DiagramConnectionPoint's not displayed correctly when printing or exporting to PNG

In my diagram project the connection points is always visible, but when printing or exporting to PNG they are not displayed correctly (see attachments).

I have not been able to reproduce this issue. I have however recently resolved a bug related to connection point positions. It's possible these were related. Install the latest nightly build, and let me know if the problem still remains. If so, please send a repro project so I can look into this further.

Hi' Jason

I have tried latest nightly build....... same problem :-(

I have made a repro project for you, to test this further.

Thanks,

Thanks for the repro project.

This issue has been caused by some changes in version 3.0. In App.xaml you have a copy of the old diagram node style. To resolve this issue you just need to make a couple of small modifications to this style. First, on line 153 of App.xaml, delete the Canvas.Left and Canvas.Top setters. On line 156 and 157, instead of using the Canvas attached properties, change these to be binding to Left and Top directly. i.e:

<TranslateTransform X="{Binding Left, RelativeSource={RelativeSource TemplatedParent}, Converter={StaticResource Negative}}"
                    Y="{Binding Top, RelativeSource={RelativeSource TemplatedParent}, Converter={StaticResource Negative}}" />

Thanks, works like a charm.

Print and Export works fine, but after printing I can no longer move items e.g. it triggers an Null reference exception.

Thanks for pointing out this critical issue. This will be resolved in the next nightly build.
