------------------------------------
Summary: Stateless pages are not rendered anymore before executing
a behavior
Key: WICKET-6616
URL: https://issues.apache.org/jira/browse/WICKET-6616
Project: Wicket
Issue Type: Bug
Components: wicket-core
Affects Versions: 8.2.0
Reporter: Thomas Heigl
I just upgraded from 8.1.0 to 8.2.0 and a bunch of my tests broke. A required
form component on a stateless page that is hidden in "onConfigure" started to
report an error after the upgrade.
The problem was introduced in WICKET-6608 by this commit:
[https://github.com/apache/wicket/commit/147f6d33f839edd9a6eb53ce9c20b4cde07fc938]
Previously, the page was initialized *and* rendered before returning the
component. Now, for some reason, the page is initialized and the component
returned immediately if it exists. This breaks all visibility/enabled
conditions that are evaluated later in the life cycle of stateless components.
