Externally Mapped Property Blank in Database



You have a database table with several extermally mapped properties which are defined on the associated class' "External Mapping" tab. You notice via PRPC trace and database investigation that when doing an Obj-Save coupled to the database table that one or more of the properties is set to null, but at run time values are present on the clipboard.

Error Messages


Steps to Reproduce

  1. Create a Page.
  2. Set all the values over that page.
  3. Check the values are all present on the clipboard
  4. Do an Obj-Save
  5. Check values in DB
  6. All the values are being saved except "Property A"

Root Cause

The root cause of this problem is defect/misconfiguration in the PRPC operating environment. The external column was added after PRPC start up and PRPC does not recognize the database schema change.


This issue is resolved through the following local change: 
Revalidate the class and property of interest and restart the JVM
