Firstly, you do actually need to do as it says. You are being asked only for
a subset of the rows, not all of the rows, and you should return only the
rows that were requested.

The format of the returned data is defined. I suspect that your server is
returning data in a format other than what is expected. Look at the
documentation or the implementation of _onRowDataLoaded() to see exactly
what format is required. Then use Firebug or equivalent to look at the data
to ensure you're matching that format.
Hope that helps.
