Hi All,
I believe that I have encountered two potential bugs (Expert), I am using
Drools 5.1.1.
It seems that they are related to namespaces and inner classes in
particularly.
I have a class with an internal inner class (enum):
public class X {
public enum State {
INIT,
DONE;
}
Private State state;
}
In the DRL file I would import the class X (e.g. import com.stub.X)
And in the LHS of the rule I could state something like
$x: X(X.State.INIT == state)
As far as I understand this is a legal syntax, the problem is that I get the
following exception: "Exception executing predicate X.State.INIT == state"
I found that I can work around this by importing com.stub.X.State and
changing the LHS rule to
$x: X(State.INIT == state)
This brings me to the second issue. If I have an additional class let's say
public class Y {
public enum State {
ALIVE,
TERMINATED;
}
Private State state;
}
In this case importing both classes using the workaround above, hence:
import com.stub.X.State
import com.stub.Y.State
result in an import collision with the State class so it is kind of a
deadlock situation.
I can always overcome this by changing the names of the inner classes (which
is what I am currently doing) but I thought it would be helpful to state
this.
Perhaps this is not a bug but rather something I am doing wrong.
Hezi
