Way for pages to intercept errors easily
----------------------------------------
Key: TAPESTRY-1724
URL: https://issues.apache.org/jira/browse/TAPESTRY-1724
Project: Tapestry
Issue Type: New Feature
Components: tapestry-core
Affects Versions: 5.0.5
Reporter: Howard M. Lewis Ship
It would be nice if there was a way pages could define an event handler that
would be notified in the event of an exception while processing the page; it
should be passed the exception and some indicator (an enum) of where the
exception occured. This would allow a way for individual pages to handle
certain exceptions in a specific way.
A particular use case for this would be handling the case where parameters can
not be coerced when invoking an activate event handler method, but there's
quite likely many others.
