[jboss-jira] [JBoss JIRA] (DROOLS-570) Rule inheritance fails when using or pattern binding

[Davide Sottara (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-570?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12989666#comment-12989666 ] 

Davide Sottara commented on DROOLS-570:
---------------------------------------

Confirmed.. 
the problem happens during the generation of the second rule's consequence.
See org.drools.core.rule.builder.dialect.asm.ConsequenceGenerator#235: the method "getQueueIndex" has actually been renamed "getIndex".

Unfortunately 6.1 has just been released, so you will have to use a SNAPSHOT or apply the fix yourself and recompile the code. 
A workaround, use mvel rather than java in the second rule adding the attribute:
{code}
dialect "mvel"
{code}

Thanks for reporting this
Davide

> I've found a certain combination of rules (when using inheritance) that causes drools to throw the following exception: http://pastebin.com/xxq5ZtAC 
> The rules that cause this exception to occur can be found here: http://pastebin.com/wM6rWY8L
> I've simplified my original rules down to the lowest level of detail that still throws the exception. The exception is no longer thrown if I: 
> 1. Don't use rule inheritance 
> 2. Don't have an or statement 
> 3. Don't reference an LHS defined variable in the RHS of ruleB
