[rules-users] Problems with rule builder errors

I'm using trunk (revision 10170), and I'm getting an exception when trying to read errors after calling PackageBuilder.addPackageFromDrl(String, Reader). The getErrors() method spits out this exception: java.lang.ArrayStoreException at java.lang.System.arraycopy(Native Method) at java.util.ArrayList.toArray(ArrayList.java:304) at org.drools.compiler.PackageBuilder.getErrors(PackageBuilder.java:380) (The docs for toArray say that exception is thrown if one of the members of the List is the wrong class for the supplied array.) If I instead call printErrors, I get something more useful: java.lang.ClassCastException: org.drools.lang.ExpanderException at org.drools.compiler.PackageBuilder.printErrors(PackageBuilder.java:390) It looks like someone is putting the wrong kind of exception in the error list. This may be related to some bugs in DSL handling. I had to comment out all the blank lines in my DSL file to get it to suppress some other errors, and if I switch to PackageBuilder.addPackageFromDrl(String), the problem goes away. -- Dirk Bergstrom dirk(a)juniper.net _____________________________________________ Juniper Networks Inc., Computer Geek Tel: 408.745.3182 Fax: 408.745.8905
