Is the example working for you (non-icefaces)?
There is an example for seam-pdf and icefaces using jsf-delegation (not sure if you had tried it--should also work for the export to excel module for seam). Also, there is an
component for the export of data tables to csv or excel....just wondering if you had tried it.
Otherwise, you could always open a jira with a basic sample for request concerning a specific issue
