Problem binding dropdown with BDM

Hello,

I'm using Bonita 7.3.

I have created the following BDM:

• Notificacion (BDM Object)

  • codigo (String)
  • descripcion (String)
  • obligatoriedad (BDM Object)

• Obligatoriedad (BDM Object)

  • codigo (String)
  • descripcion (String)

At the beginning of the process, I initialize a process var type "Notificacion" from BDM with an operation (with "findbypersistenceid").

In a second task, I have a form which must retrieve the "Obligatoriedad" field and save it at BDM. For it, I have two form vars:

• "notificacion" that contain the business object ( ../{{context.notificacion_ref.link}} ).

• "tiposObligatoriedad" that contain the available types at BDM to bind with a dropdown ( ../API/bdm/businessData/com.company.model.Obligatoriedad?q=find&p=0&c=10 )

  In the form I have used a DropDown with the following configuration:

• Available values: tiposObligatoriedad

• Key shown: descripcion
• Return key: empty to return the entire object
• Value: notificacion.obligatoriedad

The value of "formOutput" var is

return {
'notificacionInput': $data.notificacion
};

When I run this process, and select a value from the dropdown, the submit is OK, but when I check the database, I find following error:

Table "Notificacion" (BDM Notificacion)

• PERSISTENCEID = 1
• CODIGO = N5
• DESCRIPCION = "BLABLABLA"
• PERSISTENCEVERSION = 3
• OBLIGATORIEDAD_PID = 5

Table "Obligatoriedad" (BDM Obligatoriedad)

Three records with master data

RECORD 1
- PERSISTENCEID = 1
- CODIGO = OBL
- DESCRIPCION = OBLIGATORIA
- PERSISTENCEVERSION = 0

RECORD 2
- PERSISTENCEID = 2
- CODIGO = VOL
- DESCRIPCION = VOLUNTARIA
- PERSISTENCEVERSION = 0

RECORD 3
- PERSISTENCEID = 3
- CODIGO = NA
- DESCRIPCION = NO APLICA
- PERSISTENCEVERSION = 0

And a fourth record with the selected object at dropdown

RECORD 4

• PERSISTENCEID = 5
• CODIGO = NA
• DESCRIPCION = NO APLICA
• PERSISTENCEVERSION = 3

The problem is, that I need that if I select for example the value "NO APLICA" from the dropdown, BDM don't create a new record. BDM must set the field "OBLIGATORIEDAD_PID" in "NOTIFICACION" table to the value 3, it is the PERSISTENCEID for the value selected (NO APLICA)

Some help please?
