Hi!

Really similar to http://mindfusion.eu/Forum/YaBB.pl?board=fcnet_disc;action=display;num=123254705..., it crashes when I try to manually copy node + links.

A first chance exception of type 'System.NullReferenceException' occurred in MindFusion.Diagramming.dll
Exception message:
Object reference not set to an instance of an object.

Stack:
at MindFusion.Diagramming.DiagramLink.x0d5905a18dc24aa7(Boolean x1c5ff8c3c1ac16ad)
at MindFusion.Diagramming.DiagramLink.UpdateFromPoints(Boolean updateGroups)
at MindFusion.Diagramming.DiagramLink.UpdateFromPoints()
at MindFusion.Diagramming.Diagram.CopySelection(Diagram source, Boolean unconnectedLinks, Boolean copyGroups)
at Entities.MainForm.buttonCopy_Click(Object sender, EventArgs e) in M:\AnimTree\Varies\TestsC#\ManualCopyWithLinks\MainForm.cs:line 266

To reproduce this error:
Add 1 copy button to the Entities sample:

private void buttonCopy_Click(object sender, EventArgs e)
{
    try
    {
        this.diagram.CopySelection(this.diagram, false, false);
    }
    catch (Exception exc)
    {
        System.Console.WriteLine("Exception message:\n" + exc.Message + "\n\nStack:\n" + exc.StackTrace);
    }
} 

Then, create 3 entities, link them and CTRL-Click to select all components except for one of the nodes (you'll have 2 nodes and 2 links selected). Click Copy and BOOM! In fact, just selecting 1 link works. Nevertheless, if you select 2 nodes including the link in between them (but no other), it doesn't crash.

Thanks,
Marie

p.s. I'm using version 5.2.0.21110.

Hi,

Thanks a lot! Is it safe enough to be used in regards to other changes that might be included?

Regards,

p.s. I think it was a good idea to rename dlls so they are more easily recognizable

Perfect 

Thanks again,
Marie
