Hi,
I’m new to vaadin framework. The problem coming when trying to integrate Visulization for vaadin plugin in my project.
I’m getting following error when compiling widgetset.
-
When clicked on ‘Compile Vaadin Widgetset’ button got the following error.
[color=#FA3532]
Error in compiling widgetset: java.lang.NullPointerException- null
See error logs for details.
(Screenshot : screen1)

a) Why its not working, how can I find the error logs.
- Automatic project publishing to tomcat displayed a dialog with below message.
“Your client side code in the project myapp might need a recompilation.Compile widgetset now?”
(Screenshot : screen2)
When I click on ‘yes’ button compilation failed with following error(check the complete error at the bottom):
[WARN]
Line 35: Referencing field ‘java.lang.Object.castableTypeMap’: unable to resolve field, expect subsequent failures
[ERROR]

I have also created a sample project with the help of vaadin plugin, in that project visualization plugin is working fine. Don’t know why not working with my maven project.
I added following dependencies to enable VisulizationForVaadin add-ons in my project.
