Responsabile not needed for status "assigned"

Hello,

when item is set in status "assigned", responsable is not required.
We have to pass to first state "in progress" to set it.

Is it expected ? It seems that status "assigned" needs to set Responsable who's item is assigned.

I use workflow with differents status and assigned is good for setting responsable in KANBAN before responsable start working (status "in progress").

Here are the states i use :
 

Here is the KANBAN :
 

Passing from "accepté" to "assigné" doesn't ask for responsable, it ask only when passing from "assigné" to "en cours".

Expect to be clear.

Regards,

Hello,

thanks for reply but this lead only to error message "invalid control : field responsable in mandatory"....
Is it possible to get a popup to set the responsable (from list of ressource on task) like for result for example ?

So we can use KANBAN to the whole cycle, whitout the need to open activity to set responsable only when it goes to "assigned".

Regards,
