URL: https://github.com/apache/incubator-kie-drools/issues/6216
Hello,
We are using the fact model to build the Knowledge Base like below
Events.drl
```
Package com.example
declare Person
age: int
address : Person.Address
end
declare Person.Address
city: Stirng
end
```
Rule.drl
```
Package com.example
global java.util.List resultList;
rule "rule0"
when
$p : Person( age >= 0 && age < 5 && address.city == "New York")
then
resultList.add( kcontext.getRule().getName() + " : " + $p );
end
```
Using the Below Code using drools version : 7.73.0.Final
Dependency :
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-core</artifactId>
<version>7.73.0.Final</version>
</dependency>
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-compiler</artifactId>
<version>7.73.0.Final</version>
</dependency>
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-decisiontables</artifactId>
<version>7.73.0.Final</version>
</dependency>
Using the traditional method, would be using the below code to compile the
drl files, where everything works.
`KieBuilder kieBuilder = kieServices.newKieBuilder(kfs).buildAll();`
Now, to move to KAJR and migration of project we started with the code
changes

/>
` kieBuilder.buildAll(ExecutableModelProject.class);`
But, now we see the buildAll fails saying the error :
<img width="836" alt="image"
src="https://github.com/user-attachments/assets/e64e4aa4-27f4-4b0b-a612-6ad1fc4940da";
/>

src="https://github.com/user-attachments/assets/3fcdb7f8-20ac-4418-a188-51bd995f7e1c";
/>
We understood the error that class object is not getting formed correctly
because of the way the Events.drl written.
Is there any way to achieve the generation of KJAR or Rule Unit without
chaining the Fact Model Event.drl and Rule.drl syntax.
Also, our rule keeps on changing (Programmatically load rule ) , so only
were exploring to options move to KJAR or Rule Unit of work.
Thank you in advance.
