Refresh issue in apps (Procurement request) - Prod env (Tomcat+MySql)

Hello.

I installed the Procurement requests example on a production platform (Bonita 7.1.2, Tomcat, MySql).

When create a new request, the page returns to the listing, but the new request doesn’t appear until I actualize the browser’s page.

This issue also appear when I complete quotation, and when I select the supplier : the “status” of the request is not update…

This issue doesn’t appear in developpement environment.

What can cause this issue ?
