Store events in differents tables/ AVG function error

Question

HI,
I have a very newbie question that i can't resolve.
I want to store events in a database, so far so good, but if i define the events on context file like this:
<wlevs:event-type-repository>
<wlevs:event-type type-name="Averages">
<wlevs:properties>
<wlevs:property name="average_Generator1_ActivePower" type="float"/>
<wlevs:property name="sum_Generator2_ActivePower" type="int"/>
<wlevs:property name="max_Substation_Active_Power" type="int"/>
<wlevs:property name="number_events" type="int"/>
</wlevs:properties>
</wlevs:event-type>
<wlevs:event-type type-name="WindEvent">
<wlevs:properties>
<wlevs:property name="generator1_ActivePower" type="int"/>
<wlevs:property name="generator2_ActivePower" type="int"/>
<wlevs:property name="substation_Active_Power" type="int"/>
</wlevs:properties>
</wlevs:event-type>
</wlevs:event-type-repository>
They will be saved in the same table, TupleValues table.
I try to workaround this situation by defining one of the events as a class and in this case the Oracle CEP create a different table to store this events. But, with this configuration, I have an error on the processor node, most exactly, in the avg function that use a property of the class created. Below there is the context file, the java class and the query in the processor
#Java class
public class WindEvent {
     private Integer Generator1_ActivePower;
     private Integer Generator1_AverageExpectedEnergy;
     private Integer Generator2_ActivePower;
     private Integer Generator2_AverageExpectedEnergy;
     private Integer Substation_Active_Power;
     private Integer Substation_AverageExpectedEnergy;
#context file
<wlevs:event-type-repository>
<wlevs:event-type type-name="WindEvent">
<wlevs:class>oracle.cep.demo.events.WindEvent</wlevs:class>
</wlevs:event-type>
</wlevs:event-type-repository>
     <wlevs:adapter id="adapter" provider="csvgen">
          <wlevs:listener ref="channel" />
          <wlevs:instance-property name="port" value="9001" />
          <wlevs:instance-property name="eventTypeName" value="WindEvent" />
          <wlevs:instance-property name="eventPropertyNames"
value="generator1_ActivePower,generator1_AverageExpectedEnergy,generator2_ActivePower,generator2_AverageExpectedEnergy,substation_Active_Power,substation_AverageExpectedEnergy"/>
     </wlevs:adapter>
     <wlevs:channel id="channel" event-type="WindEvent">
          <wlevs:listener ref="processor" />
     </wlevs:channel>
     <wlevs:processor id="processor">
     </wlevs:processor>
#query
<processor>
<name>processor</name>
<rules>
<query id="ExampleQuery">
<![CDATA[select  avg(substation_Active_Power) as max_Substation_Active_Power, count(*) as number_events from channel [range 60]]]>
</query>
</rules>
</processor>
If somebody could help in the two questions i will be really grateful
