Name: gm110360 Date: 07/13/2004
FULL PRODUCT VERSION :
All Versions, even I test it in JDK 1.5 beta 2
ADDITIONAL OS VERSION INFORMATION :
All windows platforms.
A DESCRIPTION OF THE PROBLEM :
This can be easily reproduced using the samples from
http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#sorting
Running the TableSorterDemo.java sample with just one change which is setting the orientation to "ComponentOrientation.RIGHT_TO_LEFT" breaks the sorting.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
in your table example which deployed with JDK,
the bug when change the Component Orientation to Right to left ,
and Resizing the table header then , the sorting action is throws in wrong way.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Correct sorting
ACTUAL -
bug in Table header , I suggest that table header should be like cells
in Editor , this is the correct way only.
Am realy ask sun , why there is no Editor for Table Header ,
this is why the hug bug released.
JTable header render not enough.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
no Error message , but Error in GUI .
REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
I like Java , and work with it when JDK 1.2.0 released. but I know simply JDK 1.0 - JDK 1.7
am always download each new version , but realy the best work is JDK 1.5 , but still I want Java to be more improved. JDK 1.5 is just joke for enhancement GUI speed , but you have to know that Java in proccessing is still to much slow.
I developed Compression utility that can compress zip format from 2% to 10% but the problem it tack too much time, ecpicaily in java processing.
