Re: [rules-users] traits - don more than 3 pojos, got IllegalArgumentException
I tried to repdroduce the issue, but I couldn't get the same error.. could you provide a test case?

Re: [rules-users] traits - don more than 3 pojos, got IllegalArgumentException
Hi Michal, I double checked and indeed the problem happens... it puzzles me, seems a problem with the ASM-generated code. If you could open a JIRA, I'll try to debug it as soon as I get a moment. The problem happens only with legacy classes declared @Traitable, so the immediate workaround is to use DRL-declared beans Thanks Davide -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-traits-don-more-than-3-pojos-got-IllegalArgumentException-tp3788670p3800419.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] traits - don more than 3 pojos, got IllegalArgumentException
This is odd... I tried to reproduce your issue but I didn't get any exception. Trying to react to any NiceMessage also produces the expected results... Now, I see that you do Message.setMessage(), so I assume that Message and NiceMessage are classes defined outside the DRL.. Could you send them so that I can take a look?

Re: [rules-users] traits - don more than 3 pojos, got IllegalArgumentException
Hi Davide,
thanks for looking into this.
Message is a class defined outside of the DRL, its source is below.
NiceMessage is defined only inside the DRL.
public class Message {
public static final int HELLO = 0;
public static final int GOODBYE = 1;
private String message;
private int status;
public String getMessage() {
return this.message;
}
public void setMessage(String message) {
this.message = message;
}
public int getStatus() {
return this.status;
}
public void setStatus(int status) {
this.status = status;
}
}
Best regards,
Michal

[rules-users] traits - don more than 3 pojos, got IllegalArgumentException
Hi all, I came across this issue when trying out 'traits' with POJOs (not declared types). An IllegalArgumentException is being thrown when I apply the third 'don'. Here is how to reproduce: as the POJO I am using the Message class that comes with the project created by the Eclipse plugin. now the rule file: declare Message @Traitable end declare NiceMessage @format(trait) end rule load when then Message message = new Message(); message.setMessage(Hello World); insert(message); don(message, NiceMessage.class); Message unreadMessage = new Message(); unreadMessage.setMessage(unread); insert(unreadMessage); don(unreadMessage, NiceMessage.class); Message oldMessage = new Message(); oldMessage.setMessage(old); insert(oldMessage); System.out.println(don + oldMessage); don(oldMessage, NiceMessage.class); //*--- exception happens here* System.out.println(wont reach this point); end When I run this and rule 'load' fires the third 'don' will throw the following exception: Exception executing consequence for rule load in com.mycompany.app: java.lang.IllegalArgumentException: argument type mismatch at org.drools.runtime.rule.impl.DefaultConsequenceExceptionHandler.handleException(DefaultConsequenceExceptionHandler.java:39) at org.drools.common.DefaultAgenda.fireActivation(DefaultAgenda.java:1101) at org.drools.common.DefaultAgenda.fireNextItem(DefaultAgenda.java:1029) at org.drools.common.DefaultAgenda.fireAllRules(DefaultAgenda.java:1251) at org.drools.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:709) at org.drools.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:673) at org.drools.impl.StatefulKnowledgeSessionImpl.fireAllRules(StatefulKnowledgeSessionImpl.java:221) at com.mycompany.app.DroolsTest.main(DroolsTest.java:44) Caused by: java.lang.IllegalArgumentException: argument type mismatch at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:532) at org.drools.factmodel.traits.TraitFactory.getProxy(TraitFactory.java:92) at org.drools.base.DefaultKnowledgeHelper.don(DefaultKnowledgeHelper.java:502) at org.drools.base.DefaultKnowledgeHelper.don(DefaultKnowledgeHelper.java:522) at com.mycompany.app.Rule_load_86ecf966a4c14d8486844cfae2e1e0d8.defaultConsequence(Rule_load_86ecf966a4c14d8486844cfae2e1e0d8.java:21) at com.mycompany.app.Rule_load_86ecf966a4c14d8486844cfae2e1e0d8DefaultConsequenceInvokerGenerated.evaluate(Unknown Source) at com.mycompany.app.Rule_load_86ecf966a4c14d8486844cfae2e1e0d8DefaultConsequenceInvoker.evaluate(Unknown Source) at org.drools.common.DefaultAgenda.fireActivation(DefaultAgenda.java:1091) ... 6 more Am I doing something wrong or is this a bug.

Sorry, the way to declare traits has been changed in one of the latest versions... the code is still very experimental and subject to changes.
