[rules-users] Accessing items in a list

[mkhan]

Hi,
I am  new to doorls so please can you help me.
I am trying to access an ietm from a list in a rule like ...

$data: List(this != null, size > 9) from accumulate(
	$obj1 : FwVehicle(
		notchCodingWire1 != null, 
		lineVoltage != null
	)
	over window:time(10s)
	from entry-point "DataStream",
	collectList($obj1)
)

$first : $data.get(0)

but i get an error ...
[ERR 102] Line 164:19 mismatched input '0' expecting ')' in rule "test1" in
pattern $data.get

Does anyone have any ideas what I am doing wrong please?
