the messages are not displayed in Production mode. The tag is intended
for development use, not for error reporting in deployed applications.

Sample
In this first sample, because the <netui:bindingUpdateErrors/> tag is unqualified,
messages will be displayed if any data binding errors occurred when a form was
posted. The messages are displayed on the page and in the Server console.
<netui:bindingUpdateErrors />
In this next sample, only binding errors for the expression {actionForm.firstName}
will be displayed.
<netui:bindingUpdateErrors expression="{actionForm.firstName}"/>
