OK, found the problem!
In my package I was having a model "testModel" that had no facts
declared.
This was causing the NPE when building the package.
So I think we need to check for this case or not allow the user to do
this.

Yes, I did a standalone test and in passes.
In my test I used the text version of the package from guvnor, that I
believe is generated by ContentPackageAssembler.getDRL().
however PackageBuilder has no issues with that version.
Now my next place to investigate is guvnors ContentPackageAssembly...
and the NPE happens as I can see from the stack trace in:
ContentPackageAssembly.loadDeclaredTypes.
If you have any sugestions to better approach solving this problem let
me know. As it is right now I will look into the code and try to
understand what is going on.

Hi Mark, I need to have the unit test inside guvnor or another
project that depends on it.
The code fails in guvnor when I do build package.
and I believe the problem might be related to BRMSPackageBuilder
that inherits from PackageBuilder or ContentPackageAssembler
where should I create the unit test ?
Have you tried doing this as a standalone unit test first? As the
problem will be in the PackageBuilder, not in the Guvnor. Just following
one of the examples in MiscTest.

the actual package namespace contains dots, I removed
them for privacy purposes.
ok, can i ask you to make a unit test for me, that I can put
into MiscTest ?

I think it might be a bug when a package namespace
doesn't have a dot in it.

here is my package source:
package MyTest
import pack.EventVO
import pack.ExtendedEventVO
declare ExtendedEventVO
@role( event )
end
rule "Test"
dialect "mvel"
when
ExtendedEventVO( )
then
System.out.println("Hello World, events
happen!!!")
end
rule 'TestEntryPoint'
dialect 'mvel'
when
ExtendedEventVO() from entry-point eventDoor
then
System.out.println("Hello World, events
happen!!!")
end
This seems like a possible BUG.
Let me know, thanks
