[rules-users] Error with MVEL2 Using Smooks 1.4 and Drools 5.2

Hi guys,

I am newbie in this kind of things, but I am facing some difficults to use
Smooks 1.4 an d Drools 5.2. It seams that MVEL2 present in the drools 5.2
distribution is not compatible with Smooks 1.4.
Did anybody have similar problems ?

If a have a separate project, which uses Smooks 1.4, my program is able to
read a CSV file and convert it to Java Bean List, in fact, a Java List.
However, If I use the same structure to read information from a CSV file and
insert hem into a Drools Rule Engine, I got the error right below: Does
anybody know how I can fix that ?

This is my smooks configuration file:
<?xml version="1.0"?>
<smooks-resource-list xmlns="http://www.milyn.org/xsd/smooks-1.1.xsd"
    xmlns:csv="http://www.milyn.org/xsd/smooks/csv-1.3.xsd"

        <param name="stream.filter.type">SAX</param>
    </params>

    <csv:reader

        <jb:bean beanId="transformedProps" class="java.util.HashMap"
createOnElement="csv-record">
            <jb:value property="@alarmName" data="csv-record/alarmName" />

    <jb:bean beanId="ListOfalarms" class="java.util.ArrayList"
createOnElement="csv-set">
        <jb:wiring beanIdRef="alarms" />
    </jb:bean>


    <jb:bean beanId="alarms"
class="br.com.lavoisierfarias.correlator.model.Alarm"
createOnElement="csv-record">
        <jb:value property="alarmName" data="csv-record/alarmName"/>
        <jb:value property="Ne" data="csv-record/ne"/>

        <jb:value property="subrack" data="csv-record/subrack"/>
        <jb:wiring property="alarm" beanIdRef="Alarm" />
        <jb:expression property="startDate" execOnElement="csv-record">
        startDate = transformedProps["startDate"] + " " +
transformedProps["startTime"];
        new java.text.SimpleDateFormat("dd/MM/yyyy
HH:mm:ss").parse(startDate)
        </jb:expression>
       <jb:value property="endDate" decoder="Date"
data="csv-record/endDate">
            <jb:decodeParam name="format">dd/MM/yyyy</jb:decodeParam>
        </jb:value>
        <jb:value property="endTime" decoder="Date"
data="csv-record/endTime">
            <jb:decodeParam name="format">HH:mm:ss</jb:decodeParam>
        </jb:value>

    </jb:bean>

</smooks-resource-list>

This is an example of the file that has to bew parsed:
*
alarmName,Ne,board,serialNumber,slot,subrack,startDate,startTime,endDate,endTime
