One of the most asked questions from users of the Web Publication Platform was 'why are the diagrams not clickable??'. In other words why is the behaviour in the web diagrams different from the behaviour in diagrams in EA where you can click on an entity and a window with the details will appear.
I did some research in the static html routine in EA and discovered that there is a conversion rule and it does not seem to be very complicated. Result is that the diagrams are clickable in the WPP. The next period I will fine tune the conversion routine and publish the material at WPP.
