Struts 2 & DateTimePicker: Works fine but throws Exception.

Hello!
So, I have a DateTimePicker, which is used to set the date of a booking.
It works just fine, my actionclass can collect the date and call an insert on my database with the value.
But everytime I press my Save button I get this exception:

ognl.OgnlException: target is null for setProperty(null, "date", [Ljava.lang.String;@ae48dc)

It doesn't interfere with anything, the date is still inserted into the db, but I can't help but wonder what it's all about.
Any ideas?

Thanks in advance,
Alia
