Hi,
I have an AuthenticationFilter Class with the following code snippet:
private boolean dispatchedToLoginPage(String pageName) throws
IOException {
Component page = componentSource.getPage(pageName);
if (loginPage.equalsIgnoreCase(pageName)) {
URL lastPage = urlHelperService.getUrl(((Login)
page).getLastPage());
The page component is my Login page and I want to access the getLastPage
method of this class but I get the following exception:
25.05.2012 11:24:02 (DefaultRequestExceptionHandler.java : 63)
ERROR - Processing of request failed with uncaught exception:
