Last field not shown in MONI if its empty during content conversion-urgent

Hi All,

I have my input structure like

<RECORDSET>

<EMPLOYEE>

<FIRSTNAME>

<LASTNAME>

<PHONENUMBER>

</EMPLOYEE>

</RECORDSET>

I have given my sender Conversion parameters like

Employee.fieldSeparator=*

Employee.endSeparator='nl'

Employee.fieldNames=FIRSTNAME,LASTNAME,PHONENUMBER

It is working fine.But if the value is empty for any of the field it is showing up with empty tag in MONI but for the Last field i.e.,PHONENUMBER if the value is empty the tag is not being shown in MONI. Please help me in this issue.It is very urgent.
