Hi, I am having a strange issue when using the DiagramLink.IntermediateShape.

I have two nodes on the view connected via a DiagramLink with the IntermediateShape set to ArrowHead.PointerArrow.

Everything is fine and the arrow points to the correct node.  However, when I move one of the nodes, the arrow flips directions until the node is released again.

I have placed breakpoints everywhere I can think of, but the flip seems to happen before the events such as selectionMoving, nodeModifying and the event linkModifying is never raised.

Can anyone help in explaing how to to stop the arrow flipping during the node movement?

Many thanks for any pointers.

Hi, when I look at the details for the MindFusion.Common.dll it says the Product Version is 1.0.2608.20825

When the relation is created we setup the following:

arrow.AutoRoute = false;
arrow.BaseShape = ArrowHead.None;
arrow.HeadShape = ArrowHead.None;
arrow.Brush = new MindFusion.Drawing.SolidBrush(lineColor);
arrow.Pen.Color = Color.Blue;
arrow.Pen.Width = 0.6f;
arrow.IntermediateShape = ArrowHead.PointerArrow;
arrow.IntermediateShapeSize = 2;
arrow.ToolTip = "";
arrow.ControlPoints[0] = new PointF((float)(p1.X + dx), (float)(p1.Y + dy));
arrow.ControlPoints[1] = new PointF((float)(p2.X + dx), (float)(p2.Y + dy));

Hope this is the information you requested, if not please let me know.

Looking at the code, yes that seems to be true. The above code is only called once at creation, and the arrow is pointing in the correct direction, it is only while moving one of the nodes the arrow flips over.

Ah-ha, The head arrow appeared on the 'wrong' end.  Further investigation led me to a specific code path that created the initial arrow backwards even though the source and destinations were correct.

Thank you for the prompts, bug fixing others code can be frustrating
