Hi,
I tried to move if-then logic (see below) to the onWebEvent() of the 'recalculate'.
It did not make any difference. I also moved this whole code to another page
onBeforeDisplayEvent()
in which I got the 'cart' page and then obtained the repeated and then
'quantity'
value. It still says 'It is NOT a vector' and that single value is always a
null
value. Suspecting that href may not be submitting the form values, I
converted href
to a button. It still did not work. I am setting the initial values for the
repeated
'quantity' text box. I do not know if this makes any difference (I created a
test
cart page and a refreshed cart page. I did not set initial values for the
text box.
I did not add any other repeated elements. It now says 'It is a vector'. If
set initial
value or if I add any other repeated elements it says 'It is NOT a vector').
Please suggest any thing! I will try it. I am getting desperate to solve this before
next week.
Thanks,
-Bhaskara Reddy.
