[rules-users] Rules "if one of element of this array has ... "

[Maxime Terrettaz]

Hi, 

I have OUL_R21 facts which have a array of OUL_R21_ORDER_OBSERVATION
objects.
OUL_R21_ORDER_OBSERVATION object has a array of OUL_R21_OBSERVATION.
OUL_R21_OBSERVATION object has a array of OUL_R21_OBSERVATION_RESULT.
And OUL_R21_OBSERVATION_RESULT has a OBX child.
I want to add the number one in my global list if one of all OBX has
abnormalFlags.value in ( 'HH', 'LL', 'AA', 'H', 'L', 'A' )

if
(OUL_21.ORDER_OBSERVATIONS[*].OBSERVATIONS[*].OBSERVATION_RESULTS[*].OBX.abnormalFlags.value
in ( 'HH', 'LL', 'AA', 'H', 'L', 'A' )) list.add(1);

Here is the rule in tring to create...

package com.xwave.drools 
import com.xwave.hapi.hl7v2.model.v24.message.OUL_R21
import com.xwave.hapi.hl7v2.model.v24.group.OUL_R21_ORDER_OBSERVATION
import com.xwave.hapi.hl7v2.model.v24.group.OUL_R21_OBSERVATION
import com.xwave.hapi.hl7v2.model.v24.group.OUL_R21_OBSERVATION_RESULT
import java.util.ArrayList
import ca.uhn.hl7v2.model.v24.segment.OBX
global java.util.List list

/* Pour le chainage de tableau, il est obligatoire de le faire étape après
étape */
rule "Get All OBX"
dialect "mvel"
when
	$labMessage : OUL_R21()		
	$orderObservation : OUL_R21_ORDER_OBSERVATION() from
$labMessage.ORDER_OBSERVATIONS
        $observation : OUL_R21_OBSERVATION() from
$orderObservation.OBSERVATIONS 
        $observationResult : OUL_R21_OBSERVATION_RESULT() from
$observation.OBSERVATION_RESULTS
        $obx : OBX() from $observationResult.OBX
    then     
    	insert($obx);
end

rule "Abnormals"
dialect "mvel"
when
		$result : ArrayList(size > 0) from collect(OBX(abnormalFlags.value in (
'HH', 'LL', 'AA', 'H', 'L', 'A' )))
    then 
    	System.out.println("Abnormal result : " + $result);
    	list.add(1);
end

Could you please tell me the solution.
