I'm having a problem a little odd trying to fire rules using the Guvnor. In Guvnor I have a package named package kobo.regularSafaris, inside this package I have defined rules (with some DSL definitions), a decision table (xls) and two functions. The problem is that when I'm trying to call the functions in the consequence of a rule I'm having the following error: org.drools.runtime.rule.ConsequenceException: [Error: unable to resolve method: kobo.regularSafaris.AddBookingPayment.addBookingPayment(kobo.regularSafaris.BookingRequest, java.lang.Integer, java.lang.Integer) [arglength=3]] [Near : {... Unknown ....}] ^ [Line: 1, Column: 0] at org.drools.runtime.rule.impl.DefaultConsequenceExceptionHandler.handleException(DefaultConsequenceExceptionHandler.java:23) at org.drools.common.DefaultAgenda.fireActivation(DefaultAgenda.java:943) at org.drools.common.DefaultAgenda.fireNextItem(DefaultAgenda.java:885) at org.drools.common.DefaultAgenda.fireAllRules(DefaultAgenda.java:1086) at org.drools.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:660) at org.drools.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:632) at org.drools.impl.StatefulKnowledgeSessionImpl.fireAllRules(StatefulKnowledgeSessionImpl.java:187) at com.rudder.packages.test.rules.PricesRulesTestCase.testNobelLowSeasonPrices(PricesRulesTestCase.java:108) The function definition is as follows: function void addBookingPayment(BookingRequest request, int days, int percentage) { PaymentPolicy payment = new PaymentPolicy(); payment.setPercentage(percentage); if( days > 0 ) { DateMidnight dueDate = new DateMidnight(request.getDepartureDate().getTime()).minusDays(days); payment.setType("DEFERRED"); payment.setDueDate(dueDate.toDate()); } else { payment.setType("NOW"); payment.setDueDate(null); } List payments = request.getBookingData().getPayments(); if(payments == null) { payments = new ArrayList(); request.getBookingData().setPayments(payments); } payments.add(payment); } And the rule that is calling the function is the following: rule "Def. Deferred Payment for Credit Operator" dialect "mvel" when $request: BookingRequest() user: User(type == "Professional") from $request.user eval($request.getBookingData().getPayments() == null) || ArrayList(size == 0) from $request.bookingData.payments eval( "true".equals($request.getUser().getTags().get("hasCredit"))) eval( (new DateMidnight($request.getDepartureDate().getTime())).minusDays(35).toDate().after(new Date())) then addBookingPayment($request, 35, 100); end It seems that the system is adding an extra "AddBookingPayment" to the package name and this is causing the problem. Why is doing that? how can i solve this?

I'm using Drools 5.0.1 in JBoss AS 4.2.3. I've tested the two options with the following results: b) Changing the dialect from mvel to java: Runs OK!

a) Change the parameters signature from int to Integer throws the following exception:
