I have a piece of PowerBuilder 7 code used to highlight (mark in red) error rows on each textbox in a DataWindow by changing the background.color property through the Modify() command.

When running this code on PowerBuilder 2022 R3, I perform the following steps:

  1. On the input form, a textbox contains an invalid value that does not pass validation; I press submit.
  2. Result: All textboxes with validation errors are highlighted (in red) as expected.
  3. However, when I correct the value in the textbox that was previously highlighted red (i.e., change the invalid value to another incorrect value), then:
    • The red highlight disappears, leaving only a slightly red underline.
    • The textbox content cannot be edited further, as if the application has frozen.

My questions are:

  • Does this code need to be modified to work stably on PowerBuilder 2022 R3?
  • What causes the above phenomenon and how can it be fixed?

Thank you very much for your support!

The text data type cannot be selected as DISTINCT because it... From a solution, edit objects in a PBL.
