Exceptions raised in action listeners are exempt from the exception handing
strategy of the view controller.
------------------------------------------------------------------------------------------------------------
Key: SHALE-336
URL: http://issues.apache.org/struts/browse/SHALE-336
Project: Shale
Issue Type: Improvement
Components: View
Affects Versions: 1.0.4-SNAPSHOT
Reporter: Gary VanMatre
Priority: Minor
Attachments: view.patch
The action listener events are fire by the lifecycle in the invoke application
phase. If an exception is raised, there is not a trap similar to the
ViewActionListener for handling action event invocation exceptions.
In an attempt to make the error handing strategy consistent between the two
types of application callbacks, I propose that we subclass the view root and
override the processApplication method. Within this overridden method, we trap
the exceptions and add them to the exceptions list.
I'm not sure what side effects this might have but I thought it should be
discussed first.
