It will be hard to provide an example of the problem I have because of trying to extract it from my companies pages and still maintain the same conditions so I want to start by just asking to see if anyone has encountered a similar problem if I explain it.

Without putting the whole markup this below shows that I have a Window with a CardLayout giving me several forms which I can choose to show or hide dependant on the caller of the form.

What is happening is that when I choose a date using the drop down calendar of the DateField the date in the textfield is wrong by one month. For example if I choose 05/03/2009 on the calendar. It puts 05/04/2009 in the TextField.

Does anyone have any suggestions?
