[rules-users] no visitor implementation for : class org.drools.rule.TypeDeclaration

[Tina Vießmann]

  Hi,

I'm getting a two red highlighted outputs in eclipse if I modify my 
rules file during run time. Besides that the modifications seem to work.
What does it mean?

The full output I get when the resource change is detected is listed 
below. The bold lines are the concerned ones.

Thanks for any help! :)
Tina
