Unable to create Field extractor error caused by methods like public boolean setTime() -------------------------------------------------------------------------------------- Key: JBRULES-2406 URL: https://issues.jboss.org/browse/JBRULES-2406 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-compiler Affects Versions: 5.0.1.FINAL, 5.1.0.M1 Reporter: Jos Hendriks Assignee: Mario Fusco Fix For: 6.0.0.Alpha1 I used The clipse plugin to create a new drools project and added the example java class and rule file. I have added the method below to the Message class: public boolean setTime() { return true; } This result in the following error messages: Unable to create Field Extractor for 'status' of '[ClassObjectType class=com.sample.DroolsTest$Message]' in rule 'Hello World' : [Rule name='Hello World'] Unable to create Field Extractor for 'message' : [Rule name='Hello World'] org.drools.RuntimeDroolsException: java.lang.ArrayIndexOutOfBoundsException: 0 Unable to create Field Extractor for 'status' of '[ClassObjectType class=com.sample.DroolsTest$Message]' in rule 'GoodBye' : [Rule name='GoodBye'] Unable to create Field Extractor for 'message' : [Rule name='GoodBye'] org.drools.RuntimeDroolsException: java.lang.ArrayIndexOutOfBoundsException: 0 Rule Compilation error : [Rule name='Hello World'] com/sample/Rule_Hello_World_0.java (7:416) : myMessage cannot be resolved Rule Compilation error : [Rule name='GoodBye'] com/sample/Rule_GoodBye_0.java (7:343) : myMessage cannot be resolved java.lang.IllegalArgumentException: Could not parse knowledge. at com.sample.DroolsTest.readKnowledgeBase(DroolsTest.java:46) at com.sample.DroolsTest.main(DroolsTest.java:23) Adding a parameter to setTime or renameing it to something else then setXxxx, storeTime for example, does not result in an error.
