Form to be populated.

Hi,

the norwegian form for refund of of withholding tax cannot be populated with
okular. The Problem seems to be the contained Javascript logic. The user can
enter the Gross amount in NOK of the stock to be refunded. The withholding tax
of 25% should be cacualted by the form, same with the refund claim of 10%.
for some reason, the calculation fo the sum seems to work.
I do not have to mention that it works with the acrobat reader.
another thing i notice is, that popuating the form fields is supper slow for
some reason - when you press a key you can visibly notice the latency until the
key shows up in the form.

The form can be found here:

(see attachment)


STEPS TO REPRODUCE
1. open pdf file
2. goto section 5
3. enter amounts in the column "Gross amount in NOK"


OBSERVED RESULT
The dependent columns remain unchanged with value 0.0 (withholding tax and
refund claim)

EXPECTED RESULT
The dependent columns should be automatically calulated (withholding tax and
refund claim)
