Hi,
Please use ExpressionTableColumn rather than
SimpleTableColumn in your code -- that will allow you
to extract the value you want in that column using
OGNL. SimpleTableColumn does not do that unless you
override it or set an evaluator.
Also, what was wrong with the source/columns approach?
It should be perfect for the task...
