Re: [rules-users] Planner has trouble creating a configurer: how to debug
Yes, this should work as the javabean spec allows it and both Drools
Expert and Planner support it:
public boolean isFixed() {...}
but IIRC a wrapper Boolean shouldn't:
public Boolean isFixed() {...}

Drools, and hence I assume Planner, *should* handle boolean "is" accessor.
Can you provide more details?

Re: [rules-users] Planner has trouble creating a configurer: how to debug
I have news for you!
I had an obvious and (bad surprise) buggy mismatch.
The obvious mismatch was: setBlockList and getBlocklist (small 'l' in the
getter).
The other mismatch was isFixed and setFixed. *Drools hates the 'is'* because
(as I guessed) of it's introspector mechanism. It worked only when I renamed
it to getFixed. Your bugfix would have harmed instead of helped, as it would
have let that error pass silently.
Please open an issue to address this.
Wish I wasnt religious to name boolean getters with 'is'. I will notify of
further problems once the problem gets back on track.

Re: [rules-users] Planner has trouble creating a configurer: how to debug
Hi,
The NullPointerException should definitely not happen, you should get a
decent error message describing what's wrong.
It's fixed in 5.4.0.Beta1.
It looks like you're running into:
https://issues.jboss.org/browse/JBRULES-3247
Upgrade to planner 5.4.0.Beta1
or add a getter for that setter.

[rules-users] Planner has trouble creating a configurer: how to debug
I tried to create a solver from XML configuration. But the entire process
returns a *cryptic error message *that makes no sense.
How do I fix this? And how can I make sense of this to actually solve
similar problems like this?
Please excuse me if I made any bad karma. This is my first post on this (and
any) mailing list.
