Hi evrybody!!
Its ok now i know what was the problem.
In fact as i say, its a Bug But odoo community does not see it as a bug because its their phylosophia.
Here is the explanation:
Hello,
Sorry but this is not a bug.
We want the statusbar to act as button and not as a field. A simple reason is the ability to click on it in readonly mode (should not be possible to click as we need a discard button). For objects such as task or tickets, we do not want to do "edit-change status-save", we want to do the action in one click (as you drop from one stage to the other in kanban view).
The patch is not wrong itself (even if it does not seem to take care of edit mode, it should) but I will reject it as we do not want to merge this in standard version.
Regards
