Dear all,

We have a table populated by a Data Page, where each row includes a local action that triggers a flow action, allowing us to perform specific actions for that row.

The flow action runs in the Page context, and we populate this page using the Pre-Processing Data Transform. Additionally, we have a validation rule and a post-activity that executes the actual logic upon clicking the submit button.

Issue

The validation rule works correctly by setting messages on the temporary page populated earlier. However, after addressing the validation errors and resubmitting the form:

• The validation messages disappear from the UI.

• However, the same messages persist on the Data Page (as confirmed via Clipboard and Tracer).

• These messages are preventing the successful submission of the flow action.

I’m unsure why the messages are being written to the Data Page in the first place, but even if they are, I should be able to remove them using OOTB functions like pxClearMessages—yet this has not worked.

What I Tried

1. Moved the validation logic to the post-activity instead of the validation rule on the Flow Action

   • The validations executed correctly.

   • However, since the Primary Page (which somehow points to the Data Page) had no messages, the activity completed without issues.

2. Manually adding a message using @Default.pxAddMessageToPage

   • This correctly stops the activity execution.

   • But then, I am stuck in a loop where the message persists on the Data Page, and I am unable to remove it.

3. Tried calling an activity to remove messages from the Data Page

   • But I haven't been able to get it to work so far.

Question

Why am I able to add messages to the Data Page but unable to remove them? Any insights or suggestions on how to resolve this would be greatly appreciated.
