update product on ddt

Ok matteo, it seems that I'm the only user with this problem, but we have installed it on xampp with mysql and php, and the problem still remain.

1-Create quote ---OK it works.

now i need to change something in the quotation so:

first way (go directly on modification form):
1-enter on it using modify icon
2-no product details and amount are displayed.
3-no pdf is created with data

second way:
1-enter on it using the "objet" columns we have selected the only quotation we have made.
2-no product description is displayed on form, only TOTAL amount fields.
3-click on the edit botton( top right ) and we arrive on quote modification form.
4-the same described in the "first way"

This is what happen in our test made on two sistems with different S.O.

thks

None have the same problem?
Well after some test's day we have found a solution, but please VTECRM teams test it and let me know!!
In quote form the field TAX MODE is setting to "Individual" and the quote seems to saved perfectly but no product descrpt was attached.
Changing the tax mode into "group" is working yes, but first you have to save the quote (the tax field the first time is 0 and no correction is possible) as is with product selected, then you must edit and inser manually the tax value (22%) due now the field works good.

Please check if you have the same problem.
