invoice advance and taxes

Hi everybody,

I would like to know how do you manage taxes on invoice advance?

By the way, I have a sale order of 2.000 € w/o taxes => 2.392 € all taxes included (french VAT @ 19.6%) If I create an invoice advance of 10%, it will create an invoice of 239,20 € all taxes included but no taxes are displayed on the invoice.

I've tried a lot of things like overriding the wizard (sale_make_invoice_advance) in order to check what's going on, step by step. It seems that the function "product_id_change" on "invoice line" object doesn't return any taxes...

I could explain further all the different things I've tried, but for the moment, I'll make this first post as simple as possible and just ask how we can manage those things "nativelly".

Hoping someone could help me!

Thanks in advance,
