If you must use 5.2 you can try using "from" to access the PhoneTypecode, rather than (I assume) an expression:-

$p : Phone( )
$tc : PhoneTypecode( ... ) from $p.phoneTypeCode

etc.

Unfortunately this appears to be a problem with 5.2.

There is an additional space in "phoneTypeCode .tc" which should read "phoneTypecode.tc".

I have confirmed this does not happen in 5.4.CR1 (and possibly earlier):-

1.|rule "r2"
2. |    dialect "mvel"
3.|     when
4.|        Phone( $ac : areaCode, $tc : ptc.tc)
5.|        Phone( areaCode == $ac , ptc.tc != $tc )
6. |    then
7.|end

2. guvnor version is 5.2 final

3. actual class:

public class Phone {

   @XmlElement(name = "PhoneKey")
   protected String phoneKey;
   @XmlElement(name = "PhoneTypeCode")
   protected PhoneTypeCode phoneTypeCode;
   @XmlElement(name = "AreaCode")
   protected String areaCode;
   @XmlElement(name = "DialNumber")
   protected String dialNumber;
   @XmlElement(name = "Ext")
   protected String ext;
   .
   .
   .
}


public class PhoneTypeCode {

   @XmlValue
   protected String value;
   @XmlAttribute
   protected String tc;

...}
