The domain model looks as follows: Where Offreren.Offerte is a specialization of Register. [UPDATE] Setting the ConnectionBus_MappIng to Trace shows: Mapped query: SELECT offreren$offerte.id, dj1dcm$register.registerid, dj1dcm$register.omschrijving FROM offreren$offerte INNER JOIN dcm$register AS dj1dcm$register ON dj1dcm$register.id = offreren$offerte.id WHERE offreren$offerte.id = 23643898043695307 Dependent queries: { SELECT DISTINCT dcm$registercase.dcm$registerid, dcm$registercase.dcm$caseid FROM dcm$registercase WHERE dcm$register_case.dcm$registerid = } How does this work? Where does the Dependent query come from? [ORIGINAL MESSAGE] I have a microflow which I call through a Java Action (CommunityCommons.ExecuteMicroflowAsUser_2). In this MF a Register entity is retrieved over association from a TaakInstantie. This retrieve results in a java.lang.NullPointerException. When debugging this microflow I see that I have a TaakInstantie. I set the ConnectionBus_Retrieve to Trace and got the following results: RequestAnalyzer: incoming request IdentifierGetRequest: Object types: [Offreren.Offerte] RequestAnalyzer: incoming request info:IdentifierGetRequest { [MendixIdentifier:: id=23643898043695205 objectType=Offreren.Offerte entityID=84] } SQL: SELECT "offreren$offerte"."id", "dj1dcm$register"."registerid", "dj1dcm$register"."omschrijving" FROM "offreren$offerte" INNER JOIN "dcm$register" "dj1dcm$register" ON "dj1dcm$register"."id" = "offreren$offerte"."id" WHERE "offreren$offerte"."id" = 23643898043695205 Data table Offreren.Offerte (0 row(s)) Column names: 1 offreren$offerte.ID PRIMARY 2 RegisterID 3 Omschrijving Even if there are no Offertes (a specialization of Register) I wouldn't expect a Java-exception. What could cause this behaviour?
