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


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 | ../{{}} I set a text input with value ==> 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 ?
