[JBoss JIRA] (DROOLS-1158) NullpointerException when trying to reuse KnowledgePackage into a new KnowledgeBase
by Juan Carlos Garcia (JIRA)

Juan Carlos Garcia updated DROOLS-1158:
---------------------------------------
Description:
Having a set of DecisionTables which KnowledgePackages are cached in our application, after we detect a change in any of those XLS files, we build a KnowledgePackages from it, and then try to create a new KnowledgeBase with the new KnowledgePackages + the rest of the cached one that that were not modified, but it fails with a NPE internally in Drools (6.3.0 and 6.4.0)
This is not a problem for the drools version (6.0.1.Final) that we currently uses using in production.
After debugging and putting a breakpoint into the *MvelConstraint.java:619*, it shows that it is trying to look for a packageName which hasn't being loaded yet in the new kbase (but belong to others XLS).
I have attached a project with a testcase that shows the problem, it has 2 DecisionTable which i had to cut down a little bit (from our real files) and removes some sensitive information (replacing some of text with FOO-BAR).

was:
Having a set of DecisionTables which KnowledgePackage are cached, after we detect a change in the filesystem, rebuild the new XLS file and try to create a new KnowledgeBase with the new KnowledgePackage + the rest of the packages that are are cached it fails with a NPE internally in Drools.
After debugging and putting a break point into the *MvelConstraint.java:619*, it shows it is trying to look for a packageName which hasn't being loaded yet in the new kbase.
I have attached a project with a testcase that shows the problem, it has 2 DecisionTable which i had to cut down a little bit (from our real files) and removes some sensitive information (replacing some of text with FOO-BAR).

I have attached a project with a testcase that shows the problem, it has 2 DecisionTable which i had to cut down a little bit (from our real files) and removes some sensitive information (replacing some of text with FOO-BAR).
