checkBox in Jtable renderining problem

[pothraj]

Hi All,
I am using Jtable with checkboxes as groups and subgroups.
My first Row,My first column is a checkbox followed by the groupName

My secondRow,third column will be the checkbox containg all the subgroup values ..it's some thing like

CkeckBox Group1
Checkbox Sub1 1 2 3 4
Checkbox Sub2 2 3 3 3
CheckBOx Group2
Checkbox Sub3 1 2 3 4
Checkbox Sub4 2 3 3 3


when clicking on CkeckBox Group1 all checkboxes under group1 must be checked.i.e. checkBox sub1 and sub2 must be checked..viceversa for deseleceting the checkBoxGroup1.

similarly for checkBox group2 ..

but when I am trying to do the same when clciking on group2 then also subgroups of group1 are selected..
may be this is becoz of renderining problem..

any help?????
