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).
