I am using struts 2.0.14 and I'm having an issue where I have a Collection of Collections of datetimepicker values. I am retrieving the time values from a database and they are all being displayed properly. I can make changes to the time and it is working. The problem that I have is when I submit the page back the Collections are empty within the Java code when the update() method is called.
