Due to a huge mess in my ecplise project i was ogliged to reset settings (delete directories), copy paste my src directory to new project. For this project, i use Vaadin Charts downloaded last friday, but after the massive clean, i can’t use it anymore, even widset rebuilding.
A message with required licence key appears.
Is there any demo licence key or anything i can do to perform my project presentation (Boss pres.) asap.
One additional thought - unless this is exactly what you did, you could try 1. setting up a New Vaadin Project, then 2. add the Charts add-on, then 3. copy in your old source code.
