export CLOB

Using version 3.1-p20140602 of smartGWT.

I have a datasource which contains a field which maps to a CLOB column.

When calling fetch on this datasource the data is correctly displayed on the client, but in the case of an export, the data is not read and instead the exported file displays for that field the JAVA object.toString() result, i.e. oracle.jdbc.driver.OracleClobReader@xxxxxx

Is this dual behaviour expected?

Thanks.
