I have a text dynamic field required to contain only numbers. I'm thinking of using an ACL with a RegEx to enforce this rule but I can't get the ACL to trigger.

Is what I want possible? Maybe I'm on the wrong track and ACLs are not applicable to *text* dynamic fields?

    $Self->{TicketAcl}->{'10-ACL-Test'} = {
        Properties => {
            Frontend => {
                Action => ['[RegExp]^Agent.*']
            },
        },

        Possible => {
            Ticket => {
                DynamicField_tbx1 => ['[RegExp]^[0-9]*']
            },
        },
    };

Thanks,
