CharSequenceCompilerException: Compilation failed

Hi,

I’m having as below exception. I’m using a vaadin add-on, I installed fist a lower version of that add-on, and when I upgraded, I see this exception :

CharSequenceCompilerException: Compilation failed. Causes: 
Network_TSView.java:11: error: cannot find symbol
import org.vaadin.visjs.networkDiagram.Color;
                                      ^
  symbol:   class Color

Can anyone help ?

I found the issue, I had to UnDeploy in order to use the latest imported version.

regards,
Gent
