[rules-users] Rules "if one of element of this array has ... "
Hi,
I need to create a rule to verify is the value of a property.
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_OBSERVATIONobject 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' )
OUL_21.ORDER_OBSERVATIONS[].OBSERVATIONS[].OBSERVATION_RESULTS[].OBX.abnormalFlags.value
in ( 'HH', 'LL', 'AA', 'H', 'L', 'A' )
Here is the rule in tring to create...
<code>

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"
lock-on-active
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 "Anormaux"
dialect "mvel"
when
$result : ArrayList(size > 0) from collect(OBX(abnormalFlags.value in (
'HH', 'LL', 'AA', 'H', 'L', 'A' )))
then
System.out.println("Résultats anormaux : " + $result);
list.add(1);
end
