XML Publisher error while viewing a report

Question

I get the following error while viewing a report I have just written using a data template:
The report cannot be rendered because of an error, please contact the administrator.
I am using XML Publisher 562 Enterprise.
The Data template I have loaded is as follows:
<dataTemplate name="FLEETMASTERS" description="Fleet Masters Listing">
     <dataQuery>
          <sqlStatement name="Q1">
               <![CDATA[SELECT fm.fms_id, fm.reg_no, fm.vsn, fm.vin
                 FROM fleet_masters fm
                 WHERE rownum <= 100]]>
          </sqlStatement>
     </dataQuery>
</dataTemplate>
The rtf template loaded is simply
Fms Id     Reg No     Vin
F FMS_ID REG_NO VIN E
If I use a Data Model using a SQL Query and type in above select statement, it works fine. The moment I use a Data Template I get the error mentioned above.
A dump of the error in the log is

Okay some more information:
If I change the data template to this
<dataTemplate name="FLEETMASTERS" description="Fleet Masters Listing">
     <dataQuery>
          <sqlStatement name="Q1">
               <![CDATA[SELECT fms.fms_id FMS_ID, fm.reg_no REG_NO , fm.vin VIN
                 FROM fleet_masters fm
                 WHERE fm.fms_id BETWEEN 55531 and 55620 ]]>
          </sqlStatement>
     </dataQuery>
</dataTemplate>
I only get the titles being printed but no errors i.e the select does not seem to retrieve data from the database(85 records in database). If I remove the where clause I get the same titles as per the template with no data(49089 records in Database).
Layout of template
Fms Id Reg No Vin
Now it begs the question, is XML Publisher finicky about the syntaxes you can use inside the "sqlStatement" clause?
I have to say that this is really frustrating as I have had no successes using Data Templates
