That’s good advice.  I tried putting everything in a default package, including the rules, but still no luck. 

For the time being, I’m going to put aside working with rule tables in spreadsheets and see how they work in Guvnor.  There must be some subtleties with the spreadsheets that I am not getting yet.

If I understand you correctly, this is a Java runtime restriction.  

Java classes in the default package can reference any class in a named package.  Other the other hand, classes in a named package cannot reference any class in a default package.  Classes in a default package can reference other classes in a default package.

Thus, the easiest way normally to deal with this problem is to either (1) put everything in a named package, including any grails classes/domain objects/etc or (2) put everything in a default package.  I'd suggest that you go with option 1 because it'll give you fewer problems.

But I'm not sure if that's the question you're asking or if this helps you.  Hopefully, it does. :)

   Robert,

   What version of Drools are you using?
   I remember seeing something about this in the past... I will search JIRAs to see if we have any ticket open for 5.0.

Has anyone else run into issues trying to reference objects in a default package?  I'm trying to use Drools with Grails and my rule which compiled nicely in a package setting has issues when faced with a default package. 

The error is "foo" cannot be resolved to a type

I've tried putting the rule both in the default package and putting it in a named package, and neither seem to work.   If I put my objects back into packages, everything is fine.

Any  advice?

Thanks,

Robert Costello
