Hi,

I have a table

UzivId - PK
ProjectId - PK
Note 

This is my code

            var projectUziv = new TfProjectsXfUzivEntity
            {
                UzivId = 1,
                Note = "ss"
            };

            var filter = new RelationPredicateBucket();
            filter.PredicateExpression.Add(TfProjectsXfUzivFields.ProjectId == 1);
            filter.PredicateExpression.Add(TfProjectsXfUzivFields.UzivId == 0);

            _adapter.UpdateEntitiesDirectly(projectUziv, filter);

and the generated code.

UPDATE "SMTAPP"."TF_PROJECTS_XF_UZIV" SET "NOTE"=:p1 WHERE ( ( ( "SMTAPP"."TF_PROJECTS_XF_UZIV"."PROJECT_ID" = :p2 AND "SMTAPP"."TF_PROJECTS_XF_UZIV"."UZIV_ID" = :p3)))

The point is the field UzivId doesn't get updated in the query.

I'm using the 3.1.0.0 and Oracle.

PK's can be updated, but only in single entity saves, so you update a PK field in an entity and save it again. Using direct updates won't update PK's.
