In xsl, i create two list boxes 'cboDim1' for dim1 values
and two list boxes 'cboDim2' for dim2 values

in fact, i m using a recursive template to create two set of listboxes cboDim1 and cboDim2...


So, when i select a value from 'cboDim1', 'cboDim2' should get populated...

can somebody please tell me how do i get about this? And, I cannot change this xml as it is generated from Java code...

Thanks in advance,
Tanuja
