[tryton] updating a calculated field while filling a form

[Cato Nano]

My "total" field on the Bolletta entity is calculated.

It's the sum of a value from the lines PLUS some bits

In the GUI (and in SAO) the total gets updated while filling a line only with the value from said line

The further bits get acconted for only after saving the Bolletta.

I suppose that the javascript layer updates the total field generically summing on the client side

The complete calculation gets done on the server, after saving

Is there a way I could make the GUI showing the properly updated values while editing a line ?

Thanks in advance

the values that do not get acconted for in the sum are calculated starting from line no. 8, as you can see here

I think the issue is: how do I get a calculated field updated with a temporary value BEFORE the record is saved ?

Using One2Many in on_change method can be a little bit tricky because we
have not yet a way to express what values will be sent. So the client
for now send all the values it knows and if it is a saved record the
server should read the missing value.
But in your code, you are calling other on_change methods and probably
they are missing some values.
A common tip to fix that is to add the missing field as tree_invisible
in the tree view to ensure to have them.

Thank you
