This occurred after the conversion from 4.2.2 to 4.4.2. com.mendix.core.CoreException: com.mendix.core.CoreRuntimeException: replication.ValueParser$ParseException: com.mendix.core.CoreException: com.mendix.core.CoreRuntimeException: java.lang.NullPointerException at com.mendix.core.Core.execute(SourceFile:232) Caused by: com.mendix.core.CoreRuntimeException: replication.ValueParser$ParseException: com.mendix.core.CoreException: com.mendix.core.CoreRuntimeException: java.lang.NullPointerException at hC.b(SourceFile:214) Caused by: replication.ValueParser$ParseException: com.mendix.core.CoreException: com.mendix.core.CoreRuntimeException: java.lang.NullPointerException at databasereplication.implementation.DBValueParser.getValue(DBValueParser.java:128) Caused by: com.mendix.core.CoreException: com.mendix.core.CoreRuntimeException: java.lang.NullPointerException at com.mendix.core.Core.execute(SourceFile:308) Caused by: com.mendix.core.CoreRuntimeException: java.lang.NullPointerException at hC.b(SourceFile:214) Caused by: java.lang.NullPointerException at ms.m(SourceFile:120) at ms.executeAction(SourceFile:88) at com.mendix.systemwideinterfaces.core.UserAction.execute(SourceFile:57) at com.mendix.core.actionmanagement.CoreAction.call(SourceFile:457) at hC.b(SourceFile:203) at com.mendix.core.Core.execute(SourceFile:304) at com.mendix.core.Core.execute(SourceFile:280) at replication.implementation.MFValueParser.parseValue(MFValueParser.java:111) at databasereplication.implementation.DBValueParser.getValue(DBValueParser.java:116) at databasereplication.implementation.DataManager.startSynchronizing(DataManager.java:165) at databasereplication.actions.ImportByMapping.importFromDatabase(ImportByMapping.java:114) at databasereplication.actions.ImportByMapping.executeAction(ImportByMapping.java:96) at databasereplication.actions.ImportByMapping.executeAction(ImportByMapping.java:72) at com.mendix.systemwideinterfaces.core.UserAction.execute(SourceFile:57) at com.mendix.core.actionmanagement.CoreAction.call(SourceFile:457) at hC.b(SourceFile:203) at com.mendix.core.Core.execute(SourceFile:226) at ln.a(SourceFile:69) at mt.a(SourceFile:72) at ms.a(SourceFile:151) at ms.executeAction(SourceFile:98) at com.mendix.systemwideinterfaces.core.UserAction.execute(SourceFile:57) at hD.execute(SourceFile:27) at com.mendix.core.actionmanagement.CoreAction.call(SourceFile:457) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662)
