[Rapid application] Error message not displayed correctly when changing configuration

Hello experts,

I'm new on CRM WebClient UI developpement. I've created a rapid application based on a database table.

My requirement is that depending on a DDL value, the screen layout change (fields are hidden and others are displayed and mandatory).

I created 2 configurations (I changed the DO_CONFIG_DETERMINATION method) with 2 component usages and the call of configuration is correct and the 2 layouts are displayed depending on the DDL field value.

The problem is that when switching from the second configuration (layout 2) to first configuration (layout 1), the error message asking to fill the "Field 4" is still displayed though the field is hidden.

Do you have any idea why the message is still displayed or how could I hide it ?

Thank you in advance for your ideas.

Regards,

Imane
