I modifed the DataExporter demo code so that it populates the DataTable when a "Submit" commandButton is clicked. The data is not exported, only the headers.
Could anyone tell me if I am not updating the correct ui component or if it is a bug?
The submit button code:
Code: Select all
<p:commandButton value="Submit" process="@form"
actionListener="#{tableBean.submit}"
update="testFormId,tbl" />
xhtml:
Code: Select all
