Prepend not working

[Michael Schall]

I have the following code and does not work.  Is this a bug or am I
not understanding how the prepend should work?  I get a "sql error
near tp_Calls".  The prepends aren't adding in the "and" to the
resultant sql string.

<dynamic prepend="WHERE">
        <![CDATA[
          OffHookDt <= #EndDate# AND
          OffHookDt >= #StartDate#
        ]]>
        <isNotNull property="LocationCode">
                <isNotEqual prepend="and" property="LocationCode" 
compareValue="%">
                        tp_Calls.LocationCd = #LocationCode#
                </isNotEqual>
        </isNotNull>
        <isNotEqual prepend="and" property="RateType" compareValue="-1">
                RateType = #RateType#
        </isNotEqual>
        <isEqual prepend="and" property="PrivateAllowed" compareValue="0">
                tp_Calls.Hidden = 0
        </isEqual>
</dynamic>

If I change it to the following everything works great.

<dynamic prepend="WHERE">
        <![CDATA[
          OffHookDt <= #EndDate# AND
          OffHookDt >= #StartDate#
        ]]>
        <isNotNull  property="LocationCode">
                <isNotEqual property="LocationCode" compareValue="%">
                        and tp_Calls.LocationCd = #LocationCode#
                </isNotEqual>
        </isNotNull>
        <isNotEqual property="RateType" compareValue="-1">
                and RateType = #RateType#
        </isNotEqual>
        <isEqual property="PrivateAllowed" compareValue="0">
                and tp_Calls.Hidden = 0
        </isEqual>
</dynamic>
