Problems with <p:dataexporter>

[Devos]

Hi,

I'm trying to use the most simple form:

Code: Select all

<h:commandLink value="PDF">
  <p:dataExporter type="pdf" target="datatable" fileName="cars"/>
</h:commandLink>

with a datatable that generates perfectly and has the following outline:

Code: Select all

<p:dataTable id="datatable"
                    var="rio"
                    value="#{holidaybean.holidayRequestOperationList}"
                    paginator="true"
                    rows="10"
                    selectionMode="single">

I get the following error:

Code: Select all

HTTP Status 500 -

type Exception report

message

exception

javax.servlet.ServletException

root cause

java.lang.NullPointerException

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.12 logs.

Does anybody know what I'm doing wrong?
