Hi

There is a difference between SDK 4.10.6-24 and 5.1.0-116 regarding the namespace of instances.
SDK 4.10.6-24: MyEventType ev = createEvent(MyEventType.class); the event was in the namespace of MyNodeManager; ev.getNodeManager() returned MyNodeManager
SDK 5.1.0-116: MyEventType ev = createEvent(MyEventType.class); the event is in the server namespace; ev.getNodeManager() returns NodeMangerRoot

Is this an intended change?
In the change history of version 5.1.0-116 I cannot find any reference to this.

Best regards,
Manfred

Hello,

From 5.x.x onwards, the NodeManager of a created Node is selected based on its NodeId. For one-shot Events, the NodeId.NULL is used, which is ns=0;i=0 to be exact, for which the RootNodeManager is selected.

Hi Matti

Thanks for your swift reply.
The explanation makes sense to me.

The sample server that comes with the SDK is therefore no longer able to set MyVariable or MyProperty because the methods MyEventType.setMyVariable(…) and also MyEventType.setMyProperty(…) do not find the components MyVariable resp. MyProperty via browse name. This is because MyEventType is created in MyNodeManager.NAMESPACE. You might want to correct this problem with the next release.

Best regards,
Manfred

Hello,

I can confirm that this bug exists in the current release of the SDK. Thank you for reporting it to us. It will be fixed in the next release of the SDK.

You can fix this by modifying the getMyPropertyNode and getMyVariableNode methods of MyEventType class. They’re relying on the getNodeManager().getNamespaceIndex() to get the NamespaceIndex for the QualifiedName. Calling that returns 0, which is incorrect, so you can replace the getNodeManager().getNamespaceIndex() calls with a constant value of 2, which is the NamespaceIndex of MyNodeManager.
