Description MackSix 2011-10-25 05:53:48 UTC 
Created attachment 112386 [details]
Project that exhibits the error.

1) Create new Project
2) Create new JFrame Form. (i.e. MyJFrame.java)
3) Add all 7 JCalender Beans from http://www.toedter.com/en/jcalendar/
   JLocaleChooser
   JDayChooser
   JCalendar
   JDateChooser
   JMonthChooser
   JSpinField
   JYearChooser
4) Check doubleBuffered Properties for all 7 JCalendar components.
5) Copy JFrame Form using Refactoring.
6) Notice that 6 out of 7 setDoubleBuffered() Methods are missing in copy.

See attached project with JCalender Beans already included.

Comment 2 Jan Stola 2011-10-25 12:51:58 UTC 
In fact, it is not necessary to copy the form. It is sufficient to close it, reopen it and do some unrelated change that forces regeneration of the source code.

The resulting code (with only one setDoubleBuffered() method) is correct because the default value of doubleBuffered property of all the mentioned components (except JLocaleChooser) is true. Hence, only JLocaleChooser requires this statement to be generated.

On the other hand, the initial state is incorrect. When the other (i.e., not JLocalChooser) components are added then Properties window incorrectly shows that the default value of their doubleBuffered property is false.

This is caused by the lazy initialization of default values of the properties and by the fact that we set doubleBuffered property to false during painting of the component being added. We have to restore the original value of this property when the component is added.

Fixed.
