After switching from ice.singleSubmit() to ice.ser in calendar component, the following problems were observed:

- JS null pointer exception, see attached screenshot. This happens in code trying to do a diff. of component properties on the client side between renderings. Just check singleSubmit checkbox and select a date or time. It should trigger single submit and the error.
- In popup with text input, the display date formatting in the input field was done with a single submit after clicking OK in the calendar. This doesn't work anymore. Nothing happens until a full submit (by clicking on the the checkboxes.)
- The renderAsPopup and renderInputField checkboxes are submitted with ice.submit(). They don't seem to work anymore in IE. Sometimes nothing happends to change the calendar display mode; sometimes the display mode just gets out of sync with the checkboxes. It still works OK in FF.
