Hello,

I am using drools 4.0.7 with eclipse 3.3 plugin, and JVM 1.6.0_04-b12

I am a drools beginner and I first try to implement basics rules.

I have faced a very strange behaviour I don't understand. Below the use case & rules :
----------------------------------------
Rules
----------------------------------------

package poc

import poc.FlashFact;

rule "always"
    when
        $f : FlashFact()
    then
        System.out.println("*** always ... "+$f);
end

rule "one (eval)"
    when
        $f : FlashFact()
        eval($f.getHomepage().equals("one"))

    then
        System.out.println("*** one (eval) ... "+$f);
end

rule "one (==)"
    when
        $f : FlashFact(homepage == "one")
    then
        System.out.println("*** one (==) ... "+$f);
end

----------------------------------------
Use Cases
----------------------------------------
I insert 2 FlashFact instances (one with homepage == "one", another with "dummy")

when I lauch the rules (without shadows proxy), the output is :

*** one (eval) ... poc.FlashFact[one]
*** always ... poc.FlashFact[one]
*** always ... poc.FlashFact[dummy]

=> I don't understand why rule one(==) is not fired ?

when I lauch the rules (with shadow proxy), the output is :

*** one (==) ... poc.FlashFact[one]
*** one (eval) ... poc.FlashFact[one]
*** always ... poc.FlashFact[one]
*** always ... poc.FlashFact[dummy]

The == and eval does not behave the same way with/without shadow proxy.

Moreover, I have run the State example provided with Drools in my workspace and it worked fine (== without shadow proxy).

Can someone has a deep understanding of this difference of behaviour ?

Thanks for your reply.
