$bean syntax for validators: binding prefix is broken
-----------------------------------------------------
Key: TAPESTRY-610
URL: http://issues.apache.org/jira/browse/TAPESTRY-610
Project: Tapestry
Type: Bug
Components: Framework
Versions: 4.0
Environment: beta-5
Reporter: Howard M. Lewis Ship
Priority: Critical
The validators: prefix accesses the page's engine property before it is set:
public BeanProvider(IComponent component)
{
_component = component;
IEngine engine = component.getPage().getEngine();
_resolver = engine.getClassResolver();
if (LOG.isDebugEnabled())
LOG.debug("Created BeanProvider for " + component);
}
Stack Trace:

The validators: prefix needs to resolve bean names to beans *late*, at runtime
rather than at page-load time.
