Hi,

I am having problems to read the value of specific node, this is from Server side.

I am sending “myNodeManager” like parameter to other class when I am going to make the call, this is the code:

IoManagerUaNode ioManagerUaNode = new IoManagerUaNode(myNodeManager);
NodeId nodeIdName = new NodeId(2,”Name”); //This is the node I am going to read the value, and it has value!!
try {
DataValue data = ioManagerUaNode.readAttribute(nodeIdName, Attributes.Value, null, null);
String name = data.getValue().toString();
System.out.println(name);
} catch (StatusException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

But, I am getting this error:
ServiceFault: Bad_InternalError (0x80020000) “An internal error occurred as a result of a programming or configuration error.”
Diagnostic Info: java.lang.NullPointerException
at com.prosysopc.ua.server.IoManagerUaNode.readValue(SourceFile:119)
at com.prosysopc.ua.server.IoManager.readAttribute(SourceFile:870)
at com.prosysopc.ua.server.IoManager.readAttribute(SourceFile:439)

I am getting null value, but the node has value!

I was looking the documentation and there is others methods like readValue or other readAttribute (with more parameters) but I can not see them on my IoManager.

Thank you.
