Primefaces data exporter from data table with dynamic columns

问题

Has anyone used primefaces data exporter component successfully with primefaces datatable with dynamic columns?

In my case, it generates the excel file but it is empty.

But if I keep everything same and just normal datatable instead of datatable with dynamic columns, the generated excel file is not empty.

I am trying to see if somebody has done this.

<p:dataExporter />
and
<p:dataTable /> //(with dynamic columns)

It works fine if I don't use the dynamic columns.

I am using PrimeFaces 2.2.1, JSF 2.0, poi-3.2-FINAL.jar.

Sorry but this is not currently supported for the dataExporter component.

This is coming straight from Cagatay Civici, lead developer on the Primefaces project.
