query. Also I have checked with 8.0.6 (b2019111216) and observed same issue.
