Variables in MyBigNodeManager based on strange DataItemType definition

Hello,
the variables contained in MyBigNodeManager have a strange TypeDefinition “ns=6:s=DataItemType”.
What is the purpose of these nodes? Since they are not based on the DataItemType “ns=0;i=2365” which is definied in the Data Access Specification, they will probably not be encountered as a valid type for standard data access applications…

best regards
Hartmut

Yes, that is a bit unfortunately named similar to the standard type. This was just intended to be a sample custom VariableType, in case you want to provide that from the custom node manager as well.

In practice, though, it is much easier to implement all types with normal UaNode based objects in a NodeManagerUaNode type of NodeManager. This will simplify the custom NodeManager implementation as well.

And usually, it is best to stick to standard variable types as much as possible as well.

And yes, since your question was related to SimulationServer the follow up to this is that the example originates from the Java SDK samples – and makes even less sense in the SimulationServer.

I guess we should clean this up from the future versions of the product.

It certainly makes sense in the SimulationServer to have some kind of a big block of items that can be used for testing in Clients (MyBigNodeManager). But these variables should just be based on standard DataItemtype. This would be nice…
Thanks!
