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)

er.directtoweb.ERD2WFactory.pageForConfigurationNamed(ERD2WFactory.java:169)

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 _______________________________________________
