NSKeyValueCodingAdditions.Utility.valueForKeyPath(lpi,
"displayGroup.dataSource");
Or you could use ERD2WUtilities.enclosingPageOfClass(sender,
ERDListPageInterface.class) so you can just call displayGroup()
directly.

Hi Ramsey!
Okay, so how do I get the EODataSource from the resulting
ListPageInterface?

ERD2WUtilities.parentListPage(sender) should give you the next list
page up for the sender even if the sender is nested.

Hi all,
I'm using the instructions here: http://wiki.objectstyle.org/confluence/display/WO/D2W+Flow+Control
to add a function to my D2W listing page that will create and
Excel file of the objects listed. It works great, but I'm not
comfortable with how I'm getting the EODataSource from the
existing page. Here's how I'm doing it now:
// "Export To Excel"
public WOActionResults exportToExcel(WOComponent sender) {
setSender(sender);
ListPageInterface lpi = (ListPageInterface) D2W.factory()
.pageForConfigurationNamed
("ListExcelCCCommunicationIdentity",
sender
().session());
lpi.setDataSource((EODataSource) sender().parent()
.valueForBinding
("dataSource"));
lpi.setNextPage(sender());
return (WOActionResults) lpi;
}
the call to: .valueForBinding("dataSource") seems wrong since it
depends upon the parent of the ERDControllerButton to have the
datasource, which is not always true.
What would be the proper way to get the dataSource?
