Hello,

We have a 4.4.0-1240 version of the Java SDK , and tested the sample code of the Pub/Sub.

In the samplepubsubpublisherserver project, has the below code.

variableDataSetConf.addPublishedVariables(UaNodeId.fromLocal(myNodeManager.myLevel.getNodeId(), server.getNamespaceTable()));
variableDataSetConf .addPublishedVariables(PubSubPublishedVariableConf.builder().setAttributeId(Attributes.DisplayName) .setPublishedVariable(UaNodeId.fromLocal(myNodeManager.myLevel.getNodeId(), server.getNamespaceTable())).build());

and got the output message from the samplepubsubsubscriberserver project

Received DataSetMessage from DataSetWriter 432
MyLevel: PubSubDataValue [ encodingType=DataValue serverTimestamp=-1000000000-01-01T00:00:00Z sourceTimestamp=-1000000000-01-01T00:00:00Z statusCode=Bad_WaitingForInitialData (0x80320000) “Waiting for the server to obtain values from the underlying data source.” value=(null)]

First, the value of MyLevelDisplayName is the right value (MyLevel string), but after it’s values are wrong.

Please help to figure out the problem, thanks.
