I use plantuml every day and I am a very happy user. However, I have an issue with links.
In fact I use it in combination with the associated chrome plugin PlantUML Viewer . Links do not work in this plugin.
I know that this plugin is out of the scope of plantuml per se, but I found a related bug that might be the cause: if you look at one demo on the plantuml server . It does work correctly, but as soon as you change the layout (use the "Switch Layout" button), links will not work anymore.
Thanks for this nice tool!
