Detailed Description
Simple class that makes creating flows of pages a bit easier. Instead of the normal (sender instanceof ...) in nextPage(), you can implement methods nextPageFromSomePageConfiguration() or nextPageFromPageNameOfCurrentPage(). For example:
public class CreateAssetWithSelectionDelegate extends ERDFlowDelegate {
public WOComponent nextPageFromSelectAssetGroups() {
ERD2WListPage page = parent(ERD2WListPage.class)
if(page.selectedObjects().count() > 0)
...
return D2W.factory.pageForConfigurationNamed("CreateAsset");
return page.pageWithName("MaybeNextTimePage");
}
public WOComponent nextPageFromCreateAsset() {
ERD2WInspectPage page = parent(ERD2WInspectPage.class)
if(page.wasObjectSaved())
return page.pageWithName("ThankYouPage");
return page.pageWithName("MaybeNextTimePage");
}
}
...
D2WPage page = D2W.factory.pageForConfigurationNamed("SelectAssetGroups");
page.setNextPageDelegate(new CreateAssetWithSelectionDelegate())
...
