Failing Tests with CustomerFindController

[nPraml]

Hello @rob-bygrave,

we discovered an issue with BeanFindController and findSingleAttribute queries.
If there is a BeanFindController, every property is selected in DefaultServer.BuildQueryRequest. The produced queries and the results are wrong:

TestQuerySingleAttribute.distinctWithFetch:329
Expecting actual:
  "select distinct t0.status, t0.name, t0.smallnote, t0.anniversary, t0.cretime, t0.updtime, t0.version, t0.shipping_address_id, t1.city from o_customer t0 left join o_address t1 on t1.id = t0.billing_address_id"
to contain:
  "select distinct t1.city from o_customer t0 left join o_address t1 on t1.id = t0.billing_address_id"

TestQuerySingleAttribute.findSingleWithFetch:402
Expecting ArrayList:
  [NEW, NEW, ACTIVE, ACTIVE, NEW, NEW, NEW, NEW, NEW, NEW]
to contain:
  ["Auckland"]
but could not find the following element(s):
  ["Auckland"]

Can you tell me why will all properties from t0 be selected when there is a BeanFindController present?
FYI: we use a BeanFindController with postProcess/postProcessMany and the other methods return the default (false or null) values.

Kind regards,
Noemi
