Selection after load of custom ndoe type (Read 6294 times)

	After saving a diagram and then loading it again from disk, I've noticed that before I can select individual nodes and have the moving/sizing handles show up, I must first highlight all of the nodes, then click on the entire selection for the handles to show up on all of the nodes. Only after that can I individually select the custom nodes. Is this a bug, or do I need to maybe set some other property after loading the diagram from disk? Thanks.

	Are you using binary or xml serialization? What happens if you call Selection.Clear() just after loading?

	I'm serializing with the BinaryWriter and BinaryReader provided in the SaveTo and LoadFrom methods. Clearing the selection just after load doesn't seem to remedy the situation. Thanks.

	and you are calling base.LoadFrom() from your custom node LoadFrom implementation?

	Yes - the base is called in both LoadFrom and SaveTo. Additional info - after the file is opened, I can add more custom nodes, and they are immediately selectable. However, the existing ones loaded from the file still are not individually selectable until they are all selected and clicked at least one time.

	It works fine if you call the base class constructor - public CustomNode(Diagram dgm) : base(dgm)

	Very nice. A bit upset with myself that I didn't think of it before. Thanks!
