Hi,

I'm evaluating your FlowChart.net component.
First of all.. great component, great documentation, easy to learn.. I will buy it anyway..

I just wanted to inform you that there is a problem in your sample 'PDF Export'. When I click the 'Export to PDF' button I get a System.NullReferenceException in MindFusion.Pdf.dll error. In my testprogram I just created some simple shapes, linked them and the export to pdf worked ok except of little problems: if a text of a link was 'sdfsfs' the text in the PDF file was just 'sdfsf', or if it was 'sdfsfs xx' I just saw 'sdfsfs'.. so the link text is somtimes truncated.

I tested your Export to PDF sample on a Win7 64bit PC with .net 2.0 (VS 2005 professional) and 3.5 (VS 2008 Express). Below you see the error detail I got running your sample program.

Thanks,
Franz
