cannot get anything from dataimporter.request on updating index

Question

I'm quite new in SOLR, I have a question regarding the request for data importer.

In my data-config.xml, i have something like this

<entity name="content" pk="id" query="SELECT * FROM tableX"
    deltaQuery="SELECT max(id) AS id from ${dataimporter.request.dataView}"
    deltaImportQuery="SELECT * FROM tableX WHERE ${dataimporter.delta.id} &lt; id">
....
</entity>

However, everytime I execute delta-import (/dataimport?command=delta-import), it always gives me exception like this:

Caused by: java.lang.RuntimeException:
    org.apache.solr.handler.dataimport.DataImportHandlerException: 
Unable to execute query: 
    SELECT max(id) AS id FROM  Processing Document # 1

I believe this error exists because the system didn't recognize ${dataimporter.request.dataView}, but I don't know how to make that recognized?
