Hi,
Any idea about this exception? Tried to google it up, but didn't get
anything satisfactory.

I have the following dependency in my project pom:
<dependency>
<groupId>org.jboss.shrinkwrap.resolver</groupId>
<artifactId>shrinkwrap-resolver-api-maven-archive</artifactId>
<version>2.0.0-alpha-7</version>
</dependency>
But it seems like the jar doesn't have that class anymore. Any thoughts?
Thanks

Drools Planner Chaining/Cloning Documentation Suggestion
by Trails
Hi all,
I'm new to drools planner and liking it a lot!
I spent some hours last night cracking my head on something. I have
switched my domain from planning variable pointing to planning facts to
using chained planning variables.
I ran into a problem with score corruption, which was surprising as I am
still using a Simple Score Calculator.
It turns out my problem was when cloning the solution the planning variable
(now chained) was still pointing to entities in the old solution. I was
following along the user guide when I fell over this.
I'd like to humbly suggest that the drools planner user guide include a
note/warning/something in the chained variable section about ensuring that
when cloning the solution, the chained planning variables are updated to
point to the cloned planning entities. There is currently no mention of
solution cloning in this section, and the code included in the doc does not
mention this either.
This is illustrated in the examples, e.g. TSP, but it's in the Solution, not
the planning entities.
Just hoping to save others the head scratching.
Thanks!
Taylor

guvnor 5.5 - Guided decision tables (web based)
by Apurva Joshi
Hi,
I am trying to create a rule using Guided decision tables (web based).How
can I use any of the collection classes in my rule?I know that we have to
first import the model POJO jar in order to use the class types in our
rule.when I try to upload JDK jar(rt.jar),which contain implementation for
the collection classes and try to validate it,the guvnor tool gives me error
that the POJO jar is not valid.
I would appreciate any help of this issue.

Mapping to '==' in enumeration
by rjr201
Hi,
I've created an enumeration in Guvnor like so:
'Object.operator[]': ['== = equals', '!= = does not equal', '< = less than',
'> = greater than']
The less than and greater than map fine. But the equals and does not equal
don't. I realise that I need to escape the first two = signs, but can't find
a way to do it.
'\=\= = equals' doesn't work. Anyone got any ideas?
Sorry if this is something really easy to solve, but I can't work it out.
(also I realise that I could just have a drop down box with the mathematical
symbols in and not worry about mapping it to english, but apparently that
would be too technical for non-technical users )

Unmarshall large session fails
by Magnus Vojbacke
I'm trying to unmarshal a knowledge session that has been persisted to file, but I get the following exception:
Stack Trace:
com.google.protobuf.InvalidProtocolBufferException: Protocol message was too large. May be malicious. Use CodedInputStream.setSizeLimit() to increase the size limit.

at org.drools.marshalling.impl.ProtobufMarshaller.unmarshall:143
The session consists of >1M facts, and the file is ~167 MB in size.
While Googling, I stumbled upon the recommendation to run CodedInputStream.resetSizeCounter() inbetween deserializing messages. Is this a fix that could be implemented in Drools?
Is there any way of configuring or parameterizing the unmarshalling size limit used by Drools?

Planner: What is a good example/algo to chain entities?
by Michiel Vermandel
Hi,
I need to keep some Planning entities (Tasks) together and I am looking for some insights/ideas/examples in how to tackle this.
Tasks are grouped by a groupId (Groups are problem facts).
The Tasks do not have to be grouped like a pillar but more like an accordion.
One of the planning variables is "Period", a Period typically is 3 weeks and we have 12 Periods to plan the tasks into.
The requirement is that all tasks within a group need to be kept together in such a way that:
- the spread (nr of periods) of the tasks is minimal
- the spread is never more than the sum of the duration of the separate tasks in the group.
So given a group of 3 tasks:
1)This is good:
Period 12345789ABC
T1: xxx
T2: xx
T3: x
2)This is better:
Period 12345789ABC
T1: xxx
T2: xx
T3: x
3)This is (one of) the best:
Period 12345789ABC
T1: xxx
T2: xx
T3: x
4)This is bad:
Period 12345789ABC
T1: xxx
T2: xx
T3: x
Of course 3 is favorite, but maybe not possible due to other planning variables (-> availability of people to execute the tasks).
I need to plan a few hundred of such groups of tasks which all share the same Period space and list of available people.
(A person can only do one task per period)
I have got the DRL rule that keeps the tasks together (rule counts the gaps) , but giving penalty for making gaps (by shifting a single task) makes it hard to find a good solution.
What would be the best approach to solve this problem?
- A combination of custom mover and swapper which moves/swaps groups instead of single tasks?
- The above in combination with a group shuffle factory (swapping tasks in a single group)?
Other ideas?
Thanks a lot!
