I recently switched a diagram control in one of our apps from using standard RoundRect shape nodes with an attached Rect node as a subordinate node to the new Composite Node type. I do like the control and flexibility I get with the composite nodes.

However, I'm running into problems when exporting the diagram into PDF format. The export completes successfully, but the nodes in the PDF document do not have any text on them. I get images, borders, links, gradients, etc. but no text.

Exporting to PNG looks like it's working fine. Those are the only 2 export options I allow in the app right now.

On a related note, I tried to enable an Overview control for this diagram and I started getting the same disappearing text on the DiagramView itself (on composite nodes) while the overview was in use. Sometimes when rendering the diagram even the composite node layouts themselves would break (elements out of place, etc.)

Any ideas?

The 5.6.3 beta assemblies fixed the PDF export, but I'm still seeing node text display problems with an active Overview control. It seems to be worse when the scale of the Overview is very low (FitAll = True).

I've emailed the support address with a diagram XML export and screenshots of the problem.

Thanks for your help!
