[rules-dev] NPE when building package

[Zoltan Farkas]

the actual package namespace contains dots, I removed them for privacy
purposes.

	I am getting a NPE when building a package with guvnor:

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
