Hi all,

I'm using JBoss Rules 4.0.0.12865MR3 and trying to use a DSL expander in my
DRL file:

  package docmap.logic
  import docmap.facts.*
  expander test_expander.dsl

I didn't forget to also initialize the PackageBuilder:

  builder.addPackageFromDrl(sourceReader, dslReader)

At runtime I always get the following exception, no matter which content the
DSL file has:

org.drools.rule.InvalidRulePackage:
org.drools.lang.ExpanderException@10f3a9corg.drools ............
........................................ <many more ExpanderExceptions>
org.drools.lang.ExpanderException@1c9313borg.drools.lang.ExpanderException@1bf3519
at org.drools.rule.Package.checkValidity (Package.java:409)


Thanks in advance for any hint,
Andreas
