exportable=false is ignored

[Damiano Esposito]

When using DataTables users usually have an additional column containing a button to trigger actions on a particular entry / row.

Something like:

<p:column toggleable="false" exportable="false">
  <p:menuButton value="Options">
  ...
  </p:menuButton>
</p:column>

When setting exportable to false the column still gets exported which results in a CSV containing entries like the following:

..., "org.primefaces.component.menubutton.MenuButton@3695980b"
..., "org.primefaces.component.menubutton.MenuButton@3695980b"
