----- evaluation ---------------
The problem is twofold:
1. The new total decorators don't implement interfaces expected
by the excel and pdf exporters, namely,
org.displaytag.decorator.hssf.DecoratesHssf for excel and
org.displaytag.render.ItextDecorator
Implementing these interfaces should be required only if the
decorator needs to do hssf or itext work. In general, they
should become optional.
As a workaround, you'll need to extend the total decorator you're using,
(org.displaytag.decorator.MultilevelTotalTableDecorator or
TotalTableDecorator)
so that they implement these interfaces.
2. You'll also need to explicitly configure you're new excel and pdf
decorators, like so.
<display:setProperty name="export.excel.decorator"
value="name.of.your.excel.decorator" />
<display:setProperty name="export.pdf.decorator"
value="name.of.your.pdf.decorator" />
> TableDecorator created with 1.0 doesn't work properly with 1.1. Properties
> defined only it decorator
