Thanks for the continued help... but

ArrayList<MessageAsEvent> a=new ArrayList<MessageAsEvent>();
MessageAsEvent a1=new MessageAsEvent(); a1.setSerial("serial123");
a1.setUuid("mesC:7"); a1.setId(888); a.add(a1);
MessageAsEvent a2=new MessageAsEvent(); a2.setSerial("serial123");
a2.setUuid("mesC:7"); a2.setId(889);a.add(a2);
ksession.setGlobal("hibernateSession", hibernateSession);
ksession.setGlobal("data", a);
----
global java.util.ArrayList data;
rule "Repeating as signature"
when
$m : MessageAsEvent(uuid=="mesC:7")
$others : MessageAsEvent(uuid=="mesC:7", id!=$m.id)
from data
then
System.out.println("++++++++++++Gathering in signatures m="+$m+"
data="+$others);
insert($others);
end
----
and I still get;
Audit:-
<org.drools.audit.event.ActivationLogEvent>
<type>4</type>
<activationId>Repeating as signature [15, 14]</activationId>
<rule>Repeating as signature</rule>
<declarations>$others=MessageAsEvent:[888] uuid=mesC:7 serial=serial123
count=0(15); $m=MessageAsEvent:[254] uuid=mesC:7 serial=serial123
count=7(14)</declarations>
<ruleFlowGroup>Signature</ruleFlowGroup>
</org.drools.audit.event.ActivationLogEvent>

<ruleFlowGroup>Signature</ruleFlowGroup>
</org.drools.audit.event.ActivationLogEvent>
Console:-

with data=null being shown
