[jira] Updated: (TAPESTRY-423) An exception while constructing the RequestCycle causes an NPE
[ http://issues.apache.org/jira/browse/TAPESTRY-423?page=all ]
Howard M. Lewis Ship updated TAPESTRY-423:
------------------------------------------
Summary: An exception while constructing the RequestCycle causes an NPE (was: Referncing page via service url throws an exception)
The issue is that the monitor is not created until after the request cycle, so if creating the request cycle fails, NPE invoking the monitor.
try
{
cycle = _infrastructure.getRequestCycleFactory().newRequestCycle(this);
monitor = cycle.getMonitor();
service = cycle.getService();
monitor.serviceBegin(service.getName(), _infrastructure.getRequest()
.getRequestURI());
// Let the service handle the rest of the request.
service.service(cycle);
return;
}
catch (PageRedirectException ex) { ... }
}
catch (Exception ex)
{
monitor.serviceException(ex); // Line 264

> If I enter the following url in my web browser: http://scottwalter.com/app?service=page/InProgress I get the exception below. The work around was to use the friendly url version of the url which is http://scottwalter.com/. However this functionality worked in 3.0
