Hi Marty, now this is just me throwing this out here before I've had my
breakfast, but... if the field Project.ID is on the project object type
already, couldn't you reverse the filter?
Project.ID=FIELD:IDProject.ID_MOD=in You can't use just ID because as
you mentioned, the system will override that if placed in a layout
template on on the left nav of an object. But it won't touch your custom
field. I haven't tested this out, but thought I'd throw that out there.
