	Hi, I have a shape with an outline and some decorations, that I'd like to be part of hit testing, so that I can create links by clicking on them. If I understand correctly, setting the DecorationHitTesting property to "true" on the shape should do what I need, but for some reason it doesn't. Thoughts? By the way, the shape nodes are part of containers, although that shouldn't be an issue I think (I didn't see a difference when dragging them outside of the containers). Thanks, -Mihai

	Also, what is the meaning of "near" in the docs: "If this property is enabled, users are able to select shape nodes of such shape by clicking *near* a decoration line or curve, even if it lies outside the shape outlines."? Is it customizable? Thanks again, -Mihai

	This seems to happen if you use a Shape with no string identifier defined, which makes it private for the node and the Shape property setter clones it. Apparently the Shape.Clone code does not copy DecorationHitTesting value at this time, so you could set it after assigning to node.Shape as a work-around: Code shape.Shape = myShape; shape.Shape.DecorationHitTesting = true; "near" is fixed 5 millimeters, we could add a property for next release if you need it. I hope that helps, Stoyan

	Hi Stoyan, Quote: Shape.Clone code does not copy DecorationHitTesting value at this time Will this be fixed in the next release? Quote: so you could set it after assigning to node.Shape as a work-around Thanks, it works! Quote: "near" is fixed 5 millimeters, we could add a property for next release if you need it. Now that I see it in action, I think 5 mm is a good choice. Thanks, -Mihai
