Hello,

When trying to enter spent time on a project task (Project>Tasks>Select a task>Edit>Add an item) I get the following error:

Traceback (most recent call last):

TypeError: on_change_user_id() takes at least 6 arguments (5 given) 

From my investigations in the forum,  similar issues happen  dur to ne'w vs old API issue... But this does not help ma to solve my current problem.

I use the nightly built from last night (May18)

Any help is appreciated
