Page Class in PageExpiredException
----------------------------------
Key: WICKET-4013
URL: https://issues.apache.org/jira/browse/WICKET-4013
Project: Wicket
Issue Type: Improvement
Components: wicket
Affects Versions: 1.5-RC7
Reporter: bernard
We need to recover the page class from PageExpiredException.
Something like PageExpiredException#getPageClass() and
PageExpiredException#getPageParameters().
In principle, the page class is recoverable from the page URL if the page is
mounted. This is easily achievable in Wicket 1.4. In Wicket 1.5, there are some
complications, but these are not the subject of this Jira issue.
Even if the page class is not recoverable in all cases, and PageParameters are
yet more difficult to obtain, the concept of maintaining fields in
PageExpiredException would clarify and help drive these basic issues towards
resolution.
That is because the required information about the failing page lookup i.e. the
path is most likely available exactly where this exception is thrown.
In other words, a PageExpiredException without the key information of what
actually expired is not very helpful.
