I have a custom schema and collection with a uid to ensure a unique id:
{
"autogen": "${rally}-${uid}"
}
When I create a new object, the uid appears as soon as I click + New Object. I'm sure I remember the uid only appearing after I entered a title?
In this example, Rally is the field that generates the id and I didn't remember the uid being added until after entering something in the field.
I might just be misremembering this?
