Q&A
1

Hello,

i use Bonitasoft community edition 2022.2

i have Object called "Rooms" have attributes:

  • roomName
  • roomNumber

I have Object called "Home" that have attributes:

  • Name
  • Rooms (multiple)

In instantiation, when i added the contract input of "Home" , i can't select  "roomName" and "roomNumber" , i just get "persistenceId_string"

but when i use task Inputs, i can select this attributes

How can i get all attributes of "room" object in my initiation form not just "persistenceId_string" to submit my form correctly ?

Hi,

When the relation in Business Object is an aggregation type, the lifecycle o those objects are loosly coupled. It means that a Room instance must already exist before adding it to the rooms of your Home. If you need a more tightly coupled reference, you can use a composition relation, in this case, you’ll be able to create your House rooms’ in the same transaction. In addition, if you remove a House instance, it will delete the rooms instances in cascade.
