How to read order_line view fields dynamically within the on_change method of pricelist

By

Hi,

I've got a simple question which I didn't find in a couple of threads.

I'm modifying the on_change method of the pricelist field belonging to the purchase module. The pricelist field should always actualize the prices of all order_line product entries when the pricelist itself has been changed. For this purpose, it is necessary to read all "price_unit" fields belonging to the one2many field "order_line". The fields are inside the purchase form view (purchase_order_form). The problem is that I can't read the fields belonging to the order_line directly (maybe because they reside in purchase.order.line and not in purchase.order)
What I tried:
I added order line as a parameter for the onchange_pricelist method (both in the view and python coden) and debugged the variable order_line: It is not giving any information of the order lines!
Maybe it is not possible to read the order_lines dynamically without storing them into the database? Maybe only dynamically updating works?
>>Does somebody have a solution how I can read the price_unit dynamically?<<

I copied a fragment of the purchase_order_form view, so you can look up the view structure at once.

<record id="purchase_order_form" model="ir.ui.view">
