UpdatePresentation mutation systematically reset paperNumber to 0

UpdatePresentation mutation systematically reset paperNumber to 0

Hi,

For once it looks like the title says it all : When the UpdatePresentation mutation in ran, paperNumber is systematically reset to 0.

A few weeks (month) ago I've already open a ticket about paperNumber (in creation mutation this time).

I think the value for paperNumber in mutations should be either the value passed as parameter (for both update and create mutation) or if no parameter is passed…

 - automatic increment from the last created paper in case of creattion
 - unchange in case of an update

Thank you in advanced,
Regards,

Cedric
