[7.0] hidden & mandatory fields in analytic form view

Test done on runbot 7-0-13627

When creating a analytic account called in my example 'holidays' in form view with a type 'analytic account' ; tick the checkbox 'timesheet' => if you timesheet on the account, the invoice rate will be empty (which is correct)

Now, on the same analytic account, change the type to 'contract or project', create a template (with a price list and 100% invoicing rate) and Save => if you timesheet on the account, the invoice rate will be 100%.

Finally, on the same analytic account, try to remove invoice rate to blank first, change back the type to 'analytic account' => you cannot save => the field should not be requiered since it is invisible

=> The problem is now, if I want to timesheet on this account the invoicing rate is not blank anymore => consequence : it will create analytic lines to be invoiced (=> I do not want to see this line as to be invoice since it is only holidays)
