Editable column in Repeat Grid appears as read-only



A column in a grid configured as editable appears as read-only. After sorting the grid, the column turns editable.

Error Messages

Not Applicable

Steps to Reproduce

  1. Configure repeat grid with some columns set to be editable.
  2. Run the use case.

Root Cause

The property sourcing the column (for example, ReceiptQty) is the target of a Declare Expression and therefore calculated automatically.


Avoid direct updates to target properties. Do not change the value of a property computed by a Declare Expression rule through the Property-Set method, application of a data transform, or user input into a form. As you develop your application, PRPC attempts to detect and prohibit such situations.

To set the value of the property manually (through activity or data transform) remove, delete, withdraw the Declare Expression. To use the Declare Expression to set the value, configure the property in the grid as read-only.
