Hi,

Is it possible to mix dsl language and regular rule syntax in a rule file? I am trying to do this, but my rules won't compile. The "unable to expand" error is returned during compilation. I tried adding [*][]"{anything}" = "{anything}" to the dsl file to fix this, but that didnt work. I used this strategy in Drools 4.0.7, but it doesn't seem to work in Drools 5.0.0 M5. Below I provided a simple example of what I would like to do.

Thanks,

Dan

    then
        System.out.println("Person does not like dog");
end

[condition][]There is an animal lover and dog in the system=person : Person(animalLover == true) dog : Dog()
[consequence][]The person owns the dog=dog.setOwnerLastName(person.getLastName()); update(dog);

Subject: [rules-users] Error running DroolsCompilerAntTask in CR1

Hi,

I upgraded everything from M5 to CR1 last night, but noticed that my ant task no longer worked and was returning an error (it had worked previously under M5, and I confirmed by switching everything back to test). The error I now receive is:
