Michael Neale commented on JBRULES-1923:
----------------------------------------

OK this is a problem with the compiler. 

Now we have 2 options: 

1) Make guvnor render "parent" rules first
2) make the compiler not care about the order

thoughts?

> When inheriting rules, the order they are written to DRL counts. 
> dward noticed this when using Guvnor. There is no way to control the order of the rules in Guvnor, so because of this inheritance doesn't always work.
> This works:
> rule A 
>     when    
>         ...
>     then
> end
> rule B extends A
>     when
>         ...
>     then
> end
> This doesn't work:
> rule B extends A
>     when
>         ...
>     then
> end
> rule A 
>     when    
>         ...
>     then
> end
