I am able to reproduce it (test_common.drl line 28), could you please confirm
an upgrade will fix the issue?

Many thanks!

Re: [rules-users] 'last modified' and 'created by' attributes for a asset showing wrong userid in Guvnor 5.4.0.final

[vadlam]

we noticed the behavior that the userid of the user who logs in first into
Guvnor after it is started up is the one that shows up for all subsequent
updates to assets irrespective of who modifies the asset.


In the RepositoryAssetService class in guvnor-webapp-core module, the
getCurrentUserName() always shows the same userid ( whoever logs in first )


log.info( "USER:" + getCurrentUserName() + " CHECKING IN asset: [" +
asset.getName() + "] UUID: [" + asset.getUuid() + "] " );

Re: [rules-users] java.lang.ClassCastException: [Lorg.drools.rule.Package; cannot be cast to org.drools.rule.Package

[Mark Proctor]

That's assuming you have done as geoffrey instructed and use the correct 
classes. Lots of examples here in this unit test, as to which classes to use:
http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/releases/org.drools/drools-compiler/5.5.0.Final/org/drools/agent/KnowledgeAgentTest.java/

So first make sure you are using the correct classes and apis, as per above. 
Then do as per below, checking your client and server class paths and 
rebuilding packages on the server.

Re: [rules-users] java.lang.ClassCastException: [Lorg.drools.rule.Package; cannot be cast to org.drools.rule.Package

[Mark Proctor]

Your's is a different issue. 

You either have an incorrect class path, with mixed versions. Or your client 
and your server are using different versions. Or you didn't tell Guvnor to 
recompile all it's packages, when you changed jar versions.

Also your try/catch would result in no actual consequence happening - which 
would be pointless.

Re: [rules-users] java.lang.ClassCastException: [Lorg.drools.rule.Package; cannot be cast to org.drools.rule.Package

[Ganesh]

Hi David,


Thanks for response,
Exacts exception is "java.lang.ClassCastException:
[Lorg.drools.rule.Package; cannot be cast to org.drools.rule.Package "


And I am not handing exception in any java code ..
I am just handling it in rule part.

ex.

dialect "java"
no-loop
ruleflow-group "Apply Buy Discount"

when
/*removed*/
then

try{


System.out.println("==");
System.out.println("Apply Buy Discount");
System.out.println($discountPercent);
System.out.println($advAdditional);
System.out.println("==");
$lql.setEndUserUnitPrice(applyDiscount($lql.getEndUserUnitPrice(),$discountPercent+$advAdditional));

$lql.setTotalCost(applyDiscount($lql.getTotalCost(),$discountPercent));
//  update($lql);

}
catch(Exception e)
{

System.out.println(e.toString());

}

Let me know if any issue.

Re: [rules-users] Change Notification doesn't work with eval(true) in one of the rules

[Davide Sottara]

Replacing eval( true) with Boolean( this == Boolean.TRUE ) results in a
different network configuration:
the former requires an EvalNode, the latter a JoinNode.
A few issues with EvalNode dynamic additions/removals have been found
and fixed over time,
including one that was found last week. Please do check with later versions.
Davide

p.s. there may be more robust ways to control which rules are enabled or
not at a given moment.

Re: [rules-users] java.lang.ClassCastException: [Lorg.drools.rule.Package; cannot be cast to org.drools.rule.Package

[Davide Sottara]

Could you post the exact exception, as well as the code you are using to
set up the knowledgeagent?
Adding try/catch is quite likely to break your system, since your
knowledge base won't be loaded
correctly anyway.

Re: [rules-users] Change Notification doesn't work with eval(true) in one of the rules

[Wolfgang Laun]

Try some later version. 5.2.0 was the version after a major rework,
and your problem might disappear using 5.[345].0 etc.

If this doesn't help, consider posting the rule, after systematically
obfuscating app-specific names *without removing anything*.

Re: [rules-users] Change Notification doesn't work with eval(true) in one of the rules

[Sammi]

Version is 5.2.0.Final I am using.

I am not able to reproduce the issue when I wrote a small test to simulate
the problem. But really by changing the line from "eval(...)" to
"Boolean(this == Boolean.TRUE)" then the issue was gone. 

The problematic programs are too complicated to be shown here, and it's not
appropriate as there are business logic in it.

What might be the issue causing this? if anyone could shed some light It
would be greatly appreciated...
