I did a demo followed the manual-5.8.3 “Editing Composite Entities”,and i found if i create the
Master Entity extends BaseStringIdEntity,then i could create and edit the “Master-Detail” entities well,
but when delete ,i got the Exception “The state field path ‘e.username.id’ cannot be resolved to a valid type.”
(e is the detail entity,username is the master entity’s id).
If let Master entity extends StandardEntity,it work well.
I use Studio 2.0.6 ,platform 6.0.9.
Wish you could help.
