[jira] Commented: (SHALE-336) Exceptions raised in action listeners are exempt from the exception handing strategy of the view controller.

Craig McClanahan commented on SHALE-336:
----------------------------------------

The patch looks pretty good ... it covers the case of application defined action listeners quite nicely.  I'm wondering if this might even make the catching in ViewActionListener redundant?

We should also look at extending this idea to deal with value change listener events too, if it can be done in a similar fashion.

> 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.
