Committed change to the trunk at revision 31346. The 'exporter' method signature was modified to avoid having to pass in every configuration parameter when invoking the exporter. Instead the ace:dataExporter component itself will be passed in, and the Exporter instance will retrieve whatever information it needs from the component. This is to facilitate the use of custom exporters in the future.

Committed improvement at revision 30649 in the trunk.
Note: since the ace:dataExporter component has always worked by creating a new instance of a specific exporter type, the best practice for a custom exporter is to return a new instance of the exporter in the getter method, e.g.:
public Object getCustomExporter()
{ return new MyExporter(); }Since, this getter is called in the Invoke Application phase, the exporter instance can pass any other application data in the constructor of the custom exporter, e.g.:
public Object getCustomExporter()
{ return new MyExporter(selectedItems); }
