Error Messages

** ** @hasMessages(Primary) &amp&#59;&amp&#59; @isPageLocked(tools, Primary) &amp&#59;&amp&#59; Param.bIsModal != true &amp&#59;&amp&#59; param.StreamType!="NO_UI" &amp&#59;&amp&#59; param.Submit_NOUI != true null

Steps to Reproduce

  1. Create a button which launches a read-only harness
  2. Create a grid and source this grid from a read-only data page
  3. Create a button inside the grid and OnClick configure 'Open Local action' to launch flow action
  4. Click the button. The flow action does not launch

Root Cause

The 'Disable Work Processing' option is not checked in the Local Action setting.
During runtime, the Grid copies the row page to a new thread. Since the read-only data page cannot be copied, this results in an exception.


Perform the following local-change:

Select the 'Disable work Processing' option in the Local Action configuration.
