Getting null pointer exception at jDateChooser when application starts

Question

I am using jDateChooser plugin on netbeans. When application starts it throws nullpointerException but when I choose date it works fine. The one and only one problem is it throws exception at runtime. Following is my code where I am getting exception:

String startDate=new SimpleDateFormat("yyyy-MM-dd").format(filterByStartDateChooser.getDate())

Note: I am using netbeans gui to design form.

Please solve my issue.Thanks

This might happen during initialisation. some function or actionlistener might want to read out the jdatechooser while it has no date set. to avoid this, simply add

jDateChooser.setCalendar(Calendar.getInstance());

after creatign your jDatechooser.
