FULL PRODUCT VERSION :
1.6.0-b105

ADDITIONAL OS VERSION INFORMATION :
Windows XP Spanish

A DESCRIPTION OF THE PROBLEM :
I ran the following code sample that uses one model and two different Jtables and TableRowSorter for each.

Am I doing something wrong or there is a bug somewhere in the Java Classpath.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
The problem I see is that if I sort the first JTable by Price and then change "Time Warner" Price to 117,66 in the second JTable the first JTable changes "TIme Warner" Price to 26,02 wronglingly and does not sort the table as expected.



REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
I do not have this problem if I use instead the old TableSorter.java from:
