DynamicLogic for Address field

[simond]

Hello,

I am trying to conditionally set the required attribute on the "billingAddressPostalCode" field of the "Account" entity.
Using the entity manager I can set an enum as condition for other fields (for example "website") and it works fine.

For either of the "billingAddress" fields however, the condition does nothing.
Directly using a clientDefs/Account.json file (as seen below) does not yield any changes either.

 {
    "dynamicLogic": {
      "fields": {
        "billingAddressPostalCode": {
          "required": {
            "conditionGroup": [
              {
                "type": "equals",
                "attribute": "kundenart",
                "value": "Privatperson"
              }
            ]
          }
        }
      }
    }
  }

Is this caused by some relationship to the "billingAddress" address field?

Best wishes and thanks in advance
Simon
