[rules-users] Still getting an EvalConditionNode ClassCastException

We're only seeing it on a customer customization so I'm a little hesitant to put out the SNAPSHOT to them, I will try though. Do you know what the plan is for releasing 5.1.0 or at least a 5.1.0.M3?
At the very least I'll try to make a test case I can get to repeat in dev.

Paul,
Did you tried trunk?
The source of this problem was not in the EvalNode class itself (that is why you mention the code is still there), but on the re-use of node ids, that determine the position of the node memory in the memory array. I fixed this in trunk a few weeks ago. Give it a try and let me know if you still see any problem, but I think it is everything fine now.

Thanks,

We're still getting a class cast exception for beta and eval memory (exception below). It is a different location and the opposite direction of the exception cast from JBRULES-1719.
The rule we ran was:
/**
* Load the smgl transform
*/
rule "Load Transform"
when
$fact : ParametersFact(
doc != "dmodule",
$xml : xml != null,
noopResponse == true,
eval(XPathUtil.selectElement($xml,"/*/transformLog//transform[name='s1000dv3']")==null),
flags['loadedS1000Dv3']!=true,
eval(XPathUtil.selectElement($xml,"/*/transformLog//transform[name='detect']/results[result='text/xml']")!=null)
)
$importUtil : RuleImportUtil()
$model : EditionsRulesJobRunner(stop==false,interrupt==false)
then
Vector<String> libraries = new Vector<String>();
libraries.add("lib");
String documentType = "dmodule";
String fragmentType = "dmodule";
$importUtil.importRules(kcontext,"transformCmd",documentType,fragmentType,libraries);
$fact.getFlags().put("loadedS1000Dv3",true);
end
The thing of consequence here is the importRules call which modifies the kcontext and acts as a dynamic include (e.g. it imports new rules).
The exception received is:

Point of speculation:
When looking at the latest code on trunk I would believe this is not fixed as the line pointed to here has not changed (the place where this line exists has changed but not the code see fisheye at http://fisheye.jboss.org/browse/JBossRules/trunk/drools-core/src/main/java/org/drools/reteoo/EvalConditionNode.java?r1=23650&r2=34068&u=20 and where the lefthand side was 199 for 5.0.1 it is still the same code in the latest svn revision (now line 229).
