[jira] [Resolved] (WICKET-6189) Return Optional from RequestCycle.find(Class)

["Sven Meier (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/WICKET-6189?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sven Meier resolved WICKET-6189.
--------------------------------
       Resolution: Fixed
    Fix Version/s: 8.0.0-M1

Having two methods (one returning ART and one Optional<ART) isn't something we want to support, so #find() return the optional now as powwowed.

I've added a warning to the migration guide.

> RequestCycle.find(Class<T>) is mostly used to get the current AjaxRequestTarget.
> Since the returned reference might be null (in case of a non-Ajax request), it would be better to return an Optional<AjaxRequestHandler>.
