Invalid Security key ! ! !

Running a vaadin app (created using maven and sample archetype, and everything is going fine.

I then tried to use debug (from URL), things went a bit funny and I had to kill eclipse and restart.

Then I start getting log message…

/TestApp:Vaadin Application Servlet: Invalid security key received from 0:0:0:0:0:0:0:1

Now, after doing complete rebuilds (mvn clean install), I still get this message and the same in Firefox browser.

I then created a project from scratch ColorPicker example, and that runs fine.

I’m stuck on whats gone wrong and what to try next. Any ideas please?

Many Thanks
