Custom document type with child relation

[olylak]

Hi everyone,

I have a following requirement:

Custom document type myocument (inherited from cm:content) should always have myataFile attached to it.

As a result we should have:

1. When we create myocument it should always have one mandatory myataFile.

2. When we delete myocument - myataFile is deleted as well.

3. myataFile should not be visible for the users (in share ui). 

Any suggestions or samples will be appreciated.

Basically you have to define a custom content model in Repository and to customise forms and fields in Share.
