Facing problem with in

[bhavneet91]

We tried in following rule.

dialect "mvel"

import com.****.model.DateObject;

import com.*******.model.RuleVariables;

import function com.***********.model.test.print;

import com.*********.sophia.model.test;

import com.********.model.AttributeValue;

import java.util.List;

import java.util.*;

import java.util.Map;

import com.********.model.CardOrderingRule_EXP;

import java.lang.System;

import java.util.HashMap;

rule "Rule_11"

lock-on-active

agenda-group "Experiment1+CARD_Sequence_1"

when

  $dateObject : DateObject($startTime : startTime, $endTime : endTime, $a : waitBlockResponse)

  Boolean($value : booleanValue) from (false)

  $r : RuleVariables(( !((attributes.get("APSPERSONA")) != null && (((String)(((AttributeValue)(attributes.get("APSPERSONA"))).getValue())) in('DESIGNER', 'PHOTOGRAPHER')))))

  RuleVariables($subscriptions : subscriptions)

   $listTest : List()

    from collect

    (

       Map(this["ENTITLE"] != null)

      from $subscriptions.values

    )

then

  print("11")

  System.out.println($value)

  System.out.println("ListSize : " +$listTest.size());

  System.out.println(($a[2]))

  kcontext.getKnowledgeRuntime().getAgenda().getAgendaGroup('Experiment1+CARD_Sequence_17').setFocus()

end

Following is the error we are getting.

Message [id=1, level=ERROR, path=com*********template/11.drl, line=24, column=0

   text=Unable to Analyse Expression ( !((attributes.get("APSPERSONA")) != null && (((String)(((AttributeValue)(attributes.get("APSPERSONA"))).getValue())) in("DESIGNER", "PHOTOGRAPHER")))):

[Error: unable to resolve method using strict-mode: com.*******.model.RuleVariables.in(java.lang.String, java.lang.String)]

[Near : {... NA"))).getValue())) in("DESIGNER", "PHOTOGRAPHER") ....}]

Why can't it go to mvel 'in'?

Can please some one help
