Hi,

I have created a custom node called ComputerNode, just like the IconNode example.
When i call save to xml i get:

java.lang.IllegalArgumentException: netDiagram.ComputerNode@1cac6db cannot be serialized because its class hasn't been registered for serialization. Use RegisterItemClass to do that.

I have called
Diagram.registerItemClass(ComputerNode.class.getClass(), "ComputerNode", 1);
in the constructor yet it still does not work. Do i need to do something else?

Thanks

Karl

Hi,

It seems i have not fixed the problem.

I am able to save to xml but when i try to load the xml file i get the error message:


com.mindfusion.diagramming.XmlException: java.security.InvalidParameterException: Failed to instantiate item of type 'netDiagram.ComputerNode'.


Computer node is my cutsom node, it inherits from shapenode.

Thanks Stoyo,

I added a ComputerNode(Diagram) and it now works
