I am getting a powerserver error when I am updating a datawindow with a package stored procedure in Oracle 19.

My Powerbuilder version is: Appeon Powerbuilder 2021 CloudPro Edition.

Database is Oracle19 64 bit.

When I am updating a datawindow, I am getting the following error message: Object reference not set to an instance of an object.



I hope someone can help me! 

Thank you,

Hi Stephen;

  Looks like the error might indicate a missing DW on the PowerServer side. Check your deployment (compile) and see if there were DW compile errors that prevented a C# DW generation from happening.

Hi Stephen,

It seems that this issue occurred only for a special DataWindow. Right?
