Rule extends doens't work correctly

[yacine...@gmail.com]

Hi all,

I have two drools files :

file1.drl :

package name.pkg

import ex.sample.drools.*;

rule "Parent"
enabled true
when
    $person:Person(age==10)
then
   
end

file2.drl :

package name.pkg

import ex.sample.drools.*;

rule "rule1" extends "Parent"
no-loop true
when
    Person(age==11)
then

end

rule "rule2" extends "rule1"
no-loop true
when
    Person(age==12)
then

end

The file1.drl is compiled first then the file2.drl is compiled.

I got the following error :

Unable to resolve parent rule, please check that both rules are in the same package : [Rule name='rule2']
Unresolved parent name rule1 >> did you mean any of :[rule1]

But when i declare the drools file as following it's works:

file1.drl :

package name.pkg

import ex.sample.drools.*;

rule "Parent"
enabled true
when
    $person:Person(age==10)
then
   
end

rule "rule1" extends "Parent"
no-loop true
when
    Person(age==11)
then

end


file2.drl :

package name.pkg

import ex.sample.drools.*;

rule "rule2" extends "rule1"
no-loop true
when
    Person(age==12)
then

end

 I could not reproduce the issue, could you please your full test case?

In particular, how do you build the kiebase exactly? (kmodule.xml, programmatically, or.. ?)

Also, which version are you using?

Thanks

Davide

Hi David,

You can find the attached maven project that's perform this issue. I'm using drools version 6.1.0.
You can run ExampleDrools.java as java application.

Hi Yacine,

the way you're using to build the knowledge base is wrong.
Please use the new Drools 6 API. I modified your project and resending it in attachment. As you can see there, the new API are far more convenient and straightforward.

Cheers,

Mario

Hi Mario,

Thank you for your help. I now that my example is not a good way to build a session. But it's due to the history of our application. Anyway, the version with kmodule.xml is currently on developpement. I'll use it differently until using the kmodule.
This issue is closed for me ;-).

Yacine.
