	Hi, I got an ArgumentNullException with testing custom node serialization using IconNodes demo application in FlowChart.NET 5.0.1. I think IconNodes application has a problem in serialization part. My IconNodes MainForm.cs code here. --- (button1 for copy, button2 for paste) ... private void button1_Click(object sender, EventArgs e) { diagramView.CopyToClipboard(false); } private void button2_Click(object sender, EventArgs e) { diagramView.PasteFromClipboard(0, 0); } --- How should I do to fix it? Thanks in advance. Jinwoo

	Hi, For Copy & Paste to work correctly, you must either implement the DiagramItem.Clone() method, or add a copy constructor. E.g. Code public IconNode(IconNode prototype) : base(prototype) { icon = prototype.icon; label = prototype.label; format = prototype.format; } I hope that helps, Stoyan
