Hi, This may be a limitation of Wicket itself.
DateTimePicker is a FormComponentPanel, i.e. it is not attached to HTML form element but most probably to a <div> that has some HTML form elements inside it. I am not 100% sure but AFAIR wicket-ajax.js doesn't traverse the children of the <div>. It just tries to get the 'value' of the form component with wicket:id on it, in this case the <div>, so it will send 'null' as a value. Once this is improved I think we will need to improve the server side as well. As you can see at [1] it updates only the formComponent's model, but not the models of its children in case of FormComponentPanel. I'll be able to run the application later today or tomorrow to confirm this. Please file a ticket for improvement at Wicket JIRA.
