> Key: WICKET-2092
> URL: https://issues.apache.org/jira/browse/WICKET-2092
> Project: Wicket
> Issue Type: Bug
> Components: wicket-auth-roles
> Affects Versions: 1.3.5, 1.4-RC1
> Reporter: Juri Prokofiev
> Assignee: Juergen Donnerstag
> Priority: Minor
> Fix For: 1.4-RC3
>
>
> If HomePage don't have a default constructor there seems to be a problem with
> SignInPanel -- after the form submission an exception occured:
> java.lang.IllegalArgumentException: wrong number of arguments.
> The following code in DefaultPageFactory class might be bogus:
> if (argument != null)
> return (Page)constructor.newInstance(new Object[] { argument });
> else
> return (Page)constructor.newInstance(new Object[] {});
> Quickfix for solving the problem - replace "(PageParameters)null" with "new
> PageParameters()":
> setResponsePage(getApplication().getSessionSettings().getPageFactory().newPage(getApplication().getHomePage(),
> new PageParameters()));
