Edson Tirelli commented on JBRULES-1152:
----------------------------------------

Steve, I'm not sure what is happening, as I downloaded your v2 example, added drools dependencies and it is running fine (only 1 rule firing), doesn't matter the order of the statements in the consequence. I tried both 4.0.1 and current trunk versions (revision #15173).

Please note that the order of the statements does matter when using PropertyChangeSupport as you are doing, because your bean is firing the update event for every single change in the bean. So, changing the attributes in the following order:     

$acu.setMessage("on");
$acu.setState(false);

Is heavier than doing:

$acu.setState(false);
$acu.setMessage("on");

This is why we advise against the use of dynamic beans in such scenarios. Please take a look in the new MVEL modify feature for composite attribute changes, or the use of explicit update() calls.

Although, even if you use the dynamic beans in the way you are doing, only one rule should fire, and that is the behavior I'm seeing using your project.

Also worth of note is that apparently you are using old dependencies in this example project that are not needed anymore. Before releasing the 4.0 version we did a dependencies cleanup to avoid the need of several libraries that were previously transient dependencies of drools dependencies. For an update documentation of currently required dependencies, please read the README_DEPENDENCIES.txt doc in drools release zip.

> Sorry, I don't have very specific information.  Some of my project's unit tests are hanging with drools 4.0.1.  No error, just not completing.  I tried to debug a bit but could not figure it out.  Consider this an early warning until I can gather more info.
> Everything worked fine with 4.0 so I went back to that.
