| Hi all,
I would like to be more useful to the list, contributing with answers more than I ask for help, but I must ask for help again.
I am trying to implement a D2W application as much as possible reusable and tried the following code in my MainNavigationController:
public WOComponent listAnEntityAction() { return listPageForEntityName(AnEntity.ENTITY_NAME); } … private WOComponent listPageForEntityName(String entityName) { ListPageInterface newListPage = (ListPageInterface)D2W.factory().pageForConfigurationNamed("List" + entityName, session()); EODataSource ds = new EODatabaseDataSource(ERXEC.newEditingContext(), entityName); newListPage.setDataSource(ds); return (WOComponent) newListPage; }
But the end result is an exception that I was not able to track to D2WContext:
ClassCastException: java.lang.String cannot be cast to com.webobjects.eoaccess.EOEntity at com.webobjects.directtoweb.D2WContext.entity(D2WContext.java:394) at com.webobjects.directtoweb.ERD2WContext.setDynamicPage(ERD2WContext.java:103) at er.directtoweb.ERD2WFactory.pageForConfigurationNamed(ERD2WFactory.java:169) at com.visionar.administraAgencia.app.MainNavigationController.listPageForEntityName(MainNavigationController.java:95) at com.visionar.administraAgencia.app.MainNavigationController.listAgênciasAction(MainNavigationController.java:32)
I have already implemented a navigation menu with page configurations but with a lengthier code, but I think this style is more reusable and concise. I searched the examples and was able to see that the BugTracker and ERMovies examples implement actions and page configurations in this style, so I think I'm not doing something overly wrong.
Cheers,
Angelo |
