planner: Solver-Phase after a ProblemFactChange?
by roman.stumm
When the solver is in the localSearch phase and a problem-fact-change occurs:
will the solver jump back
into the construction-heuristics phase or continue with the local search?
Reason for my question: We have a (chained) vehicle-routing-problem with a
custom SwapMove- and ChangeMove-SelectionFilter that return 'false' for
some moves (on immovable planning entities, e.g. when a stop should be
pinned to a specific tour etc.), but the solver modifies them nevertheless
after a problem-fact-change?

User permission (Maker-Checker) issue in Guvnor 5.4.0
by kulpreet_singh
Hi,
I am using Guvnor version 5.4.0 and trying to implement maker-checker
functionality for updating rules/assets in Guvnor. I am facing problem
related to user permission. Following are the steps:
1) Configured two users in Guvnor using 'admin' login - Analyst & Developer
2) I have one package 'Test' where all the rules resides.
3) Created two categories - Draft & Approved
4) Assigned 'Developer' user: 'analyst' role on 'Draft' category and
'package.readonly' role on 'Test' package.
5) Assigned 'Analyst' user: 'analyst' role on 'Approved' category,
'package.developer' role on 'Test' package and 'analyst.readonly' on 'Draft'
category.
6) The idea is to initially assign all the rules/assets under 'Draft'
category. Once 'Developer' finishes working on rules, the 'Analyst' verifies
and replace the rule/asset category to 'Approved'.
7) I checked, the system is not allowing 'Developer' to edit the content of
the rule which is marked as 'Approved' category. But, the problem is,
'Developer' is allowed to replace the 'Approved' category of the asset back
to 'Draft' and hence free to edit that rule.
I presume this as the bug in the system as Developer should not be allowed
to modify the category of the rule if it doesn't belong to 'Draft' category.
Please help me in suggesting the workaround for this issue and appreciate
your valuable inputs in this regard.
Thanks & Regards,
Kulpreet Singh

Not Able to create a cindition BRL fragment
by Aditi Hardas
Hi ,
I am using Drool Guvnor 5.5 along with IE 9 and Tomcat 7.0.32. I have
successfully deployed Guvnor in Tomcat.In next step I have created a package
then add a new category and added a rule with Decision Table (web - guided
rule ) as a rule formate.I was able to create a rule with certain set of
conditions and actions.On clicking Include Advance Option and choose *Add a
condition BRL fragment* or *Add an action BRL fragment*, I am getting java
script error and nothing is moving forword after that. That mean I am not
able to add and BRL fragment to my rule.
Can any one help me for this. Does I am doing any thing wrong.
Thx in advance.

Guvnor REST APIs - what rule features are supported?
by kurrent93
Hi
I saw a thread a few days ago asking about how to enable/disable rules using
the guvnor REST Api - only to find that that functionality does not exist.
What other functionalities are not covered by the REST apis?
For example, can we add calendars using the REST api?
What about salience, no-loop, activation group, agenda group, duration?
We are looking to build a custom UI for editing rules, using the Guvnor REST
apis, and but if there is limited coverage, then we will need to find an
alternative.
Thanks
