[drools-user] Drools 3, LHS exception handling

[Juergen]

Is it possible to tell drools not to forward an exception thrown during 
LHS evaluation, but to consider it as LHS not fulfilled? probably as 
additional rule attribute?

e.g.
rule "a"
        failureException NullPointerException, SomeException
        when
                a : A()
                B(b == 
(aBind.getSomeAttrib().getSomeAttribThatsNull().getAttrib())
                eval ( someExpressionsThatThrowsSomeException() )
        then
                ...
end
