hi josh,
thx for your reply , i have solved my problem with 2 variables .
my situation is like this
Grid at top of page (list) , and bottom is a form (detail)
at grid, I have
t:row id="abc"
and at form , I use value="abc" also
then I initial the value at pageLoaded .
since t:row also use the same variable , that why the value is
overwritten during the rendering ..
