It should just work if you've set the right rules.
Check out the example project on the page below. I created new Persons with avatars and I don't remember doing anything special, certainly not in the model.
What rules are you using for the attachment property?
For that matter, what properties are you using to configure the ERAttachment?

Hi Peter,
Welcome to the list. I am surprised the Davids, the gentlemen, and Chuck have not responded yet.
The only way I am aware of is in the awake from insertion, namely to have one always inserted when the EO is created. But, that seems like swap fly with shot gun approach.

I have a table called person, and the ERAttachment is an avatar to that person. My migrations setup initial values for a person, and I can add an avatar (ERAttachment) to an existing person.
When I try to create a new person (within ERModernLook) and try to add the avatar I get a NullPropertyException thrown. I think what happens (correct me if I'm wrong) is that the there is no primary key assigned to my person object and values for attributes in person object are not saved in the database and when ERAttachment tries to make a relationship pointing back to the person object it throws the exception "type: NullPropertyException; additionalExceptions: ()>".
How do I fix this? Thank you for your help.
Very respectfully,
Peter
