Description

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()));
