Ok, I'll write a mail to the support team.
I've tried now with the following function and I've recived the mail. So the problem is the valdation.
function ff_validate_submit(element, action)
{
ff_submitForm();
}
This is the original function
function ff_validate_submit(element, action)
{
if(typeof bfUseErrorAlerts != 'undefined'){
$jq(".bfErrorMessage").html('');
$jq(".bfErrorMessage").css("display","none");
}
error = ff_validation(0);
if (error != '') {
if(typeof bfUseErrorAlerts == 'undefined'){
alert(error);
} else {
bfShowErrors(error);
}
ff_validationFocus();
} else
ff_submitForm();
} // ff_validate_submit
Greetings
Michael
