How can I make Coldfusion Reactor ignore some columns in a table - orm

Question

I'm using Coldfusion 10 + Reactor in project. I add a new TIMESTAMP field which will auto updated to CURRENT_TIMESTAMP. It works when this new field is not included into Reactor objects, e.g. Dao, To, Record. but it will be failed once regenerate ColdFusion objects.
so how can I ignore the new field in reactor?
Here are the related code
<object name="Object">
<hasOne name="XXXX">
<relate from="KeyUUID" to="KeyUUID"/>
</hasOne>
...
</object>
After I regenerated ColdFusion objects, the create/update method in ObjectDao.cfc will include my new field. The ObjectDao.cfc is regenerated by Reactor according to my database table. I want this new field excluded from Reactor objects, e.g. Dao, To, Record.
<cfquery name="qCreate" datasource="#_getConfig().getDsn()#" username="#_getConfig().getUsername()#" password="#_getConfig().getPassword()#">
INSERT INTO #Convention.FormatObjectName(getObjectMetadata())#
(
...
#Convention.formatInsertFieldName('newField', 'Object')#
) VALUES (
...
<cfqueryparam cfsqltype="cf_sql_timestamp"
value="#arguments.to.newField#"
null="#Iif(NOT Len(arguments.to.lastModifiedDBTime), DE(true), DE(false))#"
/>
)
...
</cfquery>

We implement this by update ObjectDao.cfc for now.
<cffunction name="readFields" access="private" hint="I populate the table with fields." output="false" returntype="void">
...
<cfloop query="qFields">
<cfset blnProcess = true />
<cfif structKeyExists(stcFieldsToSkip,arguments.Object.getName())>
<cfif qFields.FIELD EQ stcFieldsToSkip[arguments.Object.getName()]>
<cfset blnProcess = false />
</cfif>
</cfif>
<cfif blnProcess>

mod by SPJ: in MySql 4 tinytext, text, mediumtext and longtext don't report their maxlength value, so we
have to set it by hand. The field lengths were obtained from http://www.cs.wcupa.edu/~rkline/mysqlEZinfo/data_types.html#Storage_requirements

<cfswitch expression="#qFields.TYPE#">
...
</cfswitch>
<!--- end mod by SPJ --->
<!--- create the field --->
...
<!--- add the field to the table --->
<cfset arguments.Object.addField(Field) />
</cfif>
</cfloop>
</cffunction>
