Getting null pointer exception at jDateChooser when application starts

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

Solution

  • 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.
