[rules-users] stackOverFlowError when serializing a RuleBase

Hi, I get a similar error to pedrof's: java.lang.StackOverflowError at java.io.ObjectStreamClass$FieldReflector.getPrimFieldValues(ObjectStream Class.java:1907) at java.io.ObjectStreamClass.getPrimFieldValues(ObjectStreamClass.java:1184 ) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:14 94) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1474) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1 392) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1150) ... Ad infinitum I'm wondering if anyone else has got this error? All I'm doing is serializing the rule base: ByteArrayOutputStream out = new ByteArrayOutputStream(); ObjectOutputStream oOut = new ObjectOutputStream(out); oOut.writeObject(ruleBase); oOut.flush(); oOut.close(); Any ideas? Maybe it's some kind of circular reference problem... Cheers, Rene
