Getting correct value from multiple rows

hi guys

On my screen i have three rows (UserVO) , like this

ID   NAME    GROUP
--   ----    -----
1     Jay     T            
2     Jay     I            
3     Jay     P            


ID and NAME are text boxes and GROUP is a dropdown. So the basic functionality is
if user selects 'I' or 'P' from GROUP drop-down, Name field should become readonly. When user selects
T, the Name field should again become editable text box. so when user selects I or P, Jay becomes readonly and when user selects T, Jay becomes editable.

Basically i am displaying the above rows using java code (I am putting all the individual rows in a List and
iterating throught the list and displaying them ;

for(int row=0 ; row < List.size();row++)
{
UserVO user = (UserVO) List.get(cnt);
// get Group value
String group = form.getGroup();  getting the Group value here
if(groupType = I || groupType = P)
{
Disable the Name field
}

Basically here i want to get the Group value from individual rows and check if it is I or P or T individually for each row and then disable the name field for that row


but the problem is String group = form.getGroup(); will give the group value correctly just for the
first row.   The second and third row dont work because form.getGroup();   doesnt recognize those rows, so i am thinking may be i should pass some index instead of doing  String group = form.getGroup();

for(int row=0 ; row < List.size();row++)
{
...
String group = form.getGroup()[index of 1st / 2nd /3rd row]}
but i am not sure how to impliment this , any ideas will be greatly appreciated

thanks
J
