StackoverflowException with circular diagram

Hello,



we are evaluating Aspose.Diagram for our software dependency diagrams.

We have a problem when we use Diagram.Layout with a diagram which has a circular connection between shapes.



Shape 1 -> Shape 2

Shape 2 -> Shape 3

Shape 3 -> Shape 1 // circular connection



When we use LayoutStyle.CompactTree we get a Stackoverflow exception when we call Diagram.Layout.

When we use Layout.FlowChart we get no expcetion but the position of the shapes is not changed.



You can reproduce it directly with the attached VS solution (command line program).



Do you know a workaround for this problem?



Thanks,



Tom
