Did you trace it , are you getting the errors in the tracer ? If you are getting the errors in the tracer that means your validation is working but the messages are not coming in the front end . Use a normal validate rule from the flow action , that will work for you .
The validation rule is working fine. But the modal dialog is closing and since the error is present on the temporary page a blank row is getting updated in the grid context. Since no error message is present in pyWorkPage context the flow proceeds to the next screen upon submission.
We need to stop the user from returning to the grid by displaying the error in the modal dialog itself. Any ideas as to how to prevent the modal dialog from closing when error is present on the page context the modal dialog is streamed on?
We are using both validation rule and some complex validation in the activity. I have selected both the check boxes but still the same issue persists.
The validation are working fine as the error is being set on the page, but the modal dialog gets closed and the user is able to proceed to the next screen as the error is present on the temporary page.
