Hi @Jonathan

In our project we have created custom error message by creating message rule and reffering the same in the activity, which is mentioned in the Actions tab of the control.

For Instance, we are validating  selection of checkbox which in grid repeat layout, on Click of Submit button without selection of checkbox we are displaying error message, to display this error message we have created one dynamic layout (for this Dynamic layout in General tab >>Layoutformat should be Other >> Mimic a sentence and  Container Format should be Other >> Errors. PFA images)

in which we are displaying the message rule with name "CheckSelection". 

In Activity using Property-Set-messages method we can call message rule. Hope this will help you.

Thankyou

Thank you for your answer, but this is not what I'm looking for. - I want to customize the screen as attached in my post, not validation/form errors.

Hi,

I think 'ActivityStatusError' is the rule you are looking for to customize the error screen. You can confirm that using developer tools(F12), you can get the section name from here.

As i see you tried modifying the rule already, but looks like it is not getting picked up when accessed through SSO. If possible try tracing the session and see which ruleset section stream is getting picked.

Thanks.
