Re: [rules-users] not sure if this is a bug of drools or my bad usage...

Hi all, An interesting finding: I have three simple rules: rule "A2B" when A() then insertLogical(new B()); end rule "B2C" when B() then insertLogical(new C()); end rule "C2B" when C() then insertLogical(new B()); end Basically, once we have an A(), we'll logically insert a B(). Once we have a B(), we'll logically insert a C(). Once we have a C(), we'll logically insert a B(). So, I first insert an A(), print all the objects. Retract A(), and print all the objects. Here's what I got: com.sample.B@42 com.sample.C@43 com.sample.A@548997d1 after retract! com.sample.B@42 com.sample.C@43 So, B() and C(), which should be logically depend on A(), somehow are not retracted. The problem I see is the truth maintenance system allow B() and C() to depend on each other, thus not affected by losing A(). Is this a bug or my bad usage?
