Dear
In some case extended rule failed to find  variable.
This occur when using "or", "exists" and "extends" 

A minimal test case is available on [github|https://github.com/bioinfornatics/DROOLS_NPE_rule_extended]

In this [test case |https://github.com/bioinfornatics/DROOLS_NPE_rule_extended/blob/master/src/main/resources/fr.cea.test/rules.drl]:
 if we comment line number 62 , any error are raised
 if we uncomment line number 10 , any error are raised
 if we remove all "exists" words, any error are raised

If the same rule is write using named consequence the test pass.
