How to access attributes of a business object defined as an attribute of an other business object with an aggregation relationship in UI designer ?

Q&A

Hello,

I defined a Business object like this :
BDO1 :
name : type string
emplacement : type BDO2 with aggregation relationship

BDO2 :
emp_name : type string
…

I try to access emp_name of BDO2 in a form so
I defined a UI variable to access BDO1 instance like femp | …/{{context.BDO1_ref.link}}
I set a text input with value femp.name ==> OK it works
I set a text input with value femp.emplacement.emp_name ==> KO

Is there a way to access emp_name from UI designer ? Is this a bug ? a limitation ?

Hi,

what is the aggregation type? If it’s lazy then the API will not return the object but a link. Change it to eager (always load related objects option in the studio) if you want to access the nested object directly.

It was my first error, the second one was about the contract, as i retrieve an object from an other one, I had to define the object retrieved as a complex one in the contract
